(MBCS) that allows short and long range communications between any two Stations in the system. The system offers continuous radio signal propagation via ground wave and meteor burst. Ground wave covers short distances, up to 100 km (60 miles). Meteor burst covers longer distances, up to 1,600 km (1,000 miles), reflecting signals off ionized electron trails created by meteors entering the atmosphere at a height of about 100 km (60 miles) above the earth's surface. These trails, called bursts, are random but predictable in number and last from a few milliseconds to several seconds. During this time, information can be exchanged between two Stations. The height of the trails (60 miles) gives the system its 1,000 mile range. 1.1 Presentation This manual is divided into five major sections:

The 545C can be used for sending and receiving messages, position reporting, data logging, or other specific applications. Designed to operate over a fading groundwave and an intermittent meteor burst communications channel, the unit's low standby-power consumption (<1 watt) makes it ideal for remote locations or mobile operation. The 545C features rugged construction in a weather-resistant enclosure that measures 10.6 " x 4.0" x 2.42" and weighs less than 3.5 pounds. A photograph of the 545C is given in Figure 2.1. The unit operates in a half-duplex mode and contains a solid state Tx/Rx switch that allows a common antenna to be shared for both transmit and receive. It can be operated with a single frequency or on two separate frequencies. The unit utilizes three phase locked frequency synthesizers to set the Tx and Rx frequencies. The operator can set the frequency to any authorized frequency (10KHz steps) within a 2 MHz band. Authorized frequencies can only be set at the factory by trained technicians. A factory technician is required to retune the transmitter and synthesizer if operation outside a 2 MHz band is desired. The unit can be factory tuned across the full 37 to 50 MHz band 2.2 Send and Receive Messages The 545C provides full text message capability. With a portable operating terminal, or a PC running terminal emulation software, you can exchange messages with any other Remote Station in the network. Messages may be plain text or binary data. They can be routed to single or multiple destinations or, to a Host Computer or Data Center. 2.3 Data Logging The 545C can be programmed to acquire, store, and transmit data from the various I/O signals noted below. Any analog or digital input can be used to trigger a transmission or to set a discrete output level. Output levels can also be set hi or low via a command received from a distant unit.

The MCC can also be connected via an RS 232 port to a variety of Data Loggers such as the Campbell Scientific CR10X or CR23. Data from these loggers can be collected, stored, and transmitted to a distant unit. Refer to Appendix B and E for a description of data logger interface. 2.4 Position Location The 545C delivers location data from either a built 12 channel GPS (optional) or from an external GPS with NEMA 0183 format, positioning equipment used in mobile units on land, in the air, and at sea. The 545C sends the position location to a Master or Base Station, which forwards the information to a Data Center or Host Computer for processing. This data can be used in dispatch centers, corporate/district offices, and other monitoring Stations for updating O&M of the MCC-545C PACKET DATA RADIO 12/2000 DESCRIPTION 2-10 map displays or additional functions. Refer to Appendix B for a description of the GPS commands. 2.5 Maintenance Features An operator terminal or a remote command from a distant unit can also be used to read and display the 545C's status such as radio propagation channel statistics, battery voltage during transmission (loaded), battery voltage when not transmitting (unloaded), RF forward and reflected power (checks antenna), and receiver noise levels. It can also be used to display and configure the 545C's operating characteristics, as detailed in Chapter 4. An internal Li ion battery is used to maintain the internal real time clock and battery backed RAM. This battery is capable of operating the clock in a power down state for a period of approximately 6 months. This battery should be removed if the unit is stored without power for extended periods of time. 2.6 Hardware Organization and Layout The unit contains five printed circuit assemblies:

A 100 watt all solid-state 2 stage power amplifier. A 2 watt 2 stage preamplifier and power switch. A BPSK 4 KB/sec transceiver containing a BPSK receiver, vector phase modulator (+13Dbm output) and three frequency synthesizers. A low-power microprocessor controller used to perform radio control and link and network protocol functions. This assembly also contains a digital signal processor (DSP)and digital to analog converter (DAC)for generating the in-phase (I) and quadrature-phase

(Q) base band signals required to generate the BPSK RF signal. An 8 channel GPS receiver (optional) The following paragraphs contain a brief description of each of the five main hardware elements in the 545C. Figure 2.2 presents a block diagram for the 545C.

There are a number of factors to consider in selecting an optimum site:

1. 2. 3. 4. 5. External Noise/Interference Horizon angle DC power source Site dimensions Antenna considerations These factors are particularly important for meteor burst operation, however, many are applicable for ELOS operation as well. 3.1.1 External Noise/Interference Noise and signal interference can reduce the performance of the MCC-545C. The most common sources of noise and interference are as follows:

! Cosmic Noise

! Power Line Noise

! Automobile Ignition Noise

! Computer-Generated Interference

! External Signal Interference Cosmic Noise Cosmic noise is the limiting noise factor in a meteor burst system. This noise is generated by star systems in the galaxy and is frequency dependent. The noise is approximately 15 db above thermal at 40 MHz and 13 db above thermal at 50 MHz. The noise is also diurnal in nature. It is the highest when the antennas are pointed directly at the center of the galaxy and lowest when they are pointed at right angles to it. Daily variations of 3 to 4 db can be expected. An optimal meteor burst site is one that is limited only by cosmic noise. The MCC-545C STAT command is very useful in determining the site antenna noise levels. The STAT reading should be between 120 and 115 dbm for an antenna line loss of about 1 to 2 db

