Now, set the channel number over which the SUP protocol runs. In addition, set the slave address of the 20-
mA unit. This address must be set with the same value in the 20-mA unit (refer to the following figure).
For the first use of the 20-mA unit, the following device configuration must be set on the 20-mA unit:
•
Bus protocol: mod
•
Device address: 1
•
Baud rate: 9600
•
Parity: no
