Using Discrete IR Codes
The UltraRes display accepts commands in the form of IR signals that conform to the
NEC protocol. Each UltraRes remote control has an NEC control code associated with
it. You can use these codes to program a third-party “universal” remote control to
work with the UltraRes. These third-party products usually come with a computer
software application for this purpose. For more information, consult the
documentation provided with the remote control.
IR Command Protocol
The IR control codes have the following characteristics:
• Each code consists of the following:
• A leader pulse (a modulated pulse of 9 ms followed by a non-modulated
pulse of 4.5 ms)
• 16 address bits. The default address is 1785 (0x06F9, binary 00000110
11111001)
• 16 data bits: eight (8) bits for the command followed by the logical inverse
of the command
• An end pulse (a modulated pulse of 0.56 ms, similar to the modulated
pulse in the ‘0’ and ‘1’ bits). The end of the modulated pulse constitutes the
end of the data transmission.
• The carrier frequency is 38 kHz, with the modulated pulses having a 33% duty
cycle.
• Commands are sent at a maximum rate of 9 Hz.
For example, below is the NEC control code for the ON button of the UltraRes remote
control (assuming the default address is used).
The following example shows the pulse train for this command.
