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.
