Parallel Control
The Binloop’s Parallel Control interface is designed to provide a very
basic control from simple voltage and contact closure inputs. This
interface also has 3 dry-contact relay outputs and 2 TTL level outputs
that indicate the status of the Binloop. All of these signals are available
on the DB-37
Parallel Control connector located on the back of the
Binloop.
