Wiring an Arduino nano to a RS232-C connector for serial communication
I am trying to wire an Arduino nano to a RS232-C connector so I can send and receive files from a TRS80 Model 100 computer. I am unsure how to wire the connector properly however. I know that the Arduino nano a RX and TX pin but I don't know if that will work with the other device listing RXR and TXR on the pinout. I also don't know what pins to wire the connector up to. Can someone help me draw up a wiring diagram for this?
