VAV System
Description
The OE419-04 Remote Link is essen-
tially a 14,400 baud modem. The Re-
mote Link is used for achieving remote
communications with all WattMaster
VAV systems. Built in error correction
(V.42/mnp 2-4) and data compression
(V.42bis/mnp 5) will maximize data
transfer integrity and boost average
throughput up to 57.6 kbps. The Re-
mote Link connects to the CommLink II
communications interface at the Orion
control system location. A telephone line
connects the Remote Link to the local
phone service. By dialing the telephone
number that the Remote Link is con-
nected to, (using a modem from a re-
mote location) the Orion system can be
monitored and controlled using the
WattMaster Prism computer front end
software package.
Mounting
The Remote Link should be mounted
close to a serviceable telephone outlet.
It connects via a serial data cable to the
CommLink II communications interface
and via a telephone cable to the tele-
phone outlet jack. A molded cable for
connection from the CommLink to the
Remote Link is supplied with the
CommLink. If an on-site computer is re-
quired, it should be connected to the
CommLink at or near the location where
the Remote Link is located. If for any
reason you use cables of greater length
than those provided with the CommLink
II (6 ft. long) be sure the cables that
connect the CommLink II to the Remote
Link and the CommLink II to the on-site
computer do not exceed twenty-five feet
in length.
