Overview
2.1.
Brief Introduction
USR-N540 is used to transmit data transparently between TCP/UDP data packet and RS232/RS485/RS422 interface. It
carries ARM processor, low power, fast speed, high stability and four serial port can work as RS232 or RS485 or RS422
serial interface which comfort to industrial standard.
