The DMuX is a 24 channel demultiplexer which decodes DMX512 (1990 or earlier) signals and converts them
into 0 to +10V analogue signals. A negative output model is available on special order
POWER CONNECTION
The DMuX requires no external power transformer and should be connected directly to a mains voltage as
indicated on the unit's rear panel.
Applying mains to the DMuX in the absence of a DMX input signal will produce a fault condition, indicated by
'Flt' in the display.
DMX CONNECTION
Buffered DMX input and through connection to the DMuX may be made using either the 5-pin XLR on the
front panel or the 3-pin XLR on the rear panel, as you choose. In all cases XLR's should be wired according
to the USITT standard:- pin 1 screen, pin 2 data negative, pin 3 data positive. Pins 4 and 5 on the 5-pin XLR
are not used.
ANALOGUE CONNECTION
Analogue output channels are as shown below. Whether you use the four 8-pin DIN's on the front or the rear
panel, as shown in Fig. 1, or the six 5-pin DIN's on the rear, as shown in Fig. 2 is again a matter of choice.
The analogue output voltage is 0 to +10V. 0 to -10V units are available to special order. Connectors are
labelled to indicate which channels of the 24 they refer to.
SETTING THE DMX START ADDRESS
The DMuX requires one start address which refers to a group of 24 consecutive DMX channels.
Use the buttons '+' and '-' to select the desired start address, then press 'STORE'. The letters 'ADD' will
appear in the display to indicate that the address has been stored.
OUTPUT FROM THE DMuX
Output is indicated in the monitor LEDs.
