2.6 Analog Input Channel Configuration

The ACL-8216 offer 16 single-ended or 8 differential analog input
channels. The jumper JP3 controls the analog input channel
configuration. The settings of JP3 is specified as following
illustration.

2.7 DMA Channel Setting

The A/D data transfer of ACL-8216 is designed with DMA transfer
capability. The setting of DMA channel 1 or channel 3 is controlled by
the jumpers JP8 and JP7. The possible settings are shown below.

Note: On floppy disk only machine, we suggest you to set DMA level 3. If

you have hard disk equipped computer, level 1 is preferable.
