Note

If you do not have the current version of NI-DAQmx or one of the documents, you 

can download them from the National Instruments Web site at 

ni.com

 or contact an NI 

sales representative. Software scaling of measurements is not supported on the Macintosh 
operating system. Refer to the

 section for information about software 

scaling.

Device Specific Information

Note

For general SCC module installation and signal connection information, and 

information about the SC-2345 or SC-2350 carrier, refer to the 

SCC Quick Start Guide

Installing the Module

Caution

Refer to the 

Read Me First: Safety and Radio-Frequency Interference

 document 

before removing equipment covers or connecting/disconnecting any signal wires.

You can plug the SCC-RTD01 into any AI socket on the SCC. 
The SCC-RTD01 can function as a single-stage module or as the first stage 
of a dual-stage signal conditioning configuration. The socket you choose 
determines which E/M Series DAQ device channels receive the 
SCC-RTD01 signals, as explained in the 

SCC Quick Start Guide

.

For single-stage input conditioning, plug the SCC-RTD01 into any socket 
J(

X

+

1), where 

X

 is 0 to 7, and connect the input signals to the module as 

described in the 

SCC Quick Start Guide
