The GDI1000 TCP/IP converter is designed to make your serial devices Internet ready instantly. The GDI1000 TCP/IP converter makes the ideal choice for connecting your RS-232 or RS-422/485 serial devices—such as PLCs, meters, and sensors—to an IP-based Ethernet LAN, making it possible for your software to access serial devices anywhere and anytime over a local LAN or the Internet.
These converters ensure the compatibility of network software that uses a standard network API (Winsock or BSD Sockets) by providing TCP Server Mode, TCP Client Mode, and UDP Mode. The included Virtual COM driver, software that creates a virtual COM port can be set up to work over a TCP/IP network in no time. This  feature preserves your software and hardware investment and lets you enjoy the benefits of networking your serial devices instantly.
The GDI converters support manual configuration via a convenient web browser console.  Protocols supported include: TCP, IP, UDP, HTTP, DHCP, ICMP, and ARP.


  • Data Conversion between RS-232/422/485 and Ethernet
    Convert serial device (RS-232, RS-422, RS-485) data/signal into the TCP/IP package data/signal and send them out with the Ethernet Data Stream or convert the TCP/IP package data/signal into serial device data/signal.
  • Dynamic IP Configuration
    Supports DHCP client mode, simplifying network address configuration and management.
  • Dual LAN Speed
    Support 10/100 Mbps Ethernet, auto-detected.
  • Server / Client Dual Modes
    The 8051 Series can be configured as network server or network client. In the client mode, it can be installed in network which is protected by NAT router or firewall, without the need of a real IP address.
  • Web-based Setup
    Parameters setup are based on HTTP protocol by using standard browsers (IE and Firefox). No special software is required.
  • Built-in Security Control
    Protected by setup password to prevent intruders.
  • Firmware Remote Update
    Firmware can be updated directly via Ethernet network to keep up with latest network standards.



Real COM Drivers for Existing Software
Thanks to GDI's Real COM  drivers, software that works with COM  ports can now work on a TCP/IP network in no time. This excellent feature preserves your software investment and lets you enjoy the benefits of networking your serial devices instantly.

Easy installation and configuration
GDI1000 serial device server supports automatic IP configuration protocols (DHCP) and manual configuration through the web console. This ensures a quick and effective installation.  Firmware is updateable over the LAN.
