The NET485 Enhanced is the newest version of the NET485 with enhanced Firmware. This device is an economical Serial-to-Ethernet adapter with the features of a high-performance device server.

Enhancement Areas

  • Additional DNS support
  • Multiple TCP connections
  • Email authentication and serial triggers
  • Idle gap time
  • UDP datagram


The NET485 RS485 serial to Ethernet adapter allows you to connect either RS422 or RS485 transceivers in your host device to the local network. This connection makes the device network-enabled and eliminates the limitations generally imposed by cable length. Now, the user can communicate with the serial device from anywhere on the network.

The NET485 can be installed up to 4,000 feet away from the host device. Additionally, two NET485 adapters can establish a TCP/IP link for "serial tunneling" data over the local network or the internet as a virtual cable replacement.

Using the RS485 two-wire half-duplex mode, the NET485 serial interface can connect to several devices within a multi-drop network. A built-in web server allows for customized web pages. Serial cable wiring is attached using the labelled screw terminals on the removable terminal block. Power is by an external DC voltage that is connected to the terminal block.

Use the NET485 anywhere a device server is used. With a wide temperature range, the NET485 can be used in commercial and industrial applications.
