button to set up a board with correct "Board Type", "IRQ", "INT
Vector", "I/O Address", "COM Number" and "Received FIFO Trigger Level",
where the possible parameters are as follows:
Board Type:
C104, C168 Family.
IRQ:
2, 3, 4, 5, 7, 10, 11, 12, 15.
INT Vector:
I/O address for interrupt vector from 00000H to 0FFFFH. To use INT
vector, type in the hardware INT vector I/O address. If not using INT vector, type 0
or leave blank as the INT vector.
There are two modes for the C114HI driver. One is using INT vector, the other is
not using INT vector. INT vector is one byte of I/O address, in which each bit is
used to indicate the occurrence of interrupt for corresponding port. Driver
employing INT vector scheme is supposed to have better performance than
employing polling scheme.
Sequential Port Mapping:
For I/O Address, specify the I/O address of the first port
and subsequent ports are set to continuous I/O addresses by the offset of 8 bytes. For
instance, if the first port is set to 0x180, then the second port is set to 0x188
sequentially. For COM number, specify the COM number of the first port and
subsequent ports are mapped to continuous COM numbers. For instance, if the first
port is mapped to COM10, then the second port is mapped to COM11 sequentially.
For receive FIFO trigger level (bytes), every port will have the same trigger level as
set. For 16550-compatible type of UART, receive FIFO trigger level is 1, 4, 8 or 14
bytes. The default is 14 bytes.
Non-sequential Port Mapping:
For I/O Address, set the I/O address of each port
independently. For COM number, set the COM number of each port independently.
For receive FIFO trigger level (bytes), set the trigger level of each port
independently. For 16550-compatible type of UART, receive FIFO trigger level is 1,
4, 8 or 14 bytes. The default is 14 bytes.
At most 4 boards of C1114HI can be installed together as long as the IRQ and I/O
port resources are sufficient and available in a system.
Unless the system restarted, the latest configuration will not take effect.
