A damaged RFD may function prematurely, causing serious bodily injury or death, or fail completely. WARNING Hazardous voltages exist inside the receiver unit. Do not strike, tamper with, or attempt to remove or investigate the contents. Tampering with this equipment may damage the RFD and can cause serious bodily injury or death. WARNING Always test-fire the receiver/transmitter combination up range, set on the channel to be used, prior to priming. Separate receivers by not less than 2 feet when testing more than one receiver. Test with minimum of 6 feet separation between transmitter and receiver. A general procedure for test-firmg is provided in paragraph 3.3.1. Failure to confirm proper operation of the RFD may cause serious bodily injury or death. WARNING Hazardous, potentially fatal voltages exist on the metal binding posts when the RFD is fired. Contact with the posts may result in serious bodily injury or death. The binding posts are shunted and electronically isolated from the high voltage circuitry prior to firing, and again one second after firing. CAUTION Do not store batteries in the RFD when it is not in use. Long-term storage of batteries may damage the equipment. CAUTION Do not use lithium batteries with the RFD. Use only alkaline, 1.5-volt, AA batteries for operation of the RFD. 2.0 INTRODUCTION 2.1 Purpose This manual provides users with basic information for effective use of the RFD. 2.2 Scope This manual describes operation and maintenance procedures for the RFD. It sets forth the applicable safety requirements and safety precautions. Safety precautions include those applicable to (1) handling the RFD, (2) preparing the RFD for firing, and (3) interfacing the RFD with either shock tube or electric caps. This manual is intended to provide a broad and sound basic knowledge for operating and maintaining the RFD. It is not intended to establish or supercede existing local agency policies or procedures. 3.0 RFD DESCRIPTION ETI developed the RFD to be a reusable device for remote initiation of shock tube and electric detonators, powered by commercially available batteries. The RFD is capable of remotely initiating either electric detonators or shock tube devices by radio from a safe distance. Each RFD set consists of one transmitter and multiple receivers. Both transmitter and receiver include a rotary switch to select one of five available channels. Receivers may all be set to fire on one channel, each on a different channel, or in any combination thereof. Under ideal line-of-

sight conditions, functional ranges of 1,000 meters are possible. This system is intended for use by qualified law enforcement agencies, military units, and professional demolition personnel. All personnel engaged, whether directly or indirectly, in the operation of the RFD should thoroughly review and understand this manual prior to using it. 3.1 Definition of Terms The following terms are applicable to RFD operations. Explosive Ordnance Disposal (EOD) - The detection, identification, field evaluation, rendering safe, recovering, evacuation, disposal, and reporting of explosive ordinance or improvised explosive devices that have been fired, dropped, launched, projected, or placed as to constitute a hazard to operations, installations, personnel, or material. EOD also includes the rendering safe and/or disposal of items that have become hazardous or unserviceable by damage or deterioration when the disposal of such items is beyond the capabilities of personnel normally assigned the responsibility for routine disposition. Electric Cap - Caps which are electrically initiated, including both conventional electric blasting caps, and exploding bridgewire (EBW) caps. 3.2 RFD Controls and Indicators This section describes the controls and indicators for both the RFD receiver and transmitter units. Procedures for operating the transmitter and receiver are separately described later in this chapter. Receiver Transmitter Epa FF ow Receiver iv f Receiver Receiver Receiver Figure |.

The receiver is clearly distinguishable from the transmitter by the bright yellow background on the receiver faceplate. The transmitter faceplate is red. Preprinted adhesive labels are provided with each kit to allow the user to assign each receiver with a numerical identifier. This is helpful in operations employing multiple receivers. Each receiver has three control switches/knobs and three Light Emitting Diode (LED) status indicators. The switches on the receiver are:

1) POWER toggle switch. Applies power to the unit. 2) CHANNEL SELECT rotary switch. Selects one of five communication channels for the receiver. Available channels are 1-5. NOTE The unit reads the CHANNEL SELECT switch at the beginning of the safe separation period. Changing the setting of this switch after the ARM switch is engaged will not affect the channel setting. 3) ARM/SAFE toggle switch. Arms the unit. The three status indicators are:

