Installing Under Windows NT

Installing WCSC's HDWPCOM816550 multiport card under Windows NT is simple. This procedure will assume that the board is installed at 100 hex and IRQ 5. It will also be assumed that the board's first port will be COM3. Adjust the installation according to your hardware setup.

1. Open the Control Panel Under Windows NT.
2. Click on the Ports Icon.
3. Click the Add button.
4. Change COM Port Number: to 3 plus the zero based port number on the multiport card(e.g., 3, 4, 5, 6, 7, 8, 9, 10).
5. Change Base I/O Port Address: 100 plus the zero based port number times eight on the multiport card(e.g., 100, 108, 110, 118, 120, 128, 130, 138)
