HDMI5 Command Ref. (Cont'd)
keep the size of the IR response small, this command sends the 72 bit IR code as an 18 digit
hexadecimal value.
IR ?
Query for the IR code of the last IR command received.
IR
Query for the IR code of the last IR command received.
Response String:
=IR ircode
Where:
ircode = 18 hex digits (0-9, A-F), representing the most recent IR code received.
This command returns a single digit '0' if there are no IR codes waiting to be read.
Set Learnable IR Command Codes
This command is used to set, or retrieve, the current IR codes associated with the learnable IR
commands. This is useful for "cloning" the IR codes learned in one HDMI5 into another HDMI5.
IRC ircmd,ircode
Set the 'ircmd' to use the IR code 'ircode'.
IRC ircmd,?
Query for the 'ircode' for IR command 'ircmd'.
IRC ?
Query for all 'ircmd' settings.
Response String:
=IRC ircmd,ircode
Where:
ircmd = IR command number being set / retrieved (See Table).
ircode = 72 bit IR code (See: "IR" command).

Setting an 'ircmd' to 'ircode = 0', causes that command to no longer respond to IR.
IR codes are always saved in EEPROM.
Front Panel Button Emulation
This command allows access to the internal keyboard handling of the HDMI5, and is very hard-
ware dependent. Button values returned by the HDMI5 may and most likely will be different than
button values returned by other Zektor devices.
Each button generates a value upon being pressed, and a different value upon release.
The Power toggle button also generates a unique value when held for 4 seconds, which is used
to enter the setup mode. Other combinations may also generate unique codes.
This command allows the controller to detect front panel button presses even when the front
panel is disabled. This allows the controller very tight control over the HDMI5. By disabling the
front panel (setting the FP bit to '0' in the "Control Settings" command), and by then process-
ing the front panel button presses of the HDMI5, a controller can redefine the operations of the
HDMI5.
