Bus cable lengths and pin assignment
The maximum length of cable which can be used depends on the selected baud rate. The following lengths should be understood as the total length of the main line plus any drop lines.
Baud rate | Bus length |
|---|---|
500 kbit/s | < 100 m |
250 kbit/s | < 250 m |
125 kbit/s | < 500 m |
The cable consists of two shielded wire pairs. One pair carries out the transmission. The second pair distributes the supply voltage.
