POWER SOURCE
THIS PRODUCT SHALL BE POWERED BY A LISTED CLASS 2 POWER SUPPLY ONLY.
Power to the unit must be within the specifications listed. A 24VAC center tap transformer rated
at 400mA is required. In the USA and in Canada an American Fibertek PS-24CT-T is supplied
with this unit.
POWER CONNECTION
Power is supplied to the unit via a three pin Phoenix connector. The ground wire from the center
tap supply must be connected to the center pin of the Phoenix connector. When installed
properly, the nominal voltage measured from the center pin to either of the outside pins will be
12 volts AC and the nominal voltage measured from one outside pin to the other outside pin will
be 24 volts AC.
INPUT / OUTPUT CONNECTIONS
The fiber optic connection is made via a ST connector located on the left side of the unit.
Video output connections are located on the right side of the unit. A BNC connector is provided
for each channel. The 75
Ω video outputs can be looped through typical baseband video inputs
of switchers, recorders and other equipment as required. For proper operation, the outputs must
be terminated with 75
Ω. For optimum performance the video cables should be the shortest
length of coax practical.
