Introduction 1 Introduction This manual explains the hardware aspects of Adcon’s A733, A732, A731, and A733GSM/GPRS remote telemetry units (hereafter referred to as A73x), including installation issues and certain parameter configurations. The manual is divided as follows: • "Introduction,” which gives some general information and document conventions. • "Using the A73x RTU,” which details the installation and use of the remote telemetry unit. • "Performing Advanced Functions,” which contains technical information for the advanced user. • "Specifications,” which describes operating parameters for the devices. 1.1 About the A73x RTU family The A731, A732, and A733 RTUs incorporate an A431 radio module operating in the 430 to 470 MHz range, making it adaptable to most radio communication regulations in the world. The output power is variable up to 0.5 W, while the modulation is narrow-band FM (6.25, 12.5 or 25 kHz channel spacing). The A733GSM/GPRS RTU incorporates a GSM module and uses the standard GSM network for retrieving telemetry data (900/1800 MHz in Europe, 850/1900 MHz in the US). The A73x is a rugged RTU, complying with the IP65 ingress protection class (NEMA 4). Depending on topography it ensures a reliable wireless connection to other A73x RTUs, an A730MD or A730SD device, or an A840 Telemetry Gateway over a distance of up to 20 km (12 miles). The A733GSM/GPRS has no such limitations; however, your cellular service provider must cover the site where you want to install the RTU. The A733GSM/GPRS operates in conjunction with the A840 Telemetry Gateway only. 7
Compliance Statement and Warnings 1.2 Compliance Statement and Warnings The A73x addWAVE (radio version) must not be used with any antenna other than the one supplied by Adcon (or an antenna with identical technical specifications).

Using the A73x RTU 2 Using the A73x RTU The A73x series of remote telemetry units (RTUs) is part of the A730 series. For testing purposes, you should have an A730SD/A730MD and/or an A840 Telemetry Gateway installed before you install your A73x RTU. For information about installing the A730SD or A730MD, refer to the addVANTAGE A730 User Guide Version 3.4x. For information about installing the A840, refer to the Base Station, A840 Telemetry Gateway and Wireless Modem A440 User Guide. The A733GSM/GPRS RTUs operates in conjunction with an A840 Telemetry Gateway only. 2.1 Opening the packages The A73x RTU package contains the A73x RTU, an antenna, and a pipe clamp. If ordered, the following items come in separate packaging: • A solar panel with pipe clamp • A set of aluminum poles • An LED tool • Sensors and cables, one box for each sensor, and fastening ties in each sensor box 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. Fig. 1 and Fig. 2 show the top and bottom view of an A733 addWAVE RTU. 11
Installing the RTU Fig. 1: addWAVE RTU (top) Fig. 2: addWAVE RTU (bottom) 2.2 Installing the RTU The following restrictions apply: • In general, the typical “line-of sight” distance the RTU can communicate is 10 km (6 miles). This is valid if both the RTU and its partner device are mounted on a 3 m mast (9 ft.); the results may vary under different conditions, and you can sometimes achieve greater distances. Note: The above does not apply to the A733GSM/GPRS RTU. In principle there is no distance limit for this type of device as long as your cellular provider covers the area where it is installed. • As with all wireless communication devices, the higher the transmitter is, the better the communication will be. • All A73x devices accept the standard Adcon sensors (A731 excluded), which are different from the A730MD series in that they provide IP65 class protection. All Adcon sensors are delivered by default with this new type of connector. An adapter cable is optionally available to connect current sensors to the RJ-12 ports of the A730MD stations. Note: For technical reasons, Adcon cannot provide adapters for the RJ-12 connector to the A73x devices. 12
