identifying the respective PCI slots, whereas some use 11, 12, 13 and 14.
Due to this slot-dependency, it is necessary to re-configure the software driver once the
board is plugged into a different PCI slot.
Up to 4 Smartio CP-168U boards can be installed in one system. When installing more than
one board, remember the order of boards to distinguish the installed boards.
MOXA UART
The MOXA UART is an intelligent asynchronous controller that supports one full duplex
channel that simultaneously transfers data at a transmission speed of 912.6Kbps. To
increase overall data throughput, special features such as on-chip FIFO and on-chip
hardware flow control are used to reduce the number of interrupts to the onboard CPU, and
to prevent loss of valuable data.
