產品概觀 :

ZiPCOM’s Single-Port X.25 Synchronous PCI Card (ALEX.25 PCI Card), is truly a perfect solution for complex and versatil e high-performance synchronous communication applications for X.25 protocol. You simply need to make use of ZiPCOM's Alex API functions to develop your own applications to meet your business requires.

An onboard CPU, combined with memory, effectively reduces the burden of the server CPU, bringing overall performance up to 64Kbps on port.

The Alex library provides complete HDLC/SDLC/LAP-B(X.25 layer 2) data communications control conforming to CCITT, ITU, including frame formatting, bit stuffing, and error detection. The library also provides complete X.25 protocol (layer 3)communications control conforming to CCITT, ITU, including package formatting, control, configuration and on-line trace ; and provides the demo source code for programmer to implement his/her applications to the business needs. The programmers easily implement their application codes by using C/C++, Delphi and BCB(Borland C++ Builder) to invoke the synchronous Application Program Interface (API)


  • International Standard Conformance: fully CCITT X.25 protocol support
  • High Speed: baud rate up to 64Kbps
  • RS-232 interface ( RS-422 Optional)
  • C/C++, Delphi and BCB programming library for X.25 protocol communication
