Symetrix Announces Control I/O

Symetrix, a leading manufacturer of audio signal processing products, announces the release of Control I/O, an RS-485 control peripheral for the SymNet Audio Matrix system.

This inexpensive add-on expands SymNet’s external control capabilities by providing additional ports to a SymNet audio network:

¥ Eight control voltage inputs for encoders, pots or up to 16 contact closures.
¥ Four binary relay and eight open collector outputs.
¥ Four powered Adaptive Remote Control (ARC) ports.
¥ 15-pin joystick MIDI port allows SymNet to connect with standard MIDI
control surfaces and other software/hardware products.

Communication between the Control I/O and a SymNet ring is accomplished via RS-485, so the unit can be placed thousands of feet away from the SymNet system. This significantly increases the flexibility of control routings when designing and installing a SymNet system. Additionally, Control I/O can function as a stand-alone controller for non-SymNet products by using ASCII text messages to configure the unit.

SymNet software support for the Control I/O is included in the SymNet Designer v3.52 application. If you are using any prior v3.5 releases, we strongly recommend downloading the latest software release v3.52.
