Touch Screen

The PPC-A76-070 Industrial Panel PC uses a 5-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:

  1. Use a high-quality Power Adapter Unit (PSU) with low EMR. You can also provide power from a battery.

  2. Make sure that the PPC-A76-070 Power Input connector (pin 3) is properly connected to the Power System Ground to provide sufficient EMI shielding and eliminate the problem entirely.

  3. 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-A76-070 industrial PC. It has 2 x USB 3.0 HOST, 1 x USB Type-C, 2 x RJ45, GbE (RJ45) Ethernet connector supporting up to 1 Gbps, and 5 x UART terminals (RS232/RS485), 2 x CAN.

RS232/RS485/CAN

The serial communication interfaces (RS485, RS232, and CAN) are routed to a 16-pin 3.81mm terminal, as illustrated on the figure below.

GPIO

The PPC-A76-070 Industrial Panel PC features a 10-pin 3.81 mm terminal that provides 8 x opto-isolated GPIO pins, of which 4 x are output, and 4 x are input pins. The 10-pin terminal also includes an isolated PSU input in the range of 5 to 24 VDC. The exact pinout is given in follow table.

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. Each GPIO output can drive loads up to 500mA, enough to drive various applications directly, such as relays or solenoid valves.

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.
Note that in this case, the Isolated Power Input pin will become an output for the onboard 5V power supply.

TF Card Slot

The PPC-A76-070 Industrial Panel PC features 1 x TF Card (micro SD) slot. TF Card can address up to 128GB of storage.
