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 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.
