2. Fully automatic & no manual set-up needed (eliminate all jumpers & DIP-switch) 

It has outstanding performance which supports the devices that other similar products are not capable of supporting: such as 25LF SPI series, PSOP44,TSOP48, 25VF SPI series, Altera Xilinx CPLD JTAG, PLCC84,SST39VF3201, TE28F102, 27C1024, 27C1028,HD6475,29F800, 29LV800, 29F032... 

Key & Unique Features 

1. Complete new professional design with own robust enclosure and 40pin ZIF socket 

• Neat rebust enclosure is designed to suit the portable and field convenient applications
• 40 pin of the ZIF socket supports more chips without adapter
• First and only Willem programmer with 40pin ZIF socket, other models use 32pin ZIF

• Uses only one USB cable to connect with PC/Laptop USB port for both data transfer and power supply. The bulky DB25 data cable is eliminated & no longer needed for data transfer between PC and programmer board
• It is True/Real USB data transmission protocol (USB-USB), Not via Fake/Pseudo-USB data communication.
• Fake/Pseudo USB data transfer needs the middle serial or parallel port conversion: USB-Serial-USB conversion or LPT-USB conversion, this limits the programming speed significantly.
• GQ-4X features the same revolutionary data interface as GQ-3X, the True USB data transmission with PC/Laptop.

5. Exponentially speed increase up to 20 times faster 

• Connects PC via high-speed USB link, provides the fastest possible data transfer rates for programming/reading data from target IC's.
• It is capable of being up to 20 times faster than other existing printer port Willem (parrellel LPT Willems: PCB6.xx,PCB5.0C,PCB4.5C) programmers on reading & verification a high density flash device, this significantly saves your time and increases work efficiency as well as facilitates small scale production
• Assembly language written programming algorithms run fast and reliable. Not affected by the PC speed changes and Windows 0/S variations.

6. Dual power supply capability: USB port & AC/DC and automatic voltage control 

• Vcc supported among: 3.6V, 5V, 5.5V, 6.5V
• On-Board MCU for stable performance & automatic/accurate voltage control
• Works best among other programmers for EPROMs

7. The GQUSB software is especially developed for True USB Willem programmers GQ-4X,GQ-3X, GQ-2X. 

• Free Life-time software download/upgrade, please click here for software revision history
• Updates software and device algorithm regularly
• Free IC device updates via web
• Supports O/S: Win98SE, Me, XP, NT, 2000 &  WinXP 64bit, Vista 32bit, Vista 64bit Windows7 32bit 64bit , Windows 8, Windows 10 (English)
  
• Advanced software engineered to provide most user-friendly interface & simplest and easiest-to-use Willem programmer version to save time and comfort to use
• Multi-language support, such as: English, German, Spanish, Chinese,French,Czech, Portuguese
• Programming history memory function on-board
• Supports most popular ECU, Satellite, xBox, Wii, BIOS, EPROM chips: SST39VF3201, TE28F102, 27C1024, 29F800, 29LV800...
• Supports the chips that LPT Willem are not capable of supporting, like 24RF08,28F102,87C257 and more
• Supports TSOP48,PSOP44,16bit EPROM chips that 40 pin TOP,EasyPro,Wellon are not capable of supporting
• Supports 25LF SPI series, 25VF SPI series, Altera Xilinx CPLD JTAG, PLCC84,29F032...
• Allows end users add in their own chips/devices easily (editing .txt file)

8. Working with the adapters further expands the supported devices list
