Figure 2 Direct AI-Net Connection

This connection mechanism can be used with any radio module, it has the advantage that the Intravee

audio is sent directly to the PXA-H100 for maximum quality. However Nav commands issued when the

Intravee is the selected source cannot be heard.

This type of connection must be used when a radio module other than the BM53 or BM54 is used, for

example C43 or BM24.

When using the direct AI-Net connection the Intravee must switch the audio input of the PXA-H100

between the HU and AI-Net ports, to do this use the PXA Direct menu option, see below, or the console

command

pss on

to disable processor source switching, issue the command

pss off

When issuing the pss off command, make sure that the Intravee source is NOT selected, otherwise the

input will be set to the AI-Net port and no radio audio will be heard.

3. BMW DSP Menu Interface

When the Intravee detects the existence of a PXA-H100 device it will automatically emulate the BMW DSP

amplifier. When the Nav computer detects the BMW DSP amplifier it will add the DSP option to the main

menu.
