Product Overview¶

The Cortex^®-A72/53 series EPC/PPC-A72-070-C (PN: CS10600R070) is a high-quality industrial panel PC. It features a 7.0” five-point capacitive touch screen with a resolution of 1024 x 600 pixels and brightness of 500 cd/m².

It is available both as an embedded solution and as a device hosed in an aluminum casing with bezels, thus facilitating different installation options:

Installation on an industrial cabinet
Integration with the existing equipment

The EPC/PPC-A72-070-C 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 EPC/PPC-A72-070-C 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 figure below.

../../../../../_images/Power.jpg — Figure 392: *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.

Table 91 Power Connector¶
Power Input Definition
Pin Number	Definition	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 EPC/PPC-A72-070-C Industrial Panel PC uses a 5-point capacitive touch screen.

../../../../../_images/TS_CON1.jpeg — Figure 393: *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 EPC/PPC-A72-070-C 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 problem 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 EPC/PPC-A72-070-C 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, and 7 x UART terminals (RS232/485).

RS232+RS485 Connector¶

The serial communication interfaces (RS485 and RS232) are routed to a 16-pin 3.81mm terminal, as illustrated in the figure below. Serial communication on both RS485 and RS232 interfaces can reach up to 115200 kbps.
