About the diagnostic
setting
This setting is only used for troubleshooting at the Northstar
factory. Do not use this setting.
NOTE:

it’s configured to either
COPY PORT1
or
COPY
PORT2
, and one of the copied ports is in 0183
output mode—unless the diagnostic port’s baud
rate is fast enough to handle the number of
characters. Because the diagnostic port’s baud rate
can now be changed, the 957 will always display
this precautionary message before you actually
reset the baud rate:
