The manual is divided as follows:

Introduction, which gives some general information and document conventions. Using the addWAVE, which details the installation and use of the remote telemetry unit. Performing Advanced Functions, which discusses connectors and controllers and provides other information for advanced users. Specifications, which describes operating parameters for the devices. AbouttheA753addWAVESeries4 The A753 addWAVE Series 4 remote telemetry unit (RTU) is a low-

power telemetry device with four digital I/O ports, twelve analog inputs, and four counter inputs. The A753 is a ruggedized RTU, complying with the IP65 ingress protection class (NEMA 4). Depending on topography, it ensures a reliable wireless connection to other A73x RTUs or an A840/A850 Telemetry Gateway over a distance of up to 20km (12 miles). Due to its construction as well as to the software controlling it, the power consumption is extremely low. The unit operates off an internal 6.2 Volt rechargeable battery, which is charged either by a solar panel or an external power adapter. ComplianceStatementandWarnings The A73x must not be used with an antenna other than the one supplied by Adcon (or an antenna with identical technical specifications).

Chapter2.UsingtheaddWAVE CHAPTER2 7 Openingthepackages The A753 addWAVE remote telemetry unit (RTU) is part of the A7xx series. For testing purposes, you should have an A840 or A850 Telemetry Gateway with access to the internet installed before you install the A753 RTU. For information about installing the A840 or A850, refer to devices users guide. Openingthepackages The addWAVE RTU package contains the following items:

A753UHF Series 4 RTU (or A752 or A751) an antenna including a mounting bracket and a 3 m (9 ft.) cable three ring clamps (one for tightening the mounting bracket of the antenna) solar panel with ring clamp set of aluminum poles LED tool If ordered, the following items come in separate packaging:

Make sure you have received all the equipment and read through the instructions that follow. When you are sure you understand them, you are ready to install your RTU. CHAPTER2 8 InstallingtheRTU Figure 1 shows the front view of an addWAVE RTU. Figure 1. addWAVE RTU (A753) InstallingtheRTU In general, the typical line-of sight distance the RTU can communicate is 10km (6 miles). This is valid if both the RTU and its partner device are mounted on a 3 m mast (9ft.); the results may vary under different conditions, and you can sometimes achieve greater distances. As with all wireless communication devices, the higher the transmitter is installed, the better the communication will be. All A75x devices accept the standard Adcon sensors (A751 excluded). Installing a preset A753 in the field is a fairly simple process. By performing a connectivity check using an LED tool (not included in the delivery of a A753, but available from Adcon), you will be able to prove connectivity to your current radio network. FieldInstallation CHAPTER2 9 InstallingtheRTU The LED tool is shown in Figure 2. Figure 2. LED tool Note:

The LED tool is a blind plug to be connected to the SOLAR connector. Follow these steps to install an A753 in the field:

1. 2. 3. Review the installation area and choose the best site. Assemble the pole set. Put an Adcon plastic cap into the top of the pole and secure it with a pipe clamp to protect the top of the pole from damage. 4. Using a hammer, drive the 80 cm aluminum rod into the ground. 5. Using the pipe clamp supplied, fasten the solar panel onto the pole. Make sure that the panel is facing south (north if you are located in the southern hemisphere) and out of the way of the A753 RTU. Note:

The solar panel can be mounted under or behind the A75x RTU, but make sure that the RTU does not shadow the panel. 6. Fasten the A75x RTU to the top of the pole with a pipe clamp. Adcon recommends that you perform a connectivity test, if you can, to check the positioning of the device. WARNING If you turn the fastening screws too tightly, you could damage the connectors. 7. Attach the sensors to the I/O connectors and the solar panel to the POWER connector by turning the plugs fastening screws clockwise until secure. 8. If you have SDI-12 sensors, attach the respective sensors. This completes the installation of your A753. If the SOLAR CELL connector or the DC INPUT connector is left unused, use the cap provided to protect it against moisture and dust. Be sure to keep the following information in a place you can remember:

Serial number of the A753 (printed on the type plate) Location of the A753 Note:

