4.4. 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)
