3.3 DMX wiring
The JBLED A7 has 3pin and 5pin XLR connectors for DMX-in and DMX-out.
Do not connect more than 1 data input an 1 data output on a fixture.
Connect the DMX-out of the control desk to the first JBLED A7 in line. (lighting control
desk DMX-Out / JBLED A7 DMX-In). Connect the second JBLED A7 to the first in line,
and so on (JBLED A7 2 DMX-In / JBLED A7 1 DMX-Out). All 3-pin and 5-pin connectors
are wired parallel.
Do not use this fixture as a DMX splitter!
The DMX-Out of the last unit in line is not occupied unless problems occur.
Then use a termination plug with the last JBLED A7 in line.(XLR-connector with a 120
Ohm resistor soldered between pin 2 and pin 3). Problems might occur when the line is
overloaded, e.g.

Use a shielded twisted-pair cable with two pairs to connect the serial link. Connect
all pins if you want to upgrade the software in crossload.
If a microphone cable (or any other cable with only one pair) is used the software
can not be updated via DMX line because pin 4 and 5 are not connected.
Pin assignment
Pin 1 = shield
Pin 2 = data -
Pin 3 = data +
Pin 4 = data out -
Pin 5 = data out +
