The is surprisingly clear and well laid-out, and explains the full pinout in more detail (including optional connection through to thermal receipt printers etc.), though I'll be using just the minimum ...

On the Arduino, dedicated digital pins D0 (Rx) and D1 (Tx) are used for embedded serial communication applications. Using pins D0 and D1 other than for data communications will cause an electrical ...

1. Send command to the device through RS-232. 2. Get responses from the device through RS-232. 3. Send the device responses to the human-machine interface (HMI) through Serial1. 4. Arduino can monitor ...
