Power Input Connector
The product uses a wide-range power input DC 15~36V. The total
power consumption is normally about 7.5W. The power input
connector is a 3 pin 3.81mm screw terminal connector, as shown

www.chipsee.com
www.chipsee.com
in Figure 5.
A detailed description of the power input connector pins is
provided in Table 1.

Power Input Pin Definition:
Pin Number Definition Description
Pin 1 Positive Input Connect to DC Power Positive
Terminal
Pin 2 Negative Input Connect to DC Power Negative
Terminal
Pin 3 Ground Connect to Power System Ground
ATTENTION:
The system ground “GND” has been connected to power
negative “-” on board.
Capacitive Touch
The product CS12800R101P/ CS12800R101E uses a ten-point
capacitive touch screen.
ATTENTION:
Capacitive touch screens are very sensitive to power noise.
Ripple voltage/current from the power adapter can cause the
LCD ripples, as well as the capacitive touch malfunction. If
you use the APK Multi-Touch under Android to test it, 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
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 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.
RS485+RS232 Connector
The RS485+RS232 connector is a 16 Pin 3.81mm Screw Terminal
Connector, as Figure 6 shows. As for the definition of every
pin, please refer to Table 2. This product has 7 channels of
UART in total that can be configured as RS232 or RS485 freely.
If you need any other setting different from the default one,
please contact us.
