Trigger Function
External trigger
The external trigger can either be a CMOS logic-level signal supplied to the trigger input
or it can be activated by shortening the trigger input terminals.
A. Using a CMOS logic-level signal
1. Set the power switch on the side of the unit to OFF and connect the trigger cable.
2. When the connection has been established, set the power switch to ON and use the
SETUP menu screen to select the setting "EXTRN" for the trigger function.
The trigger is activated at the falling edge of the logic-level signal.
Set the "High" level of the logic-level signal source to 5 V±5%.
