CONNECTIONS
a. The CT-FSAM550 is designed for installation in a standard 19” EIA rack.
b. Connect a jumper cable between the
I.F. Output port
and the
I.F. Input port
if no
scrambling or EAS system is being used.
c. Connect a 75ohm coaxial cable with F-connectors from the
video source’s Audio
Output port to the CT-FSAM550’s Audio Input port.
d. Connect a 75ohm coaxial cable with F-connectors from the
video source’s Video
Output port to the CT-FSAM550’s Video Input port
.
e. Connect a 75ohm coaxial cable with F-connectors from the
CT-FSAM550’s RF
Output port to the headend combiner
.
f. Connect the CT-FSAM550 to an appropriate power source capable of powering this
device. Be certain that power source is capable of handling the load if the CT-
FSAM550 and other equipment are being powered by it. The use of a surge protector
is highly recommended. Product warranty does not cover surge damages.
