The Cloud Paging Interface Buss must be correctly terminated at each end to prevent
communication problems. The factory default settings for the CDPM configure the unit to
terminate the buss correctly. This means that intermediate microphones (those with both an ‘IN’
and ‘OUT’ connection) will need to be reconfigured to not terminate the buss. For these
microphones, internal jumper J4 should be set to the OFF position (i.e. no link between the pins).

On the 36/50, 46/50, CX263 and CX163 mixer sections, the Microphone 1 input can be used as
either a general purpose microphone (default) or as a paging microphone. In order for the
microphone input to be used as a paging microphone, the access contacts on the rear panel
should be enabled using the appropriate jumpers. The table below shows the appropriate
jumpers for each of these units, and the corresponding diagram shows the jumper location inside
the unit.
