Chapter 8: Audio Module, Rev 1.1
Example 2
The Audio Module has the following connections:
Channel 1 = VHF
Channel 2 = Mic1, Mic2 (Fwd Bridge mics)
Channel 3 = Empty
Channel 4 = Mic 3, Mic4 (Wing mics)
Channel 5 = Empty
Channel 6 = Mic 5, Mic 6 (Aft Bridge mics)
Channel 7 = Mic 7 (Radio room)
Channel 8 = Empty
For example, an INI file contains the following ChannelEnabled fields:
ChannelEnabled1=1
ChannelEnabled2=1
ChannelEnabled3=0
ChannelEnabled4=1
ChannelEnabled5=0
ChannelEnabled6=1
ChannelEnabled7=1
ChannelEnabled8=0
During a buzzer1 audio test, the Log Window will read similar to the following:
Mike 1 test – chirp detected on channel 2 – 869.459 (359.906)
Mike 1 test – chirp detected on channel 3 – 1269.459 (659.906) (Note: is actually CH4)
Mike 1 test – chirp detected on channel 4 – 869.459 (359.906) (Note: is actually CH6)
Mike 1 test – chirp detected on channel 5 – 869.459 (359.906) (Note: is actually CH7)
And during a buzzer2 audio test, the Log Window will read similar to the following:
Mike 2 test – chirp detected on channel 2 – 869.459 (359.906)
Mike 2 test – chirp detected on channel 3 – 1269.459 (659.906) (Note: is actually CH4)
Mike 2 test – chirp detected on channel 4 – 869.459 (359.906) (Note: is actually CH5)
NOTE: If a ChannelEnabled field is not enabled (=0), the Log Window sequentially
numbers the next enabled channel. This is illustrated in Example 2. In that example,
ChannelEnabled1 is a VHF connection and therefore does not register a chirp in the
Log Window; ChannelEnabled2 has its RMS values listed as channel 2; however,
because the ChannelEnabled3 field equals 0, the Log Window lists the RMS values
for ChannelEnabled4 as channel 3.
