Note A
: 1. Adopting the 8 Pin 2mm spacing socket.
2. Direction of the signal was defined with TFT-LCD Module;
“I” refers to the signal from the user’s system transmitted to the TFT-LCD Module.
3. Pins with the same definition are connected together in the module inside.
4. User can set the RS232 or 3.3 V TTL/CMOS level by soldering pad on the PCB.
Default is “OFF” (RS232 Level). If change to “ON”(TTL Level), only need to short
the soldering pad of J21, J22, and take out R60.
5. The RS485 and other interface can be customized which need to point out in the
order.
6.”Busy” signal doesn’t need to be considered as communication, Frame and
Command never be lost, (200MHz CPU,1M bit Command Buffer), “BUSY” signal
can be accessed to data input pin or left vacant.
