Hi guys,
bought my new usb epromer and want brun the 27C322 like with my old lpt
version.
Connect via USB native 5v port and also tried a DC Adapter with 9-12V.
Each try result in following issue
1. 27c322 are blank
2. If iam pressing to Write, i got on 0% a write error
Try 10 x 27C322 eproms and got
"Write failed, Address=0x000001, Buffer=0x61 Device=0x63"
3. Tried my old 27C322 16 Bit adapter. Connect A19,A20 and A21 to adress connector on usb willem and check for empty eprom. If i start the write process the state goes to 25% and i got a errormessage.
Check all contacts on ADP 054 for solder problems and resolder all point.
X-Test epromer with other usb cable and other pc system -> same issue.
My OS is Windows 7 ultimate but iam realy sure that this is not a OS problem or driverissue.
Change J5 - to V3 and V4. What does this mean Epromer version GQ3 or GQ4?!
J1 is set to 2/3.
Could it be that the eprom is not set to the correct location on zif?!
Hey made a image.

Data are note correct ;/
Thanks in advance

Sorry. It should be "This chip does not need external power adapter."
If your old adapter works on GQ-4X, then it must be the adapter problem.

It seems the chip has poor pin contacting.
1. Try to push the chip left/right on the adapter after locked.
2. Try to push the adapter left/right on the programmer after locked.
This chip does not need external adapter.
The 25% error is the address connection problem.
The willem doesn't recognized 10 eproms in a row. I dont think is is a pinproblem...
You have written "This chip does not need external adapter."
Are you shure? The 27C322 doesnt need the ADP-054 adapter?!
Like already posted: My old adapter with adressextenstion works fine.
Thanks
