American Fibertek MR-91P088SL - Manual (Page 3)

POWER CONNECTION
Power is supplied to the unit via a two pin terminal connector on the right side of the unit. Follow the label on unit
for proper orientation of +12 volt dc and ground.
FIBER INPUT / OUTPUT CONNECTION
The fiber optic input / output connection is made via a FC/PC connector located on the right side of the unit.
VIDEO OUTPUT CONNECTION
The video output connection is made via a BNC connector on the right side of the unit. The 75
Ω video output can
be looped through typical baseband video inputs of switchers, recorders and other equipment as required. For
proper operation, the output must be terminated with 75
Ω. For optimum performance the video cables should be
the shortest length of coax practical.
AUDIO INPUT / OUTPUT CONNECTIONS
Audio input and output connections are made via a terminal block on the right side of the unit. Follow the label on
unit for proper orientation of input and output connections. Please note that the far right pin on the label (DATA
OUT-) corresponds with the terminal block pin located closest to the base of the unit.
MR-91P088SL STATUS INDICATORS
The MR-91P088SL receiver provides the following LED status indicators to aid in installation and troubleshooting:
AUDIO TX
A green LED indicator is provided to monitor the audio coming in from the electrical interface, through the MR-
91P088SL, and out onto the fiber. The intensity of this indicator will vary with input audio levels, however in typical
applications it will cycle on and off as audio is transmitted. Audio transmission status associated with this LED is
summarized below.
AUDIO TX LED Audio Status
Green Audio Present at Proper Signal Level
Off Audio Signal Not Detected
AUDIO RX
A green LED indicator is provided to monitor the audio coming in from the fiber, through the MR-91P088SL, and
out onto the electrical interface. The intensity of this indicator will vary with input audio levels, however in typical
applications it will cycle on and off as audio is received. Audio received status associated with this LED is
summarized below.
