UMG 511
Bus structure
• All devices are connected in a bus structure
(line).
• In one segment, up to 32 participants can be
switched together.
• The cable is terminated with resistors at the
beginning and end of a segment.
• Repeaters (power boosters) must be used with
more than 32 participants in order to connect
the individual segments.
• Devices with terminated resistor have to be
supplied.
• We recommend to install the master UMG at
the end of the segment.
• In case that the master UMG with terminated
bus resistor will be removed, the bus is not
under operation.
• In case that slave UMG with terminated bus
resistor will be removed or is not switched on,
the bus is can be unstable.
• UMGs which have no termination can be re-
placed without any interruption of the bus.
