MODEL V707
CONNECTIONS
Video Cable Connection
Connect the video source cables to the four input BNC
jacks on the V707T transmitter. Connect monitor equipment
to the four output BNC jacks on the V707R receiver. See
Figures 2 and 3.
Vicon suggests that Belden number 9259 or equivalent
coaxial cable should be used.
Fiber Optic Cable Connection
Most cable manufacturers identify the individual fibers in
the cable. Select appropriately terminated fiber and mark
both ends with unique identification label (e.g., for cable no.
03, fiber no. 08) to ensure that the fiber connected to the
near end is the same one that is connected to the far end.
The proper optical connection links the transmitter's OUT
port to the receiver's IN port.
1. Wipe the inside of the port’s sleeve with a lint-free pipe
cleaner moistened with reagent-grade isopropyl alco-
hol. Blow dry with dry air.
2. Clean the connector using a lint-free cloth dampened
with alcohol to thoroughly wipe the side and end of the
ferrule. Blow the ferrule dry with dry air. Visually inspect
the ferrule for lint.
3. Fasten the fiber optic cable to the port.
Power Connections
Standalone modules may be powered either by 24 VAC or
by 13 - 16 VDC. Connect input power according to the
label on the module.
Rack modules’ power connections are made automatically
when the card is installed. To supply power to the rack,
connect the rack power supply to an AC outlet and set the
power switch to ON.
OPERATION
V707 links operate automatically once installed. For an
explanation of LED color codes, see pages 4 through 6
and Tables 2 and 3.
VIDEO TEST PATTERNS
The V707 includes an internal video test pattern generator
that can ease installation and troubleshooting. The test pat-
terns generated can notify the user of a fiber failure or a
video source failure by outputting specific test patterns on
the user’s monitor. This verifies proper functionality of the
digital decoding process as well as troubleshooting fiber
optic interconnections.
Follow the procedures described in VIDEO FORMAT/TEST
PATTERN GENERATOR on page 1 to enable the test pat-
tern generator.

displays that are available
LED OPERATION
The V707 has 3 LED indicators that are very useful in
describing the current state of operation, as well as the cur-
rent status of data flow and fiber optic signal strength.
These indicators are LEVEL/LOSS (Receiver) VIDEO IN
(Transmitter), VIDEO OUT (Receiver), and LASER
(Transmitter). Tables 2 and 3 provide a summary of LED
operation. See Figure 4.
They function as follows:
LEVEL/LOSS Indicator
This LED is useful for indicating the relative optical signal
strength at the fiber optic receiver. When sufficient optical
power is being received, the LED shines green. As the opti-
cal power is decreased, as happens through long fiber
runs, splices, or connections, the intensity of the
LEVEL/LOSS LED will diminish until the limit of the V707's
sensitivity range has been reached. At this point the LED
will be OFF. If any additional optical attenuation is intro-
duced, the LEVEL/LOSS LED will turn bright RED, indicat-
ing an insufficient amount of optical power is being
received.
VIDEO IN (and OUT) Indicator
The VIDEO IN LEDs indicate the strength of the four video
signals. The VIDEO IN LEDs on the transmitter remain
green as long as adequate video signals are being input to
the transmitter. If the video input becomes too weak on a
particular channel, the LED turns off. The VIDEO OUT
LEDs on the receiver perform a similar function, except that
