VP-773AMP - The VP-773AMP RS-232 Communication Protocol

The “Y” command also supports the value increment/decrement of any command

using the ‘+’ or ‘-‘ signs as the third parameter of the “Y” command.

For example, move the PiP window one step to the left

Send: “#Y 0,141,-,1<CR>”

Reply: “~01@Y 0,141,-,1 OK”

For example, in order to increase zoom on the main window

Send: “#Y 0,650,+,0<CR>”

Reply: “~01@Y 0,650,+,0 OK”

12.2.2 Using the Communication Protocol with Legacy Protocol

Set Command:

Type in: YControl_TypeFunctionParam[CR]

Reply: ZControl_TypeFunctionParam[CR][LF]

Get Command:

Type in: YControl_TypeFunction[CR]

Reply: ZControl_TypeFunctionParam[CR][LF]

When sending a command, a blank character may precede [CR] if desired

Example:

Example 1: set brightness value as 32

Send: Y041032[CR]

Reply: Z141032[CR][LF]

Example 2: get current output resolution. (4 = SVGA)

Send: Y1631[CR]

Reply: Z16314[CR][LF]
