GETTING STARTED GUIDE

NI 9881

1-Port CANopen Module

This document explains how to connect to the NI 9881.

The NI 9881 module requires the latest NI-CANopen software to

be installed. The latest version of the NI-CANopen software is at

ni.com/downloads.

Note Before you begin, complete the software and

hardware installation procedures in your chassis

documentation.

Note The guidelines in this document are specific to

the NI 9881. The other components in the system might

not meet the same safety ratings. Refer to the

documentation for each component in the system to

determine the safety and EMC ratings for the entire

system.

Safety Guidelines

Operate the NI 9881 only as described in this document.

Caution Do not operate the NI 9881 in a manner not

specified in this document. Product misuse can result in

a hazard. You can compromise the safety protection

built into the product if the product is damaged in any

way. If the product is damaged, return it to NI for

repair.

Safety Guidelines for Hazardous Locations

The NI 9881 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. Follow these guidelines if you are installing the

NI 9881 in a potentially explosive environment. Not following

these guidelines may result in serious injury or death.

Caution Do not disconnect I/O-side wires or

connectors unless power has been switched off or the

area is known to be nonhazardous.

Caution Do not remove modules unless power has

been switched off or the area is known to be

nonhazardous.

Caution Substitution of components may impair

suitability for Class I, Division 2.

Caution For Division 2 and Zone 2 applications,

install the system in an enclosure rated to at least IP54

as defined by IEC/EN 60079-15.

NI 9881 Getting Started Guide | © National Instruments | 3

Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

Caution For Division 2 and Zone 2 applications,

install a protection device between the external power

supply and the Vsup pin. The device must prevent the

Vsup-to-COM voltage from exceeding 50 V if there is

a transient overvoltage condition.

Caution For Zone 2 applications, install a protection

device between the CAN signals and the NI 9881 CAN

pins. The device must prevent the CAN Port-to-COM

voltage from exceeding 55 V if there is a transient

overvoltage condition.

Special Conditions for Hazardous Locations Use in

Europe and Internationally

The NI 9881 has been evaluated as Ex nA IIC T4 Gc equipment

under DEMKO Certificate No. 07 ATEX 0626664X and is

IECEx UL 14.0089X certified. Each NI 9881 is marked II 3G

and is suitable for use in Zone 2 hazardous locations, in ambient

temperatures of -40 °C ≤ Ta ≤ 70 °C. If you are using the NI 9881

in Gas Group IIC hazardous locations, you must use the device in

an NI chassis that has been evaluated as Ex nC IIC T4, Ex IIC

T4, Ex nA IIC T4, or Ex nL IIC T4 equipment.

Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

Caution You must make sure that transient

disturbances do not exceed 140% of the rated voltage.

Caution The system shall only be used in an area of

not more than Pollution Degree 2, as defined in

IEC 60664-1.

Caution The system shall be mounted in an

ATEX/IECEx-certified enclosure with a minimum

ingress protection rating of at least IP54 as defined in

IEC/EN 60079-15.

Caution The enclosure must have a door or cover

accessible only by the use of a tool.

Wiring the NI 9881

The NI 9881 has one 9-pin male D-Sub connector that provides

connections to a CAN bus. The NI 9881 has pins for CAN_H and

CAN_L, to which you connect the CAN bus signals. Connect

these signals using twisted-pair cable.

The port has two common pins (COM) that are internally

connected to the module’s isolated reference and serve as the

NI 9881 Getting Started Guide | © National Instruments | 5

Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

reference ground for CAN_H and CAN_L. You can connect the

CAN bus reference ground (sometimes referred to as CAN_V-) to

one or both COM pins. The port also has an optional shield pin,

SHLD, that you can connect to a shielded CAN cable.

Connecting SHLD may improve signal integrity and EMC

performance in a noisy environment.

Caution You must use a UL listed ITE power supply

marked LPS with the NI 9881.

The NI 9881 requires an external power supply of +9 to +30 V to

operate. Supply power to the NI 9881 VSUP pin.

Note Power on VSUP is required for CANopen

operation.

The NI 9881 pinout is listed in Table 1.

The NI 9881 features software-selectable bus termination for

High-Speed CAN transceivers. On the NI 9881, you can enable

120 Ω termination resistors between CAN_H and CAN_L

through an API call. Table 3 lists recommended termination

resistor values.

CAN Bus Topology and Termination

A CAN bus consists of two or more CAN nodes cabled together.

The CAN_H and CAN_L pins of each node are connected to the

NI 9881 Getting Started Guide | © National Instruments | 7

Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

main CAN bus cable through a short connection known as a

“stub.” The pair of signal wires, CAN_H and CAN_L, constitutes

a transmission line. If the transmission line is not terminated,

each signal change on the bus causes reflections that may cause

communication errors. Because the CAN bus is bidirectional,

both ends of the cable must be terminated. However, this

requirement does not mean that every node on the bus should

have a termination resistor; only the two nodes at the far end of

the cable should have termination resistors.

Figure 1 shows a simplified diagram of a CAN bus with multiple

CAN nodes and proper termination resistor (Rt) locations.

Connecting a CAN Bus to the NI 9881

You can connect the NI 9881 port to any location on a CAN bus.

Figure 2 shows one example of connecting the NI 9881 directly

to one CAN node.
