4.5 LTC 4630, LTC 4631, Series Modules
for Bilinx Video/Data Transmissions
4.5.1 Important Considerations
1. To ensure proper Bilinx communications, the
video output of the LTC 4631 Series module
must be terminated into a proper 75 ohm load.
If improper video looping connections are used,
erratic or no camera P/T/Z control may result.
2. Do not exceed the published distance
specification for Bilinx communications. Erratic
or no camera P/T/Z control may result. Refer to
the data sheet for product specifications.
3. Although these modules are compatible with
Bilinx up-the-coax communication technology
found in Bosch Security System products,
compatibility is not guaranteed when used with
similar technologies employed by other
manufacturers.

4.5.2 Indicators / Operation
1. The POWER LED illuminates when AC power
is applied to the unit.
2. LTC 4631 Series units: Once the video signal
and fiber optic connections have been
completed, the state of the VIDEO OUT and
AGC LED indicators should be examined. If
both are GREEN, test the VIDEO OUT LED
action by temporarily removing the video signal
from the LTC 4630 module. The LED should
turn RED.
If necessary, adjust the AGC control in small
increments until the correct LED actions are
obtained. Marginal signal strengths are indicated
by an AMBER color LED, and a RED LED
indicates video loss, or that further adjustments
are needed. The adjustment is sensitive. Adjust
the control too high, and the VIDEO OUT
LED may remain lit even when the video signal
is removed or lost. If adjusted too low, the
VIDEO OUT LED may remain RED even if a
video signal is present.
