CommLink 5 Technical Guide
CommLink 5 Overview
The ASM01874 CommLink 5 is used to transfer communications
between controllers or local loops on your control system. It can also
be used as an interface for connection of a computer to your system.
The CommLink 5 provides communication with the control system
through any computer that is running Prism 2 software. For remote
communications, an IP Module Kit can be installed for LAN and
Internet connections.
Optional IP Module Kit
The ASM01902 IP Module Kit, when installed and confi gured in
the CommLink 5 communication interface, provides TCP IP Inter-
net and/or intranet connection for Ethernet networked computer
systems, allowing them to communicate with your control system.
The IP Module Kit consists of the IP Module and a 10 ft. long CAT5
Ethernet crossover cable.
Using standard TCP/IP Protocol, with AAON’s Prism 2 software, you
are able to monitor and confi gure your controllers without a modem
or a direct connection from a PC. Utilizing existing routers, proxies,
or fi rewalls allows a PC running Prism 2 to connect to a controller
in a remote accessible location or building. Several IP connection
profi les can be created to facilitate monitoring several CommLink
5’s with IP Module Kits installed on individual sites.
Installing the CommLink 5 ONLY
When you are using the CommLink 5 in an application without a
computer or IP Module, follow
Steps 1-3
in the Quick Guide on

.
WARNING:
If you are replacing an earlier version of the Com-
mLink with a CommLink 5, be aware that the R(+) and T(-)
terminals on the communications terminal block are reversed
from all previous models of the CommLink. You must always
confi rm that the polarity is correct when wiring 24 VAC power
to the CommLink power terminal block or serious damage to
the product will result.