(100-200 ft of RG-214). The noise blanker is not effective for eliminating cosmic noise, therefore the noise readings will be the same whether the blanker is on or off. MCC-545C PACKET DATA RADIO 12/2000 DESCRIPTION 2-19 Power Line Noise One of the main sources of external noise are high voltage power lines. Noise on these lines is generated by high voltage breakdown occurring on power line hardware such as transformers and insulators. This noise can be seen with an oscilloscope at the Receiver IF test point as a series of spikes that occur every 8 ms (1/60 Hz) or every 10 ms (1/50 Hz). The level of the spikes will be much higher than the normal background noise floor. The number of spikes can vary, depending upon the level of interference, from one or two every 8-10 ms to several dozen every 8-10 ms. The impulse noise blanker can remove a large amount of this noise. However, as the number of spikes increase, the effectiveness of the blanker is reduced. When setting up a site always look at the IF test point with a scope to determine the level of the power line noise interference. It is mandatory that power line noise be avoided for an optimum site. Try to set up the receiver antennas well away from power lines and do not point the antennas directly toward nearby power lines. Power companies are required to properly maintain their power lines to reduce noise. Call your local utility in case of severe noise. NOTE. Automobile Ignition Noise Automobile ignition noise is generated by all gasoline engines and is a result of the high voltage required to fire the spark plugs. Auto ignition noise is similar to power line noise with the exception that it does not have the 8-10 ms period which is associated with power line noise. If the MCC-545C is operated on a vehicle, care must be taken to ensure that the vehicle ignition system, DC motors, or any other source of electrical noise is isolated through shielding, ferrite bead, and/or bypass capacitors. Computer-Generated Interference All computers and printers contain high-speed circuits that generate spurious signals throughout the 37-50 MHz band. Interference will result if any of these signals couple into the antenna at the MCC-545C receive frequency. To avoid this type of interference, keep the antenna away from buildings that contain computers. Separating the antennas from the computers by 100 to 300 feet will generally prevent this type of interference. The noise blanker will not suppress computer-generated interference. Signal Interference This type of interference will occur whenever another transmitter is operating on the receiver center frequency of the MCC-545C. Antenna nulling and spatial separation can be used to reduce this type on interference. MCC-545C PACKET DATA RADIO 12/2000 DESCRIPTION 2-20 3.1.2 Horizon Angle The second consideration in site selection is the horizon angle in the direction of the Master Station. To achieve optimum performance at ranges up to 1600 km (1000 miles) the horizon, or look angle, must be within 2 or 3 degrees of horizontal and must be free from obstructions, buildings, bridges, etc. Trees and shrubbery do not present a problem if they are at least 20 feet from any element of the antenna. At shorter ranges the horizon angle must be higher. 3.1.3 Power Source The MCC-545C requires a 12 VDC power source. An automobile battery provides an excellent power source. Care must be taken to ensure that proper wire size is used to support the MCC-

545C high in-rush current during transmission. Typical transmit current is 25 to 30 amps for a time period of about .10 second. A #14 wire (or two #16 wires) should be used for both the +12 VDC and ground wires. The wire length should be shorter than 10 feet. The MCC-545C does not have an internal fuse and special care must be taken to protect the unit from a power line reversal. 3.1.4 Site Dimensions To obtain the maximum performance from a meteor burst site, the station must be set up on level, flat ground. The terrain in front of the antenna must be flat and free of buildings and other structures for a distance of at least 30 times the height of the antenna. Operation in an area that does not have a proper ground plane to provide ground reflection can reduce meteor burst performance by a factor of two. 3.1.5 Antenna Considerations The final consideration in setting up a site is selecting the antenna and the co-ax cable. The antenna must provide a 50 ohm load and this impedance must be maintained at both the Tx and Rx frequency. The information bandwidth of the system is less than 15 KHz. Therefore, in a single frequency system, a very narrow bandwidth antenna can be used. The higher the antenna gain the better the performance will be. Yagi antennas will work better than dipole antennas (2 to 4 times improvement). Always maintain the same antenna polarization at the remote station as the Master Station antenna. For example, if a whip antenna is used at the MCC-545C, the Master Station antenna must also be vertically polarized. In a Meteor Burst System, the height of the antenna should be optimized as a function of the distance between the Master Station and the Remote Station. A plot of antenna height vs. range is given in Figure 3.1 below. MCC-545C PACKET DATA RADIO 12/2000 i

A NEMA waterproof enclosure is therefore recommended for outdoor installation when an environmentally controlled shelter is not available. To ensure proper operation, shielded cable is recommended for all connectors. Also, use adequate strain relief on all cables and a weatherproof seal at the entry point of the enclosure. 3.2.1 Antenna Installation Antenna installation is very dependent on the site conditions and proper antenna placement can make the difference between a system that works very well or one that works marginally. Always consult with MCCs engineering department for assistance if any questions arise with respect to proper placement of the antennas. Assembly instructions are included with each antenna. Please refer to these for proper assembly of all antenna elements. 3.2.2 Cable Connections There are a maximum of four cable connections to be made to the MCC-545C as shown below:

I/O DC GPS Antenna

(Optional) VHF MCC-545C PACKET DATA RADIO 12/2000 DESCRIPTION 2-23 3.2.2.1 DC Power The MCC-545C requires a power source that can deliver up to 25 amps of pulsed power (100 msec) out of a +12 VDC to +14VDC power source. The 25 amp power demand will cause a voltage drop to occur at the transmitter input, resulting in reduced transmit power, unless the power cable to the source is sized appropriately. MCC recommends using two #16 AWG wires for both the power and ground and a cable length that does not exceed 10 feet. If a longer cable is required use #14 AWG. MCC provides a standard 6 foot power cable with lugs for connecting to a 3/8 battery post (Part No. 14001261-03). The power connector pins are as follows:

