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.
