Testing a DB-9 RS-232 serial port in HyperTerminal
This procedure explains how to troubleshoot a COM card using Hyperterminal. Before testing your serial ports, you must first hook up a loopback.
A loopback connects the output signal (TxD) to the input signal (RxD) in a single serial port connector to make it seem like there are two ports connected together.
Making a loopback
Step Procedure Description
Step 1 Turn off the computer.
Step 2 Connect RxD (pin 2) and TxD (pin 3) of the serial port. Use a loop-back connector if available, or any kind of conductive wire, even a paper clip.
Step 3 Turn on the computer. You are now ready to test the port. Figure 24 - RS-232 DB-9 connector
Running Hyperterminal
Step Procedure Description
Step 1 Launch HyperTerminal. In Windows,
select Programs/Accessories/ Communications/ HyperTerminal.
Step 2 Create a new session. When prompted, give the session any name you wish.
Step 3 Select the COM # associated with your You are now set up to test the port. port from the drop down list. Note: Leave all settings at default. Figure 24 illustrates the jumper location for a loopback on a RS-232 DB-9 connector. Install a wire jumper to connect the following signals: RxD (pin 2) to TxD (pin 3) Step Procedure Description
Step 4 With the session open, type any text. If the text you type is echoed on the screen, the port is functioning properly.
Step 5 Close the session. Step 6 Repeat all above steps to test additional You will first need to connect the Loopback ports. on the other ports using the steps above
