Iââ¬â¢m thinking of buying a GSM4(3G) module, or may be rhe 2G version.
I have a spare UCM, can I use that rather than buying the whole UCM-GSM unit?
Also is the GSM4(3G) available on its own.
Thanks
The GSM has its own UCM board if I remeber rightly
You can buy the GSM submodule
but the UCM Firmware for GSM is diferent from the firmware for the regular UCM, so you cannot plug in a GSM onto a normal UCM baseboard
The UCM firmware uses the Comfort protocol while the uCM/GSM firmware talks to the GSM module using AT commands
Thanks. So does that mean I can use my existing UCM with different firmware then?
Sorry I must have given the wrong explanation
No you cannot use the UCM and plug in the GSM submoduleThe UCM/GSM has a different firmware from UCM/USB/ETH

Ah ok so the firmware is NOT user changeable then?
You can upgrading firmware on the UCM only to the same Type, eg GSM to GSM, USB/ETH to USB/ETH. It is not possible to upgrade firmware to a different type
Thanks for the clarification.
