Determining user address (Node-ID) and Baud
rate
Each 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.

6

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.
