HDMI5 Component Video Switch

Extended Control Settings

In the Asynchronous mode of operation, the HDMI5 will transmit state changes as they occur. 

This command allows individual control over which state changes will be sent.
This HDMI5 allows control over the following states:

Power State changes (On / Off condition).

Selection changes (input / output mapping changes).

Front Panel modes and intensity changes

Front Panel Button Presses.

IR codes received.

New IR codes learned.

Control Settings changes.

Each of the above  states can be selectively set to asynchronously transmit their state changes, 

or run in the Master / Slave mode. If asynchronous transmit has been disabled for one of the 

options, then that option will revert to the Master / Slave mode.

The ‘AS’ in the 

“Control Settings”

 command must be set to ‘1’ to allow any Asynchronous 

transmissions, if the ‘AS’ bit is set to zero, then the HDMI5 will operate solely in the Master / 

Slave mode regardless of the settings of this command.

PWR - 1=Power State has changed.

SEL  - 1=Selection (Input / Output Mapping) has changed.

BTN  - 1=One or more buttons have been pressed.

IRR  - 1=A new IR code has been received.

IRC  - 1=New IR codes have been learned.

LMI  - 1=Lighting Mode or Intensity Level Settings have changed.

CTL  - 1=Control Settings have changed.

SWD - 1=Switching delays have changed.

EQU  - 1=Equalization or Bandwidth settings have changed.

RL1  - 1=Auxiliary 1’s relay has changed states.

RL2  - 1=Auxiliary 2’s relay has changed states.

RS1  - 1=Auxiliary 1 relay’s parameters have changed.

RS2  - 1=Auxiliary 2 relay’s parameters have changed.

The ‘$’ parameter is a “Backup Control Settings” flag. If it exists, then the current settings will 

be backed up in EEPROM, and will remain unchanged through a power failure. Backing up the 

Extended Control Settings
