Introduction 1 Introduction This manual explains the hardware aspects of Adcon’s A733, A732, A731 and A733GSM remote telemetry units (further referred to as A73x), including installation issues and certain parameter configurations. The manual is divided as follows: 1.1 • "Introduction", which gives some general information and document conventions. • "Using the A73x RTU", which details the installation and use of the remote telemetry unit.
Compliance Statement and Warnings supports the SDI-12 bus implementation. The unit is based on a powerful 8 bit Flash RISC microcontroller, that can also be field programmed (software upgraded). The only difference between these devices and the A732 and A731 is the number of analog and digital interfaces. 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.
Introduction This device complies with Part 15 of the FCC Rules. Operation is subject to the following conditions: 1. this device may not cause harmful interference, 2. this device must accept any interference received, including interference that may cause undesired operation, 3. any manipulations on this device other than mentioned in this manual void the FCC type approval. 1.3 Conventions Certain conventions apply in this documentation.
Using the A73x RTU 2 Using the A73x RTU The A73x series of remote telemetry units (RTU) 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.
Installing the RTU Fig. 1: Fig. 2: 2.2 addWAVE RTU (top) addWAVE RTU (bottom) Installing the RTU The following restrictions apply: • Note: Note: 10 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. The above does not apply for the A733GSM RTU.
Using the A73x RTU 2.3 Special notes for the A733GSM RTU The A733GSM 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 that there is sufficient signal for proper operation of the RTU on the site you plan to use it; this is done best by using a standard cellular phone operated by the same cellular provider.
Special notes for the A733GSM RTU 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. Mount the lid back, taking care that the rubber gasket sealing the box is not out of place and 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.
Using the A73x RTU • the GSM modem is on • there is a valid SIM card inserted • the SIM card was activated with a valid PIN code. Additional information is also listed but this should be of no concern for the user, except the PUK required entry. If this parameter is Yes, it can be the result of entering a wrong PIN code three times in a row. You can see this also in the last string displayed by the GSMSTAT command (number of retries left).
More about the LED tool 4. Using a hammer, drive the 80cm aluminum rod into the ground. Prior to that put an Adcon plastic cap into the top of the pole and secure it with a pie clamp in order to protect the top of the pole from damage. 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 A73x RTU.
Using the A73x RTU Note: 2.6 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.

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 will need a special serial cable adapter (not supplied, available from Adcon). Do not try to configure your A73x devices if you are not sure what to do—the unit may not communicate with the remote measuring station or function with the addVANTAGE software.

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 • Note: 3.3.
Performing Advanced Functions 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. 3.4 Using terminal commands Following is a list of available commands and an explanation of their use. Note: You can type uppercase or lowercase characters because the commands are not case sensitive. CMDS AVAILABLE FOR A731 A732 A733 A733GSM DESCRIPTION Returns a list of supported commands.
