Hello, and hi to all. I'm new to this any any help would be grate full ! might be a easy answer to my question but I am having trouble with the Hex thing. I hit the write button and get following message: Device write failed at address: 0x000000, Buffer=0xa0 Device=0xff Device write error. trying to burn a 2732a 21v, I'm using a external 12vdc 300ma ....what do you enter in the file offset(HEX) and the Device Offset(hex) boxes? Thanks for your time and input......Mark...:)

Please check all DIP setting are correctly set and also use a multimeter to confirm those DIP bit switch are contact well when it is on.
Thanks for the info. Seems that might be the problem, Burned one with no problem then had same problem again. also need to check the cable its self, use a another one.? |

What the brand of your 2732A EPROM? Sicne those EPROMs may have specific condition to program. So, always use the exact match device type to program it. Include the brand name.
Also, try both with and without external power adapter see if it makes any difference. This will give some clue for the failer.
O.k, Tried all GQ-2 listed manufactures for the 2732 chips, all diffrent voltages 12 21 ect. ,with external power and without, known good bin file. I even read a chip ,saved file,ereased chip and would not write same file back to chip. message when verify: (Device verify failed at address: 0x000000, device read 0xff, buffer is 0xa0)

Thanks for your input. I'm using the 2732a Eprom that I understand they are 21v.eproms. I have removed three or four from Automobile ECM'S removed Data tag covering chip and erased using UV light. Selected device type ,eprom 2732a 21v ,and after blank check them.....good, open new bin file to buffer and when write I still having message in above post. |

You do not need enter anything in the offset field.
What exact part number you are programming?
Make sure your EPROM is a good one. From my experience there are lot of old EPROMs are damaged(no longer can be programmed) but user do not know. |
