Radio Communication Module (RCM)
InSight Adapter
Carefully pull the RCM away from the Breakout Board.
Plug the InSight Port cable into the InSight Adapter.
Plug one end of the InSight Port cable into the 10 pin InSight Port (J31) on the Breakout Board, and the
other end into the ISA. If desired, the InSight Port cable may be connected directly to the RCM instead of
the Breakout Board, but the Breakout Board connector allows for straight cable paths and more convenient
swapping of modules.
Verify that the InSight Adapter’s Target Power Select switch is set to Int (Internal).
Unplug the InSight Port cable from the Breakout Board (or radio communication module).
Unplug the InSight Port cable from the InSight Adapter.
Hardware Connections
Connecting the Breakout Board and RCM
Observe electrostatic discharge (ESD) precautions when removing, handling, or replacing RF
