All PG-INTERCOM devices allow seamless integration of intercom audio and control data from Clear-Com and RTS/Telex intercom panels, interfaces and matrices. The PG-INTERCOM devices are available in two different hardware configurations, RS422 for Clear-Com and RS485 for RTS/Telex. The PG4-INTERCOM devices offer four RJ-45 4-wire intercom ports while the PG8-INTERCOM devices offer eight RJ-45 4-wire intercom ports. The RJ45 ports are duplicated with reverse wiring so that half the ports are wired for connection to intercom panels or interfaces and half the ports are wired for connection to the intercom matrices.
