I/O circuit
Serial communication is performed by a Texas Instruments
TL16C550C single UART (Universal Asynchronous Receiver
Transmitter). Complete modem control capability is included. The
channels are RS232/RS422 compatible. For specifications refer to the
TL16C550C data sheet (available at http://www.ti.com).
The electrical characteristics (signal levels, driver currents etc.) of the
serial interface comply with the published electrical specifications for
RS232 and RS422. In addition, the board has the following
characteristics:
Parameter Value
Baud rate n Up to 115.2 kBd (RS232)
n Up to 1 MBd (RS422)
Power-up default The UART is reset.
