  • Page 6: Installation

    Please Note: While the GSM Commander has fairly rugged internal power supply circuitry, no special provision for lightning protection is made. If the GSM Commander is used in an area that is prone to thunderstorms, it is advisable to use a commercially available lightning suppressor (The same applies to inputs or outputs that are connected to wires longer than 2 or 3 meters).

  • Page 7: Antenna

    1-2 bars of signal. If the signal is too weak, the GSM Commander may have trouble sending or receiving SMS messages. In these cases, try and find a better location, or order one of our special antennas.

  • Page 8: Optically - Isolated Digital Inputs

    5.8. Optically - Isolated Digital Inputs The GSM Commander itself provides 2 signal inputs. The number of inputs can be expanded by the addition of Expansion modules, up to a maximum of 32 inputs (depending on type). Each of these inputs have 4 terminals associated with them: –...
  • Page 9 The + and – terminals are internally connected to the input power supply of the GSM Commander via a fuse and a diode. These terminals are provided to make it easy to connect dry contacts to the GSM Commander.

  • Page 10: Outputs

    5.9. Outputs The GSM Commander itself provides 2 x 8A (DC) Relay outputs. The number of outputs can be expanded by the addition of Expansion modules, up to a maximum of 32 outputs (depending on type). Each of these inputs each have 3 terminals associated with them:.

  • Page 11: Temperature Sensor

    5.10. Temperature Sensor One can connect 2 temperature sensors to the GSM Commander (at the expansion port via a temperature interface module) to measure temperature and allow the GSM commander to perform certain tasks if the temperature falls above or below a certain point. The sensor provides an accuracy of 2°C.

  • Page 12: Battery Input

    The output of the circuit above feeds to an Analog-to-Digital converter with a reference voltage of 0.98V, and a resolution of 8 bits. The full-scale input voltage to the GSM Commander is therefore 10.8V. The range of the analog input can easily be increased by the addition of a resistor in series with the analog input.

  • Page 13: Expansion Unit

    In cases where the GSM Commander is used in conjunction with a large system with its own battery (such as UPS systems), the battery terminals of the GSM Commander can be safely connected to the large (12V) battery, and the GSM Commander can then monitor the battery voltage for you (only while power is NOT supplied to the power input connector).
  • Page 14 10way ribbon cable (labelled IN and OUT). Typically the ribbon cable used when the expansion unit is installed next to the GSM Commander. If you have more than one expansion unit, you can daisy chain them using ribbon cables connected to the IN and OUT terminals as shown, or you can just connect them in parallel using the screw terminals as shown.
  • Page 15 Expansion Connection (continued) You are also able to use a combination of ribbon cable and screw terminal connections. This is ideal if you are planning to have one expansion unit next to the GSM Commander and another installed remotely. © Polygon Technologies. All rights reserved...
  • Page 16 ONLY. DIP setting The DIP setting on each expansion unit will determine where in the IO space of the GSM Commander, the expanded inputs and outputs will be mapped. The switches are labelled 1,2,3,4 on the switch itself, and 1,2,4,8 shown on the PCB. Please ignore the 1,2,3,4 on the switch.
  • Page 17 DIP Settings (continued) Here is a legend to show how other expansions in the chain should be set up (the maximum number of inputs and outputs supported, is model dependant) Expansion Unit Power Each Expansion unit has both a 12V DC jack and battery input, so that it could also be powered by a separate power supply and battery.

    5.14. Dimensions of Expansion Unit 5.15. Status LEDs The GSM Commander has 2 LEDs to show the current status of the GSM Commander. The red LED, labeled “GSM”, shows the status of the internal GSM cellular engine, while the green LED, labeled “STATUS”, shows the status of the GSM Commander as a whole.

  • Page 26: Override Gprs Settings

    7.8. Override GPRS Settings This set of commands allows you to override the GPRS settings that the GSM Commander may have been configured with and can only be sent from the administrator number. These override settings are non-volatile, which means their effect will remain after power has been cycled.

  • Page 27: If-Then Behaviour Statements

    8. IF-THEN B EHAVIOUR STATEMENTS The GSM Commander is configured by defining a number of behaviour statements. Each statement takes the form of an IF-THEN pair. You are thus able to select certain trigger conditions that will cause desired actions to be performed. Any combination of IF and THEN parts can be assembled into complete statements using the configuration software.
  • Page 28 If the “Stay on” call option is selected, the GSM Commander will hold the call until the caller ends the call.
  • Page 29 requirements. The user can choose between the following two options: Check if Above Threshold Check if Below Threshold Thus, if the user chooses “Check if Above Threshold”, then as soon as the specified variable goes above the specified threshold, the statement will trigger. The same applies to the other option, provided it's condition is met.
  • Page 30 Please Note: To use this option, you need to have a temperature probe connected to the expansion port of the GSM Commander via a temperature interface module. Also make sure that the correct type of probe is selected in the “Temperature Probe Configuration” box under the “Settings” tab in the software.
  • Page 31 The GSM Commander will check the prepaid airtime balance from time to time, and the statement will trigger if the balance is below the selected threshold.

  • Page 32: Supported Then Actions

    8.1.17. IF GSM Signal Strength A statement containing this IF condition, will trigger as soon as GSM signal strength meets the specified requirements. The user can choose between the following two options: Above X Below X Thus, if the user chooses “Below X”, then as soon as the GSM signal strength goes below the specified threshold, the statement will trigger.

  • Page 35: Multiple Actions To A Single If Condition

    SMS as well. The GSM Commander will always execute all statements that are eligible to trigger due to a certain event, in other words, the first statement that is triggered, does not void or “eat up” the event.

  • Page 36: Variables

    If you are using any “Variable” Modbus Expansion units with Your GSM Commander, these variables are populated with information collected via Modbus. The modbus address of these expansion units will determine which of the 16 variables are populated.

  • Page 37: Timed Operations

    The GSM Commander can also be configured to trigger a statement at a certain time on a certain date or group of days.

  • Page 40 (in this case, an input becoming active). Note that the voice call will not “say” anything when the call is answered. One will typically use Caller ID to identify the GSM commander number, and this will be enough to let you know that there is something wrong at home.
  • Page 41 We use a second GSM commander unit at the remote location. Here we connect the warning light to output 1 of the GSM Commander so that if the relay is activated, the warning light will turn on. (exactly as described in section 6.9) Remote GSM Commander configuration: The configuration of the remote unit will be similar to example 2 (control an appliance).

  • Page 42: Troubleshooting

  • Page 43 If this item is not present, the drivers are not installed correctly. To install your drivers, go to C:\Program Files\GSM Commander V7\drivers\drv_install and run “GSMC_USBXpressInstaller.exe or run “Reinstall drivers” (Start > All Programs > GSM Commander V7 > Reinstall drivers) . This will install your drivers.
