1. RS-232 communication cable (through) has a standard length for selection, and the communication cable has a shielding layer
2. RS-232 uses only 2, 3 and 5 pins for communication, which are respectively receiving line RXD, sending line TXD and signal ground line GND"

Ethernet port is LSE edition. LS and EIA with no ethernet port.
