FTDI (USB Serial)
An FTDI FT4232 serial to USB interface chip is implemented on the board to allow an external PC
to interface to the following serial interfaces:
•
GR716 DSU serial interface
•
GR716 UART-0 serial interface
•
GR716 UART-1 serial interface
•
FMC JTAG interface
The front panel interface connector (marked ‘ FTDI’ on the front panel) is a standard USB Micro-AB
style connector.
