Chapter 1. Introduction This manual explains the hardware aspects of Adcon’s A724 Series 4 addSWITCH remote telemetry units, including installation issues and certain parameter configurations. The manual has the following chapters: • • • • Introduction, which gives some general information and document conventions. Using the addSWITCH, which details the installation and use of the remote telemetry unit.
CHAPTER 1 Conventions 6.2 Volt rechargeable battery, which is charged either by a solar panel or an external power adapter. A special configuration can be implemented where no internal battery is used, rather the power is obtained exclusively over an external connector. The A724 is a ruggedized unit, complying to the IP65 environmental protection class (NEMA 4). You can easily install and integrate the unit into an Adcon A733 network.
Chapter 2. Using the addSWITCH The A724 Series 4 addSWITCH remote telemetry unit (RTU) is part of the A7xx series. For testing purposes, you should have an A840 or A850 Telemetry Gateway including the A440 Wireless Modem installed before you install the A724 Series 4 RTU. For information about installing the A840 or A850, refer to the device’s user’s guide. Opening the packages The addSWITCH RTU package contains the A724 Series 4 RTU, a valve connector cable, and a ring clamp.
CHAPTER 2 Installing the RTU Figure 1 shows the front view of an addSWITCH RTU. GORE PREVENTTM VALVE CONNECTOR ANALOG ANDCOUNTER INPUTS TO SOLAR PANEL Figure 1. addSWITCH RTU Note: If you turn or manipulate the Gore Prevent element, the unit’s IP65 environmental protection could be affected. Installing the RTU The following restrictions apply: • • In general, the typical “line-of sight” distance the RTU can communicate is 1 km (0.6 miles).
CHAPTER 2 Installing the RTU Field Installation It is relatively easy to install RTUs in the field. You can perform a connectivity check with an LED tool, an example of which is shown in Figure 2. Figure 2. LED Tool Note: The LED tool is a blind plug to be connected to the POWER connector. Follow these steps to install Adcon’s RTU in the field: 1. 2. 3. 4. 5. Note: Review the installation area and choose the best site. Perform a connectivity check using the LED tool: a.
CHAPTER 2 Installing the RTU This completes the installation of your addSWITCH RTU. If one of the I/O connectors is left unused, use the cap 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 of each RTU and location Type of sensors connected to which port of each RTU More about the LED tool The LED tool allows you to rapidly check the status of an RTU.
CHAPTER 2 Maintaining and servicing the RTU To configure the addSWITCH RTU in your A840 or A850 Telemetry Gateway and addVANTAGE Pro, please check the respective user guide. Maintaining and servicing the RTU A Series 4 RTU 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.
CHAPTER 2 Maintaining and servicing the RTU 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 frequently check and clean your solar panels. Rain and dust can cover the solar panel’s surface with a thin layer of dirt, effectively reducing its power output. Surrounding vegetation can also lower panel efficiency.
CHAPTER 2 Maintaining and servicing the RTU Figure 4. Unplugging the PCB Connector 3. Unscrew the two nuts of the plastic cover that holds the battery pack in place, then remove the cover. Figure 5 shows the battery pack inside the RTU. Figure 5. Battery Pack 4. WARNING Remove the battery pack and replace it with a new one (obtainable from Adcon). 5. Replace the plastic cover and fasten the two nuts. 6. Insert the battery plug into the PCB connector.
CHAPTER 2 Maintaining and servicing the RTU 8. Screw the four cover screws back in, applying a moderate force.
Chapter 3. Performing Advanced Functions With the appropriate knowledge, you can configure addSWITCH devices in the field by using a hyperterminal window. To configure the RTU, you will need a special serial cable adapter (not supplied, but available from your Adcon distributor). CAUTION Do not try to configure your RTUs if you are not sure what to do—the unit might not communicate with the remote measuring station or function with the addVANTAGE software.
CHAPTER 3 Understanding connectors connector contains four pulse counter inputs, one analog input, and a sensor supply voltage output. Figure 6 illustrates the individual pins of an I/O connector.

Connect the positive terminals (commonly red) of the valve to the corresponding Valve1-4 pins and the negative terminals (commonly black) to the COM pins. WARNING Be sure to check the cabling, otherwise one or more valves will switch to ON state when the RTU enters misery mode or upon a reset of the RTU. Table 2.
CHAPTER 3 Communicating with the RTU Communicating with the RTU You can use a Windows Hyperterminal window to connect to the addSWITCH RTU. After you have installed the system, follow these steps to configure the device and set the default parameters: Note: To configure the A724 Series 4 RTU, you must have a special adapter cable (item number 200.720.540 from your Adcon distributor) and plug it into the POWER connector. 1. 2. 3. 4. 5. Note: Open a Hyperterminal window.
CHAPTER 3 Upgrading the Firmware In bootloader mode, the command line interface’s prompt is the character >. Therefore, to reboot the RTU just type the following after you see the > prompt: reboot An alternative way to boot the RTU is to disconnect the battery and after a few seconds reconnect it. For a list of the available commands, type Help at the > prompt. Available commands: upgrade [baudrate] ... upgrade from Y-modem download version ... show the version of the bootloader state ...
CHAPTER 3 Upgrading the Firmware you will work within a Windows HyperTerminal window on your computer. Before upgrading the firmware, you must reboot the RTU to access the bootloader mode’s command line interface. Follow the procedure described under Booting the RTU to get into the bootloader. Before you start the upgrade, it is very important that you copy the firmware image to the hard drive of the computer you use in the field. You also need to know which version of the bootloader you are running.
CHAPTER 3 Upgrading the Firmware Figure 12. Hyperterminal and Com Port Properties Dialogs 5. 6. 7. 8. In the Bits per second field, select 115200. Select OK in the com port’s Properties dialog to close it. Select OK in the hyperterminal’s Properties dialog to close it. Back in the hyperterminal window, press Enter to continue the upgrade. --------------------------------------------------The current firmware image must be erased for the upload.
CHAPTER 3 Serial communication protocol 10. From the hyperterminal window’s menu bar, select Transfer Send File to display the dialog shown in Figure 13. Note: You must start the image upload within 60 seconds or a timeout will occur. Figure 13. Dialog to Upload Firmware Image 11. Browse to and select the firmware image. 12. Select the Ymodem Protocol and click Send. 13.
CHAPTER 3 Using terminal commands • Param1 Param2 ... ParamN represent the parameters, which are command dependent.
