DIP Switch Settings
The RS-422 circuit board is a standard circuit card for a commercial PC. Because this
board is designed for a number of different operating systems it has some designed in
flexibility. See Figure 3-25. All factory settings of the DIP switches are identified.
This circuit card has two sets of DIP switches, an eight-position switch used to select
the IRQ, and a four-position switch that selects the I/O address and extended memory
enable. The factory default settings for the PDR100 are all off, except for position
eight (which selects IRQ 15).
