Troubleshooting
Here are some common questions and answers intended to help you resolve any problems
you may have with the USB-to-Serial Adapter. For additional information please check the
support section at www.socketserial.com.
WHAT IF I HAVE A DIFFERENT OPERATING SYSTEM?
As we develop support for additional operating systems we will post drivers for download at
www.socketserial.com
.
MY RS-232 CABLE DOESN’T FIT TO THE USB-TO-SERIAL ADAPTER
Serial RS-232 (EIA-232) cables usually have either 25-in or 9-pin connectors. The USB-to-Serial Adapter
has a male DB9 connector (sometimes called “DB9M” or more accurately “DE-9 male”). It is designed
to connect to RS-232 cables that have a female DB9 connector. If your cable does not fit the USB-to-
Serial Adapter it may require either a 25pin-to-9pin adapter or a gender adapter. Adapters are
commonly available at consumer electronic stores.
THE STATUS LED FLICKERS
This is normal; it indicates that data is moving through the USB-to-Serial Adapter.
THE STATUS LED DOES NOT COME ON
When you connect the USB-to-Serial Adapter to a USB port of a computer the status LED should come
on. If you do not see the LED check these items:
1. Make sure the driver has been installed onto your computer. If the driver has not been installed
some computers will not supply power to the USB-to-Serial Adapter
2. If the USB-to-Serial Adapter is connected to a USB hub, then try connecting it directly to your
computer. Some USB hubs do not fully comply with the USB spec and may not have sufficient
power to operate the USB-to-Serial Adapter
THE DRIVER INSTALLATION DOES NOT START WHEN I INSERT THE CD-ROM
Find and execute the setup.exe program on the CD-ROM
I’M UNABLE TO INSTALL THE DRIVER, OR THE DRIVER SETUP PROGRAM DOES NOT COMPLETE, OR THE
DRIVER SETUP PROGRAM COMPLETES WITHOUT CREATING THE COM PORT
Here are some things to check before trying the setup program again.
1. Check if there is a more current version of the software on www.socketserial.com
2. Try connecting your USB-to-Serial Adapter to a different USB port
3. Check Windows Device Manager to see if the device "Socket USB-Serial Adapter" is present