Using the A73x RTU 2.3 Special notes for the A733GSM/GPRS RTU The A733GSM/GPRS RTU is based on a GSM module which employs a GSM cellular network to transmit the telemetry data. Before you install such a device, you must make sure a sufficient signal for proper operation of the RTU on the site where you plan to use it exists; you can do this by using a standard cellular phone operated by the same cellular provider. You can also verify that you can communicate with the RTU simply by calling it as you would a normal cellular phone. The two ways to operate your A733GSM/GPRS RTU are as follows: GSM mode: In this case please ask whether your provider offers CSD connections. Most cellular/GSM providers use a different telephone number for data communication than for voice communication. Don’t forget to ask for this data number when you order your SIM card, if you do not use the RTU in GPRS mode! When your modem calls the RTU from a land line, use the data number: else the RTU will answer, but immediately send a busy tone, as the voice call cannot connect to a data terminal. Voice calls cannot connect to a data terminal, so you need to set up your modem to use the data number when calling the RTU from a land line. 1. 2. GPRS mode: Please make sure your SIM card is well suited for GPRS operation. You also need to insert your SIM card into the SIM holder inside your A733GSM/GPRS RTU by following these steps: 1. Open the lid of the A733GSM/GPRS RTU by unscrewing the four bolts in the corners of the RTU and then remove the lid as shown in Figure 3 . Fig. 3: Removing the A73x Lid Note: You don’t have to remove the battery plug from the base board during this operation, but make sure nothing is attached to the POWER connector. 13
Special notes for the A733GSM/GPRS RTU Fig. 4: Installing the SIM card in the A733GSM/GPRS RTU 2. Locate the SIM card holder and open it by sliding it as indicated by the red arrow (see Fig. 4, left). 3. Raise the holder top and slide the SIM card into it (Fig. 4, center). 4. Snap the holder top back on and slide it back as shown again by the red arrow depicted in Fig. 4, right. 5. Remount the lid, taking care that the rubber gasket sealing the box is not out of place and is free of dust or dirt.  WARNING: Be sure to mount the rubber gasket properly, so that the unit’s IP65 environmental protection is not affected. 6. Put the four screws back in place, applying moderate force (approximately 150 to 200 Ncm), tightening crosswise. For additional information, please contact Adcon Telemetry or your local reseller of Adcon Telemetry products. This completes the SIM-card installation. Now you will need to activate the card by using a personal identification number (PIN). You will find this number in the package that you got from your cellular service provider. Before you can activate your card, the A733GSM/GPRS must be properly powered. As the RTUs are delivered from the factory with the batteries uncharged (they have a longer shelf life in this state), you must charge the batteries first. The best way to do this is to attach the solar panel to the power connector and expose the RTU to the sunlight for at least one hour. If the sky is overcast the battery will still charge, but at a lower rate; in this case allow at least four hours for charging. You need a serial adapter cable to enter the PIN; you can get the cable from Adcon Telemetry or your reseller. When you have the cable, you can proceed as follows: 1. Connect the serial cable from the COM port of your PC to the RTU. Configure your terminal as follows: 19200 baud, 1 stop bit, 8 data bits, no parity, no handshaking protocol (neither hardware nor software). For more details, see “Communicating with the RTU” on page 27. 2. Make sure that you can communicate with the RTU by pressing the enter key: the device will answer with its own ID number and a hash sign (#). 3. Type the command GSMPIN nnnn (where nnnn is the PIN code) and press enter. If the PIN is conforming to the standard PIN format requirements the RTU will answer id gsmpin 0, where id is its ID number (this is NO PIN check with your provider!). This completes the PIN entry procedure. You can check the status of the A733GSM/GPRS RTU at any time by typing the GSMSTAT command. This command returns a list of GSM parameters: 14
Using the A73x RTU #gsmstat 26142 gsmstat GSM modem on: Yes SIM card found: Yes PIN set: Yes PIN accepted: Yes Sleepmode OK: Yes PUK required: No Default IMEI nr: No GPRS: Yes GPRS IP conn.: No Attempts left to enter PIN: 3, PUK: 10 0 # The above shows that: • The GSM modem is on. • A valid SIM card is inserted. • The SIM card was activated with a valid PIN code. • The GPRS feature is enabled. • The GPRS connection is not established. The GPRS-related lines from the above-displayed output of the GSMSTAT command are shown only by RTU firmware versions capable of the GPRS communication mode (for version information see below). Other information is also listed, but it is of no concern to the user, except the PUK required entry. If this parameter is Yes, it can be the result of entering a wrong PIN three times in a row. You can see this also in the last string displayed by the GSMSTAT / GPRSSTAT command (number of retries left). To reactivate the card you will need its PUK number, which you also get from your cellular provider with the SIM card. To reactivate the card, enter the command GSMPUK pppppppp nnnn (where pppppppp is the PUK code and nnnn is the new PIN). Note that the new PIN is used immediately to activate the SIM card. The command GPRSSTAT is a synonym for GSMSTAT.  