Total length of wiring
The capacity of the total length of wiring influences the signal quality. Dependent on the baud rate, the following network expansion is pos-
sible: (Cable type: JYSTY nx2x0.8)
Transmission speed
Max. network extension
Max. distance to the slave
The voltage drop on the bus lines depends on the quiescent current (the number of slaves) and the resistance of the wire. This voltage drop
limits the distance between the AMBUS
Max. distance @ 5 slaves
Max. distance @ 10 slaves
Max. distance @ 20 slaves
M-Bus terminals
M+ M-
There are three terminal pairs, so that the designations M+, M- serve to differentiate between the M-Bus lines. The polariza-
tion is irrelevant for M-Bus installations.
