Reactiviating a Raven XT cellular modem may help resolve communication for a 3100-iSIC modem that can be powered up but is nonresponsive.
1. Unplug the serial DB-9 connector from the iSIC and connect it to an A77 programming cable provided with the data logger. Connect the other end of the programming cable to the computer.