The voltage drop at pins 1 and 2 should not drop by more than 2VDC during transmission. 3.2.2.2 VHF Antenna Connect the antenna cable to the BNC RF connector. RG-223 may be used for cable lengths under 20 feet. Use a double shielded cable (RG-214) for cable lengths up to 100 feet. 3.2.2.3 GPS Antenna (Optional) An external GPS antenna is required if a GPS receiver is installed in the MCC-545C. Connect the GPS antenna cable to the SMA connector on the front panel. 3.2.2.4 I/O Port The 44 pin I/O connector on the front panel includes three RS-232 ports as one Data I/O port. MCC provides a standard cable harness that breaks out these four ports as shown below:

Refer to Section 3.2.2 for complete cabling instructions. IMPORTANT 3.3.1 Power On Disconnect the antenna cable until the unit ID has been set (see paragraph 3.3.2). CAUTION To power up the MCC-545C, apply +12VDC to the power connector. When the unit transmits it will draw up to 25 amps, therefore, review section 3.2.2.1 for cabling to the power source. The voltage drop at the input connector during transmission should be less than 2 VDC for proper operation of the unit. NOTE The following message should appear on the operator terminal when power is applied:

12/23/00 16:54:10 POWER SHUTDOWN/FAIL OCCURRED. 01/02/01 12:54:44 POWER HAS BEEN RESTORED... RESUMING OPERATION.

If this message does not appear then the baud rate may not be set correctly in the operator terminal. The default baud rate setting in the MCC-545C is 9,600 baud, 8 data bits, one stop bit and no parity. This baud rate setting may be changed in the MCC-545C using the SETBAUD and SAVE commands, as described in Chapter 4. The default baud rate settings are stored in flash memory. However, it is possible to lose these settings if the lithium battery has lost its charge after the MCC-545C has been sitting on the shelf for an extended time period. In that event, a message similar to that shown below will appear upon start-up. METEOR BURST RADIO SUBSYSTEM MBCT

(c) Copyright 2000 Meteor Communications Corp. All Rights Reserved RF Modem S/W Part Number P1060-00-00 Version 6.25 12/19/00 The desired baud rate must then be entered using the SETBAUD and SAVE commands. MCC-545C PACKET DATA RADIO 12/2000 DESCRIPTION 2-29 3.3.2 Entering the Unit ID It is very important that the unit ID is entered correctly before transmitting. If the unit transmits with the wrong ID it may conflict with another unit in the system and will result in data or messages being misrouted or lost. In addition, the network topography and statistics will receive incorrect data that will impair network performance. Use the ID Command to set the unit ID:

ID,nnnnn,mmmm{,aaaaa},INIT where nnnnn is the unit ID, mmmm is the Master Station assignment and aaaaa is the initial Master Station connectivity setting. Obtain these numbers from your network manager. The MCC-545C will save the ID and reboot whenever the unit is powered up or reset. 3.3.3 Set and Verify the Tx/Rx Frequencies The MCC-545A is programmed by a factory-trained technician to operate on a number of authorized frequency channels. Once programmed, these frequencies can be selected by the operator from a keyboard. You can set or display the TX and RX frequencies using the following command:

FREQUENCIES, XXXX,YYYY Where XXXX is the desired transmit frequency and YYYY is the desired receive frequency Example: FREQUENCIES,4550,4550 This will select 45.50 MHz for both the transmit and receive frequency. Only those frequencies that have been previously programmed into the unit at the factory can be selected. Once the frequencies are selected, confirm that the synthesizer is ON and locked by entering the following command:

SYNTHESIZER, ON The unit will respond with SYNTHESIZER, ON Locked or Unlocked If the synthesizer returns an unlocked response, check the frequency command to ensure that the proper frequencies have been entered. The MCC-545C will not transmit if the synthesizer is not locked. NOTE MCC-545C PACKET DATA RADIO 12/2000 DESCRIPTION 2-30 3.3.4 RF Test A very thorough RF test can be made by typing TEST[CR]. TEST causes the processor to turn the transmitter ON and measures the forward and reverse RF power that is being transmitted. It also measures the battery voltage under load and the antenna noise voltage. The following response will be displayed on the operator terminal:

Syncs Xmits Acks pwr-fwd pwr-rev v-bat det-RF XXXX YYYY ZZZZ AAAA BBBB CCC DDD where: XXXX YYYY ZZZZ AAAA BBBB = Reflected power in watts. This should be less than 5 watts. CCC

= # of sync patterns received from the master station.

= # of transmissions made by the MCC-545C.

= # of Acknowledgements received from master station.

= Forward power in watts. This should be greater than 80 watts.

= Battery voltage under load (while transmitting). This should be greater DDD

= Received signal strength in dbm. This will normally be the noise level than 10.6 VDC. at the antenna. Troubleshooting Suggestions If the battery voltage is normal, the forward RF power should be at least 80 watts. If it is lower than 80 watts check for proper cabling to the power source. (see Section 3.2.2.1). If the reverse RF power is greater than 5 watts check the antenna and coaxial cabling for proper installation. If both the forward and reverse power are low, the transmitter may be automatically shutting down due to an antenna VSWR greater than 3:1. Check the antenna and coaxial cabling for proper installation. This completes the power-up sequence of the MCC-545C. The unit is now ready for operation. Refer to Chapter 4 for detailed operating instructions. MCC-545C PACKET DATA RADIO 12/2000 DESCRIPTION 2-31 MCC-545C PACKET DATA RADIO 12/2000 4.0 OPERATIONS This chapter covers the fundamental operating procedures of the MCC-545C and is functionally divided into seven sections:

OPERATIONS 4-1

! Getting Started

! Station Operational Parameters

! Sending and Receiving Messages

! Data Logging

! Reporting Position Location

! Master Mode Functions

! Examining System Statistics 4.1 Getting Started 4.1.1 Command Entry and Editing You must enter carriage returns after every command. A list of all the operator commands are given in Table 4.2. When a command is accepted, the operator terminal will print the system time. For a description of printouts, see Appendix A. Before you begin you should familiarize yourself with the special editing functions that you can use when entering commands:

[DEL] Deletes last character entered.