1) Ared ARM STATUS LED 2) A green POWER ON LED 3) A yellow LOW BATTERY LED The green POWER ON LED is lit whenever power is applied to the unit (i.e., the power switch is in the ON position). The yellow BATTERY STATUS LED indicates the energy level of the batteries The red ARM STATUS LED indicates the current armed state of the RFD receiver Table 1 indicates possible combinations of the yellow BATTERY STATUS and red ARM STATUS LEDs. Table 1. RFD Receiver BATTERY STATUS and ARM LED Status Indications. ARM STATUS LED BATTERY STATUS CONDITION LED OFF ON Batteries are very weak. Further operation is inhibited until the batteries are replaced. OFF FLASHING Batteries should be replaced soon. Further operation is permitted. FLASHING ANY | Arm switch has been placed in armed Short blink once every position. Receiver will start to generate two seconds. and store firing energy in two minutes. FLASHING T ANY Beginning two minutes after arm switch Longer flash once every has been placed into ARM position. Unit two seconds has begun to generate and store firing energy. ON OFF or FLASHING | Beginning 5 minutes after receiver placed in ARM mode, unit is armed and awaiting a FIRE command. FLASHING ANY Unit has received a valid FIRE Four times per second. command. ON ON A fault condition has been detected. See section 3.7 for troubleshooting procedures. NOTE The RFD supplies its own energy. No external input power is required. NOTE A flashing BATTERY STATUS LED indicates at least one hour of operation is guaranteed, but batteries should be replaced immediately if practical. A fresh set of batteries provides up to six hours of receiver operation. NOTE After the ARM/SAFE switch is placed in the ARM position, the red ARM STATUS LED will blink once every two seconds for the first two minutes of the 5 minute safe wait period. During this initial two minutes the receiver is in standby and not generating and storing any firing energy to the firing circuit. After the initial 2 minutes of the 5 minute safe wait the LED will flash for a longer duration as the receiver begins to store firing energy to the firing capacitor until the full 300 volts of firing energy is stored. At this point the receiver will maintain the firing energy until the safe separation time of five minutes has expired. After that, the ARM STATUS LED will remain ON. NOTE The red ARM STATUS LED will blink four times per second once a valid FIRE command has been received. The LED will continue to blink at this rate until power is lost or the receiver turned off. Two spring-loaded binding posts are located at the top of the receiver. The binding posts are designed to connect to either electric caps, or to the STInger shock-tube adapter included with each receiver. To use shock tube, the STInger shock tube adapter (see figure 3) must be attached to the receiver. The STInger is attached to the receivers binding posts by pressing the spring clips on the rear of the STInger onto the binding posts. No screws are required. Figure 4 is a receiver unit with STInger attached. If shock tube to be employed the following procedure should be followed to connect the shock tube to the STInger adapter. a Trim ends of shock tube. b. Loosen the plastic knob (turn counter-clockwise). C. Insert cut length of shock tube through the hole in the plastic knob until fully seated. d. Tighten the plastic knob (turn clockwise). Tug on tubing to insure that the attachment is secure. e. Once the unit has fired, loosen plastic nut and remove fired tubing. NOTE The white shock tube compression nut shown in figure 3 accepts shock tube that is nominally 0.120 inches in diameter (with a maximum diameter of 0.128 inches). Larger diameter shock tube (0.150 nominally) used by some military agencies will not interface with the STInger with the standard white compression fitting. ETI has a green colored compression fitting suited to this larger diameter shock tube which has been included in your kit. CAUTION The retaining nut should be finger-tightened only. Over-tightening the retaining nut may damage the unit. Standard Commercial Type ee Shock Tube _ Military Type 0.120 diameter Shock Tube nominal 0.150 diameter Rominal White _ Compression |. Nut Figure 3. STInger shock tube adapter with plastic tubing fitting retaining nut. Figure 4. RFD receiver configured with STInger shock tube adapter. The receiver unit may also be used with electric caps (see figure 5). The contact wires should be attached directly to the spring-loaded binding posts. Attach one contact wire to each spring-loaded binding post, as follows:

1. Press down on the spring-loaded binding posts to open the wire connection. 2. Insert the wire into the opening and release to clamp the wire. Approximately 4 -

inch of insulation should be removed from the end of the wire prior to making the connection to the spring-loaded binding posts. Figure 5. RFD receiver configured for use with electric caps. 10 3.2.2 Transmitter Unit Controls and Indicators Figure 6. RFD transmitter unit controls and indicators. 1]

The transmitter (red faceplate) has four control switches and three LED status indicators. The switches are:

1) POWER toggle switch. Applies power to the unit 2) CHANNEL SELECT rotary switch. Selects the communication channel for the transmitter. Channels 1-5 are available. 3) ARM key switch. Allows FIRE commands to be sent. The key should be removed as a safety measure while the receivers are being placed. The arm key is locked into the key switch when in the ARM position. Key may only be removed when switched to the SAFE position. 4) FIRE toggle switch. Sends FIRE commands to the receivers. The three status indicators are:

1) Ared ARM STATUS LED. 2) A green POWER ON LED. 3) A yellow BATTERY STATUS LED. The green POWER ON LED is lit any time power is applied to the unit (i.e., the power switch is in the ON position). The yellow BATTERY STATUS LED indicates the energy level of the batteries. The red ARM STATUS LED indicates the current armed state of the RFD transmitter. Table 2 indicates possible combinations of the yellow BATTERY STATUS and red ARM STATUS LEDs. Table 2. RFD Transmitter ARM STATUS LED and BATTERY STATUS LED Indications. ARM STATUS LED BATTERY STATUS LED CONDITION OFF ON Batteries are very weak. Further operation is inhibited until the batteries are replaced. OFF FLASHING Batteries should be replaced soon. Further operation is permitted. FLASHING ANY Unit is transmitting a FIRE command. ON OFF or FLASHING Unit is armed and ready to transmit a FIRE command. ON ON A fault condition has been detected. See section 3.7 for troubleshooting procedures. 12 3.3 Method of Operation A test firing should always be performed up range before an actual initiation. A typical test firing sequence is provided below. Live firing procedures are provided in paragraph 3.3.2. 3.3.1 Test Fire Procedures Test fire procedures are generally specified by local agency policy and should always be completed before live firing the RFD. In the absence of local test firing procedures, use the following general procedure. 1. 2. 10. 11. Remove transmitter and receivers from their containers and inspect for damage. Insert batteries in transmitters and receivers. Install antennas on transmitters and receivers. Install STInger shock tube adapters on all receivers. Set each receiver on a different channel. Power each unit ON and ensure the battery light is not illuminated. If the battery light is illuminated, replace the batteries. Set each receiver ARM/SAFE key switch to ARM. The key is locked into the key switch when in the ARM position. Place each receiver in the order of channel selection (1 through 5), with each receiver antenna oriented vertically. Each unit should be no closer than 2 feet from any adjacent receiver and not less than 6 feet from the transmitter. Wait until all receiver units ARM lights display solid red, indicating units are ready to fire. Remove locking pins from transmitter unit and set transmitter to ARM. Move at least 6 feet away from the receiver(s). Fire each receiver in channel selection order (one through five) and observe to ensure each STInger fires. WARNING In the event of a misfire, during test firing, do not use the failed receiver with live explosives. Follow troubleshooting procedures in paragraph 3.7 to determine the cause of the misfire. 13 3.3.2 Live Fire Procedures 1. Perform a site survey to determine positioning of the transmitter, receiver, detonator, and explosives. 2. Test fire the RFD according to local agency procedures. Do not use the RFD with live explosives until a test fire is successfully completed. WARNING The RFD should always be test fired up range, following local agency procedures, before using live explosives. An RFD which has not been test fired may malfunction, resulting in serious bodily injury or death. A typical test firing procedure is provided in paragraph 3.3.1. 3. Secure detonator by placing it in the ground or covering with sandbags. Ensure the detonator or tool is not in contact with explosive materials. CAUTION Protect the RFD from potential blast damage by distance, shielding, and cover. Units not adequately protected from blast may malfunction or fail completely. 4. At the receiver unit:

