1.How to istinguish original and fakes of PC Analyzer? 
 
      Answer :The intelligent PI0050 、M04 and so on is well compatible with main board from 8088 to P Ⅲ、 PIV . So you can distinguish two-code PC Analyzer regarded as PI0050 by their characteristics as follows, and also you can pay a attention to the information of this web site to get lastest distinguishing messages. Original:  ● There is “China Copyright 01224987.4” on the edge of PCB; ● There is “China Copyright 513427”on PI0049 、 pi0050 、M04 and so on; ● On the back of the PC Analyzer,there is a mobile number of “+86 139 2517 4332”or telephone number of “+86 020 61131568”Since our company has designed originally the first PC Analyzer that it does no harm to the device while inserting in ISA slot wrongly or rightabout, it is most users' favor. But much fakes have been in market at the same time. In order to keep you from swallowing the bait and getting the shaft, the feature of fake that can be offered as follows:   Fake: ● "中国专有号:01223987.3"on the PCB; ● "专有技术:01224988.3"on the PCB; ● "专利号:02125087.5"on the PCB; (It is the patent of biology organic compound). ● Be careful ! The fake PC Analyzer always are made of bad or unsuitable materials. It hasn't been tested by the professional  equipment and hasno simulation technique. At the same time, there may be a few PC Analyzer PI0049 regarded as the PC Analyzer PI0050 to sell.
 
2.Why is none or one bit displayed in the digital screeen panel?       
      Answer :As all the two-bit-code PC Analyzer diagnose the main board by BIOS (refered to the "SYNOPSIS" in the chapter one of the manual), the code must not been displayed in such following conditions:

        Ⅰ.The PC Analyzer is inserted in the main board without the CPU      Ⅱ.During the RST LED is lighting (the tested main board is reseting);      Ⅲ.The main board doesn't run although there is CPU inserted in it;  In any condition as above, There will be only one-bit code or no code to displayed automatically on two-bit-code PC Analyzer from PI0049C series to PI0049F series.It has filtered the meaningless "intiative code". But some users didn't know this function and consider by error that PC Analyzer is wrong itself. Four-bit-code PC Analyzer with intelligent structure own the function that it can judge "intiative code " and " trouble code"

 
3.How do we distinguish "intiative code" and " trouble code"?          
      Answer :When conventional two-bit-code PC Analyzer displayed a code, at first, We must see whether there is a series of codes varying before the code is deplayed.If there is aseries of codes varying and it stops at acertain code in the end, the code is the" trouble code"; If the deplayed code is first code and you cannot see any other code varying before it, the code is the" intiative code". The intiative code is meaningless. But sometimes the speed of code varying is too fast on some computer so that by unaided eye we cannot make a judgement whether there is a series of codes varying before it stops at the certain code that I can see in the end. you need consider this code as the “trouble code" here in this condition. If you have not solve the trouble, this code must be the intiative code. Four-bit-code PC Analyzer can thumb through the code that has gone. It is very easy for us to make a judgement that the code that is deplayed is "intiative code" or" trouble code".
 
4.Why is the initiative code meaningless?                              
      Answer :The code that is first displayed when power is on is called intiative code by us.Because the PC Analyzer is also electronical device itself, When the power is on, PC Analyzer will display one two-bit code automatically. It is the initiative code. But the code is not the POST code (refered to the "SYNOPSIS" in the chapter one of the manual) of the computer.So the intiative is meaningless.
 
5 .How is the "initiative code" exactly identified on the PI0050 PC Analyzer PI0050?
      Answer :Both " 0000 "and" FFFF " are "initiative code".
 
6.How is the "initiative code" exactly identified on the parallel-port PC Analyzer L50?
      Answer :Both " 0000 "and" FFFF " are "initiative code".
 
7 .How is the "initiative code" exactly identified on the PC Analyzer M04?
      Answer :Both " 0000 "and" FFFF " are "initiative code".
 
8.If the code is not included in the manual, what can I do?          
      Answer :As the main board manufacturer defines the codes, Some codes haven't been defined. So If you want to know the meaning of the code that is not in the manual. you can get in touch with your main board manufacturer and make a consultion.
 
9.The meaning of the code 00and FF?                                
      Answer :The meaning of the code 00 is as same as the code FF.There are three conditons in the meaning of code 00 or FF as follows:
      Ⅰ.If there is a series of codes that don't include "00" and "FF" varying and it stops at the code of "FF" or "00" in the end, the POST is normal. The hardware system is ok!
      Ⅱ. If It indicates the code of “00” and the code dose not vary, the main board hasn't run . Please check the CPU, the CPU jumper, The CPU configuration, the power and the battery of the main board.
      Ⅲ . If you set that it dose not point the error out in the CMOS setup and there is common trouble with the computer. There is still a series of codes that don't include “00” and "FF" varying and it stops at the code of "00"in theend. At this time you can set that it can point all the error out in the CMOS setup. If there is common trouble with the computer, it can stop and indicate the error code. You can correct it by the error code according to the code table.
 
10.Is code 26 "trouble code" or "OK" code?                          
      Answer :When the" trouble code" that PC Analyzer displayed is 26, It is pivotal for you see whether there is display on the screen. If there is, the code 26 is "OK" code. Even though there is some trouble, it is nonfatal (for example , Setup of BIOS is wrong.)and dosen' taffect the display. the non-fatal "trouble code " wouldn't be sent to the PC Analyzer. You can read the   words about the trouble on the screen of monitor. directly and solve the non-fatal trouble according to it; Else,the code 26 is" trouble code" its meaning is : test the  exception situation of protected mode. Please check the memory of CPU and main board.
 
11.Statement of signals LEDs group for PI0049 series and PI005OA series that own PCI bus and ISA bus.
      Answer :When PC Analyzers such as PI0049 series and PI005OA series is inserted in PCI slot, The power indicators are 12V,-12V,3V3 and 5V;The singals indicators are IRDY,FRAME, CLK,RST and RUN.There is no indicator for -5V,BIOS and OSC.
      When PC Analyzers such as PI0049 series and PI005OA series is inserted in PCI slot, The power indicators are 12V,-12V,3V3 and 5V;The singals indicators are IRDY,FRAME, CLK,RST and RUN.There is no indicator for -5V,BIOS and OSC.
 
12.Statement of FRAME LED and BIOS LED.                               
      Answer :When PC Analyzer is inserted in PCI slot, If FRAME LED is on, It indicates that there is cycle frame signal of PCI slot or MiniPCI slot at the moment; If FRAME LED is off, It indicates that there is no cycle frame signal of PCI slot or MiniPCI slot at the moment. If FRAME LED sparkles, It indicates that duration of cycle frame signal is short. Sometimes there is so short duration of cycle frame signal that you cannot feel the FRAME LED have been on by naked eyes. the same kind, if sometimes the cycle frame signal have vanished for a short time, the time is so short that you cannot feel the FRAME LED have been on by naked eyes.
      When PI0050A-S or PI0050A-SD is inserted in ISA slot, If BIOS LED is on, It indicates that BIOS is not being read from at the moment; If BIOS LED is off, It indicates BIOS is being read from at the moment. If BIOS LED sparkles, It indicates the time for which BIOS has been being read is short. Sometimes there are so short time that you cannot feel the BIOS LED have been on by naked eyes. If sometimes BIOS has not been being read for a short time, the time is so short that you cannot feel the BIOS LED have been off by naked eyes.
