How do I confirm my firmware revision on the GPS module?

The GPS modules do not come marked with the Firmware version. You can poll the software using Sirf Binary for the ISM300fx modules and use OSP (one Socket Protocol) for the ISM4xx version of gps modules.

If you want to run your GPS in Nema, you will need to switch to either Sirf Binary or OSP and send the module the message ID 132 – Poll Software version.