Step 1: | Ensure the power switch is turned OFF. Step 2: Attach the device (shock tube or electric caps) to be initiated. Step 3: Turn POWER switch to ON. Step 4: Set the CHANNEL SELECT switch to the desired channel ID. Step 5: | When ready to fire, the receiver arming sequence may be started by placing the ARM/SAFE switch in the ARM position. The time should be recorded and a stopwatch started at this point, since the transmitter gives no indication of when the safe separation period is over. Upon completion of step 5, the ARM STATUS LED will begin flashing and will continue to do so for five minutes. The flashing state is an indication that the unit is operating in the five-minute safe separation period. During this time, commands received over the radio link are ignored. At the completion of the safe separation period, the ARM STATUS LED goes to a steady ON state. Should a validated fire command be received from the transmitter, the unit fires, and the ARM STATUS LED flashes approximately four times per second. All indicators remain in this state until power is cycled (turned off, then back on) on the receiver. 14 At any time before firing, the ARM/SAFE switch may be placed into the SAFE position to immediately return the receiver unit to the SAFE condition. Restoring the switch to the ARM position starts a new five-minute safe separation period. NOTE If there is any possibility of the ARM or POWER switches being displaced prior to the firing of the receiver, (for example, due to vibrations from nearby detonations), the switches may be locked in the ON and ARM positions by inserting the supplied locking pins through the holes in the switch guards. 5. Prime the explosive charge. WARNING Do not touch the RFD receiver after the explosive charge has been primed. NOTE The RFD should not be relied on to function properly if left in an armed state for more than six hours. 6. At the transmitter unit:

Step 1: | Ensure the power switch is turned OFF and the ARM/SAFE switch key is removed. Step 2: _ Ensure all personnel are at a safe distance from the detonation area. Step 3: Turn the POWER switch to ON. Step 4: Set the rotary switch to the desired Channel ID. Step 5: Insert the key into the ARM/SAFE switch. Step 6: Place ARM/SAFE switch in the ARM position. The ARM STATUS LED will light. 7. When ready to fire:

Step 7: Remove the locking pin from the FIRE switch guard. Step 8: To fire, momentarily push the FIRE switch to the FIRE position and hold, then release. The ARM STATUS LED will briefly flash during transmission of the FIRE command. After step 8 has been completed, the rotary switch may be turned to a different channel and the FIRE switch pushed to fire any receiver(s) located on that channel. Channels may be re-

selected only between FIRE commands. Wait for the ARM LED to stop flashing before pushing the FIRE switch again. 15 WARNING In the event of a misfire, safe procedures must be followed. See paragraph 3.5 for misfire safe procedures. 3.4 Line-of-Sight/Radio Considerations The RFD transmitter and receiver have been tested to operate at a separation distance of up to 1000 meters. Significantly longer distances may be possible under ideal conditions. This assumes a clear line-of-sight between transmitter and receiver, i.e., in a flat area, and with no obstructions between the two. One thousand meters may not be attainable in urban environments due to the presence of obstructions (such as RF-absorbing/reflecting walls and other surfaces) and extensive interference from RF emitting devices such as cellular telephones. There should also be a minimum of 6 feet separation between the transmitter and receiver, a distance of several wavelengths at to transmitter frequency. The RFD may not function reliably at distances of less than 6 feet. NOTE At distances of greater than 1000 meters, it may be necessary to elevate the receiver from the ground slightly to ensure good reception. Elevation of as little as one foot above the ground can often provide greater reliability at these longer distances. NOTE For maximum range, antennae for both transmitter and receiver should be vertically oriented (facing up). 3.5 Safe Procedures in the Event of Misfire Procedures for handling a misfire are generally specified by agency policy and should be followed. General procedures in the event of a misfire are as follows:

Step 1: On the transmitter, turn the ARM/SAFE key switch to the SAFE position and turn the transmitter POWER switch OFF. Step 2: Maintain a safe distance from the receiver for at least 30 minutes after the misfire. Step 3: After 30 minutes have elapsed since the misfire, approach the detonator. Do not touch the RFD. Step 4: | Remove any sandbags or soil covering the detonator and detach the detonator from the main charge. Step 5: | Remove the electric detonator wires or shock tube from the RFD. Step 6: The RFD may now be safely handled. Note the status of the ARM and POWER lights before powering the receiver OFF. 16 Step 7: Follow troubleshooting procedures in paragraph 3.7 to determine the cause of the misfire. Step 8: If the cause of the misfire can be determined, correct the problem, then perform a test fire following the procedures in paragraph 3.3.1 If the cause of the misfire cannot be determined, use a different RFD, perform a test fire following the procedures in paragraph 3.3.1, replace the detonator or shock tube, and repeat the firing procedure in paragraph 3.2.2. NOTE Appendix B is a Malfunction Report Form. Please use this form to report malfunctions of the RFD to ETI. 3.6 Power The RFD is powered by three internal alkaline, 1.5-volt, AA batteries. No external power supply is required. See paragraph 4.1 for battery replacement procedures. 3.7 Troubleshooting Q: The indicator lights remain dark when the unit is powered up. A: Check the batteries for correct orientation and try again. If this does not help, try replacing the batteries. QO: The POWER, ARW/SAFE and BATTERY STATUS indicators all light and remain lit. A: This indicates an internal failure has been discovered by the unit. Try cycling power. If this condition continues to occur, the unit should be replaced. QO: A FIRE command was sent by the transmitter to the receiver and no detonation occurred. A: Follow misfire safe procedures (see section 3.5). Before powering down the receiver, observe the state of the ARM STATUS indicator. If the indicator is not flashing rapidly, check the CHANNEL SELECT switch to ensure the receiver and transmitter are both set to the same communication channel. Verify the antenna is securely attached to both transmitter and receiver. Also verify a clear line-of-sight is available for communication between the transmitter and receiver. A rapidly flashing ARM STATUS indicator indicates communication between transmitter and receiver was successful, but something prevented energy from being supplied to the detonator. Check for good electrical contact being made between the binding posts and the device being initiated, whether through electric cap wires or the STInger. Check the batteries. 17 4.0 MAINTENANCE WARNING Hazardous voltages exist inside the receiver unit. Do not strike, tamper with, or attempt to remove or investigate the contents. Tampering with this equipment may damage the unit and can cause serious bodily injury or death. There are no user-serviceable parts in the unit. 4.1 Battery Replacement NOTE A flathead tool, such as a flathead screwdriver or a coin, is useful for replacing the batteries. For maximum longevity, replace the batteries with each use. Three alkaline, 1.5-volt, AA batteries are required for each transmitter and receiver. The RFD is designed to allow battery replacement with minimal tools (e.g., a flat-head screwdriver, a dime, or even a fingernail). Before replacing the batteries, turn the ARM/SAFE key switch to the SAFE position and turn the POWER switch to the OFF position. Leave power off for at least five minutes. a. Turn the battery cover screw with a screwdriver or coin counterclockwise, as shown in figure 7 and figure 8. The screw is captured in the cover ee +______ Battery cover screw Figure 7.

