  • Built-in surge protection on all interfaces.
  • Clear LEDs for easy troubleshooting.
  • 66-MHz, 87-MIPS processor.
  • Optional DIN rail mounting with the DIN Rail Mounting Kit (see our Secure Device Server Accessories).

  • Make the connection to serial devices such as sensors and time clocks—even industrial devices such as milling machines and conveyor belts. These simple 1-Port 10/100 Terminal Servers make the connection easily, yet offer the sophistication that make them indispensible in large, managed installations.

    Manage them through any Web browser. 10/100 Terminal Servers support Next Generation IP (IPv6), making them compatible with networks that have upgraded to this new IP standard. Plus the included COMredirect software provides fixed TTY or COM ports so server-based applications can communicate accurately with serial devices. The terminal servers also support SNMP for integration into managed networks.

    These compact terminal servers are housed in a solid steel enclosure, which can be used on the desktop or wallmounted. Plus, for industrial applications, they're DIN-rail mountable with the DIN Rail Mounting Kit (see Secure Device Server Accessories).
