The product CS14900F190P-C111 uses a wide-range power input DC 15~36V. The total power consumption is normally about 22W. The Power Input Connector is 3 Pin 3.81mm Screw Terminal Connector as Figure 3 shows. 

A detailed description of the power input connector pins is provided in Table 1.

ATTENTION:

The system ground “GND” has been connected to power negative “-” on board.

The product CS14900F190P-C111 uses a ten-point capacitive touch.

ATTENTION:

Capacitive touch is very sensitive to power noise. Ripple voltage/current from the power adapter will cause the LCD ripples, and will also cause the capacitive touch malfunction. If you use the APK Multi-Touch under Android to test, you can find the touchpoint float. There are several ways to solve this problem:

1)  Use a high-quality power adapter. Or a battery to provide power like a cell phone or tablet PC. 

2)  If the power adapter isn’t good enough, make sure the CS12102F170P-C111 power input connector Pin 3 is connected to the Ground. This method can eliminate the problem totally. You can test it by touching the GND of CS12102F170P-C111 with one hand, while the other hand operates on the capacitive touch screen. In this case, the user’s body acts as the Power System Ground.

The CAN+RS485+RS232 connector is a 16 Pin 3.81mm Screw Terminal Connector, as Figure 4 shows. As for the definition of every pin, please refer to Table 2. This product has 5 channels of UART in total that can be freely configured as RS232 or RS485. If you need other settings different from the default one, please contact us.

ATTENTION:

1. UART2 signal has been used by Bluetooth signal onboard. The RS485_2 function has been disabled by default. If you need the RS485_2 function, please contact us to disable the Bluetooth function.  
2. A 120Ohm resistor doesn’t come mounted by default with the product.

There are two dual USB ports, as Figure 5 shows, each provides a 500mA current.
