PACKAGE CONTENTS
This package contains:
One each FT-FOTR-1VD-ST-S 1-channel baseband video transmitter and receiver
Two 5VDC power supplies
One installation manual
PRODUCT DESCRIPTION
The FT- FOTR-1VD-ST-S fiber optic transmitter/receiver supports the transmission of a single
baseband video channel and a reverse data signal over one strand of single-mode fiber optic cable.
This product is compatible with all NTSC and PAL video signals. Power, optical signal, video signal
and data signal are easily inspected through LED indicators directly on the units. The transmitter
and receiver combination supports transmission distances for optical loss budgets of less than 18
dB.

INSTALLATION AND OPERATION
CAUTION: To reduce the risk of electrical shock do not remove the cover or back of this
unit. No user serviceable parts are inside.
CAUTION: To prevent electric shocks and risk of fire hazards, do not use other than
specified power source.
1. UNPACKING and HANDLING
Each unit is shipped assembled and factory tested.
Ensure that all accessories are removed from the container before discarding packing material
2. MECHANICAL INSPECTION
Inspect the front and rear of the equipment for shipping damage. Make sure the equipment is
clean, and no connectors are broken, damaged, or loose. If equipment appears to be damaged
or defective please contact your distributor or Fibertronix at 1-610-429-1511 for assistance.

A: Data Output +
B: Data Output –
G: Ground Connection
a. Plug the included power supplies in a 120VAC outlet. Each power supply’s DC output
adaptor connects respectively to the power input of the transmitter and receiver.
b. Connect the transmitter and receiver’s optical connectors with an ST/PC patch cable.
The transmitter and receiver’s Link Indicator Lights will indicate optical signals are
transmitted and received normally.
c. Connect the video source (e.g., camera) to the transmitter’s video input port using
quality 75Ω coaxial cable with BNC connectors.
d. Connect the video monitor to the receiver’s video output port using quality 75Ω coaxial
cable with BNC connectors.
e. Connect the data ports the RS485 terminal block. Be sure the wiring configurations are
consistent with the diagram above for the transmitter and receiver as well as the PTZ
camera.
f. Indicator lights:
Power LEDs display power status. A normal display indicates the input
power supply is correct. An irregular display indicates the wrong input power
or a problem with the unit’s circuits.
Link LEDs display whether the optical signals are being transmitted and
received correctly.
Video LEDs indicate whether the video signals are being transmitted and
received correctly.
Data LEDs display whether data communications are working correctly.
4. SPECIAL ATTENTION
a. Only use the power supplies included with these units. The use of other power supplies
may damage the transmitter and/or receiver and void the warranty.
b. The loss of optical fiber should be less than 18 dB. Any loss greater than 18 dB will
compromise the receiver’s ability to get the optical signals from the transmitter.
c. Adhere to the equipment’s in-door operating temperature and humidity specifications.
Failure to do so may damage the equipment and void the warranty.

5. TROUBLESHOOTING
a. No picture after applying power –(i) check all connectors and cables are securely
connected to the video source, monitor, transmitter and receiver; (ii) ensure all power
supplies are providing the correct voltage and current.
b. No image or poor image quality –determine if the optical signal loss is greater than 18
dB.
c. The picture has ripples –(i) check to see if the camera’s power supply is experiencing
AC ripple, if so a filter may be required; (ii) determine if the monitor is faulty; (iii)
determine if other peripheral equipment is causing ripple and if so make the necessary
adjustments.
d. The picture background continuously changes color –a fluorescent lamp’s magnetic
field may cause color roll, therefore, reduce the number of fluorescent lamps or
increase the distance between the camera and the lamps.
e. The picture appears smeared –(i) the camera’s power supply voltage level may be
unstable, therefore, try another power supply; (ii) ensure the camera and/or monitor
cables are correctly connected and/or the cables are of the correct impedance.
f. Other interference may require a Fibertronix ground loop isolation filter.
g. Data communications are not working –(i) ensure all cables and connectors are
secured and (ii) all terminal block connections are consistent as specified in the wiring
diagram for the transmitter and receiver and the PTZ camera.
