Setting The Base Address - Keithley DAS-8 Series User Manual

Setting the Base Address

DAS-8 Series boards are shipped with a base address of 300H. If any of
the address locations between 300H and 307H are being used by another
resource in your system (including another DAS-8 Series board), you
must reconfigure the base address using the base address switch block
(labeled S1 on the DAS-8/LT board; labeled S2 on DAS-/PGA(G2) and
DAS-8/AO boards).
To change the address, refer to the DriverLINX Appendix F:
Note:
Configuration and Implementation Notes — Keithley DAS-8 manual.
The base address switch block contains seven switches, labeled 1 through
7. Switch 1 corresponds to the most significant bit (MSB) of the base
address; switch 7 corresponds to the LSB of the base address. The
location of the base address switch block on the DAS-8 board is shown in
Figure 3-1; the location of the base address switch block on the DAS-8/LT
is shown in Figure 3-2; DAS-8/PGA(G2) boards is shown in Figure 3-3;
and DAS-8/AO is shown in Figure 3-4.
You place a switch in the ON position (logic 0) by sliding the switch
toward the top (numbered side) of the switch block. You place a switch in
the OFF position (logic 1) by sliding the switch toward the bottom
(unnumbered side) of the switch block.
Figure 3-5 illustrates the setting for a base address of 280H; switches 1
and 3 are in the OFF position and switches 2, 4, 5, 6, and 7 are in the ON
position.
