Gateway Connection to AS/400 and AS/36

ES/ServerES/Server - Hardware/Software Gateway for
Windows? Connectivity to IBM? S/3X or AS/400?

PLEASE NOTE:  ES/Server is a discontinued product and is no longer available. Please Click Here and you will be taken to the page for
the TwiNetTC Gateway for IP-to-Twinax Connectivity


ES/Server from NLynx is a low-cost hardware/software gateway for IBM AS/400, System/36?, and Advanced Series/36? users, which allows sharing of a single Twinax connection among seven users on either a Token Ring or Ethernet LAN. Bundled with NLynx’s 32-bit Emerald Series Software for Windows and Windows NT?, ES/Server provides powerful, proven 5250 emulation for both Server and Client PCs.

With multiple ES/Server adapter cards, you can control multiple AS/400s from a single network mode.  Our Multiple System Console Program (MSCP) configuration can help you with this burdensome task.

  • Flexible Twinax connection means increased productivity. The ES/Server solution uses a Twinax connection to the host IBM midrange system through a gateway server PC, which means that it can support the IBM AS/400, System/36 and Advanced Series/36. Since the server provides a single point of contact to the midrange host, there is less configuration and operating overhead, providing better overall host performance.

  • Simple, intuitive installation and configuration. On the PC side, a single protocol can be used for both LAN and host PCs, and since ES/Server is a native Twinax gateway, it does not require the overhead and configuration complexities of an APPC router. ES/Server supports IPX, TCP/IP, and NetBEUI between the Client PC and Gateway, saving the user from having to configure multiple protocol stacks. And the Emerald Series Client software installs quickly and easily, using industry-standard LAN interfaces.

  • Supports most common protocols. ES/Server supports the most common protocols, provided with Windows 95/98 and Windows NT support in a single solution.

  • Multilanguage support. Localized product for English, French, Italian, German, and Spanish.

  • Hotspots identify host menu items. Host menu items and function keys can be assigned colors. Employ this aesthetic and intuitive approach to locate them quickly and easily, with the simple point-and-click of a mouse button.

  • Keystroke memory and playback (macros). Predefine keystrokes for automated sign-on, repetitive data entry, or unattended operation. Store as many as 2,048 keystrokes in up to 24 keyboard macros.

  • ETU? file transfer support. ETU, an industry standard from NLynx Systems, allows direct file transfer between the PC and System/36, Advanced Series/36, or AS/400.
