audio units to connect up to 32 loudspeakers. Install up to 8 VM22E units in cascade:

Setup for VM22A
Note
The VM22A audio switcher is only compatible with built-in MIO cards, not with the MIO cards in the
external XO I/O Interface USB modules.
You need a specific cable to connect the VM22A to the XO device.
Connect the cable to the back of the device as illustrated below. Respect the colour code (yellow = STROBE;
white = AUDIO OUT, shield = AUDIO GND, red = CLOCK, and green = DATA).
