Why can't I establish a connection with AmpTraXX?

First, verify that you are using a straight-through (not NULL) RS-232 cable like the one provided with AmpTraXX.  

Next, make sure that you have the correct COM port selected in the AmpTraXX configuration menu. If you are not sure which COM port your PC's external serial port is using, just use trial and error to figure it out.  

If you still cannot connect, contact Technical Support.
