OptiStar CG08(-C) CAN bus • 45
Determining user address (Node-ID) and Baud
rate
Each OptiStar Gun control unit, which operates in the CAN network, must
have assigned an individual user address (Node-ID). The Baud rate
setting enables the transmission speed setting. The Baud rate value can
be set by editing the system parameter P05, and the Node ID value can
be set by editing the system parameter P06.
Baud rate - system parameter P05
P05 value Baud rate
0 20 kBit/s
1 50 kBit/s
2 100 kBit/s
3 125 kBit/s
4 250 kBit/s
5 500 kBit/s
6 800 kBit/s
7 1 Mbit/s
Default value of system parameter P05 = 3
The Baud rate is selected with 125 kBits as default. This setting permits a
maximum cable length of approx. 500 m from the first to the last CAN bus
client. If longer cables are used, select a lower Baud rate.
Node ID - system parameter P06
CAN Node-ID 1-127
P06 value CAN Node-ID
1-127 1-127
