MLSUCA MK2 Product Descri pt ion
The MLSUCA MK2 is an embedded controller/web-page server for remote monitoring and control
of Ex-Or Digital Managed Lighting Systems, (MLS Systems). It also has the capability of
presenting its status information and receiving commands in BACnet protocol form.
As a controller/web-page server exclusively for the Ex-Or MLS System it is able to control and
display up to 700 lighting zones spread over a number of Ex-Or RB2000/MLS Bus served areas of
a building or campus. With the inclusion of the BACnet capability it is able to serve 450 lighting
zones.
For the lighting control and lighting status display application the MLSUCA MK2 takes the role of
Bus Master on the RS485 Spine linking a number of RB2000s each of which drives an MLS Bus
capable of supporting up to 100 separate lighting zones comprised of up to 200 individual
presence detectors with photocells.
Control functions in the lighting application can be either pre-programmed actions governed by an
onboard time-of-day clock or manual interventions delivered via the supported web-page from any
co-networked Personal Computer running a web-browser. With the BACnet capability installed
real-time control actions can also be initiated by remote BMS devices.
Conversely via the BACnet protocols information gathered by the lighting system’s detectors,
typically occupancy data, can be passed to other BMS disciplines.
