The diagnostics procedure requires Windows Hyperterminal (or
other terminal emulation software, such as PROCOMM). Use the
settings appropriate to your application.
1. Connect one end of the PC data cable to
the DB9 maintenance port connector on the rear of
the ADCU. Connect the other end to the serial port
on your PC (a 9-pin/25-pin connector adapter may
be needed for some PCs).

allow the system to complete full initialization.
Data should be scrolling on the PC display to
identify any system problems detected. If no data
is seen, recheck your connections and the terminal
software setup.
