5.0 Digital input and output
This chapter discusses the ACE-RIU's digital input and output.
5.1 Digital input
The ACE-RIU provides contact-sensing digital inputs. No power is required. Connecting the
digital input and digital input ground lines together triggers the digital input.

The digital inputs on the ACE-RIU are useful for providing a direct interface with press-to-
talk (PTT) switches. The PTT input is fed directly into the model, thereby eliminating control
latency associated with host I/O systems.
