The factory sets the switches for memory address C000(hex) for an IBM
PC AT or other machine with a 16-bit bus. If you’re running on a PC XT
or another 8-bit bus machine, or if you want to configure the scanner at an
address other than C000(hex), you’ll have to change the switches.
First set switches 7 through 10 to all closed for a PC AT or similar, all open
for a PC XT or similar. The factory setting is all closed, for a PC AT or
other machine with a 16-bit bus.
Next set switches 1 through 6 for the memory address you selected.
Table 3.C shows the correct setting of switches 1 through 6, in that order,
for every hex address below F000, where
O is an open switch and c is a
closed switch:
