ESC
Changes the output port (n1=1..8 = OUT1..OUT8) to the value n2 (0=low level; 1=high level; 2=invert port). When
n1=0, all the outputs are output as a binary value n2 (MSB:OUT8...OUT1:LSB); see application on page 5.
Example: $1B
Switches the output port OUT2 to high level.
ESC
Each change at the input port (8-bit binary value IN8..IN1) can call a port macro (0..255). This command
activates (n1=1) or deactivates (n1=0) the automatic port query. After power-on, the current port status is read
and the associated port macro executed immediately.
Example: $1B
Activates the automatic port query and executes the associated port macro.
ESC
This command allows the logic of the input port to be inverted (n1=0 for normal or n1=1 for inverse). This is
useful with the optocoupler inputs, for example.
Example: $1B
Inverts the input port logic.
ESC
n1=0 switches backlight off and n1=1 will switch on backlight permantly; n1=2 switches B./L. from On->Off and
from Off->On. n1=3..255 switches B./L. on for a periode of n1/10 seconds. Is a resistor (e.g. 47 ohms) is
inserted at R
Example:
will switch on backlight for a periode of 10 sec.
ESC
Writes the string text... left justified (L), centered (Z) or right justified (R) at position
x1 taking into account the set text mode (ESC L). Multi-line text can also be output,
with the lines separated by the character '|' (=$7C). The string must be concluded with
NUL= $00. Position y1 is the upper edge of the 1st line.
Example 1: Writes the text "Left|Ok" left justified at 0,0.

Example 2: Writes the text "Center|Ok" centered at 25,0.

Example 3: Writes the text "Right|Ok" right justified at
49,0.

ESC
Writes the string text... rotated by 90° degrees top justified (O), vertically centered (M)
or bottom justified (U) at position y1 taking into account the text mode (ESC L). Multi-
line text can also be output, with the lines separated by the character '|' (=$7C). The
string must be concluded with NUL= $00. Position x1 is the right edge of the 1st line.
Example 1: Writes the text "Top|Ok" top justified at 49,0.
$1B $5A $4F $31 $00 $54 $6F $70 $7C $4F $6B $00
Example 2: Writes the text "Mid|Ok" vertically centered at
49,15.
$1B $5A $4D $31 $0F $4D $69 $64 $7C $4F $6B $00
Example 3: Writes the text "Bot|Ok" bottom justified at
49,31.
