  • Software-selectable interface prevents tampering in the field.


  • Easy to manage through any Web browser or Telnet.™
  • Secured with 128-, 192- and 256-bit AES, 3DES, Blowfish, and CAST128, plus ARCFOUR or ARCTWO data encryption across the LAN via SSH and SSL.
  • Power over Ethernet (PoE) models are IEEE802.3af compliant.
  • Include COMredirect software to provide true remote serial ports over an Ethernet LAN.
  • Feature a 66-MHz, 87-MIPS processor.
  • Built-in surge protection on all interfaces.
  • Can be DIN rail mounted with the DIN Rail Mounting Kit (see Secure Device Server Accessories).

  • Secure Device Servers enable you to use your Ethernet network to securely access remote RS-232/422/485 ports on serial equipment such as industrial equipment or security devices.

    Secure serial connectivity
    The servers protect sensitive data from serial devices such as credit card readers through encryption with Secure Shell (SSH) and Secure Sockets Layer (SSL). The device servers also support all major encryption ciphers such as AES, 3DES, RC4, RC2, and CAST128. User authentication through RADIUS, TACACS+, LDAP, Kerberos, NIS, and RSA Security's SecurID tokens ensures that only authorized users can access the system. Secure Device 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 in encrypted or clear text modes. The device servers also support SNMP for integration into managed networks.

    Secure Device Servers are easy to manage through any Web browser or Telnet. They include Device Manager software to provide central control of multiple terminal servers, so you get maximum uptime for your remote equipment.

    Powered by Ethernet
    The Power over Ethernet (PoE) models of the device server operate as a Powered Device (PD), fully compliant with IEEE 802.3af PoE specifications. It features inrush current protection guard against input current surges that may occur during power up.

    Dialup, too, if you need it
    The LES5016A model features an integrated V.92/V.90 modem with support for PPP dial-in connections.
