The NET232+ is the next generation of advanced serial device servers from Grid Connect. The new “PLUS” provides a simple solution enabling RS232 serial devices to connect to the network via Ethernet and TCP/IP (RJ45). Use the NET232+ to extend the life and utility of existing RS232 serial devices.

Fully Featured Device Server

The NET232+ is a fully featured device server supporting multiple TCP connections (up to 4 TCP or a mixture of TCP and UDP), DNS, email serial triggers, email authentication, and 256-bit AES encryption. Serial data rates up to 921K and auto-sensing 10/100Mbps Ethernet are supported.

Included Features

  • an industrial grade temperature range
  • detailed LED status indicators
  • factory reset push button

Refer to the NET232+/NET232 Comparison Sheet for a detailed list of the NET232+ enhancements

The NET232+ is simple to configure using the provided installation software and web page. Just connect the adapter to a serial device and to the local Ethernet network and run the free software to find and set up the device. Use the NET232+ in pairs to “tunnel” serial data over the internet, or as a single device connected to a serial device on one-end and to a “virtual COM port” on a PC on the other end. This is accomplished using the free virtual COM port software.

Serial Tunneling Configuration

Direct TCPIP Configuration

 The NET232+ is backward compatible with the NET232.
