1(1,2)This product has 4 x UART by default, 6 x UART channels at most. The default conguration is 2 x RS232 and 2

x RS485, including 1 RS232 debug port. The 2 x CAN can be congured to RS232. UART can be swapped

between RS232 and RS485 modes easily, if you need a dierent RS232/RS485 conguration, please get in touch

with the Chipsee Technical Support at [email protected]

Power Input

The PPC-A55-215 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.

Touch Screen

The PPC-A55-215 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 612: Capacitive Touch Connector

Connectivity

There are many connectivity options available on the PPC-A55-215 industrial PC. It has 1 x

USB 2.0 HOST, 1 x USB 3.0 HOST, 1 x USB Type-C, 1 x network connector (RJ45) supporting

up to 1 Gbps, 8 x GPIO, 2 x CAN and 4 x UART terminals (RS232/485).

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-A55-215 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.

RS232+RS485+CAN+GPIO Connector

The serial communication interfaces (RS485, RS232, and CAN) are routed to a 24-pin

3.81mm terminal, as illustrated in the gure below. Serial communication on both RS485

and RS232 interfaces can reach up to 115200 kbps.

Table 146 Connectivity Section

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.
