Device Routing in MAX
To find the device routing table for your device, launch MAX and select Devices and Interfaces. Click a device to open a tabbed window in the middle pane. Click the Device Routes tab at the bottom of the pane to display the device routing table.
Each cell in the table is an index with the valid source and destination terminal for the device. These are the same terminal names you can find in the Terminal Name I/O control in LabVIEW.
If a route is possible between a source and destination terminal, the intersecting cell is colored green or yellow. A green cell indicates the route can be made without consuming any important resource of your device. A yellow cell indicates that although the route is possible, something important must be consumed to create the route. Placing the cursor over a yellow square reveals the resource used in the subsystem used indicator. Usually, the sacrificed resource is a counter.
When you display the device routing table for a cDAQ chassis or a C Series device, the table contains all of the terminals for the chassis and all devices installed in the chassis.

- AI Sample Clock Signal
Use the AI Sample Clock (ai/SampleClock) signal to initiate a set of measurements. The PXIe-6368 samples the AI signals of every channel in the task once for every AI Sample Clock. A measurement acquisition consists of one or more samples.
- AI Start Trigger Signal
Use the AI Start Trigger (ai/StartTrigger) signal to begin a measurement acquisition. A measurement acquisition consists of one or more samples. If you do not use triggers, begin a measurement with a software command.
- AI Reference Trigger Signal
Use AI Reference Trigger (ai/ReferenceTrigger) signal to stop a measurement acquisition. To use a reference trigger, specify a buffer of finite size and a number of pretrigger samples (samples that occur before the reference trigger). The number of posttrigger samples (samples that occur after the reference trigger) desired is the buffer size minus the number of pretrigger samples.
- AI Pause Trigger Signal
- AO Start Trigger Signal
Use the AO Start Trigger (ao/StartTrigger) signal to initiate a waveform generation. If you do not use triggers, you can begin a generation with a software command.
- AO Sample Clock Signal
Use the AO Sample Clock (ao/SampleClock) signal to initiate AO samples.
- AO Pause Trigger Signal
Use the AO Pause Trigger (ao/PauseTrigger) signal to mask off samples in a DAQ sequence. When AO Pause Trigger is active, no samples occur. AO Pause Trigger does not stop a sample that is in progress. The pause does not take effect until the beginning of the next sample.
- DI Sample Clock Signal
The PXIe-6368 uses the DI Sample Clock (di/SampleClock) signal to sample the Port 0 terminals and store the result in the DI waveform acquisition FIFO.
- DI Start Trigger Signal
Use the DI Start Trigger (di/StartTrigger) signal to begin a measurement acquisition. A measurement acquisition consists of one or more samples. If you do not use triggers, begin a measurement with a software command. Once the acquisition begins, configure the acquisition to stop:
- DI Reference Trigger Signal
Use the DI Reference Trigger (di/ReferenceTrigger) signal to stop a measurement acquisition. To use a reference trigger, specify a buffer of finite size and a number of pretrigger samples (samples that occur before the reference trigger). The number of posttrigger samples (samples that occur after the reference trigger) desired is the buffer size minus the number of pretrigger samples.
- DI Pause Trigger Signal
- DO Sample Clock Signal
The PXIe-6368 uses the DO Sample Clock (do/SampleClock) signal to updates the DO terminals with the next sample from the DO waveform generation FIFO.
- DO Start Trigger Signal
Use the DO Start Trigger (do/StartTrigger) signal to initiate a waveform generation. If you do not use triggers, you can begin a generation with a software command.
- DO Pause Trigger Signal
Use the DO Pause Trigger (do/PauseTrigger) signal to mask off samples in a DAQ sequence. When DO Pause Trigger is active, no samples occur.
- Using an Internal Source
To use Counter n Sample Clock with an internal source, specify the signal source and the polarity of the signal.
