Plus Network 4 Board (250-1019) Settings Faxback Doc. # 5393 Jumper location J1 selects the interrupt that is to be used. Be sure the jum- per is set to interrupt 3 (IR3) as this interrupt is recognized by the soft- ware. This board uses I/O PORT address 248-24F Hex. Dip switch SW 1 selects the station number. The settings on the DIP switches are a binary encoding of the numbers 0 to 63 (decimal). Each switch repre- sents a digit in the 6 bit binary number. A switch set to down or OFF equals bit ON or binary "1". Switch SW 1-1 is the least significant bit. The soft- ware currently selects station 63 as the disk server, use 0-62 for work sta- tions. *NOTE: IRQ#3 is the same interrupt request as a COM 2 device. (css 08/03/93)
