Control Connector

Be sure to configure the

Digital Audio Machine

or contact closures or

voltage inputs before

connecting any wires.

This connector provides all of the signals needed to interface to the Digital Audio

Machine. In addition to serial control, the first fifteen files of the Digital Audio

Machine may be played, paused or stopped using eight parallel inputs located on the

rear connector. These inputs may be either contact closures such as momentary

buttons, or voltage inputs from a controller such as a PLC. A switch located on the

side of the unit next to the connector selects between the two input types. More

information on these inputs may be found in the section entitled Parallel Control.

The pinout of the Control Connector is shown below:
