Step 2: Select "Device Manager". This will open the device manager window as below:
Double Click on "Universal Serial Bus(USB) controllers"
In the list of USB controllers, you should see an item called "GSM Commander".
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 [ALL APPS] > GSM Commander V7 > Reinstall drivers) . This
will install your drivers.
20.3. GSM Commander does not send any SMS messages / Error codes
Cause 1: Airtime / network problem
The airtime on your SIM card may be depleted, or the SIM card may have been de-activated by the
network. Refer to Section 5.4 (SIM Card)
Cause 2: Reception problem
You may have bad reception in your area, preventing the unit from connecting to the network.
Please check using a regular cellular phone that there shows 1-2 bars of signal right next to the GSM
Commander. Refer to Section 5.5 (Antenna).
Cause 3: Bad configuration
You may have configured the unit incorrectly. Please send a status request message to the unit, and
see if it responds (Section 5.17). If it does respond, the unit is operating correctly.
Here is a list of error messages you might see under "Stuff happening right now" on the Status
page of the SmartSetup software:
SMS Problem 187
This means that the internal GSM module failed not respond while trying to send the SMS. This could
be a network or hardware issue.
SMS Err 189, retry. (Could be airtime?):X
This means that the internal GSM module reported and error while trying to send the SMS.
In most cases the error is related due to the airtime being depleted. "X" is the number of attempts.
After 5 failed attempts, the GSM Commander will restart the GSM module.
SMS Err 190, retry...
This means that the internal GSM module failed to respond during another point in the SMS sending
process

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.
