Serial/Parallel Port Configuration Submenu
Use this submenu to apply alternate configurations to the serial and parallel
ports. Normally, you do not need to modify these settings, as the factory
default settings provide the most compatible and optimal configuration
possible.
• Serial Port1 Address—This setting specifies base address and
interrupt request level (IRQ) information for COM1. The setting can
also be used to disable COM1. The default value is 3F8/IRQ4, which
places COM1 at 0x3F8 IRQ 4.
• Parallel Port Address—This setting specifies the base address for
LPT1, the parallel port. The setting can also be used to disable LPT1.
The default is value is 378, which places LPT1 at 0x378.
• Parallel Port Mode—This setting specifies the operating mode for
LPT1. Usually, the default setting works for all applications. However,
if a parallel port device requires a nondefault setting, select it here. The
default is value is Normal (full IEEE 1284 capabilities).
• Parallel Port IRQ—This setting specifies the interrupt request level
(IRQ) for LPT1, the parallel port. The default value is IRQ7.
USB Configuration Submenu
Use this submenu to apply alternate configurations to the USB ports.
Normally, you do not need to modify these settings, as the factory default
settings provide the most compatible and optimal configuration.
• Legacy USB Support—This setting specifies whether or not legacy
USB support is enabled. Legacy USB support refers to the ability to
use a USB keyboard and mouse during system boot or in a legacy
operating system such as DOS. The default is Enabled.
Note Certain real-time applications may require you to disable this setting to reduce loop
time jitter. When the controller is configured to boot LabVIEW RT, legacy USB support is
automatically disabled.