This information will be necessary during the configuration of the device at the A850 Gateway. MoreabouttheLEDTool The LED tool allows you to rapidly check the status of an A753. See Table 1 on page 10 which describes the LED blinking codes for the A753. ConfiguringanA753intheTelemetryGateway CHAPTER2 10 A broadcast is sent to other stations when you plug in the LED tool. Wait approx. 30 seconds for completion of this broadcast, but look at the LED tool. If the A753 is heard by another RTU, it will receive an answer from that station. When the broadcast is completed, the LED tool will make a long flash to signal this event. Then, for every other received RTU, the LED tool will make a short flash. Simply count the flashes and you know how many station can be reached from this RTU (we call it connectivity test). After this connectivity test, the unit flashes rapidly to let you know the unit is alive. These flashes occur every half second. If the internal battery level drops below 5.6 volts, the unit will enter the misery state. In this state the unit reduces its activities to a minimum. Communication over the serial communication cable is not possible. Only the internal real-time clock is maintained and the power management functions are performed. Furthermore, when the internal battery level drops below 5.2 volts, the system switches completely off, effectively decoupling itself from the battery in order to protect it. Note:

If the LED tool was connected to the A753 when the unit shut down, the LED tool will restart the A753, which will initiate a shutdown again. If this happens to you, disconnect the LED tool and replace/recharge the battery. (This does not apply if a solar panel is connected to the SOLAR connector.) Table 1. LED Tool Blink Codes State Blink Code Description Misery mode Short flash every second Battery voltage below 5.5V but above 5.0V. Sensors are not sampled. Normal mode Short flash every 1/2 second RTU voltage is > 5.5V. RTU is up and running. Broadcast Long flash and then one short flash for every heard station Connectivity test ConfiguringanA753intheTelemetryGateway To configure the A753 with an A850 Telemetry Gateway, refer to the A850 Telemetry Gateway User's Guide. CHAPTER2 11 MaintainingandservicingtheRTU MaintainingandservicingtheRTU An A753 Series 4 addWAVE needs virtually no maintenance. It is waterproof and designed to withstand harsh environmental conditions

(-30 to +70 C, or -22 to 158 F), high RH values, water, and other non-corrosive liquids. It conforms to the European protection class IP65. This applies also to the connectors, as long as they are mated. Dont let unmated connectors on either the addWAVE RTU or the sensors be exposed to the environment for extended periods of time as this will seriously degrade their functionality. TheRTUbattery The internal battery supplies 6.2 volts and consists of a NiMH pack. The internal electronics manage the batterys charging/

discharging process, ensuring it a long life time. This approach, coupled with a remarkably low average power consumption, allows an addWAVE RTU to operate at least two weeks on a fully charged battery, as long as the analog and the counter values are stored in the internal memory every 15 minutes. Table 2 shows the addWAVE devices expected operation time on a fully charged battery under various conditions. Table 2. addWAVE Device Operation Time Radio Activity Sampling Rate Average Consumption

(mA) Estimated Operation

(days) No Low Heavy Low Low Heavy no sensors 0.85 132 no sensors 2.8 no sensors 5 900/3 900/15 900/15 4.2 6.3 9 40 22 26 17 12 However, if for some reason (wear-out or accident) the battery loses its capacity (noted in the software with repeated Battery low messages), it must be replaced. Make sure though, that the problem is really due to the battery and not to a defective or dirty solar panel. Adcon highly recommends that you frequently check and clean your solar panels. Rain and dust can cover the solar panels surface with a thin layer of dirt, effectively reducing its power output. Surrounding vegetation can also lower panel efficiency. CHAPTER2 12 MaintainingandservicingtheRTU Replacingthebattery If you have verified that the battery needs to be replaced, follow these steps to do so:

1. Open the lid by unscrewing the four screws in the corners of the A75x RTU, then remove the lid as shown in Figure 3. Figure 3. Removing the A75x Lid 2. The battery pack is connected to the electronics board by means of a PCB connector. Remove the battery packs plug from the PCB connector, as shown in Figure 4. Figure 4. Unplugging the PCB Connector CHAPTER2 13 MaintainingandservicingtheRTU 3. Unscrew the four screws of the plastic cover that holds the battery pack in place, then remove the cover. Figure 5 shows this step, revealing the A753 battery pack inside the RTU. Figure 5. A753 Battery Pack WARNING 4. 5. Remove the battery pack and replace it with a new one

