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 communication is made up of
simple 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 DMX source.
Other commands available include support for remote preset selection panels (using our Preset 10), monitoring of
DMX channel levels, selection of DMX input or output modes, and downloading of new software. 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 Windows Hyperterminal program can be used to communicate with the interface. The RS232 to
DMX interface is backed by our standard 5 year warranty.
