IBM’s Technical Reference Manuals show line IRQ3 used by the
secondary serial port (COM2 device). If you have 2 serial ports active on
your host computer and you have selected IRQ3, you must disable COM2
before installing the scanner board. (Many multi-junction cards have
jumpers to disable this port; see your manufacturer’s documentation for
details.)
CAUTION: If you have other cards that use the interrupt line
you have selected, (IRQ3, IRQ5, IRQ10, or IRQ12), physically
disconnect them to avoid damaging the 6008-SI or other cards.
To change the interrupt request line setting, complete these steps:
1. Remove the cover from the computer that contains the I/O scanner.
2. Remove the I/O scanner from the computer.
3. Remove the four screws securing the daughterboard to the main
board. Unplug and remove the daughterboard.
4. Locate the double row of stake pins on the main board (see
Figure 3.1). A jumper plug connects 2 pins to select the interrupt
request line.
