HELP! Dongle not found on my computer
I just bought a DCT4 Calc, but my computer won't detect my LPT-port dongle. I've read a little bit about low power being a possible reason. Someone help me out, please! I've tried running programs to increase PC workload, but it didn't help.

same prob here but it doesnt work even with external power from usb

I tried it on my friend's computer and it works, he has XP, but I don't think that's the reason because I tried another XP computer that didn't find the dongle like my windows 98 computer.

So now he's my best friend.

solder a wire with 5v usb power to pin 20 on the amtel inside the plastic case.

Then it should work

If you are not sure what you are doing - I am not responsible

DESKEY drivers
Did you install DESKEY drivers???:confused:
If not try to find on net archive
dk2wn32.exe and install it, after that try your calculator.

Guys, this is how I fixed the problem:

1) get yourself a USB cable
2) Cut off the square end of USB cable and strip back to the wires
3) Find the RED wire and cut down others (not needed)
4) Remove outer shell/casing from dongle
5) Take RED wire from USB cable and solder it to pin 20
6) Replace casing - take care in doing this
7) I then used a hot glue gun to seal area where USB cable coming out.
8) Plug dongle into LPT port
9) Plug USB into USB port on pc
10) EnJoY the use of DCT4 calculator!!

To help you find pin 20, I have a pdf document with pin out.

Please view it here:

Yeldar :D

Please note; I take no responsibilty or accept no liability for any damages to your dongles or pc while attempting this modification. It worked 100% for me. If in any doubt, seek further advice.

did that still not working lol ****ing dongle

yeldar 03-12-2003 21:44

Perhaps dongle faulty???

I have spent hours searching and checking out possible problems and apart from setting bios, this is most common modification to make it work!

Yeldar ;)

bcool 03-12-2003 21:52

Nope. Dongle's working fine in other pc's

yeldar 03-12-2003 22:08

have you checked bios settings??

This can cause same fault

kino2000 03-12-2003 22:11

x Gnosis:

Can you read the ATMEL inside your dongle???

This way you can help lot of people to make their own dongles...

Thanks in advance.

bcool 03-12-2003 22:52

yeah man.. tested with all possible bios settings...

the stupid thing is that all other dongles work 100% in this pc..
