Quick Start Guide — FOX HD-SDI

  The FOX HD-SDI is a transceiver that can function as a 
transmitter and/or a receiver. At least two units are required 
for a transmitter-receiver system with at least one fiber optic 
cable linking each two units. The FOX HD-SDI is available in 
single mode or multimode versions.
Connect and operate two or more FOX HD-SDI units as follows:
Step 1
Power off all equipment. If desired, mount the units in racks.
Step 2
Use the rear panel 
Mode DIP switches 
to configure each 
unit to be installed 
in the system as 
a bidirectional 
transceiver, a transmitter, or a receiver as shown above right.

  The drawings below and on QS-2 show the signal flow for 
the three different FOX HD-SDI configurations. For more 
information on the various modes and their capabilities, see 
"Transceiver configurations" in chapter 1, "Introduction".
Step 3
Transmitting unit — Connect an HD-SDI, SDI, or 3G-SDI 
video source to the unit's HD/SDI In BNC connector.
Step 4
Transmitting unit — 
If the FOX HD-SDI 
is configured as a 
transmitter, and if desired, 
connect one or two local 
monitors to the unit's 
Buffered Outputs BNC 
connectors. These two 
BNCs output the same 
HD-SDI, SDI, or 3G-SDI video that was input in step 3.
Step 5
Both units — Connect 
a fiber cable between 
the transmitting unit's 
Optical Tx connector 
and the receiving unit's Optical Rx connector.