[CTRL] Prints command line on next line down.

[CTRL]-R Repeats last command line

\X Removes current line from command buffer.

[CR], [LF] or [ENTER] Terminates line and causes the command entered to be executed. 4.1.2 Unit Name and Station ID In command descriptions, the parameter "name" is the assigned Station name. The name is the numeric Station ID. For more information on MCC-545C operation as either a Remote or Master Station, refer to Section 4.2.1. Station IDs, represented by "nnnn", can be assigned as follows:

1 245 256 4095 Master Station Remote MCC-545C PACKET DATA RADIO 12/2000 OPERATIONS 4-2 Verify the ID is set correctly with the following command:

ID If it is not correct, refer to section 3.3 for procedures to set it. 4.1.3 HELP Command Information about many of the MCC-545C commands can be obtained via the HELP command. Typing HELP with no parenthesis produces a single page display of the alphabetized command list. Typing HELP,command provides a summary explanation of how to use that particular command. For example, typing HELP,ASSIGN explains the format to use when you enter the ASSIGN command, along with a brief description of the command's function. 4.1.4 System Time and Date The system calendar is maintained during power outages. If the date and/or time shown is incorrect the calendar can be initialized with the following commands:

DATE,mm/dd/yy TIME,hh:mm{:ss}

The time of day maintained in the MCC-545C is transmitted to all Remote Stations keeping all units in a network on the same time reference. If the time of day received at a Remote Station differs by more than two minutes from the internal Remote clock, the Remote will set its clock to the received time of day. To properly manage time, each Master Station and Remote Station must know how its own time zone relates to UTC and the system time. This relationship is established by relating its time zone to known reference points. UTC is always referenced to GMT; however, system time can be referenced to any desired time zone. The time zone offset is defined with the following command:

TIME ZONE,UTC offset,system offset 4.2 Station Operational Parameters In order for the MCC-545C to operate correctly in your network, it must be properly configured. Configuration requirements will vary from application to application, therefore refer to your systems manual or consult your systems manager for correct settings. Use the commands described in this section to set the configuration as required. You may use the CONFIG and ASSIGN commands to verify proper configurations have been set. MCC-545C PACKET DATA RADIO 12/2000 Finally, enter the SAVE command to write the configuration into the EEPROM for non-volatile storage. OPERATIONS 4-3 4.2.1 Configuring the MCC-545C Configuration parameters include the unit ID, the Master Station assignment, I/O port functions and baud rates, transmit and receive parameters and network parameters. Commands which allow you to display/modify the configuration are marked with an * in the command table. Parameters or operational states set by these commands are retained and will determine the way in which the MCC-545C will interact with other equipment at the site and with the communications network. Most configuration parameters can be viewed with the "CONFIG" and the "ASSIGN"

commands. You should use these commands to verify that the configuration is correct. If it is not correct, use the appropriate command(s) to correct the configuration, then enter the "save"

command to write the configuration parameters into the EEPROM. Saving and Restoring the Configuration - The Theory To aid your understanding how the MCC-545C operational configuration is saved and restored it is helpful to understand the hardware and design philosophy of the MCC-545C. The MCC-545C is designed to operate unattended in a variety of environments where power may be applied continuously or intermittently. The goal is for the unit to continue to operate without loss of messages, data or configuration even if power is randomly turned on and off. Therefore the software is designed to operate continuously, to save all operational information when power is off and to resume operation from that point when power is restored. To support this philosophy, the MCC-545C has three types of memory: PROM, RAM and EEPROM. The PROM is non-volatile memory that has been programmed with the MCC-545C's operational software. This software contains the initial values of all operational parameters. The values are referred to as the "factory defaults" because they are programmed in the factory when the unit is first manufactured. The PROM can only be modified by replacing this chip with one programmed with the new data. The RAM contains all the dynamic data for the MCC-545C. All data logger data, positional data, and messages entered into the MCC-545C are stored in RAM. Also, all command parameters are stored in RAM. But RAM is volatile and can only retain information while power is applied. Turning off or disconnecting power will cause all RAM information to be lost. To prevent this, a small internal NiCad battery is used to maintain power to the RAM when external power is off. During normal operation, the MCC-545C software operates from the data and the parameters that are stored in RAM. Unfortunately, there are always situations when the RAM data may be lost or corrupted due to total discharge of the battery, software crash or operator error. Since we do not want to lose our configuration data during these situations, we have a third type of memory. MCC-545C PACKET DATA RADIO 12/2000 OPERATIONS 4-4 The third type of memory is EEPROM. It is nonvolatile and retains data even when power is removed. Special access is required to program the EEPROM therefore it is not easily corrupted. The MCC-545C can retain a copy of all the programmed configuration parameters in EEPROM. However, EEPROM is limited to 10,000 write cycles per memory location so the MCC-545C only writes to EEPROM using two special commands - "ID" and "SAVE". Only values that have changed are written into EEPROM. A validation checksum is saved in the MCC-545C to verify its data is correct. When the MCC-545C ships from the factory it programmed with the following default configuration: the Operator Port (port 0) is set for 9600 baud, 8 data bits, 1 stop bit, no parity, ASCII protocol and no flow control. This provides a known starting point for communicating to the unit from a terminal or computer. From this starting point, the user can program the unit ID and other operational parameters and then use the "Save" command to write them to EEPROM. As soon as the parameters are entered they take effect. Once the software is rebooted or restart due to a crash or failure of the battery backup RAM, all changes will be lost unless they were previously saved in EEPROM. CAUTION Saving and Restoring the Configuration - The Operation 1. The software normally executes using the data and parameters stored in RAM. When the unit is turned off, or power is disconnected, the RAM information will be maintained by battery backup. When main power is restored the unit continues operation from RAM. 2. The RAM contents will be lost under the following conditions:

(1) if the Reboot command is issued

(2) the white Reset button (S1) is pressed

(3) the internal battery backup is disconnected (by removing jumper JP1 while external power is off)

(4) the NiCad battery fails or

(5) the software crashes and restarts. The software will detect these events and will then recopy the configuration values from EEPROM back into RAM when operation is resumed. 3. The software will revert to the factory settings contained in the PROM if the contents of the EEPROM become invalid. The user should beware that it is possible to "get in trouble" using the configuration process. For example, assume you accidentally set the protocol for the operator port to MSC. If you do not have the ability to interface using MSC protocol you will immediately lose contact with the MCC-545C PACKET DATA RADIO 12/2000 MCC-545C. You will no longer be able to issue commands. Power cycling will not help either because your change will be retained in RAM, even through power cycling. However, you can always recover by removing the lid on the MCC-545C and pressing the Reset button (S1). This will reboot and restore the EEPROM settings. OPERATIONS 4-5 Alternatively, assume you want to change the operator port to MSC. You connect in ASCII protocol, command the change to MSC protocol, then switch you PC to also use MSC protocol. Operation resumes and all is well. But do not forget to do a SAVE. If the software ever reboots, it will revert back to ASCII. And remember, once you do the SAVE you are committed to MSC protocol. The Reset button now reboots to MSC and there is no easy way back to the factory default settings. You will need an MSC capability to command a change back to ASCII. 4.2.2 Selecting MCC-545C Remote/Master Operation The MCC-545C can operate as either a Remote Station or as a Master Station. Use the DEVICE command to select the mode you require. For normal MCC-545C Remote Station operation, enter:

DEVICE,REMOTE For MCC-545C operation as a Master Station, enter:

DEVICE,MASTER Additional MCC-545C commands are available when DEVICE,MASTER is selected. There is no help for this command. NOTE 4.2.3 Selecting Network Parameters MCC recommends using the given default network parameters (values that are set on power-up or after reset). If you choose to change these parameters, first review the discussion in this Section and in Section 4.8.5, then use the following commands to change to the desired settings:

SNP{,pname,value}

where "pname" is the network parameter and "value" is a limit dependent on "pname". The

"pname" parameters are as follows:

TTL Time-to-live in minutes (default is 120 minutes); this is the time limit for a message to reach its destination before it is deleted from the queue. The time-to-live parameter input is truncated to a 10-minute boundary. If you enter 60 through 69, the TTL for the next message will be 60 minutes. A resultant value of 0 (parameter range 0 9) means the message will never time out. MCC-545C PACKET DATA RADIO 12/2000 OPERATIONS 4-6 TTR NUP Time-to-retransmit in minutes (default is 20 minutes); i.e., the message is retransmitted if it has not reached its destination within this time frame. Neighbor-up threshold (default is 20 acquisitions); the number of times a Station must hear from another Station within a one minute time interval before it becomes a neighbor. NDOWN Neighbor-down threshold in minutes (default is 20 minutes); if there is no communication with a neighboring Station within the set time, the route to that neighbor is ignored. Setting NDOWN to 0 maintains the routing to the neighbor indefinitely. RDOWN MASTER OPERATION ONLY - Remote-down threshold in minutes (default is 1,440 minutes); if there is no communication with a Remote Station within the set time, the Remote is declared down and is removed from the Remote table. Setting RDOWN to 0 keeps a Remote defined indefinitely. OTL Outstanding text limit (default is 20 texts); the number of messages a Station is allowed to send to another Station without an end-to-end acknowledgment. CONNP MASTER OPERATION ONLY - Connectivity message precedence (default is 1 precedence); information on changes in the connectivity table is given highest precedence (automatic feature). ETEAP End-to-end ACK message precedence (default is 0 [zero] precedence); the acknowledgment of a message when it reaches its final destination is given highest precedence. HTO History file timeout in minutes (default is 10 minutes); maintains information for duplicate filtering. TEXTL MASTER OPERATION ONLY - Text size in segments (default is 32 segments). FLOODP MASTER OPERATION ONLY - Partial "flooding" precedence level (default is A precedence). Messages of this precedence level and above are transmitted over all routes of minimum length; messages below this precedence are not sent over all minimum length routes, but are sent only over the routes where the shortest transmit queues exist. MBHOP meteor burst link hop weight (default is 1 hop). Defines the number of network hops to associate with a meteor burst Master Station link when determining the minimum path to use in routing a message. MBHOP should be set high enough to prevent a meteor burst Master Station link to be chosen over a line-of-sight Remote to Remote link in a network that is predominantly line-of-sight. INF MASTER OPERATION ONLY - Infinity hop quantity (default is 8 hops). Defines the width of the network in hops plus one to determine when connectivity MCC-545C PACKET DATA RADIO 12/2000 to a node is broken. Should be as low as possible to minimize auto-connectivity traffic in the network, but large enough to not erroneously flag nodes as being offline. OPERATIONS 4-7 RELAY MASTER OPERATION ONLY - Relay function specification (default is ON). Specifies whether the MCC-545C should act like a Remote in terms of relay functionality (i.e., does not share connectivity table with other Masters. DATAP priority of data reports initiated at the MCC-545C (default is Y precedence). When used in any data collection network, this setting defines the precedence of data reports generated asynchronously by the equipment itself. Typically, it should be lower than operator entered messages and commands. 4.2.4 Selecting the Burst Monitor The MCC-545C has a unique meteor burst monitoring capability that allows monitoring the number of characters received, the RF signal level and other parameters on each reception. To turn on the burst monitor and to record statistics on a meteor burst link, type:

