[SML] DMX through TRS plugs?

[e-mail frank.wood95]

The Neutrik socket, as suggested by Joe Golden will work, as would a
TRS jack. If you go down the TRS route, I should advise using 1/4"
B-gauge jacks, if they will fit in the available space. Some varieties
of jack have many switching contacts.

Some DMX devices have a 'TERMINATE' switch fitted.

It is always important that a DMX line is correctly terminated at all
times. Any bifurcation of such a line must be done with a proper
splitter. As has often been pointed out, failure to do this can
produce highly unpredictable resilts.
