The PG-Intercom are 1RU digital intercom audio and data control I/O interface devices for the ProGrid Signal Transport Solution featuring the Optocore™ Optical and SANE™ CAT5 Digital Network technologies.
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 RJ45 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. The devices can be used as a generic networked audio line level input and output converter. Devices include dual power supplies with automatic switchover.
Network
Redundant fiber connections can be established using the two provided Optocore Optical LINK interfaces. All PG-Intercom devices are equipped with either single-mode or multi-mode SFP fiber transceivers. Depending on the selected transceivers, distances from 2300ft (700m) up to 43.5mi (70km) can be covered. The dual redundant ring structure provides maximum safety in a network with low latency. Four RS485 ports allow the transport of a wide range of serial data standards, such as RS422, DMX and MIDI. In addition to the audio signals, video and data signals are transmitted by the fiber connection.
SANE
Each PG-Intercom panel is equipped with two SANE ports, which enables send and receive of up to 56/64 audio channels via standard CAT5 cable. Use the SANE ports to expand the number of inputs and outputs on ProGrid FX devices. SANE ports can also be used to send Ethernet data. In addition, PG-Intercom devices have two separate LAN ports for 100BaseT Ethernet transmission.
Word Clock
Optocore technology uses synchronous transmission, allowing extremely low-jitter Word Clock transportation together with audio and video. All ProGrid devices are equipped with a Word Clock IN and OUT to enable the synchronization of the devices to an external source and are used to pass on the Word Clock from one device to the next. For stand-alone applications, the devices are equipped with an internal Word Clock.
