REMOTE TRIGGER PORT
The system menu contains the remote trigger port option from where it can be enabled or disabled.
If enabled the remote trigger port on the processor allows you to select any of the first 8 user presets by pulling
one of 8 pins on the trigger port socket low. The rear panel trigger port socket is a 9 pin male D-type whose con-
nections are shown below.
The trigger port socket contains an earth return connection pin for the 8 opto-isolated trigger pins. When the
trigger pins are connected to the earth return pin they will change the currently active preset to the user preset
triggered by that pin. If more than one pin is pulled low at the same time the pin with the lowest number will take
priority. E.G. if all pins are pulled low trigger 1 will take priority. Once the trigger pin disconnects from the earth
return connection the processor will return processing to the normally active preset.
Relays, contact closures, open collector and other hard wiring arrangements can be used to perform the appro-
priate connection between the trigger port pin and the earth return pin.
If you wish to trigger a factory preset you will need to copy that factory preset to a user preset first.
