If you need more than one speaker (audio zoning) on your site, you have the following options:
l
Use VM22A audio units (with built-in MIO card only) to connect up to 20 loudspeakers. Install one or two
VM22A units connected in cascade:
o
Unit 0 is controlled by the MIO card, and drives loudspeakers 1 to 10.
o
Unit 1 connects to unit 0 via the loop connector on the VM22A, and drives loudspeakers 11 to 20.
l
Use VM22E audio units to connect up to 32 loudspeakers. Install up to 8 VM22E units in cascade:
o
Unit 0 drives speakers 1 to 4.
o
Unit 1 drives speakers 5 to 8…
l
Use the IP audio outputs on your IP cameras with (built-in) speakers. This feature is available with firmware
version XOa 3.02 and above; and for specific camera models only. For more information, see the
Supported IP
Camera List (26742).
l
Use an IP audio device such as the Axis Network Horn Speaker (C3003-E). Usage is similar to IP cameras
with audio out capabilities. For details, see
Using IP Audio Devices on page 52.
You use the XO client software to assign the different speakers to the cameras. For each camera, you can
choose:
l
One output on a VM22 output switcher
l
One or more outputs on IP cameras.
13.2.2 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).
