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 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 input connections are located on the right side of the unit. A BNC connector is provided
for each channel. The video inputs are connected to an appropriate 75
Ω baseband video
source such as a camera or a video recorder output. For optimum performance the video cables
should be the shortest length of coax practical.
