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 100 to 240 VAC, 50 to
60 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 FC/PC connector located on 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. Please note that video channels one, two, and five through eight are not used in this
unit. The video inputs are connected to an appropriate 75
Ω
baseband video source such as a camera
or a video recorder output. 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.
MRT-820C-SL STATUS INDICATORS
The MRT-820C-SL transmitter provides the following front panel LED status indicators to aid in
installation and troubleshooting:
VIDEO
A bi-color LED indicator is provided for each of the two video channel inputs. Please note that video
channels one, two, and five through eight are not used in this unit. AC power and video status
associated with each of these LEDs are summarized below.
