2.2.3 POWER SUPPLY CONNECTIONS
The OSD840 requires external DC power. The voltage range of the OSD840 is +12V to +24V. This is
connected to the power socket located at the back of the case. DC power should be connected as
indicated in Table 4.
DC power in the OSD840 card version is connected via a DB9 connector. Power is supplied by the
chassis and should be fixed into the OSD370 chassis using the captivated screws. The card can be
plugged in or out of the OSD370 chassis with power on or off.

2.2.4 OTHER CONNECTIONS
The video-input signal (e.g. from camera) is connected to the video input BNC connector on the
OSD840T. The video output signal (e.g. to monitor) is connected from the video output BNC connector
on the OSD840R.
All Data, Audio and Relay signals are connected to the DB26 connector as set out in Table 3.
The 10/100 Base-T Ethernet signals are connected to the RJ45 connector on the rear of the unit. Figure
7 shows pin out configuration for the RJ45 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.
