din5 to mini din 6 adapter

[Sebastian]

Hi, I have a little problem with a barcode scanner, it has a rs-485 to din 5 adapter cable to plug it in to the keyboard input on a pc, the problem is that I want to use it on a new atx pc that has a mini din6 keyboard input, I tried with an adapter but it dind't work, the scanners turned on, it scanned one time but the data never reached to the pc and it hangs.
It's there any way to make an adapter from the rs-485 interface to mini din6 directly?

Sorry, about my english.