Figure 8. Battery compartment cover removal. b. Remove the cover and replace the old batteries with new ones. Check battery orientation

(see figures 9 and 10) before insertion. The battery compartment is keyed so inserting the batteries improperly will not damage the unit. c. Re-install the battery cover. d. Hand-tighten the securing screw. Orient batteries as shown

| Battery cover and screw Figure 9, Battery orientation. 19 Figure 10. RFD with battery compartment cover removed. CAUTION Do not over-tighten screw. Over-tightening screw may strip screw threads or damage the RFD. 4.2 Re-carbonizing STInger Spark Ignitor The spark ignitor in the STInger relies on carbon residue to bridge to high voltage contacts providing a conductive path from which the spark is generated. The spark ignitors in the STInger were treated initially to apply this conductive carbon trace. Under normal conditions this carbon trace is regenerated each time the module is functioned. In some instances, the carbon deposition may fail to provide the conductive path necessary for spark generation. This condition may be promoted from long periods of disuse or operation in high humidity or exposure to moisture. The conductive carbon bridge may be easily re-established. As shown in figure 11, remove the shock tube compression nut from the module and set it aside. Insert a pencil lead into the bottom of the shock tube receptacle and apply a fresh coating of graphite. For best results use pencil leads for lead holders used in drafting and graphic arts. An initial supply of these leads have been provided with your kit. 20 Figure 11. Spark igniter re-carbonizing procedure. 43 Cleaning Keep the RFD free from dirt, dust, and debris. Use a mild soap, such as dishwashing detergent, and a dampened rag for topical cleaning. The RFD is designed to be water-resistant, but should never be immersed in water. CAUTION Do not use any solvents, harsh cleaning agents, or cutting fluids on the RFD. Use of these agents/fluids may damage the unit. 21 44 Kit Serialization and Module Replacement Each module in a RFD Kit is assigned a unique serial number. This serial number as well as the identity of your agency is included in the digital, encrypted fire command that is sent from the transmitter to the receiver. A transmitter is capable of initiating receiver units only from its kit. No receiver will accept a fire command from any transmitter other than the transmitter programmed for its kit. Although any number of receivers are available in a single kit, ETI will not provide more than one transmitter per kit. The transmitter and receiver serial numbers are printed on the label on the back of each module. The format of the serial number is;

Transmitter; T 0001 01 ROO Receiver #1: R 0001 01 R00 Receiver #2: R 0001 - 02 ROO YS N.Y NYY NY Module Type Kit No. Serial No. Revision No.

(Tx or Rx) NOTE If your agency has purchased more than one RFD Kit, you will need to keep the modules together by kit number. Avoid mixing transmitters and receivers from different kits. Additional receivers or replacements may be ordered from ETI and programmed to accept the firing code from the pre-existing kit. Please specify your user agency and the kit number with your order. In the event your transmitter is damaged or lost, you may order a replacement transmitter as well. When ordering a replacement transmitter for an existing kit you will need to return all of the receiver modules. The receiver modules will be reprogrammed to accept the new firing code to match the replacement transmitter. This is done as a precaution to insure that no two transmitters will be able to initiate the same set of receivers. 22 APPENDIX A RADIO FREQUENCY REMOTE FIRING DEVICE UNIT USAGE AND TEST LOG SERIAL NUMBER DATE amen INITIALS |

Introduction The World Wireless 900 SS MicroHopper is a frequency hopping data transceiver radio designed for integration with other products. The 900 SS MicroHopper is connected to a host device using a 20-pin dual in-line header. This connection provides the radio with the required DC power source and allows the 900 SS MicroHopper to be programmed, configured, and provides I/O lines for a TTL level RS-232 port. The 900 SS MicroHopper operates within the 900 MHz ISM Band and operates under Part 15 or the FCC Rules and Regulations. Because it is made for integration with other products the 900 SS MicroHopper is designed for professional installation. The 900 SS MicroHopper allows OEMs to integrate the radio into their own systems. When installed using a World Wireless Communications approved antenna, the system integrator needs to make sure the 900 SS MicroHoppers FCC label, or a copy of that FCC label, is clearly visible on the outside of the integrated product. 900 SS MicroHopperUsers Guide page 1 World Wireless Communications, Inc. Worldwide Wireless 900 SS MicroHopper Features Using Spread Spectrum (SS) technology means the 900 SS MicroHopper is highly secure and is resistant to noise and interference To increase the security of the radio signal, World Wireless Communications developed Secure-Sync technology. This proprietary coding feature adds security, throughput efficiency, and error detection. Secure-Sync provides faster effective communication speeds while enhancing the 900 SS MicroHoppers reliability. Features for the World Wireless 900 SS MicroHopper include:

Frequency Hopping Spread Spectrum Transceiver World Wireless Secure-Sync Technology

" Selectable transmission power, 100 milliwatts max. 19.2 Kbps RF data rate

* 500 Meters effective range*

" Cost-efficient

*" Easy-to-use Windows-based configuration software Range calculations are line of sight. Actual range will vary based on specific board integration, antenna selection, environment, and the OEM's device. The 900 SS MicroHopper can be used for many applications. Some examples are:

