Signals levels are 3.3 volt UART TTL. A signal conver ter is needed in order to connect the console port to a PC. Dyacon has used FTDI TTL-232R-3V3 USB to UART converter with a modified connector. These are available from electronic component distributors, such as Mouser and Digikey. The converter is supplied with a six-pin receptacle.