WARNING: Your A733GSM/GPRS RTU has an internationally unique identification number (IMEI). This number is on a leaflet packaged with your device, and you will need it if you lose the device. Please keep the number in a safe place. 2.3.1 GPRS usage of an A733GSM/GPRS RTU Configuring the GPRS Parameters To configure your A733GSM/GPRS RTU for usage with GPRS, ensure that the module has firmware version 2.10 or above installed. If your A733GSM/GPRS RTU features a Motorola GSM/GPRS module, be sure to have firmware version 2.14 or higher installed. Verify that you have configured the GSM Parameters as described in the previous section (GSMPIN, GSMROAM). Note: If you want to use only the GSM features of the RTU, you have to set “GPRSPORT 0“ to disable the GPRS capabilities. The power consumption will then be as low as with the older GSM-only units. 15
Special notes for the A733GSM/GPRS RTU Set/configure the following parameters through a terminal connection to enable GPRS connection to your ISP: GPRSAPNSERV “[servername]” where [servername] is the name of the ISP's GPRS access server (required) GPRSAPNUN “[username]” where [username] is the name of the GPRS user’s name for the ISP (might be optional) GPRSAPNPW “[password]” where [password] is the password for the GPRS user (might be optional) The following examples show the GRPS parameters for an Austrian mobile phone services provider: GPRSAPNSERV “A1.net” GPRSAPNUN “ppp@A1plus.at” GPRSAPNPW “ppp” Note: Please take extreme care not to misspell the GPRS-parameter values, and not to switch the case of letters. Misspelled names/entries could cause the RTU not to connect to the GPRS network or A840. Configuring the TCP Parameters The A733 GSM/GPRS RTU will only connect to the A840 Telemetry Gateway if the following TCP Parameters are set: GPRSHOST “[a840-ipaddress]” where [a840-ipaddress] is the IP address of the A840 Telemetry Gateway the RTU has to connect to. For RTUs with built-in Motorola GSM/GPRS modules, this parameter must be an IP address in decimal dotted notation, e.g. 123.45.23.45. GPRSPORT [portnumber] where [portnumber] is the port number where the communication with the A840 Telemetry Gateway will occur. If this parameter is set to 0, the RTU will operate only in GSM mode. GPRSDNS1 [dotted_dns_address] (optional) first DNS server address of your GPRS network operator (e.g. 123.34.2.34). This and the next command are not available on RTUs with built-in Motorola GSM/GPRS modules. GPRSDNS2 [dotted_dns_address] (optional) second DNS server address. Note: When using an Internet Firewall in front of the LAN where the A840 Telemetry Gateway resides, be careful to properly configure the firewall and the A733GSM/GPRS RTU connection parameters [a840-ipaddress] and [portnumber]. This is particularly important if you use NAT (network address translation) on your firewall.  CAUTION: If you are using an Internet Firewall in front of your A840 Telemetry Gateway, allow connection to devices only with IP addresses from your GPRS network operator’s IP networks to your A840 Telemetry Gateway. When your GPRS network operator changes the addresses of his IP networks, you must adjust your firewall’s filters appropriately. 16
Using the A73x RTU Configuring the RTU GPRS Connection settings Use the following commands to define the intervals the RTU will wake up and connect to the A840 Telemetry Gateway: GPRSCONNALIGN [align] alignment of calls in seconds (default 28800, i.e. 8:00). NOTE: These wall clock times are either UTC or local time of your A840 Telemetry Gateway, depending on the setting of the “Wireless Network uses:” switch on your A840 Telemetry Gateway. GPRSCONNINT [interval] interval between two connection attempts in seconds (default 43200, i.e. 12 hours). GPRSSECRET <secret> this 32-bit integer (0 to 4294967295) has to be set for the RTU and the gateway. This is a shared “secret” or password. GPRSTMOUT [interval] idle time out in seconds (default 3600, i.e. 1 hour). Connections that are idle this long will