POWER SUPPLY CONNECTIONS
The OSD361 requires external DC or AC power. The acceptable DC voltage range is +9 to +18V DC,
and the allowed AC voltage range is 6 to 15V AC, with maximum current draw of 100mA. Power
should be connected to the 2 way socket located at the back of the case. Take care to connect DC
power with the correct polarity: Pin 2 is ground and Pin 1 is positive power. For AC supplies the
polarity is not applicable.

SIGNAL CONNECTIONS
Video input signal should be connected to the female BNC connector on the OSD361 using 75
Ω
cable
terminated in a male BNC connector.
The optical fiber cable must be terminated with the appropriate optical connector. Before connection,
inspect the ends of the connectors to ensure that no dust or dirt is present as it could contaminate the
modem connector and result in poor performance.
If it is necessary to clean the cable connectors use isopropyl alcohol and lint free tissue to remove
contamination.

INDICATOR
The OSD361 has one LED indicator. The indicator will be ‘green’ to indicate that power to the unit is
“on”.
