Moxa Technologies C168HS user manual IO-IRQ Utility and Hardware Configuration

Because the ASIC-designed Smartio C168 Series has no switch and no jumper for configuring manually the I/O address, IRQ, INT vector, etc. of the boards, you must run the software utility, Io-irq.exe, in the driver diskette under DOS system to change the hardware configuration.

1.Choose a PC that has DOS system inside.

2.Power off the PC.

3.Make sure no hardware conflict and plug the board in a free 16-bit slot of the PC, one board at a time with JP1 open.

+If you are installing multiple boards, insert one board at a time and configure it using the Io-irq program before inserting the next board. This is to prevent conflict between two boards with same default hardware settings.

The Smartio C168 Series has the following default (factory) settings,

I/O address: 0x180 (Port 1), 0x188 (Port 2), 0x190 (Port 3), 0x198 (Port4) 0x1A0 (Port 5), 0x1A8 (Port 6), 0x1B0 (Port 7), 0x1B8 (Port 8)

IRQ: 10

INT Vector: 0x1C0

Configuration Access Port (CAP): 0x180

4.Power on the PC and enter into DOS system.

5.Run the utility “Io-irq.exe” contained in the driver diskette to set up I/O address, IRQ and INT vector of the board. Please refer to the next section, “IO-IRQ Utility and Hardware Configuration” for more details. Or follow the on-line help to configure the Smartio C168 Series board.

After completing the hardware configuration, the board is ready for use under operating systems, such as Windows NT and 95/98, DOS, UNIX etc.

Note that the CAP address, e.g. 0x180, is identical to the first port's I/O address except in one case that the JP1 jumper is installed before powering on the PC. In this case, the CAP address will be forced to 0xA700. The CAP address must be
