RS232 to DMX

model: 2322DMX

technical data sheet

The RS-232 to DMX interface allows advanced A/V control systems
and computers to operate standard DMX512 devices such as
dimmers and moving lights. It can also be used to allow an RS-232
based control system to receive DMX512 data. The RS-232
protocol used for this com munication is m ade up of sim ple ASCII

strings sent or received at 9600 baud. The interface can set and
fade DMX channels to specific levels. It can also record and play 20 presets, each with individual fade times. The
interface can be used to capture incoming levels produced by an outside D MX source. Other comm ands available
include support for remote preset selection panels (using our Preset 10), monitoring of DMX channel levels, selection
of DMX input or output m odes, and downloading of new softw are. All options and presets are held in the non-volatile
memory.

The DMX port is fully opto-isolated to avoid ground loop problems and to help protect equipment. The RS-232 port
appears on the front panel as a standard DB-9 connector. Another RS-232 port is available on the rear panel through
a 3 pin female XLR connector. Only one of these connections can be used at a time. For simple operation, the
W indows Hyperterminal program can be used to com m unicate with the interface. The RS232 to DMX interface is
backed by our standard 5 year warranty.
