•
Parallel Port Mode
—The PC industry has created several different
modes of operation for this port over the years. Usually, the default
setting works for all applications. However, if a parallel port device
specifically requires a nondefault setting, you can change it here.
The default is
Bidirectional
, for full IEEE 1284 capabilities.
•
Legacy USB Support
—Use this setting to use a USB keyboard and
mouse as if they were standard PS/2-style peripherals. You
must
enable
this setting to use these devices in operating systems with no USB
support and to boot from a USB floppy or CD-ROM. The BIOS setup
screen always works with USB keyboards regardless of this setting.
Certain real-time applications may require you to disable this setting
to reduce loop time jitter. The default is
Enabled
.
LabVIEW RT Options Submenu
Use this menu to configure boot options for LabVIEW RT if it is installed
on the controller. If you are not using LabVIEW RT, you should leave these
settings as default.
Note
These settings override the behavior of the switches on S1. Refer to the
section for more information. To use the settings from the
switches, select
Use Hardware Switch
for each option.
•
Boot Configuration
—This setting selects whether the controller
should boot LabVIEW RT, LabVIEW RT Safe Mode, or an installed
OS such as Windows XP. The default is
Use Hardware Switch
.
•
Disable Startup VI
—If the controller becomes inaccessible because
of a startup VI, this switch can prevent VIs from automatically running
at startup. The default is
Use Hardware Switch
.
•
Reset IP Address
—If the controller is deployed to a different subnet
from which it was originally configured, or if the current IP address
is invalid, use this switch to reset the IP address to 0.0.0.0 during
LabVIEW RT startup. The default is
Use Hardware Switch
.
PXI Setup Menu
Use this menu to control and route certain signals on the PXI backplane.
Normally, you do not need to modify these settings. However, other
sections of this manual may indicate that modifications are necessary
and may lead to unpredictable behavior.
•
INTP Routing
—You can route INTP to ISA IRQ 14, for use by a
PXI device functioning as a Primary IDE Controller. The default
setting is
Not Routed
.
