Smartio C168H/PCI User’s Manual
which may be called slot-sensitive or slot-dependent. This may also apply to PCI
slots in PC with different motherboard, which may use 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 the slot-dependency, it is necessary to re-configure the software driver
once the board is plugged in different PCI slots.
Up to 4 Smartio C168H/PCI boards are allowed in one system. When installing
more than one boards, please remember the order of boards for distinguishing the
installed boards.
UART 16C550C
The UART chip 16C550C 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 any loss of valuable data.
