USB Serial Adapter problems

[zargian]

My Dell does not have a D-9 port so I am trying to use a USB Serial Adapter (CP-US-03, http://www.cptechusa.com/cgi/products.php?cat=3&sc=30) made by CP Technologies.

I uninstalled the software (BoxCar Pro 4.3) I am using, uninstalled the driver (by Prolific), and restarted... then installed the software, plugged the device in, and let XP install the driver.

In the device manager the port is listed as "GM USB-to-Serial (COM4)." When I try to connect to the device (logger) through COM4 the software says: Logger not found. Your logger may not be hooked up correctly, you chose the wrong communictions port, your serial cable may be faulty..."

Any suggestions on anything? Would it help to change the settings for "Data bits, Parity, Stop bits, Flow Control" and if so, is it a stab in the dark or is there a way to make an educated guess.

Also, I just realized the company, OnSet (www.onsetcomp.com) sells and suggests using this adapter (http://www.keyspan.com/products/usb/USA19HS/).

Is there that big of a difference? Why would two adapters be that different? Isn't there a way to configure my adapter to work like the Keyspan adapter?

Thanks in advance

Hi, the reason could be that your device is looking for a different COM port number, for example COM port 1 instead of COM port 4. If you right click on the created port in Device Manager and chose Properties then you can change the COM port number.
Regarding the difference between the adapters, the main difference is which chipset the adapter is designed with, my experience is that USB to Serial adapter cables with a FTDI chipset are compatible with most devices and the easiest to setup and use.
