7 PG8-INTERCOM-FX and PG4-INTERCOM-FX User Guide
2 Device Description
The PG8/PG4-INTERCOM-FX series was developed in cooperation with some of the world’s leading manufacturers
of intercom systems and are fully compatible with Clear-Com or RTS intercom matrixes, user key-panels and
interfaces.
The PG8/PG4-INTERCOM-FX can be ordered with different quantity and types of inputs and outputs.
For Clear-Com intercom systems:
PG8-INTERCOM-CC-FX with 8Clear-Com compatible four-wire intercom ports with serial control.
PG4-INTERCOM-CC-FX with 4Clear-Com compatible four-wire intercom ports with serial control.
For RTS intercom systems:
PG8-INTERCOM-485-FX with 8RTS compatible four-wire intercom ports with serial control.
PG4-INTERCOM-485-FX with 4RTS compatible four-wire intercom ports with serial control.
For systems requiring line level I/O and GPIO:
PG8-INTERCOM-444-FX with 8Line Level inputs and outputs, 8GPIO and an auxiliary power output.
PG4-INTERCOM-444-FX with 4Line Level inputs and outputs, 4GPIO and an auxiliary power output.
The IC422 and IC485 provide four-wire intercom ports with line level audio inputs and outputs along with serial data
links on RJ45 connectors for communication between intercom matrixes and auxiliary devices.
Serial control is routed with the audio, requiring audio to be routed to and from each port in order to establish bi-
directional audio and serial communication between matrixes, user key-panels and/or interfaces.
Each IC422 and IC485 four-wire intercom port can be used as an independently routed line level input / output using
an adaptor from RJ45 to a connector such as XLR.
The IC422 and IC485 RJ45 four-wire intercom ports are duplicated with reversed wiring so that either matrixes (TO
MATRIX) or intercom key-panels (TO PANELS) can be connected to the unit using standard CAT cables, making
cabling simple and cost-efficient.
The PG-INTERCOM-444-FX provides line level audio inputs and outputs, GPIO (General Purpose Inputs and
Outputs) and auxiliary +5V DC and +12V DC power outputs, to power external circuits, on 37 pin D-Sub connectors.
GPIOs are routed with the corresponding audio inputs and outputs, requiring audio to be routed to and from each
port in order to establish bi-directional audio and GPIO link.
What do the product names refer to?
PG4 and PG8 refer to the channel capacity of the device.
FX specifies that the device is equipped with Optocore fibre connectivity.
CC/485/444: specifies the connectivity option of the device. The CC configuration
contains IC422 module(s), the 485 is equipped with IC485 module(s), and the 444 is
built with IC444 module(s).
