Communication module cable
You use the CM adapter cable to connect the communication modules (e.g. RF180C and ASM
456) to the optical reader. The communication module cable is pre-fabricated.
Note that when using the power supply via the communication module, you must enable the
setting "Settings > Options > Lighting > Power supply via POU or CM".
