XTC/3 Communications Library Operating Manual
Chapter 1
XTC/3 Communications Library (DLL)
1.1 Introduction
The XTC/3 Communications Library contains functions that allow creation of a
program, for a remote PC, to control an XTC/3M or an XTC/3S instrument via an
RS232 or TCP/IP connection.
The library contains two types of functions - Communications and Command.
This document briefly describes each function, providing a prototype, arguments
and structure definitions. An example is provided for each function, with one
example shown where many functions have common prototypes.
The library consists of four files:
Š XTC3LibConn.h, which contains the declaration of the TCP/IP and RS232
communication functions.
Š XTC3Lib.h, which contains the declarations of the Data Acquisition functions
(e.g. data send and query), Status functions and Remote functions.
NOTE: These two .h files must be included in the user’s project.
Š XTCComLib.dll and XTC3ComLib.lib must be copied into the directory
containing the .exe file. The user’s project must be configured to link to
XTC3ComLib.lib .
This manual contains many variables (e.g. NUM_OF_LAYERS) that are defined in
the files listed above. Always refer to the files for the current definition of each
variable.
1.2 Communications Functions
There are two groups of Communications Functions - Serial and Ethernet - and
each group must be used to successfully establish the respective connection.
1.2.1 Setting the Serial Port
The following functions must be called sequentially — in the order of SetXTC3Port,
SetBaud, SetTimeOut and XTC3Open — to open a serial connection with an
XTC/3 instrument. The port must be closed prior to exiting the application by using
the XTC3Close function.
