Mount and install PN1002-A1 - Installation - Mounting

The 'RS485 module (1 port)' PN1002-A1 provides an isolated 'PACE-Bus' (RS485) connection, an isolated 24 V with integrated ground fault detection, and connectors for isolated analog audio inputs and outputs.

One PN1002-A1 can be mounted on the Cerberus PACE Compact digital audio matrix board in the options area.

Mount the PN1002-A1 on position 'UI1' on the digital audio matrix board. Plug the PN1002-A1 to the connectors 'UI1-A' and 'UI1-B'. Fasten it with the 2 enclosed screws to the studs (marked in red circles)

Connect the analog audio input from the PN1002-A1 to the digital audio matrix board. Use an enclosed cable to connect 'UI1-C' (to intern 'Audio In') with the required analog audio input. See Install analog audio inputs.

If required to connect the analog audio output from the PN1002-A1 to the digital audio matrix board, use an enclosed cable to connect 'UI1-D' (from intern 'Audio Out') with the required analog audio output. See Install analog audio outputs.

An external call station can be connected via the single wire terminal 'CN1' on the front of the PN1002-A1 or via a RJ45 plug 'J4' on the rear.

Single wire connector - 'CN1'

In case twisted pair cables are used, ensure that corresponding signals are connected to the twisted pair wire, e.g. 24 Ｖ and GND, D- and D+ in the twisted pair wire.
