The input to the DMX Opto Isolator is passive, and, since the
DMX512 standard specifies an active input, the DMX Opto
Isolator's input does not meet the DMX512 specification. This is
not a serious drawback, however, since the Opto Isolator is
designed to be the only load on a particular console port
(whereas there are usually several dimmers connected to one
port). The isolator's output meets the full DMX512
specification, however, and restores the full drive capability of
the port. (The fact that the isolator's input is passive is
another reason it is recommended that it be placed close to the
console).
