2.3.1 Connecting the DCN system

The transmitter requires the DCN Interface Module (LBB 3423) to interface with the Digital Congress Network (DCN). This

module must be mounted in the transmitter housing (see section 2.2.2).

The connections between DCN units and the transmitter are made in a loop-through configuration via the DCN 6-pole circular

connectors on the module’s rear panel. See the DCN Installation and Operating Manual for more information.