be terminated by the RTU. Set these parameters according to the needs of your application. Make sure you choose the proper parameters for GPRSTMOUT (to allow for appropriate idle times, but not ones that are too long), GPRSCONNALIGN and GPRSCONNINT (for specifying the proper connect times of the RTU). Also take into account, that the RTU will be polled for data by the Adcon Telemetry Gateway within the GPRSTMOUT time. If you need your RTU to detect within an hour that the connection to the Adcon Telemetry Gateway is broken, set the GPRSTMOUT to 3600 seconds. But make sure, that the RTU is polled for data at least once within that time span. Note: Keep in mind that "calling" the A840 Telemetry Gateway costs battery power. Recommended Settings for A733 GSM/GPRS with WaveCOM Module: On the RTU: • GPRSCONNINT 3600 or 7200 or 10800 (1, 2, 3 hours connection interval) • GPRSCONNALIGN is per default set to align the connection to 8:00 (UTC) On the gateway: • Check the "Close connection after poll" checkbox for the RTU 2.4 Field Installation Installing A73x RTUs in the field is a fairly simple process. You’ll perform a connectivity check with an LED tool (does not apply to A733GSM/GPRS RTUs). The LED tool is shown in Fig. 5. 17
Field Installation Fig. 5: LED Tool Note: The LED tool is a blind plug to be plugged into the POWER connector. Follow these steps to install an A73x RTU in the field: 1. Review the installation area and choose the best site (for the A733GSM/GPRS RTU, skip to Step 3). 2. Perform a connectivity check using the LED tool: a. Insert the LED tool into the POWER connector and wait up to 10 seconds. If the unit connects to at least one station (or a base station), it will light up the LED for about 4 seconds. b. Keep observing the LED tool and, after several more seconds, the LED will blink one or more times (the number of blinks indicates the number of stations it has successfully contacted). Note: For the A733GSM/GPRS, make sure that you have a sufficient RF signal from your cellular service provider. The simplest way to achieve this is to check a cellular phone operated by the same cellular service provider on the site where you want to install the RTU. 3. Assemble your pole set. 4. Put an Adcon plastic cap into the top of the pole and secure it with a pie clamp to protect the top of the pole from damage. 5. Using a hammer, drive the 80 cm aluminum rod into the ground. 6. 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 A73x RTU. Note: The solar panel can be mounted under or behind the A73x RTU, but make sure that the RTU does not shadow the panel. 7. Fasten the A73x RTU to the top of the pole with a pipe clamp. Adcon recommends that you perform another connectivity test (not for the A733GSM/GPRS), if you can, to check the positioning of the device.  WARNING: If you turn the fastening screws too tightly, you could damage the connectors. 8. 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. 9. If you have SDI-12 sensors, attach the SDI-12 adapter and the respective sensors. For more details about installing the SDI-12 adapter, consult the leaflet that came with the adapter. 10. Secure the extra length of the sensor cables to the pole with cable ties. This completes the installation of your A73x RTU. If one of the I/O connectors is left unused, use the cap specially provided to protect it against moisture and dust. Be sure to make a note of the following information because you’ll need it when you configure the device in the software: • Serial number for each RTU (for the A733GSM/GPRS RTUs, the data telephone number also) • Type of sensors connected to each RTU and to which I/O port 18
Using the A73x RTU 2.5 More about the LED tool The LED tool allows you to rapidly check the status of an A73x RTU. After you insert the LED tool into the POWER connector, the unit waits up to two seconds and then sends a broadcast frame (does not apply to the A733GSM/GPRS RTU). If a nearby listening station or receiver decodes the frame, it will answer back—this may take up to 10 seconds. When the RTU receives an answer, the LED tool lights up for about 4 seconds. After another few seconds, the LED lights up one or more times, depending on the number of stations/receivers that answered its broadcast frame. In addition, the LED always blinks briefly at 0.5 second intervals to indicate that the unit is alive and the internal battery has enough energy to operate. If the blinking interval lengthens to 2 seconds, the battery has become undercharged (that is, under 5.6 volts