Contact Closure Feature

The contact closure feature is used to trigger gain changes in the DSP. Any configuration that uses one or more switched gain objects (see Signal Manager software Help file ) can take advantage of this feature. The contact closure will trigger all switched gain objects at once.

All switched gain objects in a DSP configu- ration will be triggered by the one contact closure. It is not possible to trigger switched gain objects individually!

Wiring Diagram for Contact Closure

This feature requires the construction of a simple RS-232 cable (or through-adapter plug) that brings out pins 5 (GND) and 9 (contact closure trigger). These pins may be connected to a simple toggle or pushbutton switch that will be used to trigger a switched gain object in a DSP configuration. Refer to Signal Manager software Help file for available contact closure features.
