2-2-4. DI/DO
The DI/DO panel provides a glimpse of all DI and DO signal
statuses from the connected cameras. You can manually trigger a
digital output by clicking on its indicators.
When a digital input is triggered, its status will also be indicated on
the panel.
Please note that DO is triggered by one click. You should then
click again to disable the DO. Otherwise, the DO signal will be
continuously triggered. As the result, if the DO is configured as an
alarm trigger, many alarm messages will be generated.
