NPort 5000AI-M12 Series IP Serial Library
7-2
Overview
What is IP Serial Library?
IP Serial Library is a Windows library with frequently used serial command sets and subroutines. IP Serial
Library is designed to reduce the complexity and poor efficiency of serial communication over TCP/IP. For
example, Telnet can only transfer data, but it can’t monitor or configure the serial line’s parameters.
Why Use IP Serial Library?
For programmers who are familiar with serial communication, IP Serial Library provides well-designed function
calls that have the same style as Moxa’s PComm Library.
IP Serial Library is amazingly simple and easy to understand. By including it in your VB, C, or Delphi
programming environment, you can program your own TCP/IP application with the ability to control serial
communication parameters.
NPort 5000AI-M12 serial device servers use 2 TCP ports for communication between the NPort 5000AI-M12
and host computer’s Real COM driver. The NPort 5000AI-M12 uses a data port and command port to provide
pure data transfer without decode and encode. Compared to using only one TCP port to control serial
communication (such as RFC2217), IP Serial Library uses a command port to communicate with the NPort
5000AI-M12 in user’s program. IP Serial Library not only runs with excellent efficiency but also runs without
any decode or encode problems.
How do I install IP Serial Library?
IP Serial Lib comes with the NPort 5000AI-M12 Administration Suite. Refer to the IP Serial directory for more
detail about the function definitions.
