APPENDIX
Once the port has been wired, we can assign it to the VX Indications as below:
Once this is complete and the studio is logged back into a show, lines ringing on the VSet will activate this output. In both of
these, notice how the output and input commons are wired.
REMEMBER:
LW GPIO channels do not advertise to the network, so you will not see GPIO channels in the Browse window of
destinations fields.
WHY RELAYS?
We are specifying the use of relays / opto-isolators because the GPIO port cannot source or sink enough
current to drive an indicator by itself. The xNode manual has more on the current limitations of the GPIO port. If you need to
deviate from these configurations, please consult that text.
You’ll find wiring examples in the GPIO xNode and Mixed Signal xNode chapters of the xNode manual available here:

The instructions found above will apply to Legacy GPIO Node, Element, PowerStation, and QOR GPIO.
Single Mix Minus Routing with xNode
While all Axia consoles and some other modern manufacturers’ consoles create their own mix minuses for each caller channel,
there are some cases where only a single mix minus can be generated and more than one caller fader is desired. The challenge
now is creating a separate mix minus for each fader so the caller on fader 1 can hear the caller on fader 2 and vice versa.
The xNode has a mixer matrix that can be used to overcome this obstacle. One thing to keep in mind is the internal mixing
instance will use additional sources in the xNode. You’ll see what we mean as we move forward here. The idea is to use a pair of
unused sources in the xNode to provide each separate Mix minus.
We will start with an xNode with its factory defaults loaded.
As before, we will go to the
SIMPLE SETUP
page and choose
8x8 Mono Mode.
