Infrared-RAW Definition 
In case the IR-Codes in the mpi-file are defined as 
RAW-Daten a detailed decoding of the IR code is 
necessary. 
RAW-Datas define an IR-Code based on: 
- Carrier frequency (IR_CARRIER) 
- Repetition Pause (IR_PAUSE) 
- Repetition Rate (IR_REPEAT) 
- Impuls-/ Pause-Duration (IR_TIMEx) 
A typical IR-code is built as follows: 
  ⇑  ⇑ 
Impulspackage with startbits Repetition 
In the mpi-file these 4 declaratoins are being used. 
Only whole-numbers can be used. 
IR_CARRIER  [kHz]  : Value 1-450 
IR_PAUSE  [ms]  : Value  1-65 
IR_REPEAT    : Value  0-65 
IR_TIME  [µs] : Value 1-65535 
IR_TIME 1   
IR_TIME 2 
IR_TIME 3 
IR_TIME … 
IR_CARRIER 
IR_CARIER is the carrier frequency of the IR signal in 
kHz. The maximum frequency is 450 kHz. Higher 
frequencies can not be processed. 
IR_PAUSE 
IR_PAUSE defines the pauses between the first 
impuls package and the repetitions, in case the button 
is pressed for a longer time or IR_REPEAT is greater 
than 0. 
IR_PAUSE
IR_TIME 
The IR_TIME defines the Impuls- and pause duration 
of a IR-Code. Different times can be defined here. It is 
not defined whether the defined time is being used for 
an impuls or a pause as IR_TIME only defines the 
time elapsed between flanks. 
In the following chart a IR-impuls is shown it becomes 
visible that the IR_TIME_1 is existing as a pause and 
also as an impuls. 
Example: 
IR_TIME x
1234
IR_TIME_1 = 540 
IR_TIME_2 = 1570 
IR_TIME_3 = 4130 
IR_TIME_4 = 8420 
IR_REPEAT [ > ] 
IR_REPEAT defines how often a repetition of the IR-
code shall take place. The repetition is defined in the 
mpi-file with sign >. All figures (IR_TIME x), which are 
on the righthandside of the > Symbol, will be 
recognized as a repetition code. 
Exception 
IR_REPEAT = 0 
The repetition code will be repeated as long as the 
button (Soft- or Hardkey) will be pressed. 
Toggle-Code 
A Toggle-Code changes the Code with each press of 
a button between two values. 
This way the long pressing of a button (e.g. several 
times sending the volume up command) can be  
differentiated from pressing a button several times 
(e.g. channel 11). The M208 can generate such 
commands in case two commands have been defined 
in the mpi-file for each button (Hardkey or Softkey). 
Syntax 
Name (Soft- Hardkey) =  “Code 1, Code 2“ 
Example: 
Power = "2211 1111211211, 2112 1111211211" 
IR-Code Description in the mpi-File 
POWER
_
ON = "43 > 1212111111111"
