    Vista Laptop USB RS 485 Converter

    I can't get a USB x RS485 converter to work on a Vista laptop. I've tried Belkin and another brand. Anyone have any suggestions?

    I've also tried a TCP IP x RS485 converter (BF-430) without success.

    You dont have a seral port?? I am using vista and it works fine. I think the Dell Latitude is one of the few that still put a seral port in.

    Try a Digi Edgeport/1, it is a USB/Serial converter, they are expensive ($90.00-$100.00) but they come with a utility (in the Win98 folder) on the CD to assign the device to a specific COM port. Then use an RS-232/RS-485 converter (B&B Electronics p/n 485SD9TB). I haven't tried it with Vista but they always work on XP laptops w/o serial ports. I haven't had any luck with a USB to RS-485 adapter, the above works (on XP).

    Your problem may be that Vista assign's the adapter to a random COM port. Some software requires a specific COM port (like HVAC-Pro from JCI, COM1 or COM2 Only !). The 2 device thing is expensive but you can always use the 232/485 with a regular serial port.

    We have stayed with XP simply because none of the major Mfgrs support Vista 100%, you may have to setup something to be able to use XP on those laptops, dual boot/virtual machine. Ask an IT guy what your options are.
    If sense were so common everyone would have it !

    Any advice provided is worth exactly what you paid for it, not a penny more not, a penny less !!

    This might help

    I've used the USB-COMi-SI-M with Win XP but you can find a Vista driver for it. Here is the web page for it

    My Trane Rover kit came with a USB to RS-485 converter. (Actually, it's a USB to RS-232 and a RS-232 to RS-485 converter in one package.) Since I use PCMCIA RS-485, I let another co-worker use it on his Vista laptop, and it works with no problems. If I ever get my hands back on it, I will try to dechiper who made the darn thing. (Like Quatech makes the RS-485 card, and Echelon made the Lon adapter.)

    Do it right the first time, and you will not have to do it again.

    B&B Electronics makes the Edgeport but they also have a straight USB to 485/422 converter. The part number is USPTL4. They also have an optically isolated one. They are very expensive ($120 for the USPTL4 and $140 for the isolated), but they work well. I use mine to do everything from troubleshoot MS/TP busses to download N2. The datasheet says that it works with Vista.

    Thanks for all the help.

    I'm still investigating all of these.

    I did get the Vista drivers for the Keyspan USB x 232 from Tripplite.com I connected a 232 x 485 converter made by 3One Data Communications Tech and also to a converter made by ICP.com.

    Both these converters work connected directly to a serial port running XP.

    When I connect the converters to the USB x 232 converter on the Vista machine it will receive data from my device but I get an error when I send data.

    Any additional help is appreciated
