FVTRD
10-BIT DIGITAL BI-DIRECTIONAL VIDEO OR VIDEO SYNC
+ BI-DIRECTIONAL DATA
The FVTRD(M)(S)1 supports simultaneous transmission of short-haul quality
10-bit bi-directional digital video or video sync plus bi-directional data over one
multimode or single mode optical fiber. The module is universally compatible
with major CCTV camera manufacturers and supports RS232, RS422 and 2 or
4-wire RS485 data interfaces, and most major data protocols. Plug-and-play
design ensures ease of installation and no electrical or optical adjustments
are ever required. Bi-color (Red/Green) LED indicators are provided for rapidly
ascertaining equipment operating status. These units are interchangeable
between stand-alone or card mount configurations. See Figure A on Page 5
for installation instructions.
Each Data Channel is configured for the electrical interface by means of the
“DATA SELECT” switch on the front panel. Figure 4 on Page 3 illustrates the
switch settings to set the type of data for each channel.
Figure 5 on Page 4 illustrates the specific data connections for RS232, 2-Wire
RS485 and RS422/4-Wire RS485. (This last data connection also applies to
Manchester & Bi-Phase data transmission.) It also illustrates the electrical
connections between the “Customer Equipment” and the FVTRD.
See Figures 1 – 5 for complete installation details.

MECHANICAL INSTALLATION INSTRUCTIONS
INSTALLATION CONSIDERATIONS
This fiber-optic link is supplied as a Standalone/Rack module. Units
should be installed in dry locations protected from extremes of
temperature and humidity.
STANDALONE MODULE:
The unit is provided with a mounting plate with holes for two No. 6
pan head screws (3 mm or 3.55 mm). Attach the module to a solid
piece of wood using two No. 6 pan head wood screws with a
minimum penetration into the wood of 3/4 inch. (Screws not
supplied). See Figure A.
RACK MODULE:
The unit is designed to be installed in the ComNet 19-inch (483-mm)
EIA standard card-cage rack, the C1-US, C1-EU, or the C1-CH. Follow
these guidelines to install rack cards after performing module setup
procedures.
C1-US, C1-EU, C1-AU OR C1-CH CARD CAGE RACKS
CAUTION: Although the units are hot-swappable and may be installed
without turning power off to the rack, ComNet recommends that
the power supply be turned off and that the rack power supply
is disconnected from any power source. Note: Remove electrical
connector before installing in card cage rack.
FIGURE A
Dimensions are for a standard ComNet™ one slot module
.156 [3.96 mm]
.313 [7.95 mm]
1. Make sure that the card is oriented right side up, and slide it into
the card guides in the rack until the edge connector at the back
of the card seats in the corresponding slot in the rack’s connector
panel. Seating may require thumb pressure on the top and bottom
of the card’s front panel.
CAUTION: Take care not to press on any of the LEDs.
2. Tighten the two thumb screws on the card until the front panel of
the card is seated against the front of the rack.
WARNING: Unit is to be used with a Listed Class 2 or LPS power supply rated 9-12 VDC @ 1A.
WARNING: This unit should be installed in a restricted access location; available through the use of a lock and key or other means of security. Access should
be limited to service personnel who have been instructed about the reasons for the restrictions to the location. Any and all precautions should be taken and
controlled by the authority responsible for the location.
IMPORTANT SAFEGUARDS:
A) Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be
greater than room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient
temperature (Tma) specified by the manufacturer.
B) Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not
compromised.
