Digital signals
All digital input and output signals will be confined to the same D-sub connector and have a common
ground. The four input signals will be scanned synchronously, and the outputs will be set synchronously.
Digital input signals
The digital in-signal can be used to monitor external equipment by registering, for example, error signals
or event marks. An event mark can be used as a trigger for watches. The measured digital signals can
be shown as a curve in UNICORN. The unit will handle both open/closed circuit and TTL-type voltage
signals. An open circuit is interpreted as logical 1 and a closed circuit as logical 0.
