We have got two 60 GHz evaluation kits EKIT01-HMC6450. The accompanying software "Hittite Microwave 60 GHz Control Panel - Revision 1.0.6" uses USB to communicate with the kit but it is not possible to select which USB serial port to use. It is not possible to have two kits connected to the same PC and the kit will also interfere with various other hardware using USP to serial conversion. Is there an updated version of this application or is there another way to circumvent the problem. Or is the serial port protocol documented so that we could write our own application to setup the boards.
