Hi!

I made the pcb and found some problems on it.
Here is the schematic and the pcb what I found on the net.
As I figured out the schematic didn't meet the pcb. After I made the pcb and put all together I figured out does the programmer does not recognized by the software from Elnec. I found the problem with the diode on the LPT pin 2 and 15 was wrong configured. After the correction it was fine. But the programmer still not programming the eprom.
Does somebody have some experience with this type of schematic?
I need help to solve the problem whit this please.

Do not know about the specific schematic or unit, but I do know there has been some schematics floating on the net that is more than likely not the original. The only thing I can suggest is to compare yours with the copy residing at Elektrotanya.com (if it is not where you got it).

I have been using a verion of LABPROG at work for several years and while discontinued, it has been perfect.

As far as the LABPROG tester goes, to the best of my knowledge, when you start the computer and invoke the PGWARB software, there is a brief communication with the computer where it will recognize the tester along with the serial number and then it is ready for operation.---whether it would be the same with seeprog, I am not sure?

Hi!
Sorry because I'm late.
I do not know about the schematic on elektrotanya.com. I cant register because I have to get an invitation or something like that.

I will check for LabProg.

Thank you.

I think you may have misunderstood what I said, The Labprog I did not build. It was already made by Elenec.

Do not need any invitation for Elektrotanya as long as you limit your download to two

Look in the middle of the page and wait for get manual

No no, I know you did not build your LabProg.
I appreciate it for your help and will check the schematic.

Thank you very much.

Are you sure the schematic you have is correct? You can run a simulation of the schematic in any free circuit designing software and test if it works or not. You can even do the troubleshooting first in the software before transferring it to the PCB. Then is every works fine, trace the PCB design you have and check if it match the schematics before continuing the project.
