10 VP-724xl Communication Protocol

Set and Get command:

Set Command: Y￿Control_Type￿Function￿Param￿CR

￿Reply: Z￿Control_Type￿Function￿Param￿CRDone>CR Get Command: Y￿Control_Type￿Function￿Param￿CR ￿Reply: Z￿Control_Type￿Function￿Param￿CR

Example:

1."Y￿ 1￿17￿0-127￿CR" -> set Contrast value. (4th byte is between 0 and 127).

"Z￿1￿17￿0-127￿CR>" --> Reply value "DoneCR" --> command setting success

2."Y￿4￿21￿0-17￿CR" -> get current output resolution. (4th byte is between 0 and 17).

"Z￿4￿21￿0-17￿CR>" -> Reply value

3."Y￿0￿35￿CR" -> Volume down. Each time we apply this command will decrease the volume level by one step. "Z￿0￿35￿CR>"-->Reply value

"DoneCR" --> command setting success

Definition:

￿: ASCII Code 0x20

CR: Ascii Code 0xD or 0xA
