8.5 Setting of baud rate and node address (node ID)
Baud rate
For establishing communication, all devices must use the same baud rate for the
data transfer.
l The baud rate can be set via the coding switch at the module.
Node address
Each node of the network must be assigned to a node address, also called Node ID
within a range of 1 ... 63 for clear identification.
l A node address in a network may be used only once.
l The node address must be set with the coding switch at the module.

1. Switch off the voltage supply of the module.
2. Use the coding switch to set the required baud rate.
– Select "9x" (x = value for the required baud rate)
3. Switch on the voltage supply of the module.
– The LEDs ER, RD and BA are blinking with a frequency of 1 Hz.
4. LEDs ER and BA go off after 5 seconds, and the set baud rate is stored.
