 Turn CPU module switch SW2-8 OFF to run the WINDIAG

program. Setting this switch off prevents the boot project from

running and places the Micro in diagnostic mode.

 Use a null modem cable to connect RS-232 ports between the Micro

and the PC; use an RS-485 cable (see Section 2.4.4) to connect the

RS-485 ports of the Micro and the PC.

 Reserve the port running a diagnostic test for exclusive use; you

cannot use that port for any other purpose during testing.

 Connect any Micro communication port to the PC provided their

port speeds match. Most PCs have a COM1 port (typically RS-232

and defaulted to 9600 bps operation).

 Configure the Micro communication port to be tested using

WINDIAG for 9600 baud, 8-bits, no parity, 1 stop bit, and

BSAP/ControlWave Designer protocol operation. Communication

port COM1 is only forced to 9600 bps operation when you have set

switch SW2-3 on the CPU module to OFF.

To run diagnostics, set RS-232 to 9600 baud by setting CPU

switches SW2-3 and SW2-8 OFF.

COM2 CPU RS-232: 9600 baud, 8 bits, no parity, 1 stop bit, BSAP or
