PXM PX165, Руководство пользователя, Страница: 6 / 12

4 DMX signal connection
PX165 have to be connected to DMX line in serial mode, with no branches
on DMX control cable. That mean that DMX line, from the signal source, must
be connected to
DMX IN pins of PX165 and later, directly from DMX THRU pins
to the next device in DMX chain.
If the PX165 is the last DMX chain receiver (there is no connected receiver
for the DMX THRU output), it is necessary to shorten 120R pins – the bridge
on these pins will act as a terminator (120 Ohm resistor).

Each of the six splitter outputs is treated as the start of a new DMX line.
A maximum of 32 devices can be connected with the DMX line, with the length
up to 500 meters. In the last device of each DMX output line it is necessary
to connect the terminator.
