Figure 6. FTDI Dongle: USB Type-A at PC end and 10 Free-wires at the other end
The free wires are color-coded and numerically indexed as displayed in the following picture.
When using with Timing Commander, only four wires are used. When connecting to a customer board, connect
the Orange wire to SCL; tie the Yellow wire and Green wire together and connect to SDA; then, importantly,
connect the Black ground wire to the customer's board GND. Assuming there is a pull-up resistor for SCL and
SDA, respectively, on customer board.

By using FTDI dongle, we can connect to a customer board and use the Timing Commander GUI just like working
on a ClockMatrix evaluation board. When using the FTDI dongle to connect to a customer board, in Timing
Commander "Connection Settings" window, "On-board USB (SPI)" is selected in Connection Interface box (see
Figure 10), same as connecting to a Renesas evaluation board.
