Swapping Channels via Remote Control
The GPI swap controls are available only when the MXA is used in an
FR-7000 frame. To control channel swapping from the GPI, set the
Remote/Local
jumper to
Remote
. The default position for the Remote/
Local jumper is
Local
. When the jumper is set to
Local
, the GPI controls
will not function. When the jumper is set to
Remote
, the Hex switch
swap controls will not function. The GPIs are active low.
To swap AES1 Left/Right with AES2 Left/Right, or Channel A Left/
Right with Channel B Left/Right, the Channel GPI control should be
enabled.
The Left/Right GPI control should be enabled in order to swap AES1
Left with AES1 Right; AES2 Left with AES2 Right; Channel A Left with
Channel A Right; or Channel B Left with Channel B Right. When the
Left/Right GPI control is asserted, both left/right pairs are swapped.
Audio Embedding
All MXA modules embed audio data into one audio group at a time,
filling positions W, X, Y and Z.
See
Figure
9-13
“Audio Group” on
page 157 for more information. The group embedded is selected using
the
Hex
switch on the module edge.
The MXA-6801-A2 accepts only two audio channels: Channel A Left
and Channel A Right. Positions W and X are used for Channel A Left
and Right, respectively. When using the MXA-6801-A2, audio group
positions Y and Z are muted. Since the MXA modules embed audio in
four channels at a time, it is
not
possible to use a second MXA-6801-A2
to fill positions Y and Z with additional audio data.
The MXA-6801-A4 accepts four audio channels: Channel A Left,
Channel A Right, Channel B Left, and Channel B Right. These channels
are embedded in positions W, X, Y, and Z, respectively.
