Check the software driver installation

Usb Rs232 Adapter Driver Windows 7
- Windows Vista: Start >> Control Panel >> System >> Hardware >> Device Manager
- Windows XP: Start >> Control Panel >> System >> Hardware >> Device Manager
- Windows 2000: Start >> Settings >> Control Panel >> System >> Hardware >> Device Manager
- Windows 98/ME: Start >> Settings >> Control Panel >> System >> Device Manager
2) Click the plus sign (+) next to 'Ports'.
3) If the device is properly installed, 'Serialio.com USB Serial Port' or 'Prolific USB-to-Serial COM Port' will be displayed.
The software driver is properly installed, but the USB-RS232 adaptor does not work as expected
One of the common reasons that software may not work as expected with a USB-Serial adaptor when the devcie is properly installed, is many older programs (and even some new ones) only support a limited number of COM ports (e.g. only COM1 - COM4)
If the USB-RS232 adapter is installed as COM5, it may need to be reassigned to COM1 - COM4 to work with some software.
The following outlines how to to reassign the COM port on Windows XP/2K/Me/98SE
Windows XP
1) Follow steps 1-3 of 'Check the software driver installation'above.
2) Right-click on the 'Prolific USB to Serial Port', then click Properties
3) Click on the 'Port Settings' tab. Click the 'Advanced' button.
4) In the 'COM Port Number' drop-down select the desired port number. For example if the software requires COM2, select COM2. Note the COM port must have '(in use)' listed next to it, if it does then another device with that name is already installed in the system. After selecting the desire port number, click 'OK.'
5) Click 'OK' again, and the device will show up as being on the same COM port that it was before (i.e., COM5), but should show up on the selected port name when the Device Manager dialog is closed and opened again.
6) Close the Device Manager. Launch the software to use with the new COM port.
