The DMX512 to Analog Converter is an interface device which allows a DMX512 control

console to control 0 - 10 volt analog dimmers or other 0 - 10 volt devices.

The input to the converter is electrically isolated from the outputs. This prevents ground

loops in the dimming control system as well as protecting the console from damage in

the event of dimmer failure. In addition the input is protected against mis-wiring and will

accept up to 120 volts on its DMX512 input without damage to the converter. The

outputs are protected against positive voltages coming up the control cable. Damage to

the converter may occur if high negative voltages are placed on its outputs.

The input accepts DMX512 as specified by the Untied States Institute of Theater

Technology (USITT). The outputs meet the proposed ADC-10 specification.
