Question:
I have the serial to Ethernet converter USR-TCP232-306 and do not know how to select the RS485 or the RS422 mode on the device.
There is no choice on the Web setup pages.
Answer:
USR-TCP232-306 is a single-port serial to Ethernet converter. Only one serial port can be used at a time. So the type of serial port used depends on your wiring.
If the wiring is correct, the serial to Ethernet converter USR-TCP232-306 will automatically adapt itself, no configuration is required on the web page.