* Short/Long Distance Telemetry Supervisory Control and Data Acquisition (SCADA)

= Security and Access Control Environmental Monitoring and Control

" Production and Flow Tracking 900 SS MicroHopperUsers Guide page 2 World Wireless Communications, Inc. Installation The World Wireless 900 SS MicroHopper is configured before it is shipped. In most cases no configuration is necessary and the radios should work immediately when they are installed. Should the factory configuration need to be altered, the Radio Support Utility software allows you to configure the radio for your specific application. See the Configuring the Radio section for information on using the support utility. Site Requirements You should carefully plan for radio sites that ensure that strong and stable signals are received and transmitted. A good site provides the radio with the following:

Protection from direct weather exposure

= A power source

* Antenna location that is unobstructed Transmission Path The 900 SS MicroHopper operates in the 900 MHz (902-928) ISM frequency band. While this band offers many advantages for data transmission, radio signals travel primarily by line-of-sight. Signal loss due to obstructions such as terrain, foliage, buildings and other things that block the transmission path are possible. A line-of-sight transmission path between the host radio and the remote sites provides the most reliable signaling link. Signal Distances The importance of a clear transmission path relates closely to the distance to be covered by the radios. If the radios only cover a limited area, for example within 500 meters, some obstructions in the transmission path can be tolerated with minimal impact. For maximum range radio systems, any substantial obstruction in the transmission path will severely deteriorate or even block completely the radio signals. Testing Using RSSI An RSSI (Received Signal Strength Indicator) feature of the 900 SS MicroHopper can help you test the signal strength and background noise when determining site location (see RSSI Tab in the Configuring the Radio section for additional information on the RSSI feature). 900 SS MicroHopperUsers Guide page 3 World Wireless Communications, Inc. Configuring the Radio Use the Radio Support Utility to configure your 900 SS MicroHopper radio. Once the settings are configured and stored in the radio, those settings will remain the same, even when the radio is powered off. Note: Configuration settings are saved in non-volatile memory on the 900 SS MicroHopper radio. That means configuration settings are always saved, even if the power to the radio is turned off. If you are using the radio in a field device such as PLC, RTU, Data Logger, etc., and need to change the configuration settings, those changes can be done using the Radio Support Utility on a PC. Once the radio has been reconfigured attach it to the field device. The Radio Support Utility uses tabs to organize the MicroHoppers settings and features. To alter the configuration, select the tab of the section you want to change and alter the settings. Select Write to store the altered settings in the radio memory. 900 SS MicroHopperUsers Guide page 4 World Wireless Communications, Inc. Port Tab The Port Tab contains the serial COM port settings COM Options and the Terminal window display settings TTY Options. The PC communicates with the radio through the COM port. The Port Tab allows the user to select the COM port to which the 900 SS MicroHopper radio is connected. The serial interface used must be set to 8 Data Bits, No Parity, and 1 Stop Bit.

Only one serial communications software program can use this COM port at a time. If your radio is not connected to COM1, alter the COM port setting to match the COM port to which your radio is connected. If the COM port that appears in the Port Tab is not the COM port to which the radio is connected, an error message appears when you start the radio support utility or select another tab. If you see an error message, change the COM port setting to match the COM port to which your radio is connected. You will not be able to make changes to any of the radio settings until the PC is communicating with the radio through the correct COM port. Baud Rate-Port The default is 19,200. Sets the baud rate the PC uses to communicate. A drop-down menu allows standard baud rates from 1200 to 19200 bps. Caution: The Radio Support Utility uses two separate baud rates; the Baud Rate--Port found in the Port Tab, which is the communication baud rate of the PC or serial input device; and the Baud Rate-Radio found in the Settings Tab, which is the communication baud rate of the radios serial interface port. These baud rate settings must match for the radio and the PC to communicate effectively. If you choose another baud rate, make sure you also reset the Baud Rate-

Radio in the Settings Tab if you want the computer and the radio to communicate effectively. The 900 SS MicroHoppers Baud Rate-Radio highest setting is 19,200. Radio baud rates must match each other. 900 SS MicroHopperUsers Guide page 6 World Wireless Communications, Inc. TTY Options Used with the Terminal Window that appears when you select the Terminal Tab. These are the settings used by Terminal Mode and are not part of the radio settings. All three settings are checked on by default. Auto Wrap When checked, turns on Auto Wrap in the Terminal Window. Text characters automatically wrap when they reach the right edge of the window. When unchecked, wrapping is turned off. Note: You will need to use the horizontal scroll bar to see the full window. New Line When checked, terminal mode recognizes <Return> as a line feed and scrolls the screen up one line while starting a new line. When unchecked, characters are displayed on a single line and <Return> starts at the beginning of that single line. Local Echo When checked, characters being input are displayed in the Terminal Window. Local Echo causes each character to be sent to the receiving radio

(device) and also to be printed in the Terminal Window. When unchecked, characters are sent directly to the receiving radio and no display is given. Using Local Echo actually slows down communication speeds. If throughput speed is a concern, un-checking Local Echo can increase performance. Always un-check Local Echo when testing the transfer rate of the radio between the host device and the radio. If the radio (receiving device) has an Echo Utility you will see double characters as the character that was sent is returned to the host by radio. Echo utilities on the radio will also slow communication speeds and should be turned off when testing transfer rates. Font Button Sets the font and size of the characters displayed in the Terminal Window. Clicking on the Font button displays the Windows Character screen where you can change the font and its size. 900 SS MicroHopperUser's Guide page 7 Delivery Tab World Wireless Communications, Inc.