but over 5.2 volts)—which is called the misery state. In this state, an A73x RTU reduces its activities to a minimum. The radio unit is switched off, the sensor sampling ceases, and no data is stored in the internal memory. Only the internal real-time clock is maintained and the power management functions are performed. If the battery level drops below 5.2 volts, the system switches completely off, effectively decoupling itself from the battery to protect it. In this case the LED tool stays off permanently. An A73x RTU in such a situation will restart only after connecting it to an external power supply (even a solar panel under low light conditions). Note: New A73x RTUs are delivered with their internal batteries unformatted, meaning they are completely discharged, and you should install them only on sunny days. The battery will be fully charged after two consecutive sunny days, but you should get an LED light-up after several minutes of charging in the sunlight. Testing GSM/GPRS/A840 Connection with LED Tool When the LED tool, the solar panel, or the SC cable is connected to the RTU, the modem starts and tries to connect to the gateway. When you connect an LED tool, the tool indicates the different states of the modem connection with blink-codes (for details see below). What happens after the GPRS unit successfully connects to the A840 Telemetry Gateway is determined by the configuration of the gateway. If the “Close connection after poll" check box is checked, a poll cycle is conducted immediately (and if the time is not yet set at the RTU, it will be set). If "Close connection after poll" is not selected, a poll cycle is conducted according to the poll settings on the gateway (either at the specified poll times or at the specified poll interval). In this mode the time on the RTU will be set on the first poll cycle. Misery state (battery voltage below 5.5V but above 5.2V): Short blink every other second. Normal mode, but GSM/GPRS modem not yet started: Short blink every half second. Modem in GSM mode (mostly transitional mode): 3 seconds on, half a second off. 19
Configuring an A73x RTU in the addVANTAGE software Modem in GPRS network: 3 seconds off, half a second on with short blinks in the off periods. TCP connection to Gateway established: Blinking in a half-second-on, half-second-off rhythm. 2.6 Configuring an A73x RTU in the addVANTAGE software To configure the A73x RTU with an A840 Telemetry Gateway and the addVANTAGE 4 Pro software, check the Base Station, Telemetry Gateway A840 and Wireless Mode A440 User Guide. 2.7 Maintaining and servicing the RTU The A733 unit 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. These standards also apply to the connectors, as long as they are mated or capped. Don’t let unmated/uncapped connectors on either the A73x RTU or the sensors be exposed to the environment for extended periods of time. When used in coastal areas with high salt content in the air, use an extra protective case to avoid corrosion. Avoid spraying agrochemicals on your RTU, as they might form very aggressive compounds. 2.7.1 The RTU battery The internal battery supplies 6.2 volts and consists of either a NiCd (radio RTUs) or a NiMH (GSM/GPRS) battery pack. The internal electronics manage the battery charging/discharging process, ensuring it a long life. This approach, coupled with a remarkably low average consumption (6 mW for the standard RTU and 15 mW for the GSM RTU), allows an A73x RTU to operate at least two weeks on a fully charged battery, with the following conditions: • The channel has moderate radio activity, with requests every 15 minutes. • Total consumption of attached sensors is 100 mA. • The sensors are sampled once every minute and an averaged slot is stored in the internal memory every 15 minutes. Table 1 shows the A73x device’s expected operation time on a fully charged battery under various conditions. The sensor consumption totals 100 mA. Radio Activity Sensor Sampling Average Consumption (mA) Estimated Operation (days) 20
