RE: Recommendation for USB to Serial Port converters
Hi All Thanks for all of the replies. The device from FTDI seems to be the way to go.

Tim, I have been using cheap USB to serial converters, made by 'Planet', and they have an annoying feature/bug of the same device getting alocated a new port number if pluged into a differend USB port. This is not much of a problem if only 1 usb to serial converter is used, but I am using 4 connected to a hub. I know the reason for this 'feature', it is because the devices are cheap and only identified, by the driver, through its place in the USB tree. My question is: Does anybody know of a USB to serial converter, that doesn't suffer from the above feature, that they can recommend. I've been using USB-2COM dual port adapters - very convenient to use. USB-4COM and USB-8COM adapters are also available. You can find them all at http://www.easysync.co.uk/products.html Don't know if it will solve your problem, but at least you don't have to use more than one USB port with up to 8 devices.

My question is: Does anybody know of a USB to serial converter, that doesn't suffer from the above feature, that they can recommend. The keyspan twin adaptors do the same thing. However I merely plugged them into all the ports and then for each port configured it to have the same port name using the driver software. (ie modem and printer). I then set up the VISA.ini file to use visa serial ports 1 and 2 for modem and printer. This works fine, except for one bug in the Keyspan driver where you can't repeat this process for more than 8 ports or the configuration software locks up. I think it may be inherent that a USB device is identified by the physical location in the network. -Scott

No , I do not know, but what happens to you seems logical. Anyway, you may check to b-belect.com to see if their devices may do what you want, Thanks DC -Original Message- From: Tim Streeter [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 07, 2004 6:33 PM To: Info LabVIEW (E-mail) Subject: Recommendation for USB to Serial Port converters Hi All I have been using cheap USB to serial converters, made by 'Planet', and they have an annoying feature/bug of the same device getting alocated a new port number if pluged into a differend USB port.