Pass Through ld(s) (Repeater Path) This is a list of radios the transmission must pass through to reach the Destination radio. Using the Options setting from the illustration above, Radio 1 would pass through Radio 2, Radio 3, and Radio 4 (the Pass Through radios) to send a point-to-point transmission to the Destination Radio 5. For the Radio 5 to respond its Pass Through order would be the opposite, that is4, 3, 2, because the transmission from 5 would have to go through a reverse order to reach Radio 1. A 0 ends the pass-through list. All values following the first O must also be 0. Configuring the Pass Through radios The pass through radio Destination ID requires a value; it may be set to any radio in the communications string. Set the pass through IDs to 0,0 Write these settings to the Pass Through radios.

to 02.0/ CIS BSAe Serial Baud Rate (Baud Rate-Radio) The default is 19,200. Sets the serial radio baud rate the radio uses to communicate. A drop-down menu allows standard baud rates from 1200 to 19200 bps. Caution: The radio CTS flow control must be monitored to insure the data source does not overrun the radio input buffer. These baud rate settings must match the slowest device in the communications chain to communicate effectively. 900 SS MicroHopperUsers Guide page 14 World Wireless Communications, Inc. If you choose another baud rate, the Baud Rate (Port) in the Port Tab will automatically be updated. Full Bi-directional communication is most effective when all the devices in the communications chain are at the same baud rate. One-way data transfer can be accomplished with the receiving devices at a higher baud rate than the source device. The radios will always broadcast to each other at 19.2kbps. The PC serial port may be set to any value equal to or greater than the radio baud rate. The communications software must be set to the baud rate of the radio serial port. TX Assert (bytes) The default is 122 bytes. Transmissions are sent when the buffer reaches the TX Assert (bytes) level. CTS Assert, CTS De-Assert, TX Assert (bytes), and TX Assert (mS) are all settings that manage input so that it is gathered together and sent in packets. Packets are sent when they reach the TX Assert (bytes) buffer level. The TX Assert setting should always be equal to or below the CTS De-Assert setting which defaults to 122 bytes. For details on CTS Assert/ De-Assert see Appendix C. TX Assert (mS) The default is 20 mS. TX Assert (mS) acts as a timeout. It is used to force transmission if the buffer fails to fill. It should always be set to slightly longer than the expected buffer fill time. Low values of this setting can cripple communications. If the input being stored waits for 20 milliseconds, TX Assert sends a transmission. When input is not constant, or when a small amount of input is left over from the previous transmission, the TX Assert (mS) setting ensures that all information is sent. Packet Transmission can be triggered by either buffer full or mS timeout. As part of flow control management, TX Assert (mS) always clears out the buffer by making a transmission based on a timing setting. Group Code The default is Group 1. The Group Code feature allows you to assign any number of radios to the same group. There are 1600 groups available in the Group Code setting. Radios that have different group codes will not communicate with each other. Radios with the same Group Code will communicate with each other. The Group Code is contained in the packet heading and only transmission packets with matching group codes will be recognized by those radios 900 SS MicroHopperUsers Guide page 15 World Wireless Communications, Inc. within the group. Using Group Codes is not the same as changing frequencies. TX Power (radio button) The default is High. The TX Power setting allows the user to change the transmitter output power. Power Save (radio button) The Default is Off. Power save options are not available for this radio. Default Button Click the Default button to see the factory default settings for the radio. The factory defaults are stored in memory and will appear when the Default button is clicked. However, to reset the radio to the factory defaults you must also click the Write buttonclicking Defaults and then selecting another tab, or closing down the Radio Support Utility will not reset the radio to the factory defaults. Read Button Click the Read button to have the configuration software read the current settings from the radio. Write Button Click the Write button to write the information from the configuration window (as it is currently set) to the radio. Use the Write button any time you want to change the radio settings to reflect what is entered in the fields. 900 SS MicroHopperUser's Guide page 16 World Wireless Communications, Inc.

~ Radio Support Utility To TS Ee Re 900 SS MicroHopperUsers Guide page 17 World Wireless Communications, Inc. How the 900 SS MicroHopper Works What is Spread Spectrum?

The 900 SS MicroHopper uses frequency-hopping signals instead of narrowband signals. The advantages of frequency hopping include traffic privacy, low probability of intercept, multiple access capability, and short synchronization time. With World Wireless Communications Secure-Sync technology, the 900 SS MicroHopper provides fast, reliable and secure radio communication. The 900 SS MicroHopper operates on 25 discrete frequencies within the ISM band; each frequency is about 400 kHz apart. Using a high-speed phase-locked loop synthesizer, the radio receiver is able to quickly acquire synchronization with the transmitter and receive the transmitted data. Data is transported across the RF channel in a transparent, promiscuous mode. This means that data sent into the serial port on one radio will be presented out of the serial port on all other radios that are within range and have the same group code. Connections The Data Radio is connected to a host device using a 20-pin dual in-line header for TTL mode. The radio requires external DC power delivered through the 20-pin header, an RS485 adapter or RS-232/DB9 adapter board for supported serial communications modes. These connections provide the radio with the required DC power source and allow the Data Radio to be programmed and configured, while providing I/O lines for an RS-232 port. Interference The radio shares frequency spectrum with other services and other unlicensed devices using the 902 Mhz to 928 Mhz frequency band. Systems that are installed in rural areas will encounter the least amount of interference, but because of the frequency sharing some level of interference is expected. However, the Hoppers flexible design and hopping technology should allow adequate performance as long as care is taken in choosing site locations. 900 SS MicroHopperUsers Guide page 18 World Wireless Communications, Inc.

