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
NI 60xx (E Series), NI 62xx (M Series), NI 63xx (X Series), NI ELVIS II, NI PCI-6010, NI USB-6001, NI USB-6002, NI USB-6003, NI USB-6008, NI USB-6009, and NI TC01 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 0-7, 16-23, and 32-39 are differential. Channels 8-15, 24-31, and 40-47 are referenced-single ended. Referenced single-ended
myDAQ Differential for the analog input channels, referenced single-ended for the audio input channels. Referenced single-ended
NI ELVIS II+ Referenced single-ended for scopeCh0 and scopeCh1. For other analog input channels: differential for channels 0-7, referenced single-ended for channels 8-15. Referenced single-ended

For instance, channels 0-7, 16-23, and 32-39 are differential. Channels 8-15, 24-31, and 40-47 are referenced-single ended. N/A
