trigger signal inputs. The trigger signal is used
to resume a sequence after a pause. This action
is useful to synchronize the execution of a
sequence with another device.

Pin 11 of the J1 connector is internally pulled
down to A COM with an approx. 50kΩ resistor.
To use the trigger input, an active low TTL
pulse of 10μs or more is required.
