GETTING STARTED GUIDE NI 9853 2-Port, High-Speed CAN Module Français Deutsch 日本語 한국어 简体中文 ni.com/manuals This document explains how to connect to the NI 9853.
The NI 9853 module requires the latest NI 985x software to be ni.com/ installed. The latest version of the NI 985x software is at downloads. Before you begin, complete the software and Note hardware installation procedures in your chassis documentation.
Safety Guidelines for Hazardous Locations The NI 9853 is suitable for use in Class I, Division 2, Groups A, B, C, D, T4 hazardous locations; Class I, Zone 2, AEx nA IIC T4 and Ex nA IIC T4 hazardous locations; and nonhazardous locations only.
Special Conditions for Hazardous Locations Use in Europe and Internationally The NI 9853 has been evaluated as Ex nA IIC T4 Gc equipment under DEMKO Certificate No. 03 ATEX 0324020X and is IECEx 14.0089X certified. Each NI 9853 is marked...
Wiring the NI 9853 The NI 9853 has two 9-pin male D-Sub connectors that provide connections to a CAN bus. Each port on the NI 9853 has pins for CAN_H and CAN_L, to which you connect the CAN bus signals.
