Introduction
This chapter describes the NI 781 x R/783 x R/784 x R/785 x R, the concept of
the Reconfigurable I/O (RIO) device, optional software and equipment for
using the NI 78
xx R, and safety information about the NI 78 xx R.
About the Reconfigurable I/O Device
Table 1-1 lists an overview of the NI 78 xx R R Series Intelligent DAQ RIO
devices.
A user-reconfigurable FPGA (Field-Programmable Gate Array) controls
the digital I/O lines on the NI 781
x R, and the digital and analog I/O lines
on the NI 783 x R/784 x R/785 x R. 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
