Mounting
The OR-841-HDSDI is designed as a tabletop camera assist or tri-pod/camera-top monitor. It comes complete
with tabletop stand, easy-to-carry handle on top, and is equipped with both ¼-20 and 3/8” threaded mounts on
top and bottom. The included handle and stand may be removed for access to the threaded mounts.
There is an optional OR-8RK rack mount kit for mounting two OR-841-HDSDI units side by side in a standard
19” rack. When used in this configuration, the Dual OR-841-HDSDI units occupy 5 RU and have a +/- 40° Tilt.
Other optional accessories include the OR-8HO Custom Hood for daylight viewing and the OR-8HA optional
side mount handle. One handle may be mounted on each side of the OR-841 for easy carrying during a wireless
camera shoot.
Connections and Power-On
Plug the power supply into an AC power source (100-240 V @ 50/60 Hz). Attach the 4-pin female XLR
connector to the back of the monitor. The monitor will draw no more than 4.0 Amps at 12 Volts in operation
(24 Watts).
Connect the required cables for video signal input and output (Power must be applied to the OR-841-HDSDI for
the active loop-through outputs to be activated). All BNC connectors are rated at 75Ω.
