A-2 Smartio C168H/PCI User’s Manual

referred to as slot-sensitive or slot-dependent, and may apply to PCI slots in PCs with

different motherboards and different device number sets. For example, some use 17,

18, 19, and 20 for identifying the respective PCI slots, but some use 11, 12, 13, and 14.

Due to slot-dependency, it is necessary to re-configure the driver software once the

board is plugged into a different PCI slot.

Up to 4 Smartio C168H/PCI boards can be installed in one system. When installing

more than one board, remember the order of boards to distinguish the installed

boards from each other.

UART 16C550C

The UART 16C550C chip is an intelligent asynchronous controller supporting one

full duplex channel that simultaneously transfers data at 921.6 Kbps speed. To

increase the 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.
