The Merge takes two DMX data stream inputs and combines them into a single DMX output data stream.
Additionally, a 24-channel analogue data stream may be input, multiplexed and merged with the master
DMX output.
Where there are multiple inputs to a single output channel, it is the highest level signal received that is
output (HTP).
Inputs may be offset, one from another, to begin at any point in the output stream. Inputs may also be
truncated, so that only a selected number of channels is added to the output.
The input DMX signal lines are opto-isolated to provide a high degree of isolation between data paths.
OPERATING VOLTAGE
The Merge is designed to operate on 230V AC. A 115V version is available to order.
MOUNTING
The Merge mounts in a standard 19 inch rack. It is one rack unit high.
HARDWARE CONNECTIONS
All connections are made via the rear panel.
MAINS INPUT
Fit an appropriate mains plug and connect to the mains. In the UK the plug should be fitted with a 3Amp
fuse.
CONTROL INPUTS
DMX input is via two XLR5 male connectors, wired according to the USITT(1990) protocol.
Analogue input is 0 to +10V via a 25-pin sub-D (male) connector. Channel connection details are shown in
Fig. 9 below.
DMX OUTPUT
The DMX output is via an XLR5 female connector, wired according to the USITT(1990) protocol.
OPERATION
When power is applied to the Merge, the letters 'run' will appear in the display.
If no offsets are programmed, the second DMX input stream is superimposed directly on the first and
output will occur according to the highest takes precedence rule, i.e. the highest of the two DMX input
levels and the analogue input will be output.
