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 and NI PCI-6010 | Differential for the first eight channels, referenced single-ended for the next eight channels. For devices with more than 16 channels, the next eight channels (16-23) are differential followed by eight channels (24-31) of referenced single-ended and so on. | 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 USB-9201, NI USB-92211 | Reference single-ended | N/A |
NI USB-9211, NI USB-9215, NI USB-92331 | Differential | N/A |
1All listed devices have a fixed terminal configuration. |
