Cable shield connection questions
Hello,
It is pretty cear from the DMX spec that a transmitter must have <20Ohm between shield and chassis and a receiver (non isolated) must have 100Ohm.
This is cool BUT what if a device can be a RDM controller AND a RDM responder, depending on the mode?
Is it expected to switch in and out a 100Ohm resistor?
If it needs to be switched, is there a way to do it without a relay?
Kind regards
Bernt
