a) Input of External HD/VD signal (Factory Pre-set)
Video output of CV-M90(rev.c) in factory pre-set mode can be
synchronized with external HD/VD signal (4.0Vp-p ± 2.0V at 75

terminated) .
For TTL level input (2.0 ~ 5.0V), set SW301 switch located on
PK8088 board to OFF position.
For more information, see ”5. Pin Assignment” and ”7. Mode Set-
ting”.
b) Output of Internal HD/VD signal
To output internal HD/VD signal (4.0Vp-p at 75

Non-terminated),
make the jumpers JP306/309 to short-circuited and JP305/308 to
open-circuited.
Each jumpers are located on PK8088 board inside the camera.
For more information, see ”5. Pin Assignment” and ”7. Mode
Setting”.
Note: Internal HD/VD signal output is 75 W impedance.
External trigger mode of CV-M90(rev.C) allows 3 different driving
modes, as follows.
a) Random Trigger Mode –
1 (Asynchronous reset/Exposure control by ext. trigger
and 7- step fixed shutter)
b) Random Trigger Mode –
2 (Exposure control by ext. trlgger and Ext. VD signal)
c) Long Time Exposure Mode
(Exposure control by ext. VD signal)
Followings are the details of each triggering modes.
