Default Input/Output Terminal Configurations
If you do not explicitly specify the input or output terminal configuration when you create a channel, NI-DAQmx automatically determines the default terminal configuration at run time. The following table lists the default terminal configurations for devices.
| Device | Default Input Terminal Configuration | Default Output Terminal Configuration |
|---|---|---|
| AO Series | N/A | Referenced single-ended |
| DSA | Pseudodifferential | Differential |
| E and M Series, NI PCI-6010, NI 9205, and NI 9206 | For devices with eight channels: differential for the first four channels, referenced single-ended for the next four channels. For devices with 16 channels or more: differential for eight channels followed by referenced single-ended for eight channels. For instance, channels 1-7, 16-23, and 32-39 are differential. Channels 8-15, 24-31, and 40-47 are referenced-single ended. | Referenced single-ended |
| NI PXI-6132, NI PXI-6133, NI PXI-6143 | Differential | N/A |
| NI PCI-6110, NI PCI-6111, NI 6115, NI 6120 | Pseudodifferential | Referenced single-ended |
| NI PXI-42XX | Differential | N/A |
| SCC | Non-referenced single-ended | Referenced single-ended |
| SCXI | Differential | Differential |
| NI 9201, NI USB-9201, NI 9203, NI 9217, NI 9221, NI USB-92211 | Referenced single-ended | N/A |
| NI 9211, NI USB-9211, NI 9215, NI USB-9215, NI 9219, NI USB-9219, NI 9225, NI 9229, NI USB-9229, NI 9235, NI 9236, NI 9237, NI USB-9237, NI 9239, NI USB-92391 | Differential | N/A |
| NI 9233, NI USB-9233, NI 9234, NI USB-9234 | Pseudodifferential | N/A |
| NI 9263, NI USB-9263, NI 9264, and NI 9265 | N/A | Referenced single-ended |
