Check out www.bb-elec.com. We use many of their model 485LP9TB at $59.95/ea. Regards, Wayne Dowdle D #### Duncan E. Walters You have two different voltages for RS-485 and RS-232C. You will need to utilize a converter. Check out Black Box Company for their products. It's always a good start for communications products. Good Luck Duncan E. Walters [email protected] W #### wk i think you should take an interface, i.e. spectra I7520 (www.spectra.de) M #### murali mohan RS485 is based differential signals where as RS232 is not. Hence You cannot directly connect the two with just a cable. You need a converter. These converters are available in the market of the shelf. It is a simple device with one or two ICs. Can even make one your self HTH Thanks G #### Gannel Leonid You might use standard converter ADAM-4520 from Advantech, Regards, Leonid Gannel R&D Servo Control Engineer NUR Macroprinters Ltd.

Grayhill (available from Newark in the US and Canada) has their model 72-CNV-4 and 72-CNV-5 for about$ 110.00.

I actually use one I picked up from a local computer outlet for about \$ 45.00.

It is more than just a cable.

You can learn about it in the Technical Documents on www.blackbox.com

>Depending on your application, Black Box tends to range in the upper price range. I suggest you look at B&B Electronics for a variety of Communications Interface devices.
