78M6613 PSU Board User Manual
Note that port parameters can only be adjusted when the connection is not active. It may be necessary to
click the Disconnect Button to disconnect the port.
FTDI COM Port Trouble-Shooting
The 6613_PSU_S1_URT_V1_0 firmware defaults to an Auto-Reporting mode. Auto-reported AC
measurement data packets consisting of Voltage, Current, Watt, Power Factor and Line Frequency are
sent every accumulation cycle. Measurement data packets are sent over the UART in ASCII format
followed by a line feed and carriage return.
Table 3 lists the measurement parameters and their respective bit resolutions (LSB) that are sent over the
UART in ASCII format.

If the FTDI device driver did not install properly, there would be no assigned COM port
number for the FTDI controller. Repeat the USB Driver Installation, see Section 2.1.
Microsoft Windows may associate a Ball Point device to the FTDI USB controller. When this
occurs a FTDI device COM port assignment is available via HyperTerminal but there is no
communications data. Verify if a Ball Point device has been added to the “Human Interface
Devices” via the Device manager. Refer to Section 2.2 for access to the Device Manager. If a
Ball Point device exists, delete it and unplug and replug the evaluation board’s USB cable.
