Timing chart for low-speed NON-RESET mode (1N) video
signal output
Using the E-DONPISHA Function
The NON-RESET mode (1N) video out (continued)
Low-Speed
To set to low speed, set the S7-6 switch on the SG-235
board to ON. The exposure duration is controlled by the
input trigger.
External Control
Set the S5 switch on the SG-235 board to the minus (–) position.
Set the S7-5 and S7-6 switches on the SG-235 board to ON.
Set the T3 (100 µs :1/100000s to 1 µs : 1/1000s) on the S6 switch
on the SG-235 board.
You can control TX (exposure time) by setting the external trigger
pulse width T2.
