    What are addIT devices? Adcon’s addIT devices (A720, A723 and A720B) are uniquely suited to your remote measuring needs. The A720 and A723 devices are remote telemetry units (RTU) that can be used with Adcon and other compatible sensors to track those parameters important to you.

  • Page 6: Installation Issues

    CHAPTER 1 Introduction Installation issues The addIT A720/A723 RTU can be used in one of the following ways: • Installed in the vicinity of an Adcon remote measuring station (A730MD), the addIT RTU can use the A730MD station to relay its data to a base station (A730SD or A840). If the base station is close enough to the addIT RTU, the RTU can communicate directly with the base station.

    • Note: For technical reasons, Adcon cannot provide adapters for Conventions Certain conventions apply in this documentation. Italics Bold fixed font File Note A730MD remote station, but they cannot communicate with each other. All addIT devices accept the standard Adcon sensors; however, the connectors are different.

    Chapter 2. Using the Base Station Your addIT base station consists of the receiver (A720B), the power supply (A720PS), and addVANTAGE Lite software. Note: If you are using the addIT RTU as part of an A730 system, Opening the packages You get several boxes when you purchase the addIT base station.

    CHAPTER 2 Using the Base Station Installing the base station Installing the receiver Make sure you’ve received all the equipment and read through the instructions that follow. When you’re sure you understand them, you’re ready to install your base station. The following considerations are important to installation: •...

  • Page 13: Chapter 3. Using The Rtu

    Chapter 3. Using the RTU Remember that the addIT A720/A723 remote telemetry units (RTUs) can be used either with the A730 system or as standalone systems with the A720B base station. The base station is discussed in “Using the Base Station” on page 9.

    CHAPTER 3 Using the RTU More about the LED tool This completes the installation of your addIT RTU. If one of the connectors is left unused, use the cap specially provided to protect it against moisture and dust. Be sure to make a note of the follow- ing information because you’ll need it when you configure the device in the software: •...

    The sur- rounding vegetation can also lower the panels’ efficiency. Note: The same type of battery is used in the A720/A723 and A720B devices, so the information in this section also applies to the A720B.
  • Page 19 If you have verified that the battery needs to be replaced, follow these steps to do so: Open the lid by unscrewing the four screws in the corner of the addIT RTU. Gently remove the lid (the battery is fixed on the lid and is connected to the electronics board by means of a connector).

    Device series Understanding connectors The receiver connector Currently, two A720 device versions are in use: Series 1 and Series 2. in addition, since begin of 2001, Adcon introduced also the Series 3 model (A723). You can determine which series a device is in any of these ways: The VER command (see pages 29 and 52).

  • Page 23: The Rtu Connectors

    Table 2. addIT Receiver Pin Functions The RTU connectors The addIT RTU uses standard 7-pin sensor I/O A and I/O B con- nectors (model Binder 702 and 712 series or equivalent) that are identical. Each connector contains 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).

  • Page 24: Configuring The Devices

    Note: To configure the A720B receiver, use the serial cable that comes with the system. To configure the A720 or A723 RTU, you must have the special adapter cable (available from Adcon) and plug it into the POWER connector.

  • Page 25: Serial Communication Protocol

    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 combi- nation.