MON{,d{,r}}

The two optional parameters are designed to limit the printout. The burst monitor generates two or three lines of printout for every burst. This could conceivably create hundreds of pages of printout a day in a network environment. The first parameter is the duration character count limit. Only meteors lasting long enough to deliver "d" characters will be monitored. The second parameter is the received character count limit; if at least "r" characters are received on the burst, a monitor line will be generated. The default values are 100 for "d" and 1 for "r". For example, to limit the printout, but still receive some maintenance benefit from the monitor, enter:

MON,500,100 This will limit the printout to meteors that have a duration character count greater than 500, or a received character count greater than 100. These parameters may be adjusted as desired. The command MONOFF turns off the burst monitor. 4.2.5 Controlling the Hourly Statistics Report By default, an hourly statistics report is generated on the maintenance terminal port on the hour. This report consists of the same statistic reports generated by the BINS, MEM, and STAT commands. The hourly report can be disabled by entering the command:

HOURLIES,OFF MCC-545C PACKET DATA RADIO 12/2000 OPERATIONS 4-8 The hourly report can be re-enabled by entering the command:

HOURLIES,ON 4.2.6 Scheduling MCC-545C Events The SCHED command allows you to schedule automated command "events". An "event" simply consists of giving one or more commands a trigger time. When the MCC-545C's real-time clock reaches the trigger time, the scheduler invokes the command as though you had entered it from the MCC-545C's operator terminal. Two different types of time trigger options are provided for command scheduling: INTERVAL and TIME. The INTERVAL trigger allows you to schedule a command to be invoked at periodic intervals within a 24-hour time period; the TIME trigger allows you to schedule a command to be invoked only once at a specified point within a 24 hour time period. The command schedule list is restarted each time the real-time clock reaches midnight. To display the current schedule list, enter:

SCHED To add a new command to the schedule list, enter:

SCHED,type,time{OFFSET,time},command where: type = INTERVAL or TIME time = hours:minutes:seconds OFFSET,hh:mm:ss = time offset from specified timeframe (optional) command = any MCC-545C command (with parameters) The scheduler ignores certain commands due to their interactive nature. The MESSAGE command is currently the only one ignored NOTE To remove command event(s) from the schedule list, enter:

SCHED,DEL,xxx where: xxx = ALL (erases entire schedule) or

= schedule list number (removes single scheduled event from the schedule list) MCC-545C PACKET DATA RADIO 12/2000 The MCC-545C currently supports up to 50 scheduled command events. The schedule list will be erased if the system software re-boots (not to be confused with power failure recovery, which will preserve the schedule list). IMPORTANT OPERATIONS 4-9 You can schedule several command events to trigger at the same time, however, you cannot force one command to execute before or after another. After assigning command events to the schedule, the order of commands displayed in the schedule list is the order in which the events will trigger for any given trigger time (i.e., an event with a low schedule number occurs before an event with a higher schedule number). 4.2.7 Setting Timeout Duration There is one programmable time limit for the I/O port input on the MCC-545C. MCC recommends using the pre-programmed default timeout parameter. If you choose to change the timeout the time limits may be set by entering the number of seconds, from 0 to 32767. Enter a 0 to turn off the time limit. Command Description STT,secs The Set Teleprinter Timeout command sets the time limit for characters at the maintenance terminal. Default is 60 seconds (1 minute). 4.2.8 Setting Frequencies The FREQUENCIES command is used in systems using synthesized frequencies only (see Section 2.7.4). To enable setting frequencies, you must first enter the following command to identify the system as a frequency synthesized system:

SYNTH,ON You can then display/set the TX and RX frequencies using the following command:

FREQ{UENCIES{,aaaa,bbbb}}

where: aaaa = Tx Frequency (e.g., 4053 for 40.53 MHz) bbbb = Rx Frequency (e.g., 4153 for 41.53 MHz) MCC-545C PACKET DATA RADIO 12/2000 OPERATIONS 4-10 The MCC-545C limits the usable frequency range to a 2 MHz bandwidth. If frequencies are to be changed outside this bandwidth then hardware modifications must also be made to the MCC-

545C. IMPORTANT If the synthesizer is unable to establish phase-lock when the SYNTH,ON command is entered, the MCC-545C will respond UNLOCKED to the request and turn off the TX key. It will try once a minute thereafter to establish phase-lock. If it fails, the message Synthesizer unlocked will be displayed; if it succeeds, the MCC-545C will respond LOCKED and turn on the TX key. 4.2.9 Defining Data Relays The ambient noise conditions at a remote station site may sometimes be excessive and a poor communication path to the Master Station will result particularly if the remote station is operating in a meteor burst mode. To overcome this problem, another MCC-545C may be placed in a nearby quiet location and used as relay station between the MCC-545C at the noisy site and its master station. When used as a relay, the MCC-545C will concentrate the data reports it receives from one or more neighboring remote sites and forwards the data to the Master Station. When used in the relay mode,, the MCC-545C must be defined as a Master Station. The relay will then receive MCC-550C sensor data GROUP reports (see MCC-550C Operations Manual), repackage them and forward them to the Master Station. A relay can handle a total of sixteen GROUP reports. These reports can be in any combination; i.e., four groups from each of four Remote units, one group from each of sixteen Remote units or any combination in between. Substitution tables must be established in both the relay unit and also at the Master Station to manage the relay function. When a designated GROUP report is received at the relay, it will substitute its own ID and group number in the report as defined in its substitution table and forward the data to a MCC-520B Master Station using the MCC-550C RF format rather than the standard MCC-545C message format. When the relayed data is received at the MCC-520B it reconstructs the original data report based on its own substitution table and route the report as required. The following command is used to define the entries in the substitution table for a relay unit:

