APPENDIX- Contact Closure Wiring Details
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!
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 push-button 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.
