MX Control Card Configuration
A-14 Vicon MX Hardware System Reference
Audio Option
To connect an audio ADC card in the MX Control to third-party devices
for capturing audio data, you must plug the device into the
Audio
socket on the rear of the MX Control using a standard RCA plug.
Important
There can be only one audio ADC card installed in an MX Control within a
Vicon MX architecture that contains Vicon Workstation application software.
Depending upon the options you ordered for your Vicon MX system, your
MX Control may not have an audio ADC card installed. For details of how to
integrate one later, see Installing an MX Option Card on page A-16.
The audio ADC card is a 4-channel device for capturing audio data.
The impedance is 600
Ω. This card supports fixed analog sample
rates, which are dependent on the MX camera frame rate specified in
the Vicon application software. The higher the sampling frequency,
the fewer analog channels there are available. Each channel has a
programmable gain, which can be set to +/- 10 volts, +/- 5 volts, +/
- 2.5 volts, or +/- 1.25 volts. For details on specifying these settings,
see your Vicon software documentation.
Caution
For audio input from a microphone, the audio signal must be amplified before
being sent to the audio ADC card.
