I recently picked up a used Digi Etherlite 32 serial concentrator from ebay. It didn't come with cables, it took me a few tries with conflicting documentation on the internet before I found a pinout that would work to connect it to my Cisco lab. Below is the pinout I am using currently. Note that the Cisco has two ground pins and the Etherlite has only one, so you could potentially make a better cable by bonding the two. I was lazy, I just ignored the other one and it seems to work fine. I cut off one end of my pre-existing rollover cables, hence the funky coloring rather than cat5 standard. If you're making both ends just follow the arrows, the twisted pairs aren't really going to matter.

... should do the trick. I don't really recommend this though, since if you only take a look at one side of the cable you might think its a normal ethernet cable. Its an easier cable to make though, rollover cables are extremely obnoxious to re-punch.
