About this Guide

This installation guide explains how to install the RS-422 / RS-485 Distribution Panel. The ADAC422DP includes an external power module.

About the Product

The RS-422 / RS-485 Distribution Panel:

• Provides signal amplification for American Dynamics RS-422 / RS-485 dome-control communication.

• Has 16 output ports to accommodate home-run dome wiring or multiple daisy-chained links to domes, J-boxes, or other distribution panels.

Each port has an LED that indicates received data, and a line status test switch with LED.

• Is designed to be wall-mounted or installed in a 483mm (19in) EIA / IEC equipment rack.

Rack Installation

1. Secure the distribution panel to the equipment rack.

2. For proper surge protection, attach the panel to a grounded rack or connect a conductor from the panel to ground using hardware provided. Ensure metal-to-metal contact.

Wall Installation

1. At the rear of the distribution panel, measure from key slot to key slot to determine screw/anchor locations. Then install suitable screws and anchors (not supplied) in the wall to which the panel is to attach. The wall and hardware must support 5.1kg (11.2 lbs).

2. Attach the panel to the pre-mounted screws. Then lock the panel in place by inserting a third screw into the wall centered adjacent to its top surface.

3. For proper surge protection, connect a conductor from the enclosure to ground using hardware provided. Ensure metal-to-metal contact.
