additional hazards, do not install unauthorized parts or modify the device. Return the
device to National Instruments for service and repair to ensure that its safety features
are not compromised.
You must insulate all of your signal connections to the highest voltage with which the
TB-2705 can come in contact.
Connections, including power signals to ground and vice versa, that exceed any of the
maximum signal ratings on the terminal block can create a shock or fire hazard, or can
damage any or all of the boards connected to the host computer, and the terminal block.
National Instruments is not liable for any damages or injuries resulting from incorrect

Analog Input Ground—These
terminals are the reference point for
single-ended measurements in RSE
configuration and the bias current
return point for differential
measurements. All three ground
references—AIGND, AOGND, and
DGND—are connected together on
your E Series device.
Input
Analog Input Channels 0 through
15—You can configure each channel
pair, ACH<i, i+8> (i = 0..7), as either
one differential input or two
single-ended inputs.
