INT Mode
Sends the constant cyclical (2V) trigger pulse for E-DONPISHA to the XC-7500/8500CE camera module. The unit outputs
the updated video in every 1/30 sec. (EIA format) or 1/25 sec. (CCIR format). Set the TRIG switch on the front panel to INT.
In this mode, the video signal of the unit sets the field secured. Setting the internal switch S5-6 to ON switches the field.
