NI-9866 Getting Started

Overview

This document explains how to connect to the NI-9866.

Note Before you begin, read the NI-9866 Safety, Environmental, and

Regulatory Information document on ni.com/manuals and complete the

soware and hardware installation procedures in your chassis

documentation.

Note The guidelines in this document are specific to the NI-9866. 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

Caution Observe all instructions and cautions in the user documentation.

Using the product in a manner not specified can damage the product and

compromise the built-in safety protection.

Attention Suivez toutes les instructions et respectez toutes les mises

en garde de la documentation d'utilisation. L'utilisation du produit de

toute autre façon que celle spécifiée risque de l'endommager et de

compromettre la protection de sécurité intégrée.

Safety Guidelines for Hazardous Locations

The NI-9866 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 Gc and Ex nA IIC T4 hazardous locations; and

nonhazardous locations only. Follow these guidelines if you are installing the

NI-9866 in a potentially explosive environment. Not following these guidelines may

result in serious injury or death.

NI-9866 Getting Started

Caution Do not disconnect I/O-side wires or connectors unless power has

been switched o or the area is known to be nonhazardous.

Caution Do not remove modules unless power has been switched o or

the area is known to be nonhazardous.

Caution Substitution of components may impair suitability for Class I,

Division 2, or Zone 2.

Caution The system must be installed in an enclosure certified for the

intended hazardous (classified) location, having a tool secured cover/door,

where a minimum protection of at least IP54 is provided.

Special Conditions for Hazardous Locations Use in Europe and

Internationally

The NI-9866 has been evaluated as Ex nA IIC T4 Gc equipment under

DEMKO 07ATEX 0626664X and is IECEx UL 14.0089X certified. Each NI-9866 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-9866 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 Transient protection shall be provided that is set at a level not

exceeding 140% of the peak rated voltage value of 85 V at the supply

terminals to the equipment.

Caution The system shall only be used in an area of not more than

Pollution Degree 2, as defined in IEC/EN 60664-1.

NI-9866 Getting Started

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 9866

The NI-9866 has one 9-pin male D-Sub connector that provides connections to a LIN

bus.

The port has two common pins (COM) that are internally connected to the module’s

isolated reference and serve as the reference ground for LIN signal. You can connect

the LIN bus reference ground to one or both COM pins. The port also has an optional

shield pin, SHLD, that you can connect to a shielded LIN 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-9866.

The NI-9866 requires an external power supply of +8 to +18 V to operate. Supply

power to the NI-9866 VSUP pin from the LIN bus.

Note Power on VSUP is required for LIN operation.

The NI-9866 pinout is listed in Table 1.

Cabling Requirements for the NI 9866

This section deals with cabling specifications, termination resistors, cable lengths,

and the number of LIN nodes that can exist in a system.

Cable Specifications

LIN cables should meet the physical medium requirement of a bus RC time constant

of 5 µs. For detailed formulas for calculating this value, refer to the Line

Characteristics section of the LIN specification. Belden cable (3084A) and other

unterminated CAN/Serial quality cables meet these requirements and should be

suitable for most applications.

Cable Lengths

The maximum allowable cable length is 40 m, per the LIN specification.

Number of LIN Devices

The maximum number of devices on a LIN bus is 16, per the LIN specification.

Termination Resistors

LIN cables require no termination, as nodes are terminated at the transceiver. Slave

nodes typically are pulled up from the LIN bus to VBat with a 30 kΩ resistance and a

serial diode. This termination usually is integrated into the transceiver package. The

master node requires a 1 kΩ resistor and serial diode between the LIN bus and VBat.

On NI-XNET LIN products, master termination is soware selectable; you can enable

it in the API with the NI-XNET Session Interface:LIN:Termination property.

NI 9866 Hardware Overview

The NI-9866 has one full-featured LIN port that is isolated from the other modules in

the system. The port has a LIN controller that is fully compliant with the LIN

1.3/2.0/2.1/2.2 Specification. The port also has an NXP TJA1028 LIN transceiver that

is fully compatible with the LIN 1.3/2.0/2.1/2.2 and SAE J2602 standard and supports

baud rates up to 20 kbps.
