Chapter 1. Introduction This manual explains the hardware aspects of Adcon’s addIT™ A723 Series 4, including installation issues and certain parameter configurations. The manual is divided into these chapters: • "Introduction," which gives some general information and document conventions. • "Using the Base Station," which details the installation and use of the receiving unit. • "Using the RTU," which details the installation and use of the remote telemetry unit.
CHAPTER 1 Introduction The addIT A723 Series 4 RTU can be used in one of the following way: • Installed in the vicinity of an Adcon remote measuring station (A72x, A73x, A74x), the addIT RTU can use the A73x and A74x stations to relay its data to a base station (A840 or A850). If the base station is close enough to the addIT RTU, the RTU can communicate directly with the base station.
CHAPTER 1 Conventions Conventions Certain conventions apply in this documentation. Italics Indicate the text is variable and must be substituted for something specific, as indicated in the explanation. Italics can also be used to emphasize words as words or letters as letters. Bold Indicates special emphasis of the text. Also indicates menu names and items in a window. fixed font Indicates characters you must type or system messages. File Indicates menu selection.
CHAPTER 1 Introduction
Chapter 2. Using the RTU Remember that the addIT A723 Series 3 remote telemetry unit (RTU) can be used either with the A73x and A74x system or as a standalone system with the A440 Radio Modem and the A840 or A850 base station. Opening the packages You get several boxes when you purchase an addIT RTU.
CHAPTER 2 Using the RTU Figure 1 shows an addIT RTU. PROTECTIV E CAP TO SOLAR PANEL SERIAL NUMBER TO SENSORS Figure 1. addIT RTU Installing the RTU Installing addIT RTUs in the field is a fairly simple process. You’ll perform a connectivity check with an LED tool which is available from your Adcon Telemetry Distributor. Note: The LED tool is a blind plug to be plugged in the POWER connector. Follow these steps to install an addIT RTU in the field: 1.
CHAPTER 2 Installing the RTU on your application. Put a plastic cap on top of the rod to protect it. 4. Using a ring clamp, fasten the solar panel onto the aluminum rod. Ensure that the panel is facing south (north if you are located in the southern hemisphere) and out of the way of the addIT RTU. Note: The solar panel can be mounted under or behind the addIT RTU, but be sure that the RTU does not shadow the panel. 5. Fasten the addIT RTU to the top of the rod using another ring clamp.
CHAPTER 2 Using the RTU This completes the installation of your addIT 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 • Type of sensors connected to each RTU More about the LED tool The LED tool allows you to rapidly check the status of an addIT RTU.
CHAPTER 2 Maintaining and servicing the RTU be fully charged after two consecutive sunny days, but you should get an LED light-up after several minutes of charging in the sunlight. Configuring an addIT RTU in the A840/A850 Configurator If you’re using an addIT RTU with an A73x or A74x system, you can configure the RTU by following the steps described in the A840/ A850 Base Station User Guide. Maintaining and servicing the RTU The A723 Series 4 unit needs virtually no maintenance.
CHAPTER 2 Using the RTU Table 1 shows the addIT devices’ expected operation time on a fully charged battery with 50 mA total consumption for the sensors, as described above. Table 1.
CHAPTER 2 Maintaining and servicing the RTU 4. Remove the battery pack from the lid (it is taped to the lid) and replace it with a new one (obtainable from Adcon). 5. Insert the battery plug into the PCB connector. 6. Mount the lid back, taking care that the rubber gasket sealing the box is not out of place. WARNING Be sure to mount the rubber gasket properly, so that the unit’s IP65 environmental protection is not affected. 7. Screw the four screws back in, applying a moderate force.
CHAPTER 2 Using the RTU
Chapter 3. Performing Advanced Functions With the appropriate knowledge, you can configure the addIT 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). CAUTION Do not try to configure your addIT 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.
CHAPTER 3 Performing Advanced Functions Device series Currently, two A723 device versions are in use: Series 3 and Series 4. You can determine which series a device is in any of these ways: • The TYPE command. When the device is connected, you can type this command to the series. With a Series 3 device, the command returns TYPE A723 , while with a Series 4 device, the return is TYPE A723 Series 4. This is the most reliable method of determining which series you have.
CHAPTER 3 Configuring the devices If you have a special passive extender cable, you can use it to plug more than one sensor to one connector. CAUTION To avoid cabling conflicts, first verify in the A840/A850 Configurator software that the sensor combination in the configuration you want is allowed. If there are no conflicts, you can physically attach the sensors to the addIT RTU. addIT RTUs can also be used to control actuators and to switch on or off pumps, valves, or other similar devices.
CHAPTER 3 Performing Advanced Functions • No parity • No flow control • Send LF after CR 4. Select OK to open the terminal window. 5. Press Enter to generate a response in the window. 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.
CHAPTER 3 Using terminal commands 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.

CHAPTER 3 Performing Advanced Functions 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 will store the notification and wait until it is questioned by the host. At this point, it will inform the host that it has a notification. It is then the task of the host to issue a command to read the respective notification.
