XStream‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v5.x00 [2006.02.24]
4.1. Automatic DIP Switch Configurations
Each time the RF Modem is powered-on, intelligence on the XIB-R Interface Board (RS-232/485
interfacing board located inside the RF Modem) sends AT Commands that program the RF Modem
based on positions of the DIP Switch. Automatic configurations that take place during the power-
on sequence affect stored RF Modem parameter values as shown in the tables below.
Figure 4.1. RF Modem DIP Switch
Table 4.1. RF Modem Power‐up Options (J7 jumper and Config Switch)
Condition
If J7 is populated
If Config Switch is pressed
If J7 is NOT populated and Config Switch
is NOT pressed
Table 4.2. AT Commands Sent as result of DIP Switch Settings (SW = DIP Switch)
Condition
Restore Default Parameter Values of the RF Modem
If SW1 & SW2 are ON (up)
Serial Interfacing Options
If SW1 is ON (up)
If SW1 is OFF (down)
Parity Options
If SW5 & SW6 are OFF (down)
If SW5 is OFF (down) & SW6 is ON (up)
If SW5 is ON (up) & SW6 is OFF (down)
If SW5 is ON (up) & SW6 is ON (up)
Exit AT Command Mode
Always
IMPORTANT: 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 the J7 jumper of
the XIB-R Interface Board. By default, J7 is not populated.
Behavior
Processor is disabled and AT Commands are not sent to the RF Modem
