I have a TSC3 that I am trying to connect to a computer so I can update the software on it but am running into issues. I have tried both the mini usb and 9 pin connection ports but neither work. I believe it is the data collector as other data collectors have connected to my computer just fine and this same data collector successfully connected to my computer about a month ago. I have tried cleaning the ports with compressed air as well as trying different cables. Other than taking the collector in to get serviced, are they any other options to connect it to a computer or update the software that won't void the warranty? Thanks!
