The data line must be connected from one device to the next (daisy chain). No other
type of wiring topology is allowed!
Auto addressing is not possible when using a repeater because the auto addressing
function is not forwarded by the repeater.
In addition, a network termination (150
Ω
) should be used at the end of every channel.
