Page 31: If-Then Behaviour Statements
8. IF-THEN BEHAVIOUR 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 32 If the “Stay on” call option is selected, the GSM Commander will hold the call until the caller ends the call.
- Page 33 8.1.4. IF Output This trigger condition is very similar to “IF Input”, as it monitors and output instead of an input. 8.1.5. IF Logic Expression A statement containing this IF condition, will trigger if the specified logic conditions are met. This allows the user to specify interesting combinations, like input 1 AND input 2 must be active before action is taken.
- Page 34 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.

Do you have a question about the GC0321 and is the answer not in the manual?
Questions and answers
Commander sends high temp readings, probes are placed in liquid in fridges. temps readings are above 800 degrees Celsius
The GSM Commander GC0321 may be showing high temperature readings above 800°C when probes are placed in liquid in fridges due to incorrect scaling or misinterpretation of the analog signal. The document states that a 20mA output signal corresponds to 94°C. If the software is not correctly configured to interpret the signal within the expected range, it may display extreme values. Adjusting the temperature reading conversion in the Setup Software may resolve this issue.