5 VDC In Pass Through Configuration If using the TTL interface alone (radio only) DTR is High (configure) or Low (normal). Make sure DTR is grounded and that power and ground are applied to the radio interface connector. If connected to a PC through an interface board on a radio, make sure the terminal window is open (click inside the window). This will provide low DTR. 900 SS MicroHopperUsers Guide page 23 World Wireless Communications, Inc. Configuration Interface-Command Set If you wish to write your own configuration utility the following instructions apply. All data is binary using MSB order. Example: 9600 is sent (0x00, 0x00, 0x25, 0x80) Startup Setup 1. 6. When attempting to interface to the 900 SS MicroHopper through the 232 interface in command mode the first thing to do is to bring the DTR line low for RS232 interface or high for TTL (radio only) interface. Then wait 500ms. This is to give the 900 SS MicroHopper a chance to see the DTR change and to enter configuration mode. The 900 SS MicroHopper will then wait for the configuration key sequence or for the DTR line to go high (RS232) or low (TTL). If the configuration key sequence is received, the 900 SS MicroHopper will respond by sending the same configuration key sequence to the user. If the user receives the configuration key sequence they will know that they are officially in configuration mode. The configuration key sequence consists of 4 bytes: Oxf0 Oxaa Oxe4 OxOf To exit the configuration mode set the DTR line to high (RS232) or low (TTL). The radio will respond with 1 byte: OxOf. The Command Set The command set for interacting with the 900 SS MicroHopper in configuration mode follows:

COMMAND SET 900 SS MicroHopperUsers Guide page 24 World Wireless Communications, Inc. Command Examples SET_FREQ The command <0x03, FREQUENCY> where FREQUENCY is the 2 byte integer representing the frequency in 100 KHz sets the radio frequency. For example,

<0x03, 0x23, OxBE> sets the radio to 915.0 MHz. SET_RSSI The command <0x07, MODE>

where MODE is 0x00 for off, 0x01 for single channel, and 0x02 for scan, sets the RSSI mode. GET_RSSI_DATA The command <0x08> reads the radio frequency and RSS! data. The response format is <FREQUENCY, RSSI_DATA> where FREQUENCY is the 2 byte integer representing the radio frequency in 100KHz and RSSI_DATA is a 2 byte integer representing the signal strength. ERROR_ACCESS Error count clearing and reading is accomplished by first de-asserting DTR. Verify that the 4 byte configuration key is received at 9600 baud. SET_ERRORS Send the <Ox0a> byte to set the error count values to zero. GET_ERRORS To read error values send <0x09>. The radio will respond with 6 bytes of data as described below. The first 2 bytes are the errSyncByte. This value is either guaranteed or normal delivery. This value is incremented when the radio receive code has locked onto the data packet. The last byte transmitted is a special value to tell the receiver the packet is done. If the receiver exits the receive loop without seeing the special end of packet value, this count is incremented. The next 2 bytes are the lost packet count. The value is incremented in guaranteed delivery mode only. If the retry count equals the maximum number of retries, this value is incremented (i.e. no acknowledge was received). The last 2 bytes are the total retry count, which is incremented on each retransmission. 900 SS MicroHopperUsers Guide page 25 World Wireless Communications, Inc. Setting and Getting Configuration Data The following defines are used for the GET_CONFIG and SET_CONFIG commands. They have format <0x01, offset, length> for GET_CONFIG and <0x02, offset, length, data> for SET_CONFIG. The offsets are indicated and the length is in bytes. f#defne EE_BAUD_20 (11

For example to turn on guaranteed delivery a SET_GDINFO with an offset of 0, a length of 1, and a value of 1 would turn on the guaranteed delivery code.(the radio ID and destination ID would also have to have been set) The command would appear as follows <0x0e, 0, 1, 1> Write zeros for pass through ID's that are not used.

WARNING: Writing configuration data outside of the valid range may cause the radio to operate improperly. 900 SS MicroHopperUsers Guide page 27 World Wireless Communications, Inc. Troubleshooting Tips Radio is not responding If your radio is not responding, check the following settings to make sure both radios can communicate:

The Baud Rate for both radios should be set the same in the Radio Configuration window. Does the configuration information on both Radio Support Utility screens match? All of the settings in the configuration window must match for the radios to communicate effectively. Garbled characters appear in the Terminal window Does garbled text appear? If text appears, but appears garbled, the radios are set to different baud rate than the PC. Make sure that radios and the PCs are set to the same baud rate. Range is limited Check the antenna and make sure it is firmly attached to the unit. Remove any obstructions that are close to the radio (within a 5 foot radius). 900 SS MicroHopperUser's Guide page 28 World Wireless Communications, Inc. Glossary of Terms Baud Measurement of the signaling speed of a data transmission device. Baud rate and bits per second are not necessarily the same. CD Carrier Detect level. Used to tell the scanning radio if a transmitting radio is present. Communication (COM) Ports Designation of serial communications channels. COM port designations for this radio are COM1 through COM8. Configuration Default Operating characteristics of this data radio. The configuration default parameters are stored in the data radios non-volatile memory and are predetermined by the manufacturer. CTS Clear to Send. A control signal used in conjunction with Request to Send

(RTS) to perform data flow control. Flow Control A method used to regulate the flow of data between two devices. In this instance, between the customer DTE and the data radio. Group Code This setting is used to designate which group a radio will belong to. A radio will only hear other radios with the same group code. In Broadcast mode you may program up to 1600 different groups with unlimited radios in each group. When using Guaranteed Delivery mode a maximum of 256 radios may be assigned a unique radio ID. 900 SS MicroHopperUser's Guide page 29 World Wireless Communications, Inc. Modulation The shifting of transmit frequency representing the data being transmitted. Point to Point RF Signals Point-to- point describes a system where two radios exclusively share communications. All messages occur between the two radios. It is similar to wired communications between a host computer and a terminal. Point-to-Point signals can be passed through different radios, but the transmit (TX) and receive (RX) only occur on the two radios that share communications. Point-to-Multipoint RF Signals Point-to-multipoint describes a system where one master radio communicates with several remote radios. The remote radios only communicate with the master site, not with each other. Point-to-multipoint systems are built on addressing (See Group codes) , as the master radio must be able to specify which of the many remote sites is expected to receive and respond to the message. Preamble Length The length of time a transmitting radio sends a preamble to search for the receiving radio (180mS). The preamble is sent only when starting a new transmission on a new frequency. RF Data Rate How fast the transmitting radio sends data across the RF channel. RSSI Receive Signal Strength Indicator. Indicates signal strength on any given frequency. RTS Request to Send. A control signal used in conjunction with Clear to Send

(CTS) to perform data flow control. RX Buffer Size The RX (receiving) buffer size is the number of bytes stored in the receive buffer. 900 SS MicroHopperUsers Guide page 30 World Wireless Communications, Inc. Serial Baud Rate Baud rate the radio uses to talk to a PC or external device. TX Assert Amount of time or volume the transmitting radio will wait before it sends data. TX Buffer Number of bytes available for the transmit buffer. TX Power Transmitting power. This radio has 3 settings for range, preset by the manufacturer. Low (25mW), Med (50mW) and High (100mW)

