The PX268 must be connected to the DMX line in a series, without branching on the control cable.
This means that the DMX IN pins in PX268 must be connected with the control cable.
From the DMX OUT pins it must be led to the next DMX receivers.

5. CONNECTION SCHEME
Due to use of passive-type DMX in the PX268 driver, a 120 Ohm terminator is needed at the
end of DMX line. Such a solution allows to connect up to 32 of the PX268 drivers to a DMX
controller (serial connection).
The connections have to be made with wires of appropriate gauge. The proper connection
lowers the risk of damaging the driver and improves its reliability. For DMX signal connection
use the shielded conductors only.
