Caution: MLSUC500 / 1250 is not compatible with PoE
(Power over Ethernet) networks. Connecting to a PoE
network may cause the unit to stop functioning. In that
event, disconnect it from the network segment and power-
cycle the MLSUC500 / 1250.
The MLSUC500 / 1250 assumes the role of Bus Master on
the MLS Spine. This means that all the RB2000s should
be given consecutive, unique non-zero addresses, refer to
RB2000 documents.
The last unit at each end of the MLS spine should be
configured to terminate the two RS485 signal pairs, A-B
and Y-Z. In the case of an RB2000 being the last device this
is simply a matter of sliding the switch behind the address
setting switches to the ON position.
The entry for wiring into the main enclosure can be made by
drilling a conduit of around 20mm at the bottom or either side
of the enclosure.
Note: The spine connections from the MLSJ8 are prewired to
the terminal blocks.
