2.2 Setting the Baud rate
DIP switches 6 to 8 can be used to set a fixed baud rate for the gateway
Section “1.5.2 Baud rate”, page 22. If you want to use the automatic
baud rate detection function (as described in CiA 801) instead, follow the
steps below:
▶
Set DIP switches 6 to 8 to OFF.
When the gateway is attempting to detect the baud rate, the ST LED will
flash red and green and the gateway will adopt the field bus master's baud
rate.
Cyclical CAN frames need to be sent on the field bus in order for the baud
rate to be detected successfully. Otherwise, the gateway will not be able to
detect the CAN baud rate.

If the device is unable to automatically determine the baud rate,
use the DIP switches to set a fixed baud rate or add another
CAN module to the system.
