2.2 Up and Running
A simple block diagram of the example is shown below.
Figure 2.1 Host PC connected to an EM1500
There are two software programs that run on the host PC for this example:
•
a terminal emulator
•
emconf.exe (Windows) or emconf (Linux), the stand-alone configuration program located on the
CD in the EM1500 Tool Kit.
If there is a DHCP server on the same LAN as the host PC, you will not need to make any configuration
changes on the EM1500. Otherwise, you will need to statically assign an IP address to the EM1500. Please
see
Chapter 3, “Assigning an IP Address to the EM1500,”
for directions on how to accomplish this.
2.2.1 Serial Port Configuration
Open any terminal emulator program. In this example, we will use Tera Term. Choose a serial connection,
then select the COM port that is connected to the EM1500. Go to the Setup menu and select “Serial port
...” to bring up the “Serial port setup” dialog. The serial port geometry (e.g., 8N1: character size is 8 bits,
there is no parity and there is one stop bit.) and speed are set in this dialog. If you are using some other ter-
minal emulator, the process might be slightly different, but each one has a dialog box that lets you set
serial port parameters. The defaults in Tera Term are probably 8N1, no flow control and the baud rate is
9600 bps. Change the baud rate to 19200 bps and click on OK.
Open
emconf
or
emconf.exe
. This program will try and discover any EM1500s that reside on the
same LAN as the host PC. You should be able to see the EM1500 on the upper left side of the program
window. Click on its icon; this highlights the entry and shows status information for the unit in the area
below its selection. The entry includes the IP address if DHCP was successful.
