 Incorrect EBSAP Group number – if you use expanded BSAP the
EBSAP group number must be correct; if you are not using EBSAP,
the group number must be 0.
If IP communications do not function, it is often due to incorrect IP
addresses or masks. Check to see that the IP address you defined for the
ControlWave EFM is compatible with the range of IP addresses defined
for the communication line on which the unit resides. Also check that
the IP address of the default gateway is correct.
WINDIAG is a software-based diagnostic tool you use to test the
performance of I/O modules, CPU memory, communication ports, and
other system components. .
WINDIAG is a PC-based program, so the EFM must be attached to and
communicating with a PC running WINDIAG. Set configuration switch
SW2-8 OFF (closed) on the CPU module to enable the diagnostic
routines.
Establish communication between the EFM (with/without an
application loaded) and the PC with a local or network port under the
following conditions:
 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 EFM in diagnostic mode.
 Use a null modem cable to connect RS-232 ports between the EFM
and the PC; use an RS-485 cable (see Section 2.4.4) to connect the
RS-485 ports of the EFM 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 EFM 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 EFM 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.

RS-232: 115.2 kbd using IP PPP protocol
To run diagnostics, set RS-232 to 9600 baud by setting CPU
switches SW2-3 and SW2-8 OFF.
RS-232: 9600 baud, 8 bits, no parity, 1 stop bit, BSAP or
