Moxa Technologies C168P user manual Hardware Installation with IO-IRQ Utility

Hardware Installation

5.DO power OFF and then ON (or Reset) the PC. (Please cold start.)

6.Restart System (Windows NT/95/98).

It is very important to keep the JP1 always short in this case. Without running the hardware configuration program, Io-irq.exe under DOS prompt, the software configuration program will automatically update the hardware settings of the board while updating the software settings. This saves the trouble doing hardware configuration. However, remember to cold start the system every time the configuration changed.

Hardware Installation with IO-IRQ Utility

This section is for those who can not use quick hardware installation:

uInstall two or more C168P boards in a system.

uFail to install, due to the I/O address 0xA700 is not available or has conflict in the system.

uUse operating systems other than Windows NT and 95/98.

Before proceeding the software installation, detailed in the next chapter, “Software Installation”, do hardware configuration to setup the I/O address and IRQ with “Io-irq.exe”, detailed in the next section.

Remember to keep the hardware settings in mind for the software installation.

The C168P has the following default (factory) settings:

I/O address : 0x180 (Port 1), 0x188 (Port 2), 0x190 (Port 3), 0x198 (Port 4) 0x1A0 (Port 5), 0x1A8 (Port 6), 0x1B0 (Port 7), 0x1B8 (Port 8)

IRQ : 10

INT Vector : 0x1C0

Because the ASIC-designed C168P 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.
