1. To verify the installation went correctly open the Windows
Device Manager
Scroll down to Ports,
Expand the ports by clicking on the plus sign (+), this
shows if the ports now exist on the PC.
If there are no exclamation points or other indicators of
a problem the ports should be installed correctly and
ready for use.
2. Verifying with a loopback test.
Loopback pin 1 to 2 on the terminal block connector, or
pin 4 to 5 on the RJ45 connector. (Data(-) to Data(+)).
Use the pin-out chart for the location of each pin.
Using Hyper Terminal or similar program, connect to
the VCOM port. Set the desired baud rate. Ensure
Hyper Terminal local echo is OFF. (Note: Hyper
Terminal is not provided with Vista or 2003 Server)
Transmit data. If the same character string is returned,
the test is good.
