DESCRIPTION OF EQUIPMENT
Functional Characteristics
The VersiVision FVT1100 and FVR1100 Series Fiber Optic Video Modems are used to extend a
frequency modulation (FM) video signal and return data over a single
fiber optic cable. These modems
provide high quality transmission of one channel simplex video and one channel return data at distances to
3km using multimode fiber and distances to 30km using singlemode fiber. A BNC connector provides the
copper interface for the video input/output and a DB9 connector provides the copper interface for the data
input/output. RS-422, RS-485, and RS-232 data interfaces are supported. ST and SC optical connectors
are standard for the fiber optic interface. The FVT1100 and FVR1100 video modems are completely
compatible with NTSC, PAL, or SECAM video standards.

Page 5
VERSITRON FVT1100 and FVR1100 Series Fiber Optic Video Modems utilize APC circuitry
while maintaining stable optical power output. The fiber optic link established between the transmitter and
receiver devices insures immunity from EMI, RFI, and ground loops. AD, Pelco, Phillips, and Vicon
communication protocols are supported. The data interface is switch-selectable to assure compatibility
with cameras utilizing RS-422, RS-485, or RS-232 data protocols for their PTZ (pan, tilt, zoom) features.
The plug and play design of the FVT1100 transmitters and FVR1100 receivers means no user adjustments
are required. LED status indicators include video sync present (VD), data transmitted (TD), data received
(RD), and power on (PWR)
Physical Characteristics
The VersiVision FVT1100 transmitter and FVR1100 receiver modems are available as standalone
devices for easy plug and play installation. In addition, the FVR1100 receiver modems can be ordered as
circuit card modules (See Chart Above) for installation in the Model FVC14 rack-mount chassis. The
14-slot chassis fits in a standard 19” rack and is offered with either 110VAC or 220VAC power supplies.
The dimensions of the FVT1100 and FVR1100 standalone devices are 7.5in (L) x 6.3in (W) x 1.2in (H).

CAUTION!
The transmitter unit contains a light-emitting diode located in the optical connector. This device emits
invisible infrared electromagnetic radiation that can be harmful to human eyes. The radiation from this
optical connector, if viewed closely without any protection, may cause instantaneous damage to the retina
of the eye. Direct viewing of this LED should be avoided at all times.

INSTALLATION INSTRUCTIONS
FIGURE 2: PSACV1 Power Supply FIGURE 3: VCA1100 Data Cable
INSTALLATION PROCEDURE
The VersiVision FVT1100 and FVR1100 Series fiber optic video modems can be used with RS-485/RS-422
and RS-232 data protocols. Simply set the mode of operation with the internal DIP switches and then connect
the signal, power supply, and fiber optic cables between the two units. There are indicator LEDs on the units for
monitoring the real-time status of video, power, and data. The following instructions describe the typical
installation procedure and the function of the LED indicators located on each unit.
1. Connect the video source (camera) to the video input BNC connector on the FVT1100 transmitter unit
using coaxial cable.
2. Connect the video output BNC connector on the FVR1100 receiver unit to the video monitor using
coaxial cable.
3. Connect the fiber optic cable between the transmitter and receiver devices.
4. See page 8 for instructions on connecting the data cable
5. Apply the power supply to both the transmitter and receiver using the PSACV1 power supply provided.
Note: If using any of the FVR1100M modules, power is provided from the integral power supply of the
FVC14 chassis.
6. When the power is applied, the red POWER LED will light, indicating the presence of operating power.
The green VIDEO LED and the blue DATA LED will give an indication as stated in the following page.
7. The link should now be operational.

SYSTEM DIP SWITCH SETTINGS
The data interface circuit used in this product has internal switches that are used to configure the various signal
options. These are preset to RS-485 at the time of shipment. If changes are required, the positions of these
switches must be changed in accordance with the following table.
Protocol 1 2 3 4
RS-485/RS-422 On Off Not Used Off
RS-232 Off On Not Used Off
RS-485 Bus Matching Off Off Not Used On
*Note: RS-485 Bus Matching: When the switch is on, then 120 Ohm termination is applied which
matches the twisted pair cable impedance.

TROUBLESHOOTING
OPTICAL FIBER
The VersiVision FVT1100 and FVR1100 Series fiber optic video modems are available for applications using
multimode or singlemode optical fibers. Please be certain that the correct size and type of the fiber is being used
for the particular mode transmitter/receiver combination.
Also be certain that the attenuation and bandwidth of the fiber optic cable being used is within the range of the
system’s loss budget specifications.
GENERAL
Any dirt or dust may easily pollute or block the fiber from accepting or radiating light. Therefore, please try to
keep the optical connector clear and always use the dust caps whenever the connector is exposed to air. It is
suggested that the tip of the optical connector should be carefully cleaned with a lint-free cloth moistened with
alcohol from time to time.
The status of any of the VIDEO LED should provide the first clue as to the origin of any operational failure. If
the VIDEO LED on the receiver unit is off, it usually means that the fiber is broken or has too much attenuation.
Next, be certain to check all connections and assure that inputs and outputs are not intermixed and the
transmitter and receiver are not connected incorrectly.
DATA LINK
Even when installed exactly as directed, it is possible that the data function may fail to operate properly. If these
problems occur, first check the data cable, then check that the data cable connector is firmly inserted into the
data interface. Finally, swap the Red Wire (Transmit +) and Blue Wire (Transmit -) pins and then do the same
for the Red Wire (Receive +) and Blue Wire (Receive -) pins. Make sure to do this on both the transmitter and
receiver units.
RS-485 Pin Definition:
The RS-485(+) (Red Wire) should be connected to Pin 5 of the DB9F connector, while the RS-485(-) (Blue
Wire) should be connected to Pin 4 of the DB connector. (The pin numbers are embossed on the connector).
RS-232 Pin Definition:
The RS-232R (Green Wire) should be connected to Pin 1 of the DB9F connector while the RS-232T (Yellow
Wire) should be connected to Pin 2 of the DB connector, and the GROUND (Purple Wire) should be connected
to Pin 3 of the DB connector.
Note: If the system is still not working after examining the above possibilities, please contact our Customer
Service Department for further assistance.
