EA KIT120-5
ESC
This command suspends the KIT for n1/10 seconds.
Example:
$1B $58
After this command the KIT waits for a second before the next command is processed.
ESC
Reads in the input port (n1=1..5 = IN1..IN5). When n1=0, all the inputs are read in as 5-bit binary values
(MSB:IN5...In1:LSB); see application on page 5. Important: The optocouplers invert the input logic (input open: 1).
The „ESC Y I 1“ command puts this right (input open: 0).
Example:
$1B $59
Reads in port IN3. The result is sent via RS232.
ESC
Changes the output port (n1=1..5 = OUT1..OUT5) 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:OUT5...OUT1:LSB); see application on page 5.
Example:
$1B $59
Switches the output port OUT2 to high level.
ESC
Each change at the input port (5-bit binary value IN5..IN1) can call a port macro (0..31). 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 $59
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 $59
Inverts the input port logic.
ESC
The LED backlighting is switched off (n1=0), switched on for an undefined period (n1=1) or inverted (n1=2): on->off
or off->on or switched on for n1/10 seconds with n1=3..255.
Example:
$1B $4A
The LED backlighting comes on for 10s after this command.
