- To connect an Arduino to an RS232 device, you can follow these steps123:
- Hook the 'tx in' pin to an Arduino digital output pin.
- Hook the 'Tx Out' pin to the DE9 pin that you want to drive.
- Use the USART on digital pins 0 and 1, and be unable to talk to the computer while you're using it to communicate with your RS-232 device.
- Use an Arduino board with more UARTs or USARTs on it, such as the Mega.
- The 9-pin DB9 cables are used to connect with the RS232 standard. Since the connection is between the DTE and DCE, the pins are assigned a 1:1 order. That means the Nth pin of DTE should be connected to the Nth pin of DCE2.
