Testing with a Telnet Connection
One quick way to test the functionality of your Serial-to-Ethernet connection is with the Telnet program
and an RS-232 Serial terminal program (e.g. MTTTY). Remember you must use a NULL modem able to
connect your SB72EX to your host computer. To run this test, configure your system as one of the two
examples shown below:
The objective of this example is to use a single host computer running telnet and a serial terminal program
to send data in either direction. Therefore, if you type text in the telnet window, it should appear in the
serial terminal window and visa versa. For a serial terminal, you can use MTTTY (which can be
downloaded from the SB72-EX product page at www.netburner.com) or HyperTerminal.
In the following example, an IP Address of 10.1.1.79 will be used for the SB72EX. Note: Replace this
number with the specific IP Address you assigned (if using a Static IP Address) during configuration.
Procedure
SB72EX User's Manual, 350030-001
1. Connect your hardware in one of the above configurations.
2. Open a command prompt window on your host computer.
3. Verify everything is connected correctly by executing the command ping 10.1.1.79 and pressing
4. Run either HyperTerminal or MTTTY. Set the baud rate to the value you assigned to the SB72EX
the Enter key on your keyboard. You will see a valid ping response. Remember to substitute your
IP Address for our example IP Address (i.e.10.1.1.79).
during configuration. To use MTTTY (with the factory default settings):
Connect your NULL modem cable from Port 0 on your SB72EX to your host computer’s
serial port. Remember, a standard serial cable will not work.
Run MTTTY (Mttty.exe) by double clicking its icon. This application can be downloaded
from the SB72-EX product page at www.netburner.com. When the MTTTY window
appears use the factory default setting shown below:

The Port setting is the communication port that you connected the NULL
modem cable to on your host computer.
The host computer and the attached SB72EX must agree on a speed or baud rate
to use for the serial connection.
Parity checks whether the data has been lost or written over when transmitted
between your host computer and your SB72EX.
