New : set I/O address and IRQ via software Utility.

Traditional : set switch and and jumper manually for I/O address and IRQ.

Instead of using traditional jumper or switch for IRQ and I/O address settings, hardware configuration of each port is easily set by DOS utility, Io-irq.exe, which reads and writes the on-board EEPROM for configuration information through the CAP (Configuration Access Port) address. The CAP address is the only channel via which the configuration utility Io-irq.exe can access the board, which is identical to the first port's base I/O address.

The only jumper, JP1, is designed in case that users forget the CAP address. Normally JP1 is left open. When JP1 is short, the CAP address is forced to a fixed I/O address, 0xA700. However, to adopt quick installation (described later), it is a must to keep JP1 always short.

Quick Installation

To ease the hardware configuration, users who install only one C168P board under Windows NT/95/98 are recommended to adopt quick installation described in Chapter 2.

Because the family is so flexible in hardware configuration that they are compatible virtually with all kinds of other manufacturer's multiport boards using 16450 or 16550 UART.
