Startup
5.2.5 GPI/DC (Hardware description)
Up to four GPI pins
[5] (General Purpose Input) together with a
onboard DC supply (12 V DC, 50 mA) are available as additional
digital control lines.
Each GPI provides either level (Hi/Lo active - non-latching) or edge
(rising/falling - latching) triggering.
A VCA functionality is incorporated to allow the connection of an
external, linear potentiometer (10 kOhms).
