The AUDIO / RS232 over IP PoE Transceiver is an extender that allows 2CH audio signals to be extended via Cat5e/6 cable in a point-to-point configuration. Point-to-multipoint and multipoint-to-multipoint is supported by connecting several Transceivers to the same local Ethernet network. The device supports PoE (PD) if used with a PoE (PSE) Ethernet Switch, and RS232 and IR transmission.
