Charge begins to accumulate after the trigger input operation (in the RS232C mode, by RS232C command
input, in other modes, by trigger pulse (TRIGGER) input to the DC IN/SYNC terminal) or trigger signal input
to the DIGITAL terminal and 1 field or 1 frame images are output. There are four modes: 1PULSE SNR,
1PULSE SR, 2PULSE and RS232C.
The DC IN/SYNC terminal trigger input and index output interface are as shown below.

Charge begins to accumulate after the trigger input operation to the DC IN/SYNC terminal or trigger signal
input (LVDS) to the DIGITAL terminal and 1 field images are output.
The exposure time is set to 0.06 to 20 ms on the menu.
