3.4. Automatic DIP Switch Configurations
Each time the RF Modem is powered-on, intelligence on the Max-
Stream Interface Board (located inside the RF Modem) sends AT
Commands that program the modem based on positions of the DIP
Switch. Automatic configurations that take place during the power-on
sequence affect RF Modem parameter values as shown below.
To avoid overwriting previously stored custom configurations (due to the automatic configurations
that take place each time the RF Modem is powered-on), it is necessary to disable a processor
located on the XIB-R interface board. To disable the processor, populate J7 of the XIB-R Interface
Board. (By default, J7 jumper is not populated.)
