VAV System
Description
The OE361-08 CommLink III Communi-
cations Interface allows computer access
into the WattMaster VAV controls system
and also provides communications across
multiple local communications loops on
the control system.
The CommLink III comes packaged in an
attractive beige colored plastic enclosure.
The CommLink III is powered by a small
wall mounted plug-in transformer that is
included. Locally, an optional on-site Per-
sonal Computer with Prism software in-
stalled may be connected to the
CommLink III to provide direct access to
system control parameters by using the
supplied USB cable (6 ft. long).
Remote telephone access to the control
system can be obtained via the optional
OE419-05 Modem Kit which can be field
installed inside the CommLink III Com-
munication Interface. With the optional
modem kit installed, the control system
can be accessed remotely by using a
Remote Link modem (purchased sepa-
rately) connected to a Personal Computer
with Prism software installed at the re-
mote location and dialing the phone num-
ber of the phone line the CommLink III
with modem kit is connected to. Also with
the modem kit installed the CommLink III
can be configured to call a pager or cell
phone number, if an alarm condition oc-
curs. A USB cable (6ft long) is provided
with the CommLink III for connection to
your computer.
Mounting
If an on-site computer is to be used for direct connection and monitoring of the system, the CommLink III should
be located near the computer terminal to monitor the system. If no on-site computer is to be used and/or you are
installing the optional modem kit, locate the CommLink III near the phone line jack for ease of connection.
