Power Input
The PPC-A55-190 Industrial Panel PC can be powered by a wide range of input voltages:
From 12V 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 in the gure
below.
Power Input
Note that the “+” sign represents the positive power input, it is printed at the casing and as a
silk-screen on a PCB of the embedded version. The “-” terminal is shorted to the ground.
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

Touch Screen
The PPC-A55-190 Industrial Panel PC uses a 10-point capacitive touch screen. However, the
Debian OS supports only One-Point touch.
The gure below shows the capacitive touch screen connected to the motherboard via the
USB connector.
Figure 634: Capacitive Touch Connector
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-A55-190 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 problem 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.

Attention
The 120Ω match resistor for CAN bus is NOT mounted by default.
The 120Ω match resistor for RS485 is already mounted by default.
This product supports changing 2 x RS485 to 2 x RS232, supports changing 2 x CAN to 2 x RS232, providing up to 6
x RS232 (including one debug port).
The GPIO has been optical isolated and it uses the 24V logic by default. You can use an external isolated power
input but the power input range should be from 5V to 24V DC.
The 4 GPIO output channels can drive at most 500mA current on each channel.
