DMX signal connecting
PX715 have to be connected to DMX line in serial mode, with no branches
on DMX control cable. That means that DMX line, from the signal source,
must be connected to
DMX IN
pins of PX715 and later, directly from
DMX OUT
pins to the next device in DMX chain.
If the PX715 is the last DMX chain receiver there should be terminator
(resistor 120 Ohm) mounted between "
DMX+
" and "
DMX-
" pins of
DMX OUT
section.
