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.)

Condition
Behavior
If J7 is populated
Processor is disabled and AT Commands are not sent to the RF Modem
If Config Switch is pressed
Processor is disabled and RF Modem enters into AT Command Mode
If J7 is NOT populated and Config
Switch is NOT pressed
Execute logic as shown in Table 6.
Condition
Behavior
Serial Interfacing Options
If SW1 is ON (up)
AT Commands sent: ATCS 0 (RS-232 Operation: CTS
function for CTS
line)
ATCD 2 (DO3 - RX LED = low)
If SW1 is OFF (down)
AT Commands sent: ATCS 3 (RS-485 or RS-422 Operation)
ATCD 2 (DO3 - RX LED = low)
Exit AT Command Mode
Always
AT Commands sent: ATCN (Exit AT Command Mode)
