4. RF Modem Configuration
4.1. Automatic DIP Switch Configurations
Each time the RF modem is powered-on, AT commands are sent to the on-board module as dic-
tated by the positions of the DIP switches. DIP switch configurations are sent automatically during
the power-on sequence and affect modem parameter values as shown in the table below.
Figure 4‐01. RF Modem DIP Switches
Table 4‐01. Power‐up Options ‐ Commands sent as result of DIP Switch Settings (SW = DIP Switch)
IMPORTANT: To avoid overwriting previously stored custom configurations (due to the automatic con-
figurations that take place each time the RF modem is powered-on), it is necessary to disable a pro-
cessor located inside the modem.
To disable the processor, turn switches 5 and 6 ON (up). When switches 5 and 6 are ON, only the
CS command is sent [refer to table below].
Table 4‐02. User Defined Mode (Switches 5 and 6 are ON (up))
Note: The results of SW 2, 5 & 6 ON and SW 5 & 6 ON are the same.