Using the A73x RTU (samples/15 min) No No sensors 0.85 132 Low No sensors 2.8 40 Heavy No sensors 5 22 Low 3 4.2 26 Low 15 6.3 17 Heavy 15 9 12 Table 1: A73x Device Operation Time Note: Low radio activity means that one base station and between one and three A730MDs/A73xs or A730SDs are active on the same operating frequency as the A73x remote station under test. Heavy radio activity means that approximately 30 devices are on the same channel. However, no routing is used. Table 1 does not apply to the A733GSM/GPRS RTU. However, if for some reason (by wearing 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 check the solar panels’ state and clean them often. The rain droplets can splash thin layers of soil on the panels, thus reducing their power output. The surrounding vegetation can also lower the panels’ efficiency. 2.7.2 Changing the battery 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 A73x RTU, then remove the lid as shown in Fig. 6. Fig. 6: Removing the A73x Lid 2. The battery pack is connected to the electronics board by means of a PCB connector. Remove the battery pack’s plug from the PCB connector, as shown in Fig. 7. 21
Maintaining and servicing the RTU Fig. 7: Unplugging the PCB Connector 3. Unscrew the four screws of the plastic cover that holds the battery pack in place, then remove the cover. Fig. 8 shows the A733 battery pack inside the RTU. Fig. 8: A733 Battery Pack 4. Remove the battery pack and replace it with a new one (obtainable from Adcon). 5. Replace the plastic cover and screw the four screws back in. 6. Carefully remove the rubber gasket in the lid and replace it with the one supplied with the battery. 7. Insert the battery plug into the PCB connector. 8. Remount the lid, taking care that the rubber gasket sealing the box is properly seated.  WARNING: Be sure to mount the rubber gasket properly, so as to retain the unit’s IP65 environmental protection. 9. Screw the four screws back in, applying a moderate force. 22
Using the A73x RTU 23
Performing Advanced Functions 3 Performing Advanced Functions With the appropriate knowledge, you can configure the A73x devices in the field by using a HyperTerminal window. To configure the RTU, you need a special serial cable adapter (not supplied, but available from Adcon). Do not try to configure your A73x devices if you are not sure what to do—the unit might not communicate with the remote measuring station or function with the addVANTAGE software. Tampering with parameters for the A73x 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. In the system architecture, the base station and RTU are both considered to be nodes. The base station is called the master node, or master, while the RTU is called the slave node, or slave. 3.1 Understanding connectors The A73x devices have cable attachments called connectors. The connector type determines how the device communicates with the sensors or the computer. 3.1.1 The RTU connectors The A73x RTU uses standard 7-pin sensors for all available I/O ports (A731 addRELAY excluded), model Binder 702 and 712 series or equivalent, that are identical. Each connector has three analog inputs (0 to 2.5 volt) and two digital input/outputs, one of which you can use as a pulse counter (for example, a rain gauge). Fig. 9 illustrates the individual pins of an I/O connector. 25
Understanding connectors Cabling 1Cabling 2Cabling 3Switched BatteryDigital I/OPulseCounter Ground1234567 Fig. 9: Pins on an I/O Connector (Top View) Using Adcon’s 7-pin Y-cable lets you attach more than one sensor to one connector.  CAUTION: To avoid cabling conflicts, first verify in the addVANTAGE software that the sensor combination in the configuration you want is allowed. If you find no conflicts, you can physically attach the sensors to the A73x RTU. 3.1.2 The POWER Connector The A73x RTU also has a POWER connector, which allows for: • External supply (battery or any DC source from 5.6 to 10 volts) • External charge supply (either a solar panel or an AC adapter) if an internal rechargeable battery is used • Communication over serial lines, at 19200 baud Fig. 10 illustrates the connections available at the POWER connector. RxDTxDGroundExt. PowerBattery12345 Fig. 10: A73x POWER Connector (Top View)  WARNING: The serial line is 3-volt CMOS compatible so you must use a special adapter cable to reach the RS-232 levels. Also, if you use an external battery, you must disconnect the internal battery. You might want to use the POWER connector with something other than the standard configuration. For example, to connect an external battery to the RTU, disconnect the internal battery and use the configuration shown in Fig. 11. 26
