70 registers (Display ASCII): PLC send:01 10 00 70 00 03 06 50 32 2E 30 20 20 C0 00
01: Station number of the digital tube screen (RS485 address); 10: Function code, which means to write multiple registers; 00 70: Display register of digital tube screen (ASCI); 00 03: Number of registers; 06: The number of bytes in the data segment
50 32 2E 30 20 20: ASCII character string. This example shows the ASCII character string "P2.0"
C0 00: Two-byte CRC code, This command will display "P2.0"
The digital tube screen returns: 01 10 00 70 00 03 81 D3 example:
(1)01 10 00 70 00 02 04 2D 2D 2D 2D B0 A3. "---" will be displayed, 2D is the ASCI code of the minus sign
(2)01 10 00 70 00 04 08 38 2E 38 2E 38 2E 38 2E 29 BE. All the strokes of "8.8.8.8." will be displayed; 2E is the ASCII code of the decimal point
80 function code (Custom segment): PLC sends 01 10 00 80 00 02 04 6E 79 6D 00 1A 6E
01: Station number of the digital tube screen (RS485 address); 10: Function code, which means to write multiple registers; 00 80: Display register of digital tube screen (ASCI); 00 02: Number of registers; 04: The number of bytes in the data segment;
6E 79 6D 00: ASCII character string. This example represents the ASCII string "YES";
1A 6E: Two-byte CRC code, This command will display "YES"
The digital tube screen returns: 01 10 00 80 00 02 40 20 example:
(1)0110008000020440404040DFEB, “---" will be displayed, 40 is the segment code of the minus sign
(2)01100080000204FFFFFFFFFA5B, All the strokes of "8.8.8.8." will be displayed; FF is the segment code of the decimal point
Parameter setting (manual)
Function keys: SW2 (Menu, up) SW1 (down)
Press SW2 often to enter the menu interface, press again often, the page is in the normal display, address setting, baud rate setting, parity, power-on default display, brightness setting, save and other menus.
In each function menu, add and subtract parameters through SW2 (up) and SW1 (down) respectively.
Baud rate C1-C8 corresponds to 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200
Power-on default display: "d-0" power-on display 0; "d-A" power-on display local address.
Save: select yes/no with the up and down keys, and long press the "SW2" key again to save the parameters, and the menu will automatically jump to the normal display page.

Bought one of the displays, and had no luck getting any of the 'ascii' commands to display anything. I was able to get a few of the modbus examples to work, but most of them didn't do anything either. Requested help from the vendor, and they verified that "the 6 digit meter does not support ASC form". They included the "full" datasheet for the unit, which show no support for changing the color or the brightness via modbus.There is also something wrong with their implementation of the modbus command for 'displaying floating point numbers". The last digit is always one less than it ought to be. So if you tell it to display 1.2345, it displays 1.2344. Decimal location doesn't matter; 123.45 shows as 123.44So, you're not getting the simple ascii protocol at all, the modbus protocol does not support all the commands they claim, and at least one of the commands the support is buggy.