(obtainable from Adcon). Put the plastic cover back into position and fasten the four screws. Insert the battery plug into the PCB connector. 6. Be sure to mount the rubber gasket of the lid properly e.g. not twisted, so that the units IP65 environmental protection is not affected. You must also be sure to not squeeze the battery cable. 7. Mount the lid back, taking care that the rubber gasket sealing the box is correctly in place, not twisted and free of dirt and soil. Screw the four cover screws back in, applying a moderate force. 8. CHAPTER3 14 UnderstandingConnectors Chapter3.PerformingAdvanced Functions CAUTION WARNING With the appropriate knowledge, you can configure A753 remote wireless units in the field by using a hyperterminal window. To configure the devices, you will need a special serial cable adapter (not supplied, but available from your Adcon distributor). Do not try to configure your devices if you are not sure what to do the unit might not communicate with the base station or function with the addVANTAGE software. Tampering with parameters for the devices may void your warranty or damage the device. In general, the commands described in this chapter are intended for technical support staff and users with a great deal of highly technical hardware and software experience. UnderstandingConnectors The devices have cable attachments called connectors. The connector type determines how the device communicates with the sensors or the computer. ThePOWERConnector CAUTION Solar Input, which enables charging the internal batteries. The A753 RTU has a Power connector used to interact with the device. The connector features the following pins:

To charge the unit without causing damage to the batteries or the charging circuit, the electrical characteristics in Table 3 on page 14 must be maintained. Table 3. Charger Requirements Parameter Output voltage Value 9-10VDC Output current (limitting is required) 100-300mA CHAPTER3 15 CommunicatingwiththeRTU Battery, which enables powering external circuits. The maximum current drawn by the attached circuit must not exceed 500 mA. RxD and TxD, which are used for serial communication (19200 baud) with the A753. The pinout of the POWER connector is shown in Figure 6. Figure 6. The POWER connector WARNING The serial communication line is 3V CMOS compatible. Therefore, a special adapter cable must be used to reach the RS-232 levels. You might want to charge the A753 with something other than the standard solar panel. In this case you must provide the electrical characteristics and configuration shown in Figure 7. Figure 7. Configuration for charging the A753 Note:

The Charger must have a current limited output of 300mA max! A standard wall adapter will not fit this need! See also Table 3 on page 14. CommunicatingwiththeRTU Note:

You can use a terminal program (like Windows Hyperterm) to connect to the A753 RTU. After you have installed the system, follow these steps to configure the device and set the default parameters:

To configure the A753, you must have a special adapter cable (item number 200.720.542 from your Adcon distributor). 1. 2. 3. Plug the round connector into the POWER connector of the RTU. Plug the USB connector into your PCs USB jack. If you are using the serial cable the first time, please follow the instructions to install the driver. CHAPTER3 16 BootingtheA753 4. Open a Hyperterminal or similar terminal application. 5. 6. Select the appropriate serial port and click OK. Configure your terminal as follows:

Select OK to open the terminal window. Press Enter to generate a response in the window. 19200 baud 1 stop bit 8 data bits No parity No protocol (neither hardware nor software) 7. 8. Note:

The A753 has two command line modes, bootloader and firmware. The RTU wont respond to any command during the boot process (this can take up to 2 minutes after connecting the battery). BootingtheA753 BootloaderMode This section is included for informational purposes. You will rarely need to boot the A753. However, when you do need to do so, you will work within a Windows Hyperterminal window or similar terminal program on your computer. When the A753 starts from a power-up reset (such as when you connect the battery to the unit), it enters the bootloader mode. If you press no keys in the interim, the A753 enters the firmware mode in five seconds. If you want to work with commands in the bootloader rather than continuing to the firmware mode, press the ESC button within five seconds after seeing the following sign-on message:

A753 with Bootloader V2.1, Firmware V2.1, Coprocessor V2.1 Copyright (C) 2011 Adcon Telemetry GmbH Press <ESC> within 5 seconds to start the commandline interface... You are in the command line interface of the bootloader. This interface enables you to perform certain commands such as upgrading to a new firmware. Note:

If you press no keys within 60 seconds, the bootloader command line interface will start firmware mode automatically. The bootloaderss prompt is the character >. Therefore, when you see this prompt, youll know you are in the bootloader mode. CHAPTER3 17 BootingtheA753 CommandsavailableinBootloaderMode For a list of the available commands, type HELP at the > prompt. Square brackets (like [arg] or [arg1 arg2]) enclose optional arguments,which may be omitted Note:

HELP Available commands:

coprocessor, 19200/115200) version ... show the version of the bootloader state ... show the board state reboot [id] ... reboot the RTU firmware ... start the firmware help ... display this helptext 0

Note:

The output of the HELP command may differ depending on the RTU type. The STATE command can be used to check the battery level, solar charger state and the RTUs current temperature. STATE Battery: 6.2 V (full charge) Temperature: 26 degree Celsius 0

FirmwareMode When you enter firmware mode by typing the command FIRMWARE, the following message is displayed in the Hyperterminal window:

FIRMWARE Checking firmware ........... found!

