6 Limitations

Removing the audio group when de-embedding will only remove the audio group to
which the card is configured to read. This may leave 'holes' in the embedded audio.
Embedding audio into the video signal after removing the audio will start
embedding as soon as any of these holes are encountered. This may result in the
corruption of other audio groups which were present after the 'holes'. This does not
apply if Network embedding products were used to embed audio as they all use the
same packet distribution.

7 Connector modules

The audio connector on the backplane is a 25 pin female d-sub connector with UNC
threads. The video input and output connectors are BNCs. The RJ45 connector is
used for alarms.

Figure 3 AAV-DMUX-C1 Connector module.

The Alarm outputs are active low open collector outputs.

The signal connections are shown in the figures on the next page.

CAUTION:

The AAV-DMUX card may not be used with an AV-MUX-C1 connector

card. Though no damage will result and an audio signal will be de-embedded, the
audio signals will be distorted or silent.
