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

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

You might use standard converter ADAM-4520 from Advantech,

A simple cable will not allow you to convert from RS-232 to RS-485, since the respective voltage and hardware standards are quite different.

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.

Best regards, Bob
