GETTING STARTED GUIDE

NI 9860

2-Port, C Series Vehicle Multiprotocol Interface

Module

This document explains how to connect to the NI 9860.

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 9860. 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 9860 only as described in this document.

Hot Surface This icon denotes that the component

may be hot. Touching this component may result in

bodily injury.

Caution Do not operate the NI 9860 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

2| ni.com | NI 9860 Getting Started Guide

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

repair.

Safety Guidelines for Hazardous Locations

The NI 9860 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 9860 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.

Special Conditions for Hazardous Locations Use in

Europe and Internationally

The NI 9860 has been evaluated as Ex nA IIC T4 Gc equipment

under DEMKO Certificate No. 12 ATEX 1202658X and is

IECEx 14.0089X certified. Each NI 9860 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 9860

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.

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 9860

The NI 9860 has two ports for connecting to NI-XNET CAN/LIN

Transceiver Cables (required to connect to the CAN/LIN bus)

and a two-position connector for use with an external power

supply.

For more information about transceiver cables, refer to the

NI-XNET CAN/LIN Transceiver Cables page on ni.com.

The NI 9860 requires an external power supply of +9 to +30 V to

power the transceiver cables. Supply power to the NI 9860 VSUP

connector on the module front panel using the supplied power

cable. The exposed lead wires at the end of the power cable are

routed as follows: black wire—COM, red wire—VSUP. The

power cable lead wires may be daisy-chained to the controller

power port when the controller supply voltage is in the

appropriate range.

Note Power on VSUP is required for transceiver cable

operation.

Note When using more than four transceiver cables

with your CompactRIO chassis, refer to the NI-XNET

CAN/LIN Transceiver Cables page on ni.com for

mounting guidelines to limit the thermal impact to your

CompactRIO system.

The following figure shows the NI 9860 with Port 1 connected to

an NI-XNET CAN HS/FD Transceiver Cable and the

two-position connector connected to the power cable. The breaks

in the cables represent additional cable length.

NI 9860 Hardware Overview

The NI 9860 is a two-port C-Series module based on the XNET

architecture. Users can choose the physical bus protocol by

plugging in the corresponding transceiver cable. The NI 9860
