You will need a 9 - 25 pin serial adapter form any supplier (like Radio Shack) and a Siemens part 6es5-734-1bd20 seial (25pin female) to current loop cable. It comes with the 15 pin male, needed for their PLC's.

You can use a B&B 232PCLR and make you own cables, it is a lot more work and requires an external power supply. I do have a drawing of that.

I do not think you want to try a home made cable.

You have to have the pc-converter: P\N 6ES5 734-1BD20.

Check the downloads section on www.plcman.co.uk . There's a drawing to make your own cable for under $50 as I already have mentioned in this post .

Kind regards,
