nnnn

Overview

nnnn

The NI 9402 Measurement System includes four bi-directional DIO channels and four counter/timers, communicating with a host PC

nnnn

over USB, Ethernet or 802.11 Wi-Fi.

nnnn

Measurement Bundle Overview

nnnn

The hardware for an NI CompactDAQ single measurement bundle consists of a USB, Ethernet, or 802.11 W-Fi chassis and one of

nnnn

the over 50 NI C Series measurement-specific modules. These small rugged bundles are ideal for portable or distributed

nnnn

measurements.

nnnn

Chassis

nnnn

The chassis controls the timing for the module and handles communication with the PC over the USB, Ethernet, or 802.11 W-Fi bus.

nnnn

Additionally, all NI CompactDAQ chassis include four counter/timers that you can access through a digital I/O module like the NI 9402.

nnnn

Module

nnnn

The NI 9402 is a 4-channel, 55 ns bidirectional digital input module for any NI CompactDAQ or CompactRIO chassis. You can

nnnn

configure the direction of the digital lines on the NI 9402 for input or output by bit. Thus, you can program this module for three

nnnn

configurations - four digital inputs, four digital outputs, or two digital inputs and two digital outputs. With reconfigurable I/O (RIO)

nnnn

technology (CompactRIO only), you can use the NI LabVIEW FPGA Module to program the NI 9402 for implementing custom,

nnnn

high-speed counter/timers, digital communication protocols, pulse generation, and much more. Each channel is compatible with 5

nnnn

V/TTL signals and features 1,000 Vrms transient isolation between the I/O channels and the backplane.
