MX Control Card Configuration

A-24 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-25.

The audio ADC card is a 4-channel device for capturing audio data.

The input 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.

Installing MX Option Cards

The following sections describe how to install available MX option

cards in the Device 1 or Device 2 slot in the rear of the MX Control:

• analog ADC add-on card

• audio ADC add-on card

Caution

Before opening the MX Control, see General Cautions and Access

Instructions. When installing cards in the MX Control, be careful not to touch

any tracks on the cards.
