Trigger (option)
The rear panel of DP800 provides a digital I/O interface which supports trigger input
and trigger output.
Trigger Input:
The data lines of the digital I/O interface receive external trigger signal. The
source under control (namely the output channel) turns on the output, turns off
the output or inverts the output state when the preset trigger condition is met.
Trigger Output:
The data lines of the digital I/O interface output level or square signal when the
output of the control source (namely the output channel) meets the preset
trigger condition.
The 4 data lines of the digital I/O interface are mutually independent and can be
used as trigger input or trigger output separately.
The trigger connections are as shown in the figure below.
Operation Procedures:
1. Connect the cables to the connecting terminals according to the figure above
(pay attention to the corresponding relations).
2. Insert the connecting terminals into the digital I/O interface on the rear panel
(pay attention to the corresponding relations).
Press Trigger to open the trigger setting interface as shown in the figure
below. Press Trig to select trigger input or trigger output and the corresponding
setting interface is opened. The default is trigger input.
