2.2. Firmware Updating
The RV-D80-EB/RV-M80-EB is a software based radio and modem. There are times an
existing unit needs to get updated with a new feature, and this can often be done by
loading the new firmware into the older radio modem. In firmware program called the “Boot
Loader” is permanently installed inside the RV-D80-EB/RV-M80-EB ’s microcontroller.
During power up, it checks to see if the user wants to update the application program in the
microcontroller.
