Chapter 1. Introduction This manual explains the hardware aspects of Adcon’s A753 addWAVE GSM/GPRS Series 4 remote telemetry units, including installation issues and certain parameter configurations. The manual is divided as follows: • • • • Introduction, which gives some general information and document conventions. Using the addWAVE, which details the installation and use of the remote telemetry unit.
CHAPTER 1 Conventions install the 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. The unit operates off an internal 6.2 Volt rechargeable battery, which is charged either by a solar panel or an external power adapter.
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. CAUTION The A840/A850 Gateway must have a working internet connection and a fixed IP address that is accessible from the internet.
CHAPTER 2 Installing the RTU If ordered, the following items come in separate packaging: • • • solar panel with ring clamp set of aluminum poles LED tool Make sure you have received all the equipment and read through the instructions that follow. When you are sure you understand them, you are ready to install your RTU. Figure 1 shows the front view of an addWAVE RTU. Figure 1.
CHAPTER 2 Installing the RTU Operating the A753 The two ways to operate your A753 GSM/GPRS RTU are as follows: 1. 2. GSM mode: You must ensure that your provider offers CSD connections. Most cellular/GSM providers use a different telephone number for data communication than for voice communication. Don’t forget to ask for this data number when you order your SIM card, if you plan to use the RTU in GSM mode. When your modem calls the RTU from a land line, it must use the data number.
CHAPTER 2 Installing the RTU 2. 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 3. Raise the holder top and slide the SIM card into it (see Figure 4). Figure 4. Insert the SIM card into the holder 4. Snap the holder top back on and slide it back as shown again by the red arrow depicted in Figure 5. Figure 5. Close the SIM card holder 5.
CHAPTER 2 Installing the RTU 6. Put the four screws back in place, applying moderate force, tightening crosswise. Be sure not to overtighten the screws or leave them too loose. This completes the SIM-card installation. For additional information, please contact Adcon Telemetry or your local reseller of Adcon Telemetry products. Activating the SIM Card You need to activate the card by using a personal identification number (PIN).
CHAPTER 2 Installing the RTU entering the GSMSTAT command. This command returns a list of GSM parameters: # gsmstat 42395 gsmstat Power supply on: yes DTR on: yes DCD on: yes RI on: no RTS on: yes CTS on: no Modem on: yes Modem present: yes Modem initialized:yes SIM card present: yes PIN required: yes PIN accepted: yes PIN count: 3 PUK required: no GSM network: registered Operator: T-Mobile Austria Signal quality: 31 99 Phone call: no GPRS network: registered IP address: 10.11.12.13 TCP connection: 216.
CHAPTER 2 Installing the RTU To establish the data connection between the A850 and the A753, certain steps must be executed. These steps are split into two sections: CAUTION 1. Configuring the GPRS parameters 2. Configuring the TCP parameters Parameter values are case sensitive. Be sure to correctly spell the values of the GPRS parameters and use the appropriate case. Misspelled names/entries will cause the RTU to not connect to the GPRS network and/or A850.
CHAPTER 2 Installing the RTU GPRSDNS "[ipaddress]" where [ipaddress] is the DNS server address of your GPRS network operator (optional) Note: When using an Internet firewall in front of the LAN where the A850 Telemetry Gateway resides, be careful to properly configure the firewall and the GPRSCONNADDR parameters [a850-ipaddress] and [portnumber]. This is particularly important if you use NAT (network address translation) on your firewall.
CHAPTER 2 Installing the RTU Shared secret: 0 # 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. The LED tool is shown in Figure 6. Figure 6. 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.
CHAPTER 2 Configuring an A753 in the Telemetry Gateway This completes the installation of your A753. If the SOLAR CELL connector or the DC INPUT connector is left unused, use the cap provided to protect it against moisture and dust. Be sure to keep the following information in a place you can remember: • • Note: Serial number of the A753 (printed on the type plate) Location of the A753 This information will be necessary during the configuration of the device at the A850 Gateway.
CHAPTER 2 Maintaining and servicing the RTU The RTU battery • The internal battery supplies 6.2 volts and consists of a NiMH pack. The internal electronics manage the battery’s charging/ discharging process, ensuring it a long life time. This approach, coupled with a remarkably low average power consumption, allows an addWAVE RTU to operate at least two weeks on a fully charged battery, as long as the analog and the counter values are stored in the internal memory every 15 minutes.
CHAPTER 2 Maintaining and servicing the RTU 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 7. Figure 7. Unplugging the PCB Connector 3. 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 4.
CHAPTER 2 Maintaining and servicing the RTU 7. 8. 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.
Chapter 3. Performing Advanced Functions With the appropriate knowledge, you can configure A753 remote wireless modems 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 remote measuring station or function with the addVANTAGE software.
CHAPTER 3 Understanding Connectors The SOLAR CELL Connector The A753 remote wireless modem has a SOLAR CELL connector used to interact with the device. The connector features the following pins: CAUTION • Solar Input, which enables charging the internal batteries.
CHAPTER 3 Communicating with the RTU Communicating with the RTU You can use a Windows Hyperterminal window to connect to the A753 remote wireless modem. After you have installed the system, follow these steps to configure the device and set the default parameters: Note: To configure the A753, you must have a special adapter cable (item number 200.720.540 from your Adcon distributor) and plug it into the SOLAR CELL connector. 1. 2. 3. 4. 5. Note: Open a Hyperterminal window.