APPENDIX B-RS485 INTERFACE Ground (Shield) Transmit A Transmit B Ground (supply) 8-30 VDC The RS485 standard for differential multipoint data transmission is ideal for transmitting high data rates over long distances in noisy environments. The interface is half duplex with peak data rates that are a function of distance (10Mbps at 40 feet to 100Kbps at 4000 feet). It will support up to 32 connections, however, the MicroHopper 485 interface board is terminated and the MicroHopper will transmit any data that appears on the bus. The MicroHopper 485 interface board was intended to provide a connection between a MicroHopper and a single device with a 485 interface. The MicroHopper itself is not addressable except through the Group Codes, Radio ID and Destination ID settings. Also, there is no flow control on the MicroHopper 485 interface board so data rates must be kept low to avoid buffer overrun. 900 SS MicroHopperUsers Guide page 34 World Wireless Communications, Inc.

FREQUENTLY ASKED QUESTIONS How Buffer Settings Work Note: For the examples found in this section, the default settings are used. The settings for flow control are found in the Settings Tab. The Radio Support Utility allows you to alter the TX Assert settings. Flow Control The basic idea behind flow control is that it maximizes the size of data that is being sent and received by the radio. The TX Buffer Size of 142 is the upper limit for the number of bytes that can be stored without an overflow. By managing the buffer size, overflows are prevented and throughput increased through the flow control settings. When the TX Buffer fills to the TX Assert (bytes) setting, a transmission is initiated. Buffer input (fill) occurs whenever memory space is available, gated by CTS. The default CTS Assert value is 112 bytes. The TX Assert (send threshold) should be less than or equal to the CTS De-assert value for the radio to transmit data. The default for both of these is 122 bytes. Timing for Flow Control A radio will cycle through the flow control settings in milliseconds, so the buffering and transmission process happens quickly. The only setting based on timing is the TX Assert (mS) setting. Once the input being stored waits for the selected number of milliseconds without any additional bytes being placed in the buffer, TX Assert sends a transmission. When input is not constant, or when a small amount of input is left over from the previous transmission, the TX Assert (mS) setting ensures that all information is transmitted. 900 SS MicroHopperUsers Guide page 36 World Wireless Communications, Inc. How Group Codes Work The Group Code should be considered a form of radio address. Group Codes do not affect the frequencies the radio uses. When a group of radios are assigned the same Group Code, a radio will only receive data from another radio using the same Group Code. Group Codes can be changed dynamically. Updates take approximately 1 sec. Data Rate Information The BAUD rate radio to radio is 19,200 (19200 BITS/second). The actual streaming data rate, end to end, is about 10,000 bits per second or about 1Kbyte per second assuming 8 data bits, 1 start bit, 1 stop bit. When streaming, data coming from the MicroHopper will be choppy because the radio has to stop every 400 mS to change channels. When using Guaranteed Delivery the data throughput is limited to approximately 2300 bits per second. The lowest baud rate is 1200 baud. Restricted Frequencies Here are some frequencies to avoid when integrating the radio into OEM systems. When selecting the switching frequency for the OEM power supply, oscillators, or clock signals avoid using both the indicated frequencies and any frequencies that would have harmonics on the indicated frequencies. TX/RX = 902-928 MHz. IF = 10.70 MHz. There may be other frequencies that could cause problems, but these would probably need to be determined by testing. 900 SS MicroHopperUsers Guide page 37 World Wireless Communications, Inc.

Wave: Astron AXH900RPSM Y% Wave: Astron AXQ900RPSM 900 SS MicroHopperUsers Guide page 38 World Wireless Communications, Inc. Interface Control Lines For asynchronous TTL, CTS is active low. CTS is set high when received data is being sent out the serial port. RTS should not be used. The radio ignores this line. To configure the radio, DTR must be held Low (TTL) or High (RS232) for the duration of configuration. Currently when initiating configuration mode, the radio will send out 4 bytes to indicate it has gone into configuration mode. You may then send the appropriate configuration commands. DTR must be set High (TTL) or Low (RS232) for the radio to receive or transmit. It should not be left unconnected. There is no Carrier Detect available to the user. The Reset (pin 7 on the 20 pin connector) is used by the factory for loading micro-code into the radio and should be left open by the user. With regards to the TTL interface the voltage levels are 0 (Low) and 3.6 volts (High). The DTE must be ready to accept incoming data at all times. Using the Configuration Command Interface Set DTR according to the interface used TTL or RS232, then SEND the initialization command to the radio. The radio confirms entry into configuration mode by sending an echo of the initialization command If invalid values are specified in a set configuration command to the radio, it will not operate properly. Valid values are listed as factory defaults. The memory map does not allow all configuration values to be read or written with one instruction. The modulation level parameter must always be set to zero (left unchanged) for compliance with FCC regulations. 900 SS MicroHopperUsers Guide page 39 World Wireless Communications, Inc. Guaranteed Delivery A one (1) enables guaranteed delivery mode and a zero (0) disables it from the configuration command set. This can also be activated at the delivery tab. Activating guaranteed delivery enables error (CRC checking) not correction. A packet with an error will be discarded from the point of the error to the end of the packet. The data prior to the error will be delivered. If the radio never gets an acknowledgement after the specified number of retries, there is no way to notify the host application. Packetization The packet size is affected by lots of different things (interface baud rate, response to handshaking, preamble length, TX Assert settings, Time in streaming mode. There is no way to predict what the individual packet lengths will be. The packet transmission will start after the first byte is received. The rate at which the transmit buffer empties will vary. Networking For data networking applications please see our X-NODE and X-GATE products. A MicroHopper cannot broadcast directly to a Hopper radio. However a Hopper and uHopper radio can be directly connected through the RS232 DB9 connector using a Null Modem connection. What the Hopper receives from broadcast is automatically placed on the RS232 bus and rebroadcast by the MicroHopper and vice versa.
