Touch Screen¶
The PPC-A76-101 Industrial Panel PC uses a 10-point capacitive touch screen.
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 float 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-A76-101 Power Input connector (pin 3) is properly connected to the Power System Ground to provide sufficient EMI shielding and eliminate the problem entirely.
Bad GND problems can also be confirmed 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.
Connectivity¶
There are many connectivity options available on the PPC-A76-101 industrial PC. It has 2 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).
RS232/RS485/CAN¶
The serial communication interfaces (RS485, RS232, and CAN) are routed to a 24-pin 3.81mm terminal, as illustrated in the figure below.
Serial communication on both RS485 and RS232 interfaces can reach up to 115200 kbps.
Attention
The 120Ω match resistor for CAN bus is NOT mounted by default.
The 120Ω match resistor for RS485 is NOT mounted by default.
RS485_3 and RS485_4 can control the input and output direction automatically. There’s no need to control it from within the software.
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).

GPIO¶
The PPC-A76-101 Industrial Panel PC features a phoenix connector that provides 8 x opto-isolated GPIO pins, of which 4 x are output, and 4 x are input pins.
The GPIO HIGH output level corresponds to the voltage connected at the isolated Power Input, while the GPIO LOW output level corresponds to the isolated Ground Input.
The GPIO 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.
Attention
In order to use the Isolated Output, you need to add an external Isolated Power to the VDD_ISO and GND_ISO. The power voltage should not exceed 24V.
The output current can supply 500mA for every channel, but it also depends on the isolated power that is connected.
In order to use the Isolated Input, you need to add a signal to the InputX and GND_ISO. A 2.4KΩ resistor has been added to limit the input current, as shown in the figure below. This resistor should work well for the 5-24V input signal. If your input signal is less than 5V, please change this input resistor. The reduced schematic is for reference purpose, if you need the precise resistor schematic, please contact us.
If the isolation is not a requirement, it is possible to use a non-isolated PSU instead. It is also possible to use the onboard 5V power supply: it can be re-routed to the Isolated Power Input pin by populating two PCB resistor footprints with 0Ω resistors. In this case, the Isolated Power Input pin will become an output for the onboard 5V power supply.
