2.8 DMA Channel Setting
The A/D data transfer of ACL-8316/12 is designed with DMA transfer
capability. The setting of DMA channel 5, 6 or 7 is controlled by the jumpers
JP1 and JP2. The possible settings are illustrated in the Figure 2.7 below.

2.9 IRQ Level Setting
The ACL-8316/12 can connect to any one of the interrupt lines of the PC I/O
channel. The interrupt line is selected by the jumper JP3. If you wish to use
the interrupt capability of ACL-8316/12, you must select an interrupt level and
place the jumper in the appropriate position to enable the particular interrupt
line.
The default interrupt level is IRQ15, which is selected by placing the jumper
on the pins in row number 10. Figure 2.8 shows the default interrupt jumper
setting IRQ5. You only remove the jumper from IRQ15 to other new pins, if
you want to change to another IRQ level.
Note: Be aware that there is no other add-on card shares the same
interrupt level at the same system.
