3 DESCRIPTION

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),
electromagnetic interference (EMI), and cross talk because
the video carrier is infrared light, and is transmitted
through a nonconductive fiber optic cable. Interference­free 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
enclosure or in a modular style package that can be rack­mounted using an optional EIA 19" compatible rack unit.

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.

4.6 LTC 4628, LTC 4629 Series Modules
for Video + Bosch Biphase Control
Code Transmission

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.

4.7 LTC 4671 Series Modules for

System4 / Allegiant Keyboard
Transmission

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.

A termination resistor is typically required when a
module is connected to the following controller
devices:

• Allegiant LTC 8100 Series main CPU bays

• Allegiant LTC 8200 Series main CPU bays

• Allegiant LTC 8300 Series main CPU bays

• Allegiant LTC 8900 Series main CPU bays

• LTC 8714 Series Allegiant Keyboard Expander

accessory units sold prior to 2002

• LTC 2604 Series Multiplexer Keyboard

Expander

A termination resistor is typically NOT required when
a module is connected to the following controller
devices:

• Allegiant LTC 8500 Series main CPU bays

• Allegiant LTC 8600 Series main CPU bays

• Allegiant LTC 8800 Series main CPU bays

• LTC 8714 Series Allegiant Keyboard Expander

accessory units sold during or after 2002

If the supplied resistor is damaged or lost, any locally
obtained conventional 1/4 watt carbon resistor
between 120 ohm and 390 ohm should suffice.

2. The POWER LED will light when AC power is
applied to the unit.

3. The DATA XTMR LED will flash as the external
data received by the unit is being optically
transmitted.

4. The DATA REC LED will flash as optical data is
being received by the unit.

4.9 LTC 4637 Series Rack-mount
Card Cage

4.9.1 Installation

1. Install the LTC 4637 Series Rack-mount into a

standard EIA 19in. rack, using user-supplied rack­mounting hardware. Be careful to not damage
exposed objects on the back of the card cage unit.

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.

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.

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.

6. Refer to the sections of this manual for specific

installation instructions regarding the plug-in
modules.

4.9.2 Indicators

1. LTC 4637 Series front panel LED illuminates when

AC power is applied to the unit.

2. Each fiber optic plug-in module is equipped with a

POWER LED indicator that illuminates when
power is applied to the rack unit.

4.9.3 LTC 4637 Maintenance / Service

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.

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.

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:

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.

c) Reverse the above procedure to install the power

supply into the card cage.
