Tip Strip: Selects operating mode for DI Driver module
Detail: Operating mode applied to the associated DI Driver module.
Each DI Driver module can be independently assigned a mode of operation which will apply to all channels of the
associated DI Driver module. The DIX_Mode refers to the mode of sending injection commands to the channels of
the associated module. It is still necessary to configure the current and voltage drive profile via this DIX_Driver Setup
window.
Direct Mode: The DI Driver module channels are commanded directly by external digital inputs of the NI 9411
modules. The digital input which commands each channel can be configured via the Digital Input Setup window. The
digital input level which commands the DI Driver channel ON is configured via the Invert buttons of the Digital Input
Setup window. The duration of the injection command is determined by the direct duration of the digital input. The
maximum duration allowed is 5 msec. If longer durations are required, consult with your National Instruments sales
engineer or support team.
Calibration Mode: Calibration mode is for the purpose doing injector flow calibrations. Calibration mode is
configured via the Calibration Mode Setup window for a specified number of injection events, command duration
and command period. Only one channel of each module may be enabled for Calibration mode . If more than one
channel is enabled, then commands will not be delivered.
Triggered Multi-Pulse (TMP) Mode: The DI Driver module channels are commanded by a specified sequence
of pulses and triggered by an external digital rising or falling edge to the assigned digital input channel. The pulse
sequence is configured via the DI-TMP tab of the Pulse Generation Setup window. The external trigger channel is
assigned via the Digital Input Setup window.
Engine Position Tracking (EPT) Mode:
The DI Driver module channels are commanded by a specified sequence
of pulses and triggered by crankshaft angle events for each pulse, with respect to an assigned Top Dead Center
(TDC) reference value. The pulse sequence is configured via the DI-EPT tab of the Pulse Generation Setup window.
The TDC reference value is configured via the TDC Channel Mapping tab of the Engine Position Tracking Setup
window. Engine position tracking parameters are configured via the EPT tab of the Engine Position Tracking Setup
window for a variety of crank and cam signal patterns.
DIX_PowerSupplyEnable
Tip Strip: Enables internal boost power supply DI Driver Setup window
Detail: When ON , the module internal boost power supply is enabled and will maintain the working voltage specified
by DIX_HVTarget
. When
OFF , the module internal boost power supply is disabled. The actual boost voltage is
displayed in the Internal High Voltage indicator within this window. For more information on the module internal boost
power supply, please see Powering the System .
DIX_InjectionEnable
Tip Strip: Enables all channels of module
