Setting The Interrupt Level - Keithley DAS-800 series User Manual

Setting the Interrupt Level

3-14
You place a switch in the ON position (single-ended) by sliding the
switch toward the top (numbered side) of the switch block. You place a
switch in the OFF position (differential) by sliding the switch toward the
bottom (unnumbered side) of the switch block.
Figure 3-4 illustrates the setting for channels 0, 5, and 7 configured as
single-ended (switches 1, 6, and 8 are in the ON position) and channels 1,
2, 3, 4, and 6 configured as differential (switches 2, 3, 4, 5, and 7 are in
the OFF position).

Figure 3-4. Setting the Input Configuration
Since DAS-800 boards always use a single-ended input
Notes:
configuration, they do not contain an input configuration switch block.
DAS-800 Series boards are shipped with interrupts disabled. If you want
to use interrupts, you must set an appropriate interrupt level using jumper
block J1.
DriverLINX modes specify preferred hardware data transfer
Notes:
techniques: Foreground or synchronous modes, Background or
asynchronous modes. DriverLINX supports three modes with the
DAS-800 Series for its commands: Polled mode, Interrupt mode, and
Other mode. Refer to the Using DriverLINX with Your Hardware—
Keithley DAS-800 manual.
If you intend to acquire data in the background, you must enable
interrupts by setting an interrupt level.
