APPENDIX B

The 8X8 DVI Matrix uses RS-232 serial communication for access to a number of features. Please us this section for EDID storing, calling, and routing functions.

REMOTE FUNCTION

The remote functions are used to modify the setting of the product, such as: Input to output routing, EDID memory management etc. These functions are available only by the serial communications port.

Modify By Shortcut

Switching Command

First character indicates the output monitor. Second character indicates the input number.

Example: ‘A5’ routes input 5 to output monitor A

Matrix Status Command

The ‘M’ or ‘m’ command will return the current routing state.

Shortcut Routing Command

This command sets the matrix routing state according to a preset routing state. First character is ‘S’ or ‘s’, second character indicates the state that is set by

function #PSASRS or #MSASRS (please see page##)

Setting Function Menu

The ‘P’ or ‘p’ command will return the settings function menu.

Modify By Function

The syntax for each function is always the same. The ‘#” character is the start flag followed by the function name in capital letter and a space. The space tells the MCU that the function name is ending. Finally, the parameters required for each function are separated by a space and ending by the ‘\r’ character or “Enter”

Example: #FunctionName_param1_param2_param3_param4…\r

RMT-16-IR Address

This function set the remote channel that must match the GEFEN RMT-16-IR remote control.

#RMT_param1\r
