5.4. Input and Output Circuits

5.4.1. Monitor video output

On the BNC connector an analogue video signal for set-up is found if OS=2. The signal can be used for focus and field of view adjust.

CCIR if MN=1. (50 fps, 17.734 kHz, 290 active lines.) EIA if MN=0. (60 fps, 17.734 kHz, 262 active lines.) It is for single channel normal (TR=0) operation only. Shutter speed <313 LVAL (CCIR). <263 LVAL (EIA). Video is composite 1Vpp from a 75 source.

Important note on using this signal for iris control.

The signal for iris video output is taken from the video signal after the gain control. If it is used for auto iris control, output video level can only be adjusted on the lens level adjust.

5.4.3. Trigger input

The trigger inputs on pin #10 12 pin Hirose connector is AC coupled. To allow a long pulse width, the input circuit is a flip flop, which is toggled by the negative or positive differentiated spikes caused by the falling or rising trigger edges.

The trigger polarity can be changed. Trigger input level 4 V ±2 V.

The trigger-input impedance is 10 k. The trigger inputs can be changed to Camera Link input.
