DESCRIPTION
This electronic equipment should be unpacked and
handled carefully. In addition to a copy of these
instructions, check for the following items:
The LTC 4600 and LTC 4700 Series are transmission
systems that provide efficient, high quality video and data
transmission via multimode fiber optic cable for improved
CCTV system performance. Signals are immune to
ground loops, radio frequency interference (RFI),
1. Stand-alone units:
•

Module, and associated Power Supply
electromagnetic interference (EMI), and cross talk because
the video carrier is infrared light, and is transmitted
through a nonconductive fiber optic cable. Interference-
free operation ensures reliable service. Unlike microwave,
wire, and coaxial cable transmission systems, fiber optic
transmission is difficult, if not impossible, to tap. And,
since fiber optic cable is nonconductive and does not
radiate a signal, it is difficult to detect and locate. These
compact devices are available in a surface mount

4.5.2 Indicators / Operation
4.5 LTC 4630, LTC 4631, Series Modules
for Bilinx Video/Data Transmissions
1. The POWER LED illuminates when AC power
is applied to the unit.
4.5.1 Important Considerations
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.
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.
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.
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.

4.6.1 Indicators / Operation
1. The POWER LED illuminates when AC power is
applied to the unit.
2. LTC 4628/60, LTC 4628/50, and LTC 4628/00
units: The VIDEO PRESENT LED illuminates
GREEN when a valid video signal is present, or
RED if no video is being received. The DATA
RECEIVE LED illuminates RED when no data is
received, and flashes YELLOW as data is received.
3. LTC 4629/60, LTC 4629/50, and LTC 4629/00
units: The VIDEO OUT LED illuminates GREEN
when a valid video signal is present on the
LTC 4628 Series Transmitter, or RED if no video is
present. The DATA IN LED illuminates RED if no
data is being received on the optical signal, and
flashes YELLOW as data is received.
4.6.2 Optional Connection
Because of signal amplitude variations and possible
EMI/RFI noise interference in the Biphase control data
line, the pan/tilt device may operate erratically or
intermittently when first connected. If this is the case,
add the supplied 120 ohm termination resistor across
the data connections of the LTC 4629 fiber optic
module located at the controller site.
If the supplied resistor is damaged or lost, any locally
obtained conventional 1/4 watt carbon resistor
between 100 and 120 ohms will suffice.

1. The supplied 120 ohm resistor must be installed
across the external data connections when these
fiber optic modules are used with certain controller
devices. Follow the guidelines below, however,
because of differences between the hardware of
new and old controller units, these cases are not
absolute. If a configuration does not work when
first connected without using a termination resistor,
try adding the termination resistor across the data
connections of the fiber optic module located at the
controller site.

4.9
LTC 4637 Series Rack-mount
Card Cage
Information
1. The power supply is fused with a 1A slow blow
fuse. To replace the fuse, remove the AC power
line cord from the power supply, and carefully pry
out the fuse module above the AC connector.
4.9.1 Installation
1. Install the LTC 4637 Series Rack-mount into a
standard EIA 19in. rack, using user-supplied rack-
mounting hardware. Be careful to not damage
exposed objects on the back of the card cage unit.
2. The 3-pin connector on the rack supplies a 20VAC
center tapped voltage, and is the only electrical
connection from the back plane to a plug-in
module. Each plug-in module contains its own
fuse, so in the unlikely event of a module failure,
the other modules in the rack remain unaffected.
2. If a secondary earth ground connection is needed, a
grounded wire with a ground lug can be attached to
the rack using the protruding screw provided on
the right side of the chassis.
3. Connect the supplied AC voltage line cord between
the rear of the power supply and the appropriate
AC voltage source.
3. The power supply is modular in construction, and
can be replaced in the event of damage or failure.
To remove the power supply from the rack:
4. Fiber optic plug-in modules can be installed into
any of the available 14 slots of the card cage. Most
modules require only a single slot width, but others,
such as the LTC 4644 and LTC 4645 Series,
require two slot widths.
a) Disconnect the AC line cord and power supply
cable from the circuit board back plane, located
on the rear of the card cage.
b) Loosen the four (4) screws located at the front of
the power supply using a small flat blade
screwdriver. Slide the power supply out of
the card cage.
5. If desired, LTC 4600/00 blank panels (ordered
separately) may be installed to cover unused slots.
A single blank panel covers a single slot opening.
c) Reverse the above procedure to install the power
supply into the card cage.
6. Refer to the sections of this manual for specific
installation instructions regarding the plug-in
modules.