Performing Advanced Functions ShortBattery (5,6 to 10V)12345+- Fig. 11: A73x Connection with External Battery To use the internal battery with a different power supply (charger) than the provided solar panel, disconnect the solar panel and use the configuration shown in Fig. 12. ShortCharger (9 to 10V, 100 to 300mA)12345+- Fig. 12: A73x Connection with External Power Supply And to use an external battery with a different power supply (charger) than the provided solar panel, disconnect the internal battery and solar panel and use the configuration shown in Fig. 13. ShortCharger (must fit the battery)12345+ +Battery (5,6 to 10V) Fig. 13: A73x Connection with External Battery and Power Supply 3.2 Communicating with the RTU You can use a Windows HyperTerminal window to connect to the A73x RTU. After you have installed the system, follow these steps to configure the device and set the default parameters: Note: To configure the A73x RTU, you must have a special adapter cable (available from Adcon) and plug it into the POWER connector. 1. Start a HyperTerminal session. 2. Select the appropriate serial port and click OK. 3. Configure your terminal as follows: • 19200 baud • 1 stop bit - 8 data bits • No parity • No protocol (neither hardware nor software) 4. Select OK to open the terminal window. 5. Press Enter to generate a response in the window. 27
Serial communication protocol 3.3 Serial communication protocol This protocol is based on a master sending commands and a node answering; the whole communication is conducted in plain ASCII, as strings. When exchanging numbers, they are represented in decimal format. All commands are terminated with a CR/LF combination. All responses (answers) are terminated with the # character. 3.3.1 General format of a command 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 node’s 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 of the commands can be relayed remotely. • 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 recognized 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. 3.3.2 General format of an answer 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 be always 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 may 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 54.) The answer string can contain any number of spaces or CR/LF characters between its components; however, after the terminator (#) no other characters are allowed. 28

This command allows you to change the assignment of physical analog input ports to data frame positions. PARAMETERS None for inquiry. Position of value in frame and input channel for rerouting operations. RETURNS List of current routings. REMARKS On inquiry the input channels are output in the order of their position within the data frame (note: input channel numbers start with 0). On changing the input channel routings, the first parameter specifies which data frame position to use for the data value, and the second parameter determines which input channel to use. The input channels on A733 and A733GSM/GPRS are numbered from 0 to 11, but on A732 and A723 they are numbered from 0 to 5. Input channels 0 to 2 are taken from I/O A, cabling 1 to 3; input channels 3 to 5 are taken from I/O B, cabling 1 to 3; and so on.

The port number, the OFF and the ON times (in seconds), both as 16-bit integers Result (OK or ERROR). 1101 MFS – Monostable function, start with the specified bit in ON state (set). The port number, the ON and the OFF times (in sec-onds), both as 16-bit integers Result (OK or ERROR). 1110 MVFR – Multivibrator function, start with the specified bit in OFF state (reset). The port number, the ON and the OFF times (in sec-onds), both as 16-bit integers Result (OK or ERROR). 1111 MVFS – Multivibrator function, start with the specified bit in ON state (set). The port number, the ON and the OFF times (in sec-onds), both as 16-bit integers Result (OK or ERROR). RETURNS The return result depends on the control byte. However, whatever the return result is, it includes the control byte. REMARKS The general behavior is that a PORT command issued on a certain port bit will override any previous PORT commands. For example, if a port was configured as input and then an MFR (monostable function) was issued, the port automatically switches to output. A new MFR or similar function clears the status of the port and starts from scratch, even if the previous command was not finished. After power loss all port are set to be input ports, only notification settings are kept in non-volatile memory and thus newly occurring notification conditions are recorded and reported. Monostable- or multivibrator-function settings are lost. When entering misery state, the RTU stops monostable or multivibrator functions in the state they are when entering misery state, and when leaving misery state the monostable or multivibrator functions are continued where left off.

