DMX512 to AMX192 Converter

model: DMX1AMX, DMX2AMX

technical data sheet

The DMX to AMX converter is available in two standard
config urations. The single out put model handles up to
192 dimmers while the dual output converter extends the
unit’s capability to 384 dimmers. Custom converters with
any number of DMX inputs and AMX output s are also
available. These custom units are seamless; they handle
the problems of two DMX inputs covering one AMX
output and CD-80 6K/12K modules without g aps in the
DMX numbering.

The DMX to AMX converter allows the installation of control consoles that lack AMX outputs into a system
of AMX dimmers. Typical uses include upgrading the console of an AMX lighting system or adding AMX
outputs to a DMX only console (you may purchase just the circuit board). If you would like assistance in
your application, please give us a call. We like to talk with our customers.

The DMX512 to AMX192 converter is based on a 20 MHz high perform ance m icrop roc es s or (Zilog Super8). T he

program is written in asse mb ly lang uage for m aximum speed. The conver ter accepts any DMX signal: DMX512,
DMX512/1990, 4 or 8 uS mark- after-br eak. T he converter outputs AMX 192 at 100 update s per second. O n dual
output models (384 dimmers), the two ports run in parallel. That is dimmer 1 and dimmer 193 are output at the same
time using two separate digital to analog converters. This doubles the speed over designs using one digital to analog
converter. The two outputs have separate drivers so a short on one output will not affect the other.

The circuit board is available without the enclosure for mounting inside a console. The tested board comes with wiring
information but installation should be done by a technician trained in lighting cons ole repairs . T he power s upply is
included on the board and may be jumpered for 100-120 or 208-240 volt operation.
