Overview
The NePort™-485 is the most compact, integrated solution available to web-enable any device with an RS-422
or RS-485 serial interface. By simply adding NePort-485 to a product design, device manufacturers cut their
design cycle by as much as 80% and are able to offer Ethernet connectivity in record time.
The NePort-485 is configurable for either RS-422 4¬wire or RS-485 2-wire communication. It supports multi-drop
RS-485 networks by providing a logic level serial interface designed to connect directly to an RS¬485 transceiver
chip. In the RS-485 2- wire mode, one of the PIO pins supplies the necessary transmit enable signal.
Multi-threads operation system and protocols Support
· With multi-threads real time operation system embedded in a 32bits RISC
· ARP, UDP, TCP, ICMP, Telnet, TFTP, AutoIP, DHCP, HTTP, for network communications.
· TCP, UDP, and Telnet for connections to the serial port.
· TFTP for firmware updates.(E version)
· IP for addressing, routing, and data block handling over the network.
· User Datagram Protocol (UDP) for typical datagram applications in which devices interact with other devices
without maintaining a point-to-point connection.
· SMTP: E-mail alerts
