== A complete IR code consists of ... ==

A complete IR code is concatenated from a header + unit address + key code.

=== Header ===

The header starts an IR code and alerts the IR receiver to give it a chance to wake up.

=== Unit address ===

The unit address ensures that only our players react upon receiving IR signals from our [[Remote control|remotes]].

All our remotes use the same unit address: 0x7689 (remote internal representation (1): 0x6E91)

=== Key codes (complete list) ===

(1) SC's and remote internal representation of a key code is reversed and inverted. See next section.

Used key codes (looking at the remote internal representation):

00FF-20DF, 23DC, 2AD5, 2ED1, 3AC5, 3EC1, 44BB-47B8, 4AB5, 4EB1, 51AE-56A9, 5EA1, 609F-639C, 708F, E11E, F10E

== What happens if you press and hold a key? ==

There are two ways to repeat a key code.

=== The complete IR code is repeated over and over again ===

This mode is also called '''continuous''' command transmission mode.

This method repeats the complete IR code (header, unit address and key code) over and over again.<br>
SB3/TR remotes are using this way to repeat a key code.

H+UA+KC - H+UA+KC - H+UA+KC - H+UA+KC - H+UA+KC - H+UA+KC

'''Example''' - add (+) pressed and hold (using remote internal key codes)

H+0x6E91+0x06F9 - H+0x6E91+0x06F9 - H+0x6E91+0x06F9 - H+0x6E91+0x06F9 - H+0x6E91+0x06F9 - H+0x6E91+0x06F9

H: Header<br>
UA: Unit address<br>
KC: Key code

=== The complete IR code is only sent once followed by a special repeat header ===

This mode is also called '''one-shot''' command transmission mode.

This method only sends the complete IR code once, then sends a special repeat header.<br>
Boom remote is using this way to repeat a key code.

H+UA+KC - SRH - SRH - SRH - SRH - SRH

'''Example''' - add (+) pressed and hold (using remote internal key codes)

H+0x6E91+0x06F9 - SRH - SRH - SRH - SRH - SRH

H: Header<br>
UA: Unit address<br>
KC: Key code<br>
SRH: Special repeat header (timing: 9ms mark, 2.2ms space, 0.6ms mark, 96ms space)

BTW: The special repeat header is '''not''' the key code for the key labeled 'repeat' on our remotes. It is a much shorter sequence and has no hex representation.

=== Why we prefer to have the complete IR code repeated over and over again ===

To do a factory reset on SB3, TR or Boom we ask the user to press and hold the add (+) key while powering up the device. Now if you use a SB3/TR remote the add key code is received as soon as the device is able to read from the IR receiver and all is good, a factory reset is done.

However if a Boom remote is used the only code the device 'sees' when it is ready, is the special repeat code which does '''not''' tell about what key was actually pressed and held and '''no''' factory reset is done.
