  • Page 5: Chapter 1. Introduction

    GSM/GPRS-based telemetry device with four digital I/O ports, twelve analog inputs, and four counter inputs. The A753 incorporates a GSM module and uses the standard GSM network for retrieving telemetry data (900/1800 MHz in Europe, 850/ 1900 MHz in the US).

  • Page 6: Conventions

    RTU. The maximum theoretical distance to a base station of your provider is approximately 35km, due to timing constraints of the GSM system. The A753 operates in conjunction with the A840 and A850 Telemetry Gateway only. Due to its construction as well as to the software controlling it, the power consumption is extremely low.

  • Page 7: Chapter 2. Using The Addwave

    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.

  • Page 8: Installing The Rtu

    Special Notes on GSM/GPRS Functionality  The A753 GSM/GPRS 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 a sufficient signal for proper operation of the RTU on the site where you plan to use it exists.

  • Page 9: Operating The A753

    You also need to insert that cellular provider's SIM card into the A753GSM/GPRS RTU’s SIM card holder by following these steps: Open the lid of the A753 by unscrewing the four bolt screws in the corners of the unit and removing the lid as shown in Figure 2.
  • Page 10 CHAPTER 2 Installing the RTU Locate the SIM card holder and open it by sliding it as indicated by the red arrow (see Figure 3). Figure 3. Open the SIM card holder Raise the holder top and slide the SIM card into it (see Figure 4). Figure 4.

  • Page 11: Activating The Sim Card

    To unlock the SIM, you will also need the PUK code, which is included in the SIM package you got from your provider. This completes the PIN entry procedure. After a few minutes of initialization you can check the status of the A753 at any time by...

  • Page 14: Configuring The A753 Connection Settings

    Adcon strongly recommends that you use professional router equipment. Configuring the A753 Connection Settings  Use the following commands to define the intervals the A753 will wake up and connect to the A850 Telemetry Gateway: GPRSCONNALIGN [align] Alignment of calls in seconds (default: 0, i.e. 00:00 = midnight).

  • Page 15: Field Installation

    08154711 Field Installation Installing a preset A753 in the field is a fairly simple process. By performing a connectivity check using an LED tool (not included in the delivery of a A753, but available from Adcon), you will be able to prove connectivity to the A850 gateway.

  • Page 16: More About The Led Tool

    Table 1 on page 17 describes the LED blinking codes for the A753. If the A753 is not connected to the A850, the unit flashes rapidly to let you know the unit is alive. These flashes occur every half second.

  • Page 17: The Rtu Battery

    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.
  • Page 18 Unscrew the four screws of the plastic cover that holds the battery pack in place, then remove the cover. Figure 8 shows this step, revealing the A753 battery pack inside the RTU. Figure 8. A753 Battery Pack Remove the battery pack and replace it with a new one (obtainable from Adcon).
  • Page 19 CHAPTER 2 Maintaining and servicing the RTU Mount the lid back, taking care that the rubber gasket sealing the box is correctly in place and free of dirt and soil. Screw the four cover screws back in, applying a moderate force.

  • Page 20: Chapter 3. Performing Advanced Functions

    In the system architecture, the base station and A753 are both considered to be nodes. The base station is called the master node, or master, while the A753 is called the slave node, or slave. The A753 includes a base station and a virtual RTU (maintaining only, no sensor data).

    500 mA. • RxD and TxD, which are used for serial communication (19200 baud) with the A753. The pinout of the SOLAR CELL connector is shown in Figure 9. Figure 9. The SOLAR CELL connector Note: Unlike the usual power connectors, the A753 SOLAR CELL connector features no external battery power supply.

    Booting the A753 Note: This section is included for informational purposes. You will rarely need to boot the A753. However, when you do need to do so, you will work within a Windows Hyperterminal window on your computer. Bootloader Mode When the A753 starts from a power-up reset (such as when you connect the battery to the unit), it enters the bootloader mode.

  • Page 23: Firmware Mode

    In bootloader mode, the command line interface’s prompt is the > character . Therefore, to reboot the A753 type the following after you see the > prompt: reboot An alternative way to boot the unit is to disconnect the battery and after a few seconds reconnect it.
  • Page 24 Windows HyperTerminal window on your computer. Before upgrading the firmware, you must reboot the A753 to access the bootloader mode’s command line interface. Follow the procedure described under Booting the A753 to get into the bootloader.
  • Page 25 WARNING When you continue with the upgrade process, any existing firmware image in the A753’s flash memory will be erased! You must supply a valid image for upload or the A753 will have only bootloader capabilities (that is, it will have no radio capabilities).
