Rx
—
If the FOX HD-SDI is configured as a bidirectional
transceiver or as a receiver
,
for one-way communications
from the transmitting unit, connect a fiber optic cable to the
Optical Rx connector.
If the FOX HD-SDI is configured as a bidirectional transceiver
,
connect the free end of this fiber optic cable to the Optical Tx
connector on the transmitting FOX HD-SDI.
If the FOX HD-SDI is configured as a receiver
,
connect the
free end of this fiber optic cable to the Optical Tx connector
on the next FOX HD-SDI in the daisy chain.

Buffered Outputs connectors —
In any FOX HD-SDI
configuration
,
connect a digital display to these BNC
connectors. See "Transceiver configurations" on page 1-3 for
more details.
If the FOX HD-SDI is configured as a bidirectional transceiver
,
the video is output on both connectors 1 and 2 and is the video
signal sent from the other transceiver.
If the FOX HD-SDI is configured as a receiver
, the video
is output on connector 2 only and is the video sent by the
transmitting unit.
If the FOX HD-SDI is configured as a transmitter
, the video is
output on both connectors 1 and 2 and is looped through from
the same transceiver's HD/SDI Input connector, item

Power connector —
Plug the included external 12 VDC
power supply into this 2-pole captive screw connector.
See “Power supply wiring”, on the next page, to wire the
connector.

Power supply voltage polarity is critical. Incorrect
voltage polarity can damage the power supply
and the FOX HD-SDI. Identify the power cord
negative lead by the ridges on the side of the cord
(figure 2-10).
To verify the polarity before connection, plug in the power
supply with no load and check the output with a voltmeter.
W
The two power cord wires must be kept separate
while the power supply is plugged in. Remove
power before wiring.
C
The length of the exposed (stripped) copper wires
is important. The ideal length is
3/16" (5 mm)
.
Longer bare wires can short together. Shorter wires
are not as secure in the connectors and could be
pulled out.
N
Do not tin the power supply leads before installing them
in the connector. Tinned wires are not as secure in the
connectors and could be pulled out.
Use the supplied tie-wrap to strap the power cord to the
extended tail of the connector.
Alternatively, an optional Extron PS 123 Universal 12 VDC
Power Supply, part #
60-814-01
, can power multiple Extron
12 VDC devices using only one AC power connector.
