Switch S1
How to set
S1-1 8 (hex)
S1-2 10 (hex)
S1-3 20 (hex)
S1-4 40 (hex)
S1-5 80 (hex)
S1-6 100 (hex)
S1-7 200 (hex)
S1-8 400 (hex)
300 (hex) is the
default base
address
Description
Switch S1 sets the card address on the PC/104 bus. The selected card address
is the additive value of the switch settings indicated to the left. Moving the
switch to the ‘off ’ position adds that value to the final base address. For
example, to select a base address of 340 (hex), the following switch settings
would be selected:
S1-1
on
S1-2
on
S1-3
on
S1-4 off
S1-5
on
S1-6 off
S1-7 off
S1-8
on
The card address selected using S1 must match the address expected by your
software. In addition, this address must not be used by other cards. From the
base address selected, 8 addresses are used by the Navigator-PC/104 card. For
example if 300 (hex) is selected, then locations 300 - 307 will be used by the
card, and cannot be used by other cards on the bus.
