COM2: RS-422/485
The COM2 serial ports on the TPC series systems can be adjusted via the BIOS
menu and set to RS-422 or RS-485 mode. This port is designed with automatic data
flow control capabilities. In other words, the TPC series systems can automatically
detect the data flow direction at this port when two-wire RS-485 communication is
activated.
