To make a cable for the SERT, to replace the original short cable, I use 2 adapters and a standard Cat5 network cable. Both should be available at Radio Shack or a local computer store.
The adapters are easy to make. You want 1) RJ-45 to Male DB-9 serial connector and you want 1) RJ-45 to Female DB-9 serial connector. They come in a kit form, an example is in the first picture.
Next you have to plug the wires into the DB-9 connector. On the back of the connector there are pin numbers. Each wire is a different color. Take both adapters and plug the same color wires into the same number hole on each DB-9. Example, take the blue wire and plug it into pin 1 on the connector for both adapters. Then yellow in pin 2 on each connector. Do this for all the pins. There are only 8 colored wired and 9 pin holes.
DON'T USE PIN 9.
This is what they look like when completed. Note that pin 9 is missing.
After making these adapters you can the purchase any length Cat5 network cable and plug each end into each RJ-45 on the adapters. I would keep the cable length to less than 100 ft. I use a 60 foot cable without problems.
