OPERATION
4-15
DT-203X, DT-105X and DT-110X display series
Message with variables.
The message number is the two first bytes of the data block. See Message without
variables.
The position and values of variables follow the message number with this format:
Pv
Nc
Dv
Pv: Position of variable.
Nc: Format and character number.
Dv: Variable data.
Pv: Position of variable. 1Byte.
Every line can display up to 16 variable characters.
A display of eight lines can display up to 128 variable characters. (16 per line)
The variable positions are:
Line
Position in decimal
Position in hexadecimal
1
1-16
1h-10h
2
17-32
11h-20h
3
33-48
21h-30h
4
49-64
31h-40h

81-96
51h-60h
7
97-112
61h-70h
8
113-128
71h-80h
A variable position is independent of used variables, this means that although no
variable is used in line 2, the first variable on line 3 is in position 33.
The variable position must be in hexadecimal code.
Nc: Format and character number. 1Byte.
