[Repeater-Builder] DR-135 and DR-435 into a simple crossband rptr

Hello, I am wanting to make a crossband repeater out of a DR-135T and a DR-435T Alinco radio. How does someone do this? Can I just hook up a straight DB-9 to DB-9 serial cable from one to the other and it will work? Or do I need to build a cable with different wiring? Thanks 73, Brad KD5AR
