CHAPTER 2 Opening the packages Chapter 2. Using the addWAVE 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 device’s user’s guide.
CHAPTER 2 Installing the RTU Figure 1 shows the front view of an addWAVE RTU. Figure 1. addWAVE RTU (A753) Installing the RTU 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.
CHAPTER 2 Installing the RTU 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. 4. 5. Note: 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. Using a hammer, drive the 80 cm aluminum rod into the ground.
CHAPTER 2 Configuring an A753 in the Telemetry Gateway 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.
CHAPTER 2 Maintaining and servicing the RTU Maintaining and servicing the RTU 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.
CHAPTER 2 Maintaining and servicing the RTU Replacing 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 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 pack’s plug from the PCB connector, as shown in Figure 4. Figure 4.
CHAPTER 2 Maintaining and servicing the RTU 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 4. WARNING Remove the battery pack and replace it with a new one (obtainable from Adcon). 5. Put the plastic cover back into position and fasten the four screws. 6. Insert the battery plug into the PCB connector.
CHAPTER 3 Understanding Connectors Chapter 3. Performing Advanced Functions 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). CAUTION 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.
CHAPTER 3 Communicating with the RTU • • 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.
CHAPTER 3 Booting the A753 4. 5. 6. 7. 8. Note: Open a Hyperterminal or similar terminal application. Select the appropriate serial port and click OK.

CHAPTER 3 Using Terminal Commands • • 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.
