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
page 4.
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.

Connecting the Network
Figure 4: Example Network Diagram of a Firewall or Proxy Confi guration
Proxy and Firewall Compatibility
Proxy and Firewall configurations may become necessary
when the CommLink 5 is connected to a LAN/WAN that is pro-
tected by a commercially available Firewall, Proxy, or NAT enabled
router. Examples of these would include Cisco, NetGear, LinkSys,
or WatchGuard Technologies. Also, some ISPs provide IP Address
ranges that are already fi re-walled at the NOC or ISP Head-End.
Make sure that your IT Department or ISP can create a mapped TCP
port 39288 on your fi rewall/proxy to TCP port 39288 on the assigned
IP Address of the CommLink 5.
Only with proper confi guration of the Firewall/Proxy are connections
to the CommLink 5 from outside of the local area network going to
be possible. Check that the Firewall/Proxy TCP port 39288 is not
set to time out or reset after a specifi ed amount of time when there
is no traffi c from the remote PC.
