NULL MODEM CABLE PINOUT DB9 TO RJ45

A null-modem cable is essentially aserial cross-over cable where one end's TX goes to the other end's RX. If you use identical DB9-RJ45 you're getting TX-TX and RX-RX. If they're the snap apart type, you may be able to move the wires inside to the appropriate pins to make one side the cross-over (then mark it as such).

Apr 04, 2019Null modem, also called crossover, is a term associated with serial (RS-232) cables. A standard serial cable, also called an AT cable, has the wires inside the cable running straight through. Take a DB9 cable as an example. Pin 1 on one end of the cable would be connected to Pin 1 on the other end. Then Pin 2 to 2, 3 to 3, and so on.
