Below is a picture of two cables. Both are 9W to 9W serial data leads and both are wired one to one.

One of them came from CPC and cost around £3. One was purchased from a manufacturer of high voltage DC power supplies and is used to link two of their supplies together - no details were given at the time of purchase but we were led to believe it's a very special lead. And the cost of this one? I hope you're sitting down - £230!!!!!