Checking storage ............... ok!

46339 0

The bootloader scans the program memory for a valid firmware by testing the checksum, which takes a moment. If everything is correct, the "firmware found!" message appears. CHAPTER3 18 UpgradingtheFirmware After checking the storage is done, which may take a moment, the device's identification number (for example, 46339) and error code (in this example, 0) are displayed. After another moment, the firmware modes command line interface prompt is displayed (#). If you need to return to bootloader mode when youre in firmware mode, enter the REBOOT command at the prompt. See Using Terminal Commands on page 21 for commands available in firmware mode. UpgradingtheFirmware Before upgrading the firmware, you must reboot the A753 to access the bootloader modes command line interface. Follow the procedure described under Booting the A753 to get into the bootloader. Before you start the upgrade, it is very important that you copy the new firmware image to the hard drive of the computer you use in the field or store it on your USB memory stick. You also need to know which version of the bootloader you are running. You can determine the version any of the following ways:

Look at the bootloaders sign-on message when you start it. At the bootloader modes prompt >, enter the VERSION command. In firmware mode, enter the Reboot <ID> command and look at the sign-on message. In firmware mode, enter VER at the # prompt. Now youre ready for the upgrade. 1. upgrade 115200 At the > prompt, enter the following command:

The upgrade process starts. For pre-1.7 versions of the bootloader, omit the speed parameter

(115200 used to be the default). For 1.7 and later versions, include the 115200 baudrate parameter. If you do not specify a baudrate, the upload runs at the default 19200 baudrate. Change the baudrate of your terminal to '115200' and hit <Return> to start flashing. 2. Select FileProperties to open the hyperterminals Properties dialog. Select a com port for the Connectusing field. 3. If your bootloader is version 1.7 or later and you used the > update command rather than the > update 115200 command, you can skip Step 4 through Step 6. The bootloader will use a baud rate of 19200. Note:

CHAPTER3 19 UpgradingtheFirmware 4. Click the Configure button to display the com ports Properties dialog (Figure 8 shows a COM1 com port). Figure 8. Hyperterminal and com port properties dialogs 5. 6. 7. 8. In the Bitspersecond field, select 115200. Select OK in the com ports Properties dialog to close it. Select OK in the hyperterminals Properties dialog to close it. Back in the hyperterminal window, press Enter to continue the upgrade.

The current firmware image must be erased for the upload. If you continue now, you *MUST* upload a valid firmware image for an A753!

firmware SerialCommunicationProtocol This protocol is based on a master sending commands and a node answering. The whole communication is conducted in plain ASCII, as strings, and numbers are represented in decimal format. All commands are terminated with a CR/LF combination. All responses

(answers) are terminated with the # character. GeneralFormatofaCommand The commands have the following format:

ID Command Param1 Param2 ... ParamN ID is the destination device. If you include an ID as part of a command, the node checks whether ID=ownID. If it does, the node executes the command on itself. If the ID is not the nodes ID, the node executes the command on a remote device, if such an ID exists. If the ID is missing, this implies that the command is addressed locally. Note:

Not all the commands can be relayed remotely. CHAPTER3 21 UsingTerminalCommands Command is the command proper, which can be composed of a variable string of characters (for example, SLOT). Each node can implement a set of commands depending on the functionality of the node itself. However, as a minimum requirement, a node recognizes the CMDS command, which returns a list with the commands accepted by the node. Param1 Param2 ... ParamN represent the parameters, which are command dependent. If you type no parameters when you issue a command, it is the equivalent of querying for information

(the GET version of a command). If you type parameters, you are issuing the SET version of a command and are setting the command to the parameters you typed. GeneralFormatofanAnswer The answers have the following format:

ID Command Result1 Result2 ... ResultN ErrResult #

ID is the answering device. If a command was further routed, it is the ID of the end device. The answer must always contain the ID on return. Command is the string representing the original command. It is supplied so that a master can distinguish between the answers it is waiting for, and out-of-band notifications (which may come, for example, over the radio port of a node). As with the ID, the command name must always be supplied. Result1 Result2 ... ResultN are the result values returned by the remote node. If the ErrResult is not zero, all other possible characters and/or strings until the end of the line might be ignored. ErrResult shows whether the command was successfully executed. If this value is 0, the command was successfully executed. If this value is other than 0, the command failed. The number may further indicate the error type. (See also Returned Errors List on page 32.) The answer string may contain any number of spaces or CR/LF characters between its components. However, after the terminator

(#), no other characters are allowed. UsingTerminalCommands Following is an excerpt of available commands and an explanation of their use. A complete list of all Series 4 commands is available upon request. Note:

You can type uppercase or lowercase characters because the commands are not case sensitive.