The frame type 60 contains SDI-12 data only. SDI-12 specific parameters are explained below: • SDI count —the number of SDI values following in the SDI data block. • SDI offset — the offset in the SDI-12 frame. Usually it is 0 (no offset is used). • SDI available —the number of SDI-12 sensor values effectively returned. The difference between the SDI count and SDI available indicates missing sensors (down or damaged). Usually these two values are equal. • SDI values —a number of SDI-12 data blocks, each consisting of four values: • SDI address • SDI method • SDI index • SDI value (floating point) You can also see the example below. For additional information about the significance of the SDI address, method, and index, please refer to the SDI-12 standard specification (http:// www.sdi-12.org).

Notifications 3.5 Notifications Notifications are frames sent asynchronously by devices that are otherwise slaves. The notifications are received by a device closest to the host and then sent to the host. If the host is not available, the receiving device stores the notification and waits until the host questions it. At this point, the device informs the host that it has a notification. It is then the task of the host to issue a command to read the respective notification. Before a device can issue a notification, the notification must first be enabled. Special frames are used to this end, depending on the notification type. If an end device is not able to send a notification due to radio propagation or other kinds of communication problems, it will store the date/ time when the notification took place. As soon as the communication is re-established, the device tries to send the notification again. Note: To avoid collisions, the device waits a random time (up to 10 seconds) before sending the notification frame. The following notifications are currently implemented for the A733 device: • NOPC—Notification On Port Change (see “PORT” on page 40); • NOTR—Notification On Threshold Reached (see “ANLG” on page 32). Note: The A733GSM/GPRS RTU currently does not support notifications when used in GSM operation mode. 3.6 Returned errors list Following are error messages you might get. 3.6.1 Command line interpreter 1 — nonexistent command 2 — command line buffer overflow (input line too long) 3 — internal error 4 — reserved 5 — missing or false parameters in command 6 — operation not implemented 7 — remote operation not allowed 8 — Invalid IMEI checksum number 9 — command not supported in this configuration 3.6.2 Device descriptors and storage handler 10 — device not found (attempt to perform a command on a nonexistent device) 11 — device already exists 12 — reserved 54

Upgrading an older A733 GSM 5 APPENDIX 5.1 Upgrading an older A733 GSM If you want to update an older A733 addWAVE GSM RTU for use with GPRS, first make sure that the GSM module features the proper firmware. This chapter applies only to RTUs with WaveCOM GSM-modules (serial numbers below 35.000). To check the firmware version of the RTU: − connect your computer via Adcon A720SC cable to the RTU − type INFO and look for the version number, which must be at least 2.10: 26151 info 0 0 22/3/2006 13:15:17 2.10 ... − enter GSMX at the command prompt #GSMX Input will now be sent directly to the GSM modem. Press <ESC> to exit. Now enter the command ATI3 The output should be something like 641b09gg.Q2406B 1339080 041604 16:04 The first 3 digits have to be "641" or higher. If not, you need to upgrade the module firmware. You can also verify that the module is suited for an upgrade. The "Q2406B" after the period is the module type, which can be either Q2406B or Q2426B. Other modules such as the Q2403A cannot be upgraded. Then enter at+wopen=2 and you should get +WOPEN: 2,"AT v02.10","AT v02.10" If one of the version numbers is different, or "AT v02.10" is shown only once, the IP stack is missing in the GSM module. 60
APPENDIX Then enter at+wopen=1 and you should get OK If you get any other message than "OK,” the IP stack needs to be enabled. You need a special code to do so.
