access the Serial Ports function. The Serial
Ports dialog appears.
2. Verify the MON2000 serial port Usage
setting.
(a) Determine the GC Controller serial port
to which you are directly connected.
(b) In the Serial Ports dialog, ensure that
the Usage setting for the port is either
“SIM-2251” or “User_Modbus”.
If the setting is incorrect, change it by
using the provided combo box.
3. Verify the Baud Rate setting.
WinMB accepts the following baud rates:
300, 1200, 2400, 4800, 9600, 14400, 19200,
38400, 57600, 115200.

inspect the serial line
connection at the GC
Controller Terminal Board.
