The file xf-adesk20_v2.exe is a legacy patching or key-generation utility. Software cracks of this nature are heavily circulated on peer-to-peer (P2P) networks, untrusted forums, and shady file-sharing blogs.

Hardware Installation & Configuration

Installation Steps
  

  • Check the parallel printer port setting in the bios, it should be EPP or Normal.
  • Check there are any active resident programs that use the printer port, such as TWAIN drivers. You may have to remove it.
  • Connect one end of the 25 pin SubD parallel cable  to PC printer port
  • Connect the other end  of parallel cable to 25 Pins port of the programmer
  • Connect USB power cable or AC adaptor (Note: if you are working on the EPROM programming. You may need use a AC adaptor, so that you can get Vcc 5.6V and 6.2V when doing programming)
  • The yellow power normal indicator of the programmer should light up, then the programmer power supply is normal.
  • Run the software
  • Select devices type
  • Click the Willem in toolbar to change to PCB3
  • Set the DIP switch based on the displayed pattern.

          (Note: the LPT port of PC MUST set to ECP or ECP+EPP during BIOS setup. To enter the BIOS setting mode, you need press "Del" key or "F1" key during the computer selftest, which is the moment of computer just power up.)

 

Software Version To Use

The software can be download from download.mcumall.com  

There are board hardware selection jumper on the board. When set the jumper to PCB3B, then user have to use 0.97ja and before version software.

If the board selection set to PCB3.5, PCB5.0, PCB5.5C, then the software 0.98D6 should be used.

 

          The software interface:

Hardware Check

After start the program, click test hardwar under Help menu. If the connection and power supply is normal, then appears: "Hardware present"   Otherwise check if the programmer connects well with PC, or power supply is normal.

 

Jumper Configuration

 

PCB3.5/PCB4E

(Two PLCC32 adapter is not applied on the PCB4E)

PCB5.0

xfadesk20v2exe exclusive

PCB5.5C

xfadesk20v2exe exclusive

Note: the Vcc setting jumper only has effect when you are using AC adaptor as power source. For the USB power only 5V Vcc is available.

For the PCB5.5C, set DIP steps:

1. press DIP Set button twice to check current DIP bit position. Then set it again for ON or OFF.

2. press DIP Bit shift button to shift the DIP bit position to where need to set. And then press DIP Set button twice to check current DIP bit position. Then set it again for ON or OFF.

3. Repeat those steps till all DIP bit ae set  same as software indicated.

For PCB5.5C voltage and Special chip selection:

1. Put back the safety jumper.

2. Press the voltage button and hold for 1 second, the voltage LED should move to next. Repeat till desired voltage LED light up.

3. Press the chip selection button and hold for 1 second, the chip LED should move to next. Repeat till desired LED light up.

4. Remove the safety jumper to lock the selected voltage and chip selection

DIP Switch (PCB3.5, PCB5.0)
