Introduction
This chapter describes the NI 781xR/783xR/784xR/785xR, the concept of
the Reconfigurable I/O (RIO) device, optional software and equipment for
using the NI 78xxR, and safety information about the NI 78xxR.
About the Reconfigurable I/O Device
Table 1-1 lists an overview of the NI 78xxR R Series Intelligent DAQ RIO
devices.
A user-reconfigurable FPGA (Field-Programmable Gate Array) controls
the digital I/O lines on the NI 781xR, and the digital and analog I/O lines
on the NI 783xR/784xR/785xR. The FPGA on the R Series device allows
you to define the functionality and timing of the device. You can change the
functionality of the FPGA on the R Series device in LabVIEW using the
LabVIEW FPGA Module to create and download a custom virtual
instrument (VI) to the FPGA. Using the FPGA Module, you can
graphically design the timing and functionality of the R Series device. If
you only have LabVIEW but not the FPGA Module, you cannot create new
