ATM…
It is available both as an embedded solution and as a device hosed in an aluminum casing
with bezels, thus facilitating dierent installation options:
Installation on an industrial cabinet
Integration with the existing equipment
The PPC-A72-101 Industrial Panel PC is based around the powerful CS-SOM-RK3399 System
on Module (SoM), powered by the Rockchip RK3399 low-power processor which integrates a
dual-core Cortex -A72 and a quad-core Cortex -A53 with a separate NEON coprocessor.
The RK3399 supports multi-format video decoders and has a high-performance dual-
channel external memory interface (DDR3/DDR3L/LPDDR3/LPDDR4) capable of sustaining
demanding memory bandwidths. It also provides a complete set of peripheral interfaces.

Power Input
The PPC-A72-101 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 on the gure
below.
Figure 411: 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.

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.

Touch Screen
The PPC-A72-101 Industrial Panel PC uses a 10-point capacitive touch screen.
Figure 412: Capacitive Touch Screen 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-A72-101 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 the RS485 and CAN bus is NOT mounted by default.
This products support change 2 x RS485 to 2 x RS232 and support up to 5 x RS232 (include one debug port).
The GPIO Connector is optional. You can Contact us if you need it.
The GPIO has been Opt-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 output channels can drive at most 500mA current on each channel.
