Capacitive Touch

The  product  CS19108R125P-C111  uses  a  ten-point  capacitive
touch.

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.

DB9 Connector

There  are  6*DB9  connectors  configured  as  RS232  by  default.
COM3/COM4/COM5/COM6 can be customized to RS485. If you need
any  other  setting  different  from  the  default  one,  please
