Functional description
The NT8D41AA SDI paddle board has two asynchronous serial ports.
These serial ports are connected to the I/O panel in the back of the shelf
using special adapter cables. The serial ports can be used to connect the
system to a terminal, a printer, a modem, or to an other system processor.
The SDI paddle board contains two Universal Asynchronous
Receiver/Transmitters (UARTs) and the logic necessary to connect the
UARTs to the system processor bus. See
