RS232 to USB Transmitting Data issues

    Question

  • Hello,

    We recently purchased a new Dell Computer running Windows 7 64 bit OS.  We use this computer to send/receive programs from our CNC Machines using WIN CNC.  Our new PC did not have a RS232 connection so we purchased a Staples RS232 to USB Adapter.  When we try to send data to our CNC Machines it shows that it is sending the information on the program and even the RS232 adapter light is blinking (indicating Data is being transmitted/received) but no data is received at the CNC Machine.  Whats weird is we can send programs from the CNC back to the PC and it will receive them just fine. When we hook the equipment back up to the old PC (running WIN XP and not having to use the adapter) it works just fine.  Any help would be much appreciated.

  • Purchased a native RS232 to PCI card ( http://www.newegg.com/Product/Product.aspx?Item=N82E16815158256 ) and it fixed the problem.  I guess no one makes an up to date driver to fix this issue for the USB to RS232 Serial Adapter.  Thank you for your help!

  • Budget RS232 to USB Adapter often have driver issues, which explains why it does not correctly work anymore after switching to Windows 7. Your best bet is to search for different drivers, either Vista 64-bit or Windows 7 64-bit drivers, that might work for you. What driver/driver version are you currently using?

    I assume you will not have luck with Win7 64 and USB to RS232 adapters.
    Either use the WinXP virtual machine approach or buy a native RS232
    card, for which drivers for WIn7 64 (although the builtin drivers
    should do it in most cases) exist.

    But if this PC's only use is, to send/receive programs to/from CNC
    machines, it  may be worth thinking on running this PC with Win7 32
    instead of Win7 64 as this has no issues with all those adapters.

  • Currently using the 64bit drivers offered on Staples download page (I have pasted the link below)  I have also double checked with Magic Control Tech. and they say this is the correct Driver.  I think I will end up buying a RS232 Card but am having a hard time even finding one of those that's compatible with the Windows 7 64bit OS.

  • Well buying a native RS232 card is much cheaper than buying a new OS.  Do you have any suggestions of a card that will work on the Windows 7 64bit OS?  I have looked an Newegg and not found any that say they are compatible.

    I think almost all will work e.g.
    http://www.lindy-usa.com/2-port-serial-rs-232-51187.html but I did not
    test this one as I am using the ones built into my desktops (HP Z400,
    HP 6200 MT, several other HP and Dell).

    I am having this EXACT issue right now. I see you fixed your issue. Now the only difference between your issue and mine is I am using a laptop so the PCI card you bought to solve the issue wont work for me. Do they make a solution for a laptop? PCI rs232 for laptops? Kind of needs to work for a laptop because the company already bought it. Thanks 

    PS: one more question. If i cant find a pci card for rs232 that will work for this laptop can I run a pci card intended for a desktop computer on this laptop somehow? Some adapter of some sort.

    Depending on your laptop you would probably buy an express card with a
    RS232 connector.
