2.2.2 Making the Connection
From the command prompt or a DOS box on the host PC, telnet to the IP address of the EM1500. Substi-
tute the IP address of your unit in the telnet command shown below. Use the default port number for
SER2: 8889.
telnet 10.10.6.44 8889
Assuming the host PC is running a Telnet client, you will see a connect message similar to:
At this point, everything you type from the keyboard of the host PC while connected via telnet will travel
over Ethernet to the EM1500. The EM1500 will convert the TCP/IP stream to a serial stream and send it
out SER2 which is connected to the COM port of the host PC. The keyboard entries will then appear in the
Tera Term window. You may also send files from Tera Term, by selecting File | Send file... from the Tera
Term menu.
2.3 Using the Demo Board
This section describes several ways to connect the auxiliary I/O that is available from the EM1500’s 9-pin
header to the Rabbit Engineering Demo Board that came in the Tool Kit. You will need a couple of single
wires, like those that came in the Tool Kit.
2.3.1 Select an EM1500
Open emconf or emconf.exe. As explained in the previous section, 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 infor-
mation for the unit in the area below its selection.
