2.6.2 PC I/O Map
The standard PC/AT I/O map assignments are listed below.
I/O addresses 000
16
to 0FF
16
are reserved for the PC system board use and I/O
addresses 100
16
to 3FF
16
are available on the I/O channel. The installation of the
PC215E at a base address that uses unlisted ports may result in conflicting assignments
with third party adapters.

2.6.3 Selection of Interrupt Request (IRQ) Level
Selection of the required Interrupt Request Level is by means of a jumper in a single position on
header J1. Eight levels are available, but only one of these may be selected, and a level should
be chosen that does not conflict with any other assignments within the host computer.
The factory default setting is IRQ level 5.
The following table shows the available levels on the PC215E and normal usage of all hardware
interrupts. The one of eight position jumper is illustrated in Figure 4.
