Operating the BNC-2115 in Single-Ended Mode
You can increase the number of analog input channels by configuring
the DAQ device analog input to operate in either referenced single-ended
(RSE) mode, or nonreferenced single-ended (NRSE) mode. In either of
these modes, each BNC coaxial cable carries two single-ended channels,
instead of one differential channel.
To configure the analog input using Traditional NI-DAQ, open
Measurement & Automation Explorer (MAX), open
Devices and
Interfaces»Traditional NI-DAQ Devices
, then right-click the icon for
your device. Select
Properties
from the menu, then click the
AI
tab and
change the analog input (AI) mode to RSE or NRSE.
To configure input terminals using NI-DAQmx, use the DAQ Assistant or
the NI-DAQmx API. For more information, refer to the
DAQ Assistant Help
and the
Measurement and Automation Explorer Help for NI-DAQmx
