Self Test Procedure for CM401, CM402 and CM408
(For CM40x Firmware Rev 1.0S)
The following pages describe the operation of standalone self test software for System-5
control modules.
The self-test code is designed to be invoked in a module right after power-up and before the
SBC downloads code into the control module 386 board.
The self-test works in a fully assembled module as well as with just the upper board or just
the lower board connected to the CPU board. However, the upper board must be present to run
fader test modes.
All the three types of control modules have the same lower board. Because of this, the lower
board can be tested separately without an upper board connected. The self-test can be invoked
from the lower board knobs as well as upper board self test keys.
