Replacing Cinterion MC35i with TRB142

Hello. We are replacing our simple Cinterion MC35i 2G modes with TRB142 units. We are looking for settings to make this work. The old models were easy, connect the 9pin RS232 connector, power and antenna and go.
Any help would be appreciated. And yes, we tried to insert the sim and connect cables but no communication. LEDs indicated 4G connection.


For Quick Start Guide, please refer to our wiki page here.

If you want to access the modem via RS232, please take a look at the modem control information here.

In case you need more information on how to perform operations on the modem, please refer to GSMCTL and AT command articles here and here, respectively.

Kind Regards,

Thanks. Will try this!
