Scheme connection of multiple panels PX181 and Px140 controller:
The panels should be connected on a serial basis, with the last panel being finished with a 120
Ω
terminal (insert a resistor with 120 Ω resistance between the positive pin and the negative pin).
Even if you want to connect just one PX181 panel to PX140, it is necessary to insert the
120
Ω terminal.

For communication between PX140 and PX181 and also between touch panels connected in
series, use screened twisted pair cables with impedance of 120
, e.g.
• RS 485 LAPP UNITRONIC® LiYCY (TP) paired 2 x 2 x 0.14
• LI2Y(St)-CY 1x2x0,22mm2 120
For the purpose of connecting the device, you can also use a twist cable and, in that case,
you need to connect the white-and-orange colour of the cable as a plus (+), and the orange
colour as a minus (-); and the white-and-brown colour as the screen.