Sets the verbosity level of the device. This command is used for debugging only. The device will consume a lot more power when the verbosity level is greater than 0. This could discharge your battery and/or prevent proper operation. PARAMETERS A verbosity level (0...255). REMARKS RETURNS REMOTE EXAMPLE XDATA DESCRIPTION PARAMETERS REMARKS RETURNS SET only.

This command requests data for a list of logical channels for given timestamps. XDATA requires a lot of parameters for specifying what to retrieve. Please consult the A740 User Manual for detailed explanation of this command. The output of the command is not intended to be human readable. GET only. (This is a data retrieval command, local as well as remote.) A data block. REMOTE EXAMPLE XIMME DESCRIPTION PARAMETERS REMARKS RETURNS REMOTE EXAMPLE CHAPTER3 30 UsingTerminalCommands Yes, for a GET, but only one frame at a time.

Samples all inputs and immediately returns the sampled data. First parameter specifies the sample mode, which has to be 2 for raw data. The second parameter sets the maximum packet size. If you specify the third parameter, you can select a specific input connector. GET only. The command needs a specific delay to execute (for example, for the standard SST setting this delay amounts to two seconds). The delay is necessary to allow for the sensors to settle after applying power to them. A data block of io-port, raw adc and counter values. Yes.

The first column is the channel number. Channel 0 uses the internal sensors such as temperature and battery voltage. Channels 1- 4 are the connectors IO-A through IO-D. Column 6 of channels 1 - 4 are the counter values. The analog inputs are mapped to columns 3, 4, and 5. Column 2 of channel 1 or 2 displays the status of the four digital inputs DIG0 through DIG3. In the above example, the first analog input of IO-A (AN0) is 1024 and the IO-A counter (RAIN0) has a value of 153. ANLGTHRESHOLD DESCRIPTION PARAMETERS The RTU does not store data for analog channels when the voltage is less than the given cut-off threshold for that channel, and thus save radio/GSM trafc). A threshold, specied as ADC value (0..65535 for 0..2.5V) and a ANLG channel. The channel is the ANLG channel (0..11) or omitted (to set the threshold for all analog inputs) CHAPTER3 31 UsingTerminalCommands REMARKS RETURNS REMOTE EXAMPLE GET/SET. The current settings. Yes.

CNTRTHRESHOLD DESCRIPTION PARAMETERS The RTU does not store data for counter channels when the number of pulses is less than the given cut-off threshold, and thus save radio/

GSM trafc). A threshold, specied as number of pulses on the CNTR input pin

(0..65535) and a CNTR channel. The CNTR channel (0 = IOA, 1 = IOB, 2 = IOC, 3 = IOD) or omitted (to set the threshold for all counter inputs) REMARKS RETURNS REMOTE EXAMPLE DYNSLOT DESCRIPTION GET/SET. The current settings Yes.

The dynamic slot switching function checks whether the measurement value of the given sensor matches the given condition, then switches between two operating modes:

normal mode (when the condition is false and the lock timer is zero) exception mode (when the condition is true and the lock timer is nonzero) The rules for the mode switching are:

CHAPTER3 32 ReturnedErrorsList when the condition becomes true the rst time, exception mode is entered and the lock timer is set while the condition is true, the lock timer is set at every sample, thus does not reach zero while the condition is false, the lock timer is decremented if not already zero when the lock timer reaches zero, normal mode is entered the SLOT settings are only changed when the mode changes Thus, the RTU enters exception mode whenever a sample value matches the condition, and stays there until the sample value does notmatch the condition for at least the given locktime (this prevents excessive wear of the EEPROM due to jitter in the measurement value). GET/SET. Yes. we set up theDYNSLOT feature to measure IOA and IOB every minute when the sensor value on cabling 1 is more than 1.25 Volts (ADC value 32768):
