STEP 4: E2E Baud Rate Settings
Because the COM A and COM D networks of an RMCC/BEC/BCU must communicate at the same baud rate,
all I/O boards connected to the RMCC/BEC/BCU were also set to communicate at 19200 baud. Because the
default E2E baud rate for I/O networks is 9600 baud, you will need to change the COM2 baud rate setting.
This must be done in the C3: Serial tab of the E2E’s General Controller Info screens.
1. Log into the E2 with Level 4 password access.
