Went down to the local electronics store and bought a ribbon cable and an RJ-45F to DB9F adapter.
But now that I'm looking at documentation, I'm confused. As best I can tell, BOTH wires 4 and 5 from the ribbon cable have to go to pin 5 on the DB9. However, the leads are already clamped firmly on the wires. There is no way I can possibly cut the lead off, splice the wires, and then get the lead back on.
I just want to make sure I'm reading this correctly. Do I really need to splice wires 4 and 5 to pin 5 on the DB9?
