The serial port COM4 on the TPC-1070 is adjustable. It can be set to RS- 232, RS-422 or RS-485. This port is designed with auto data flow control capability. In other word, the TPC-1070 can automatically detect the data flow direction at this port when the two wired RS-485 communication is activated.
