WINDIAG
Suspends normal operation and allows diagnostic
routines. Values are:
ON (Permits normal system operation, including the boot
project, and disables the WINDIAG diagnostics from
running; factory default)
OFF (Allow WINDIAG to run test; disable boot project and
normal system operation.)
Note: Setting both switch 8 and switch 3 to OFF (closed)
sets all communication ports to 9600 bps operation.
All serial communication ports must be set at 9600
bps before WINDIAG can perform communication
tests.
Note: Table 2-3 describes switch settings for RS-485 port operation.
You may want to review Section 2.3.6 on RS-485 configuration
before you set these switches.
