3. The last type, Raw COMPEL Data, must also be enabled by a non-volatile con-
trol. (Actually, it is a factory setting that can only be modified with debug access.)
When this type of COMPEL data stream is being processed normally by the IRD
host processor, it is also output as-is (in binary witn non-printing characters) to the
Printer. While Raw COMPEL Data is being dumped, it has exclusive access to
the Printer device, and no other outputs can access the printer until the dump has
completed.

Audio/Video
Check
This test puts out a video test pattern and audio test tones to allow verification of video
and audio connections. The video pattern is vertical color bars. On Port 1, the audio is a
slowly pulsing (triangle-wave) tone with a higher frequency on Right than on Left. On Port
2, the audio is a slowly pulsing (sine-wave) tone also with higher frequency on Right than
on Left. On each port, the audio tones alternately pulse (~1 second) left then right, then
repeat. Use the following steps to enable or disable this audio/video test mode:
a. From the RF Input Check screen, press the right-arrow button to bring up the
Audio/Video Check screen.
b. The Audio/Video Check screen will indicate that the test mode is either
"Enabled" or "Disabled".
c. Press ENT to switch the test mode between "Enabled" and "Disabled".
d. Press the left-arrow button to return to the RF Input Check screen or ESC to
return to the Installation Testing screen.
