T5L Display Modbus Tutorial: UART 4, Slave, TTL

Modbus is not so complex than your imagination. At least, i mastered it quite well based on the continuous learning. I'm sales.
Here is the testing parameters:
Model No.: DMG10600C070-03WTC
Signal Interface: UART 2: TTL/RS232;UART 4: TTL/RS232
I use TTL for the test
Also you can see how to connect the wire, what files you need to download;
Function test:
1)send data to the display;
2)read data from display;
3)change display page;
Open for the display sample for the testing.
