1.
Properly connect STE-501C hardware including power, Ethernet and serial cable
2.
Properly configure the parameters of STE-501C including connection type, IP address, gateway IP
address, and network mask accordingly (see chapter 3
Hardware Installation
section).
3.
Configure STE-501C as TCP Server using default TCP port number 4660.
4.
The host (PC) application program must be configured as a TCP client and connects to STE-501C with
designated TCP port number 4660 for COM1.
5.
Make sure STE-501C is running by checking the running status through
monitor.exe
configuration
utility.
6.2 Running the Sample Program
Sample programs written in VB and VC++ included in package are provided for oner reference, source
codes are also included. Test program can be found in the product CD or diskette under the directory of
\sample\vb_ap\
and
\sample\vc_ap
respectively.
There are two test programs, TCPTEST written in Visual Basic and TCPTEST2 written in Visual C++.
6.2.1 TCPTEST in Visual Basic
This sample program is written in Visual Basic 5.0 with Winsock Controls. It shows one how to send and
receive data between host (PC) and STE-501C via Ethernet in two socket ports.
Run Visual Basic and open sample program tcptest.vbp, after the program is started successfully, one can
start testing functions (Figure 6.1). For more information, please press
Help
in the program to get detail
explanation.
Note
: Please be sure the Microsoft visual studio family software is installed on the computer. Otherwise
the sample program will not run.
