Power Input
The PPC-A55-050 Industrial Panel PC can be powered by a wide range of input voltages:
From 6V to 36V DC. The power input connector is a 3-pin, 3.81mm terminal. The polarity
and the pinout is clearly marked on the housing of the product as shown on the gure
below.
Figure 564: Power Input
Note that the “+” sign represents the positive power input, and it is printed both at the
casing and as a silk-screen on a PCB of the embedded version. The “-” terminal is shorted to
the ground.
Touch Screen
The PPC-A55-050 Industrial Panel PC uses a 5-point capacitive touch screen.
Power Input Denition
Pin Number Denition Description
Pin 1 Positive Input DC Power Positive Terminal
Pin 2 Negative Input DC Power Negative Terminal
Pin 3 Ground Power System Ground

Note
The system ground “G” is connected to power negative “-” on board.

Connectivity
There are many connectivity options available on the PPC-A55-050 industrial PC. It has 1 x
USB 2.0 HOST, 1 x USB 3.0 HOST, 1 x USB Type-C, 1 x RJ45, GbE (RJ45) Ethernet connector
supporting up to 1 Gbps, and 4 x UART terminals (RS232/RS485/CAN).
RS232/RS485/CAN
The serial communication interfaces (RS485, RS232, and CAN) are routed to a 12-pin
3.81mm terminal, as illustrated on the gure below.
Attention
A capacitive touch screen is susceptible to power noise and Electromagnetic Radiation (EMR). It may cause LCD ripples
or even capacitive touch malfunction. If using a capacitive multi-touch test application, you might notice the touch
points oat erratically across the display. There are several solutions to this problem:
Use a high-quality Power Adapter Unit (PSU) with low EMR. You can also provide power from a battery.
Make sure that the PPC-A55-050 Power Input connector (pin 3) is properly connected to the Power System
Ground to provide sucient EMI shielding and eliminate the problem entirely.
Bad GND problems can also be conrmed by touching pin 3 of the Power Input connector with one hand while
operating the capacitive touch screen with the other hand. In this case, the operator’s body acts as the Power
System Ground.
