    COM port address for USB to serial converter (case 17709)

    Hi all,
    I'm trying to set up DirectRT to communicate with physio equipment (iworx). So far IO test sends signals well, however I cannot determine the appropriate decimal address for the virtual COM port. This is needed for the excel file. I can't find anything helpful in device manager. Any input is greatly appreciated!

    If the problem is identifying the proper address of the port, try these steps:

    1) Click the Start button.
    2) Click on Control Panel.
    3) In that Control Panel window, click on Device Manager.
    4) Click on Ports to expand it and double-click on the specific port for which you want to know the address.
    5) Click the Resources tab in the new window. Look for the entry that reads I/O Range. To the right of it in the Settings column you will see a potential range of port address in hexidecimal value (e.g., 60E0 to 60E7). If you put them individually in a hex to decimal converter like this one http://www.binaryhexconverter.com/he...imal-converter you should get the decimal values. You can then try each of these decimal values in your DirectRT .csv input file to see if it sends the ttl signal value defined in your stim column to your external devices.
