Toshiba IK-TF2 instruction manual EXT Trig External trigger, Pulse SNR1 Pulse Sync Non Reset

7￿5 EXT TRIG (External trigger)

Charge begins to accumulate after the trigger input, and 1 field or 1 frame images are output. There are three modes: 1PULSE SNR, 1PULSE SR and 2PULSE.

The RGB terminal trigger input and index output interface are as shown below.

*Image output after 1 V (Trigger pulse doesn’t pass the VD falling.)

*Image output after 2 V (Trigger pulse pass the VD falling.)

*Image output after 2 V (Trigger pulse pass the VD falling.)

A image is output at the first field after the end of the exposure.
