M-Bus Master MultiPort 250D
3.8 M-Bus Repeater Input
Setting as master or repeater.
Kamstrup M-Bus Master MultiPort 250D can be used as
both master and repeater.
Used as master, up to 250 meters can be connected in
an M-Bus system.
The repeater function makes it possible to extend the
size of the M-Bus network both as to number of meters
and total cable length. If one master and four repeaters
are installed in a network, the total cable length can be
extended to approx. 14 km, and up to 1250 meters can be
connected.
The master is configured as repeater by placing the
jumper on the connector marked Repeater. Using an
M-Bus Master MultiPort 250D as a repeater, the M-Bus
network in front of the repeater is connected to "M-Bus
Repeater In" on terminals 53 and 54. The following meters
are connected to M-Bus Out on terminals 24 and 25.
