8.3. USB Communications

Two USB ports come standard on all MagnaLOAD electronic loads. Magna-Power Electronics implements the USB protocol stack using FTDI chip set, a plug and play (PnP) device, that automatically install drivers. Connection to a computer can be established using a standard USB cable, with one end connected to the MagnaLOAD electronic load and the other to a controlling device. The communication port parameters are shown in Table 8.1. Guidelines on establishing simple serial session is discussed in USB Communications Validation.
