I can connect to my DriveRack 480 with a USB to Serial adapter. What is wrong?
Not all adapters will work with the ZonePRO products. One brand in particular, has been the Belkin. Some will work with some computers and not others. Please take a look at this RS232 compatibility document for more information on these adapters. Also, see the RS232 to Serial troubleshooting document or the DriveWare USB to Serial Adapter Troubleshooting Video for some troubleshooting ideas.