SUBST,relay_id,relay_group,remote_id,remote_group where: relay_id is the relay unit's ID is the data group report number at the relay is the originating Remote unit's ID relay_group remote_id remote_group is the data group report number at the originating Remote unit MCC-545C PACKET DATA RADIO 12/2000 4.2.10 Scaling A/D Readings OPERATIONS 4-11 The MCC-545C automatically scales the readings from its A/D converter for operator use. The readings that require scaling are battery level, detected RF and transmit power. The scaling factors that are required for these readings will depend on the type of hardware used at the MCC-

545C site and are set by operator command using the SCALE command. The SCALE commands are summarized in Table 4.1. There are four values that need to be scaled depending on the equipment configuration at the site:

! Battery Voltage (used by the STAT/TEST commands)

! Detected RF in db (used by the MM command, meteor monitor and BINS command)

! Detected RF in microvolts (used by the STAT/TEST commands)

! Transmit power level (used by the STAT/TEST commands) The required scaling factors are determined by the power supply used in the packet data radio. The RXTYPE command translates the receiver calibration curves from detected RF (in db) to microvolts. These are nonlinear and significantly different for the MCC-527 and MCC-543 receivers.. To apply the scaling factors, the TXPWR A/D value must first be squared and then multiplied by the scaling factor in the table. For the other values, use the A/D reading directly and multiply by the appropriate scaling factor. MCC-545C SCALING FACTORS PARAMETER BAT DETRF TXPWR RXTYPE 12V 0.0623 0.0188 0.000353 527 36V 0.05 0.1074 0.00116 543 28V 0.1749 0.0188 0.000353 527 TABLE 4.1 4.3 Sending and Receiving Messages The MCC-545C is a packet data radio and therefore enables an operator to send and receive messages to all nodes within the network. The messages may be entered from an operator terminal that is connected to the OPERATOR PORT of the MCC-545C. There are three basic message types: (1) free-form text messages, (2) canned messages and (3) commands. The general format for all messages is shown below:

MESSAGE, R , dest 1, dest 2, dest n where: R = Message priority; A is highest, Z is lowest. dest = ID of the station(s) to which the message will be sent. MCC-545C PACKET DATA RADIO 12/2000 Messages are first entered and edited in the TEXT EDIT BUFFER. They are then transferred to one or more TX QUEUE buffers for transmission to the designated destinations. The diagram below depicts the general flow of messages within the MCC-545C software and the various commands associated with each step in the process. OPERATIONS 4-12

Messages may be 3,570 characters in length. When composing the message press [CR] at the end of each 80 character line. MCC-545C PACKET DATA RADIO 12/2000 There is a default destination programmed into the MCC-545C during the installation and initialization of the unit when it is first brought on-line in the network. If a message is not given a specific destination it will be sent to the default destination only. OPERATIONS 4-13 To enter a message:

1. 2. 3. Type MESSAGE. The operator terminal will respond with ENTER TEXT. The MCC-

545C will now be in the compose and edit mode. Enter a message up to 3,570 characters in length, pressing [CR] at the end of each 80 character line. Press the [ESC] key. The message will now be transferred to a Tx queue and will be automatically transmitted to the default destination at a priority level R. The following message will be displayed, or printed, on the operator terminal:

hh:mm:ss Message No: name:ss,nnnn chars, nnn segments hh:mm:ss ROUTING name :sss TXT sss/nn TO: name If you wish to send a message to multiple destinations, and at a different priority level, type MESSAGE, R, dest1, dest2, dest n where: R is any priority level from A to Z. A is the highest and Z is the lowest. Dest is the numerical ID of the stations to which the message will be routed. If you also want to send the message to your default destination you must enter its station numerical ID as one of the destination parameters (dest1, dest2, etc.) as specified above. NOTE If you want to use source routing enter 0 for the destination ID. When the master station receives this message it will send the message to the appropriate destination based on its link table showing which destination(s) are linked with your station. Refer to the master station manual for more information on source routing. NOTE There are three other special editing functions that may be used:

1. To Retransmit A Previously Entered Message To retransmit a previously entered message simply depress the [ESC] key after the operator terminal prints ENTER TEXT and before any other key is depressed. The previous message entered into the TEXT EDIT BUFFER will then be sent to the destinations that are now designated in the MESSAGE command. MCC-545C PACKET DATA RADIO 12/2000 2. To Revise A Previously Entered Message OPERATIONS 4-14 To revise a previously entered message press [CTRL]T after the ENTER TEXT prompt to revise a previously entered message or to recover from an aborted session. The previous message will be displayed with the cursor placed at the end of the message. You may now resume editing the message. 3. To Delete a Message To delete a message after it has been placed in the Tx Queue, type DELMSG, ID: sss where: ID is the numerical station ID sss is the message serial number The operator terminal will print the date and time, followed by MESSAGE DELETED. 4.3.2 Editing Messages The following editing functions may be used while the message is in the TEXT EDIT BUFFER. KEY

[CTRK]A ESC FUNCTION Deletes the last character entered. Prints the current line of text on the next line down. Performs a fixed tab function Removes the current line from the edit buffer. Performs a carriage return and line feed. Performs a carriage return and line feed. Removes the current line from the edit buffer and places the cursor at the end of the previous line. Prints the contents of the edit buffer. Erases the entire contents of the edit buffer. Aborts the edit mode and returns to the command mode. A + indicates the command mode. Leaves text edit mode and queues the message for transmission. 4.3.3 Sending Messages Messages are automatically transmitted with the [ESC] command. Each message will be placed in the Tx Queue in accordance with its assigned priority. Messages of equal priority are placed in the Tx Queue in the order received from the TEXT EDIT BUFFER. The following display will appear on the operator terminal as the MCC-545C begins to transmit a message:

MCC-545C PACKET DATA RADIO 12/2000 hh:mm:ss Message No: name:ss,nnnn chars, nnn segments hh:mm:ss ROUTING name :sss TXT sss/nn TO: name OPERATIONS 4-15 Messages are transmitted in packets and are routed to their destination in a store and forward manner, using the most efficient routing within the packet switched network. The originating station will receive an acknowledgement (ACK) if the message has been received successfully by the first routing station. mm/dd/yy hh:mm:ss TXTMSG ACK name:sss, xxxx CHARS FROM name When the entire message has been delivered to its final destination an end-to-end acknowledgement will be displayed on the operator terminal:

hh:mm:ss END-TO-END ACK OF name:sss FROM name If the end-to-end ACK is not received within the specified time-to-live limit, the MCC-545C will purge the message from the Tx Queue and display the following message:

hh:mm:ss MESSAGE TIME-TO-LIVE EXPIRED, MSG.NO:sss, DESTN: name You must then reenter the message. Continued failure to successfully transmit a message indicates that something may be wrong with the equipment or the link (e.g., excessive noise interference). 4.3.4 Sending Commands Commands may be sent to any remote station within the network. The entry of a command is similar to the MESSAGE command described in Section 4.3.1. REMCMD, R, dest1, dest2, destn where: R dest

priority level numerical ID of destination station(s) The operator is then prompted to enter the text of the command using the message editor. Once the command is entered, press the [ESC] key to send the command. The operator terminal will display:

hh:mm:ss Message No: name:sss, nnnn chars, nnn Destination ID Message Number (0-

Number of 14-character Number of A response will be received from the destination station(s) if it was successfully received. MCC-545C PACKET DATA RADIO 12/2000 4.3.5 Sending Canned Messages OPERATIONS 4-16 The MCC-545C may be placed into a canned message mode for automatic transmission of a repetitive message to an assigned neighboring station. In the canned message mode no more than 25 messages may be placed into the Tx Queue at one time. You may either send an edited text message or a message that is randomly generated from the alphabet. To enter a canned message generated from the alphabet, enter:

CANMSG,id,msg length{,min.queue depth}

where id is the neighboring station ID, the message length is from 1 to 3000 characters and the queue depth is from 1 to 25. The default queue depth is 5. Additional canned messages will be injected if the number of canned messages in the queue falls below the minimum queue depth. To enter an edited canned message, enter:

CANMSG,id where id is the neighboring stations ID. After composing your message press the [ESC] key. The MCC-545C will automatically route up to 25 copies of the canned message to the destination station. Each canned message will be acknowledged by the selected neighboring station. No end-to-end acknowledgement will be received. To terminate the mode, enter:

CANMSG OFF,id Canned messages are normally not printed at destination station. To print canned messages as they are received, enter:

CANMSG MODE,PRINT To turn off the print mode, enter:

CANMSG MODE,NO PRINT 4.3.6 Receiving Messages When a new message is received it is announced by the following display:

hh:mm:ss RECEIVING name:sss TXT sss/nn FROM name ROUTED TO: name The MCC-545C then generates an ACK of the message packet and transmits the ACK to the neighbor from whom the message was received:

MCC-545C PACKET DATA RADIO 12/2000 hh:mm:ss TXTMSG ACK name:sss, nnnn CHARS FROM name When the destination MCC-545C receives a complete message, it displays the following message:

OPERATIONS 4-17 hh:mm:ss MSG RECEIVED name:sss, xxxx CHARS text

**end-of-message**

where name:sss is the message serial number. Messages are deleted as they are displayed or printed unless they are being forwarded to further destinations. 4.3.7 Examining MESSAGE STATUS The status of all messages may be examined while they are still in the Tx Queue. (Note: once an ETE is received for a message it is deleted from the queue). To examine a message, enter:

SMS {,ID}

4.3.8 Examining and Revising Message Queues There are two types of queues for transmitting and receiving messages:

QUEUE NAME DESCRIPTION TXQ

(Transmit Queue) RXQ

(Receive Queue) This queue is used for transmitting all messages. There is a separate transmit queue for each neighboring station in the network. For example, if you enter a message for DEST1 That message is placed in DEST1s transmit queue. This queue is used for all received messages. There is a separate receive queue for each neighboring station in the network. For example, to examine message statistics from NODE5, examine the receive queue from NODE5. To examine the contents of either queue, type:

SHOW TXQ,ID or SHOW RXQ,ID You must specify the queue by entering the station ID. For example, SHOW TXQ,006 prints statistics for all messages being transmitted to station 006. MCC-545C PACKET DATA RADIO 12/2000 OPERATIONS 4-18 You can only examine the receive and transmit queues for neighbor stations in the network. To delete the contents of the transmit and receive queues, you must specify the exact queue by entering a station name:

FLUSH TXQ,id or FLUSH RXQ,id For each message deleted, the terminal prints:

Id:sss unlinked {and deleted}

The and deleted text appears only if the message is not present in another queue. When all messages have been deleted, the terminal prints:

queue flushed To delete a specific message, enter:

DEL MSG,id:sss The terminal prints:

Message deleted To delete all messages from all queues, enter:

FLUSH MSG For each message deleted, the terminal prints:

Id:sss deleted Entering the FLUSH MSG command deletes all messages in all queues for every node of the network, including connectivity and end-to-end acknowledgment messages.
