Getting Started with the NI 7831R

Figure 2 shows the pin assignments for the I/O connectors on the
NI 7831R. The DIO connector pin assignment applies to both DIO
connectors on the NI 7831R.

Figure 2.

NI 7831R I/O Connector Pin Assignments

Caution

Connections that exceed any of the maximum ratings of input or output signals

on the NI 7831R can damage the NI 7831R and the computer. NI is

not

liable for any

damage resulting from such signal connections. Refer to the

NI 7831R User Manual

for

the maximum input ratings for each signal.

For detailed information about connecting I/O signals, refer to the

NI 7831R User Manual
