4.2.8.2 Watchdog at Multiboard operation
If there are multiple boards like 425, 1625,
1650 etc. used in a PC, the Watchdog cables
have to connected in a row from board to
board.
(J2
è
J1 etc.)
4.2.8.3 75 Ohm terminate resistor
Video terminals like video boards,
monitors, multiplexer etc. are applied
with a 75 ohm terminator. If a camera
should be connected to two terminals
like video board and monitor, you
have to use a BNC-T adapter.
To avoid stressing the camera output
amplifier, the termination of the
middle terminal has to be switched
off.
This can be done by pulling out of
the corresponding jumper on the
video boards.
4.2.8.4 Connecting an analog video monitor
Above the BNC connectors on the video board is a Cinch socket (yellow) available to connect an external analog
video monitor. Analog signals in live-mode can be sent to the analog monitor if the corresponding settings in the
software are set. Be aware, that only signals from direct connected cameras to the video board can be displayed
on the analog monitor. Multiboard operation requires multiple monitors, respective a "Quad Video Processor",
because it's not allowed to connect the video outputs together for simultaneously displaying of the signals.
4.2.8.5 Connection audio
All video boards contain - according to the type of the video board - one to four mono audio inputs. The boards
425 and 1625 contain a audio jacket for a 3.5mm jack plug for microphone or line-mono signals. The boards
1650 and 16100 are connected over the audio extension board.
The input sensitivity can be justified in a wide range. (see also: Configuration audio )
The video board supplies a phantom potential of 2V for operating capacitor microphones.
