Matrix Mk.II Rack Installation Manual
Section 5
Installing Data Cables
All Matrix II dimmer racks accept data in Ethernet and discrete DMX formats. All control connections
are made at the rear of the processor module, on the data PCB that can be identified by the attached
ribbon cable. There is one data PCB per rack. Use provided lance and forms as a tie off for DMX and
Ethernet cables in the swing frame racks.
Ethernet
Two standard RJ45 Ethernet sockets are provided on the data PCB, one for
the reporting connection (Dimstat) and one for the control data connection
(Merger). These sockets accept standard 10- or 100-base-T network
connections and receive dimmer intensity levels and transmit dimmer status
information using the DimStat protocol.
Discrete DMX
Separate data terminals are included for DMX for those installations which are
not using an Ethernet data network. Two sets of terminals are included (see
diagram opposite). The terminals are PCB plug and socket type and may be
removed for wiring. DMX-1 includes the RS422 connections to DimSTAT and
DMX-2 is for DMX only.
DMX wiring should follow the standards and topology as defined by the USITT
standard. Wiring a Matrix II connector is as shown to the right. Unplug the
terminal section for wiring.
