4-6 OPERATION CHAPTER 4
DN-109NE, DN-119NE, DN-129NE and DN-189NE display series
4.3.3.1. Function 06h.
It allows to use integers with or without sign. The address sent determines if the values are
signed or unsigned.
Parameter 1 can be equal to 1 or 2. See 4.2.3.1
“Parameter 1:Protocol”.
Address 40003 (02h) ........... Signed integer. - 32767 to +32767
Address 40007 (06h)........... Unsigned integer. 0 to 65535
In this example the identifier has the value 01C9h and the value to write is
–4096.
Block to send:

Response from the display:
The response from the display is the same block received.
4.3.3.2. Function 10h mode Word
It allows the user to send blocks with ASCII characters to the display
Parameter 1 must have value 2. See 4.2.3.1
“Parameter 1:Protocol”.
In the block, the following values must be codified:
Unit = 01h
Function = 10h
It allows to use integers with or without sign. The address sent determines if the values are
signed or unsigned.
Address 40003 (02h) ........... Signed integer. - 2147483647 a +2147483647
Address 40007 (06h)........... Unsigned integer. 0 a 4294967295
The Data field must contain 3 Words. The two first fields must contain the Data and the third
must contain the position of the decimal point
Value 0001h for 00000000,0 Value 0010h for 0000,00000
Value 0002h for 0000000,00 Value 0011h for 000,000000
Value 0004h for 000000,000 Value 0012h for 00,0000000
Value 0008h for 00000,0000 Value 0014h for 0,00000000
