[PLC] programming cable for FESTO controller

Hi!
I'm a student of Silesian University of Technology (in Gliwice, Poland), and I have a task - I must repair a broken program in FESTO controllers.
It's a simple thing, but I have a one difficult problem... I don't have a cable to connect controllers with computer...
I found in Internet that I need a cable appointed as: PS1-SM14-RS232 (in FESTO catalogue it has a number: 188 935). FESTO company wants to sold it for my - but the price it's to high. I need this cable only for download the program to the computer, and upload it back. So the price 250 PLN (more than 60 euro) it's to much for me.
So - I have a question - can anybody help me with me problem? Is here anybody who meet this controllers, and who can help me with make this cable? In Internet I found only this information:
http://www.beck-ipc.com/bc/products/ps1/category/view/index.asp?cat=8&prod 141&sp=en
but it's too little for me. With this information I couldn't make this cable.
I believe that somebody can help with my problem, and I will finish my task ;-)
Best regards,
Michael

Without the pinout, anything else is useless. The picture shows a 9 pin D connector eventually terminating in what looks like the equivalent of an RJ-45 connector(US). That is 8 wires that could go anywhere.

the one I have is a 6 pin RJ-45? connector wired straight through to another RJ-45? connector, this is the same as the screen to PLC cable, then it plugs into an RJ-45? to serial adaptor and what appears to be a standard serial cable

I clicked on the "Datasheets" link on that page and the complete pinout for both parts of the cable is shown. You will still need to build an RS-232 to TTL converter circuit. At first glance, it looks like four channels, two in and two out. Maxim semiconductor makes a large assortment of IC's for this purpose, for example: http://www.maxim-ic.com/quick_view2.cfm/qv_pk/1047/ln / The data sheets give example circuits. More data on RS-232 is available here http://www.camiresearch.com/Data_Com_Basics/RS232_standard.html

Hi!
Thanks for your help ;)) I've just found a more interesting diagram for this cable, and now I'll be able to make them ;))
Once again - thanks you :)
Best regards, Michal

It should be simple enough, and cheap enough to build your own. Both connectors easily obtained. For wiring, see http://www.exorint.net/docs/0/F9C6FD92BB4DF3FDC1256FC600427DE8 /$File/CA233-0.pdf
