2.5.7 UARTs for Terminal/Logging

Six UART ports are provided for terminal and logging functions using two UART-over-USB transceivers. When the USB micro-B connectors [J48] or [J49] of the EVM are connected to a Host-PC using supplied USB cable (Type-A to Micro-B), the computer can establish Virtual Com Ports to be used with any terminal application. Virtual Com Port drivers for the transceivers can be obtained from FTDI Chip.

Once installed, the Host-PC creates the Virtual Com Ports (two ports for FT2232, four ports for FT4232). Depending on the other Host-PC resources available, the Com Ports are not located at COM1-2 or COM3-6. However, the ports remain in the same numerical order for each transceiver.

The circuits are powered from USB bus power and therefore the COM connection are not lost when the EVM power is removed. LEDs [LD11] [LD12] are used to indicated an active COM connection with Host-PC. The EEPROM of FTDI bridges are programmed with the EVM serial number, allowing users to identify the connected COM port with board serial number when one or more boards connected a single computer.

Note: The maximum length for the IO cables must not exceed three meters.
