Construction:
IR-Reader is constructed from sampler, power supply, communication wire, and PC program. The following diagram shows this construction.

Setup:
Program run under Win98, WinMe. Win2k, Winxp, the minimum request is 166MHz with 32M of memory, please extract the ZIP file to a new folder, then find out IRReader.exe and create a shortcut of it. 
Step 1. connect the sampler to serial port of computer by serial communication wire, you can connect it to COM1 or COM2, plug in 9 volt power.
Step 2. Running IRReader, change to "options" page, select communication port according to which port you have connect to,. Then click the "ON/OFF" button above the Top-right window and make it on ( the light bright), then the machine into receiving status.
Step 3. Select "38K far distance" in "receiving mode".
Step 4. Transmit an IR signal to sample by any IR remote controller, the waveform of signal can be seen on the window, if not, please check the communication wire and port are right or not.

Features of Software:

1.Open . Open and save button, save waveform as IR-Reader format.
2.Zoom.Zoom in, Zoom out, Original size.
3.Normal Mode. 
4.Measure Mode. There are two vertical lines on the waveform window, called AB test lines . press the left button of the mouse to set A line place, press the right button to set B line place. The time between A and B is showed at the number 20 on the figure above . For example 14950 us 
5.Help messages.
6.About.
7.ON/OFF switch.
8.Mode. there are 4 channels, each has 6 kinds of working mode. 
    a. Forbid: In this mode doesn't receive any kind of wave form .
    b. Sampler: In this mode only receives the waveform from the sampler machine.
    c. History:  in this mode only receives the waveform from the history record.
    d. File: In this mode only receives the wave form from the file.
    e. Favorite: In this mode only receives the waveform from favorite.
    f: Scroll: receives all kinds of wave form , the waveform is showed by scrolling in the channel which has been set to scroll mode . For example .the channel 1.2.3has been set scroll mode, so the signals from the sampler  -> channel 3 ->channel 2->channel 1.
9.AB test lines.
10.Communication port.
11.Time Out Range: 1 ms--4 000ms
12. Average error time : 
13.Inverse waveform.
14.User Definition options : let the users define the methods of decoding . we will introduce the ways of setting detailed later.
15. Receiving Mode.
    a. 38K far distance mode: Use this mode usually, by 38KHz receiver , the distance can reach to 10m.
   b. Not 38K near distance mode: By photodiode, can test carrier from 0Hz to 120KHz, the 2cm distance has the best effect.
   c. No carrier near distance mode: used to receive the remote control signals without carrier.For example: M708 format, the 2 cm distance has the best effect.
  d. Carrier frequency test: In this mode, IRReader can read the waveform of the carrier, like the follow figure:

16. Color options: you can define the color you like 
17. History records :keep 500 newest signal notes voluntarily, Through the history records windows you can review the signal waveform easily.
18.Files: Easy to browse waveform on harddisk.
19.Favorite: you can save the important wave-form in it:
      (1)Drag the waveform into it by the left button.
      (2)Click the right button of mouse then select "Add to Favorite".
20. Hint: show Time of pulse, time between AB lines.

21.Methods of decoding for TV Set. include more than 70 kind of formats.

22.User definition decode show here.
23.Modulus:
Timing modulus ,the rate between the .frequency of using crystal in standard circuit and the frequency of the using crystal in reality circuit ,generally set 1.0 . For example: the frequency of crystal which a  remote control IC Standard circuit is 455KHZ, but some factories use 420KHZ ,cause the width of pulse enlarged to scale, the timing modulus is 455/420=1.083 at the time 
24.Auto Search:
For the unknown waveform, it can discern and decode the coding voluntarily , Because the timing time of some coding are very close, so errors will happen sometimes, you can disable this function and select a fix decode method.
Specification 

How to share waveform?
Waveform can be saved as BMP or JPEG format, also can be opened in other program, convenient for browsing . Ways: click the right button select "Save as BMP file".

It also can be save as IRReader own format, it only can be opened by IRReader on another computer, this format is more easy for browsing. 
Ways: click the "Save" button then select "Save channel 1/2/3/4 to". If you want to open the waveform file, please click the "Open" button then select "Open to channel 1/2/3/4".

How to setup user definition?
Most of the IR remote controller code by width of pulse. the "user definition methods" allow the users to define the methods of decoding ,for the unknown formats.


*Name
You must create a new method First, then input a name you want.

*Low and High pulses of leader code.
The leader code consists of a low and a high pulse, the low ahead, the high behind, the unit is us, generally more than 100 us, not have to input the unit, for example set 1000 us, it is just ok to input "1000"directly, If no leading code, both are set to "0".

* Low and High pulses of Bit 0/1.
A bit O/1 is also consists of a low and a high pulse, the low ahead, the high behind, the unit is us ,generally, more than 100 us, not have to input the unit ,For example set 1000 us ,it is just OK to input "1000" directly.

*Error range.
Allow some error for time of pulse when decoding, for example low pulse of bit 0  is set "500",high pulse is set "1000" , error is set "200", means when low pulse that between 300us and 700us,high pulse between 800us and 1200us, will be decoded to bit O.

*Partition

Generally, a frame of signals consists of leader code ,custom code, data ,etc, each of them consists of some bits, they will be showed separately when showing the results of the decode, for example "8,8,8,8",means a controller consists of 8 bits custom code, 8 bits inverse code of custom code. 8 bits data and 8 bits inverse code of data. Each must be more than or equal to 1,less than or equal to 32, divided by ",".

*LSB first
Means that low bit sent first, otherwise high first.

*Ignore error bit 
A frame of signals contain some bit that neither belong to 0 nor 1 sometimes, we must ignore them and go on decoding, for example M50560, there is a separation bit signals, neither belong to O nor 1, if this checkbox has been selected, it can be decoded normally, if don't selected, it will show the wrong information when decoding.
