Power Source; Power Connection; Input / Output Connections - American Fibertek MTX-8885 Instruction Manual

For mounting the unit flush to a wall or other
rigid surface, the ears may be installed on the
sides with the oval holes flush with the bottom of
the unit as in Figure 2. Mount the ears with the
#10 flathead screws provided. Mount the
unit to a rigid surface using #10 (5mm) screws.

POWER SOURCE

The internal power supply accepts universal line voltage. Any mains supply from (85 to
264 VAC), (47 to 63 Hz) may be used without modification or adjustment. A universal
power connector is provided on the rear of the unit to facilitate connection to the power
mains.

POWER CONNECTION

The unit is supplied (in the US and UK only) with a three conductor power cord. The
"ground" conductor is directly connected to the chassis.

INPUT / OUTPUT CONNECTIONS

The fiber optic connection is made via a ST connector located at the back of the unit. Be
sure to allow sufficient room for the required minimum bend radius of the fiber cable
used.
Video input and output connections are located on the rear of the unit. A BNC connector
is provided for each channel. The video inputs are connected to an appropriate 75Ω
baseband video source such as a camera or a video recorder output. The 75Ω 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
75Ω. For optimum performance the video cables should be the shortest length of coax
practical.
Data input and output connections are located on the rear panel terminal block. A mating
plug connector is provided. The figure below identifies the specific connections for the
RS485 data connections. See next page for RS422 / RS232 data connections.
