The dip switches are used to set the channel and to set relay output type. The dip switches can be
accessed by removing the module from the rail (see Section 3.9 for details on how to remove the
modules from the rail). After removing the RF/CPU module from the din rail, press in the tabs to release
the PCB from the housing (see Section 3.9 for details) and set the dip switches as necessary for the Flex
M system utilized (refer to the project drawings for any specifics). There are no wires to attach to the
RF/CPU module aside from either an antenna or a coaxial cable on the TNC antenna connection.
For channel dip switch settings for each of the different RF types, refer to the appropriate table in Section
