Q-28
THE WORLD LEADER IN LOSS PREVENTION
What to do.
If the monitor is a dedicated (full time)
monitor, remove the looping video and set the
termination switch to 75 ohms.
If that does not correct the problem, isolate
the ground lug on the monitor power cord
using a 2-cond extension cord. DO NOT cut or
damage the line cord. If isolation of the
ground lug corrects the problem, order and
install a ground loop transformer (isolation
transformer).
If the video coming in directly from the dome
is poor, set the switches on the RS422
interface board to LL, SW5 on S1.
If the video coming in directly from the dome
is good, but the customer monitor video is
poor, check monitor, cabling, and connectors
for improper connections.
NOTE: Keep at least 1.5m (5') from high
voltage lines, flourescent lights, neon lights,
etc. when installing video and data cables. If
you must cross a 110Vac line, do so at right
angles to the cable.
NOTE: Use a quality coaxial cable (Beldon
8241 or equivalent).
