A communications program such as Windows HyperTerminal.
Connecting the Serial Cable

The serial menu will appear after the diagnostic check completes. If unrecognizable characters appear, the baud rate set on the UltraMatrix switches serial port and the baud rate set on your computers COM port are not set to the same value. Disconnect from the UltraMatrix by clicking on the “Disconnect” ICON. Change the baud rate on your terminal or computers communication program from 9600 (set previously) to 57,600.
