MLX-20L Failure
If the MLX-20L console does not work, follow the steps below.
Replace the MLX-20L console with one that is known to be working
(if available).
If the failure persists, or if a working MLX-20L console is not
available, connect the original MLX-20L console directly into the
appropriate MLX jack on the control unit using a cord that is known
to be working.
If the trouble clears, replace the original D8W-87 cord.
If not, use the PC as your maintenance terminal and then troubleshoot
the leftmost MLX module. See "Module Problems" on page 4–34 for
instructions.
