technical data sheet

The DMX DECELERATOR II is a DMX512 isolator and re-timing device. It can
receive any signal within the DMX512 specification and it can accept some
signals outside of the specification. It produces a DMX output signal with
“relaxed” timing characteristics which are required by some DMX receiving
devices. In addition, a BYPASS mode is provided. When this mode is selected,
the DMX DECELERATOR II copies the timing from the input signal to the

isolated output directly with no changes. This can be useful for diagnosing problems with isolation versus timing.
The DMX DECELERATOR II is powered by a universal input supply. Its DMX512 input is fully opto-isolated and

protected against transient voltages.
