BTN - Button ID according to the configuration in K-Config
RED
, GREEN, BLUE- Color intensity for each base color. Values are from 0 (No color) to 255 (Full color). Plain buttons that support only on/off light
should ignore values of these parameters (except if all set to zero – same as turning light off).
STATE :
"0" or "Off" (Color parameters can be ignored).
"1" or "On"
"2" or "Slow" for slow blink
"3" or "Fast" for fast blink
RESULT – OK if command has been executed.
“# DEV_ID@RGB ERR 003” should be returned if any parameter exceeds its limits (for example – Button ID does not exist).
Example:
Master Device:
#03@RGB 1,0,255,0,1 CR
Result: Device Application needs to light on its button 1 and set color to Full green.
Device Application response:
~03@RGB 1,0,255,0,1 OK CRLF

Device that implements lit buttons should reply this request and give its button color and state. Device can support full color buttons or just plain on/off
lights.

Write text to LCD # DEV_ID@LCD LCD_ID,”TEXT”CR ~ DEV_ID@LCD LCD_ID,”TEXT”
RESULTCRLF
Device that implements label (LCD) should react to this command and set its “LCD” (or text label).
LCD_ID – Label (LCD) ID according to the configuration in K-Config
TEXT – The text to display in the label (This parameter should be enclosed by quotation marks, character 34 in Ascii)
RESULT – OK if command has been executed.
“LCD ERR 003” should return if any parameter exceeds its limits (for example – LCD with this ID doesn’t exist).
Read text from LCD
#DEV_ID@LCD? LCD_IDCR ~DEV_ID@LCD LCD_ID,”TEXT”CRLF
Device that implements label (LCD) should react to this command and set its “LCD” (or text label).
LCD_ID – Label (LCD) ID according to the configuration in K-Config
TEXT – The text to display in the label (This parameter should be enclosed by quotation marks, character 34 in Ascii)
Restore User Interface
#01@UI DEVICE_IDCR ~01@UI DEVICE_ID OKCRLF
After answering OK, the master will send to the device commands to refresh user interface elements like RGB buttons and LCD labels.
For example:
#DEV_ID@RGB 1, RED, GREEN, BLUE, STATECR
#DEV_ID@RGB 2, RED, GREEN, BLUE, STATECR
…(All RGB)
#DEV_ID@LCD 1,”TEXT”CR
#DEV_ID@LCD 2,”TEXT”CR
…(All LCD)
Use this command to get the current user interface state on program start or refreshing the GUI.
