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:  
Individual LTC 4600 or LTC 4700 Series  
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

connector on the rear of the card engages the  
3-pin connector on the back plane.  
2. Install the appropriate mounting screws (not  
supplied) into the keyhole locations. Allow  
sufficient leeway under the screw head for the  
module to be mounted.  
Each fiber optic plug-in module is equipped  
with a power LED indicator that illuminates  
when power is applied to the rack unit.  
For the LTC 4641 Series Video Transmitter, a  
single mounting hole is provided to secure the  
module.  
3. Fasten the module into place by tightening the front  
panel captive screws into the appropriate mating  
holes with a small flat blade screwdriver.  
3. For modules other than the LTC 4641 Series,  
position the module over screw heads, slide to one  
side, and then tighten screws.  
4. Connect the applicable video and/or data  
connections to the appropriate connectors, located  
either on the front or rear of the module. Refer to  
the example diagrams later in the individual  
sections.  
4. Connect the cable from the supplied power supply  
to the power input terminals on the module.

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.

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.

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.
