How to Use the Board
COM-2(PC)F14
Operating under Windows 2000
This section describes the procedure for using the board under
Windows 2000 and lists a number of points to note.
Procedure
When using the board under Windows 2000, the OS must be set to
recognize the I/O address and interrupt level used by the
COM-2(PC)F. In Windows 2000, this is called hardware
installation. Use the following installation procedure.
Check the Current Settings
First, check the current settings. Check which interrupt levels are
available. If using in Compatible mode, also check which COM
ports (COM1 to COM4) are already set. The COM-2(PC)F cannot
be assigned to a COM port that is already set. The procedure for
checking is as follows.
- Check the interrupt level
1. Select [System] from [Control Panel] and click [Hardware]
property sheet, then open [Device Manager].
2. Select the [View] and click [Resource by type].
3. Display the [Interrupt request(IRQ)] list and check which
interrupt levels are available.
- Check the ports
1. Select [System] from [Control Panel] and click [Hardware]
property sheet, then open [Device Manager].
2. Double click on the [Ports (COM & LPT)] [Infrared], [Modem]
folder and check which ports are already set.
