This file contains information about the NI-CAN™ driver software for Windows 7/Vista/XP and LabVIEW™ Real-Time (ETS). Information in this file is organized in the following sections:
The CAN Hardware and NI-CAN Software for Windows Installation Guide included with the NI-CAN CD includes instructions for installing National Instruments CAN hardware and software.
The NI-CAN Hardware and Software Manual is the primary document for NI CAN products. This manual includes an introduction to CAN, specifications for hardware, information about how to get started with application development, and a complete reference for all NI-CAN functions.
The NI-CAN Hardware and Software Manual is in Adobe Acrobat Portable Document Format (PDF). You can download the Acrobat Reader for free at: www.adobe.com.
Open the manual from Start»All Programs»National Instruments»NI-CAN.
Links to the NI-CAN Hardware and Software Manual are in the online help for each NI-CAN function within the National Instruments LabVIEW and LabWindows™/CVI™ development environments.
Online help for the NI-CAN features within Measurement & Automation Explorer (MAX) is in the MAX Help Topics menu. The MAX Help Topics menu for NI-CAN also includes a link to the NI-CAN Hardware and Software Manual.
You must install and run this version of the NI-CAN software on the following operating systems:
Note: National Instruments recommends using Service Pack 2 or newer when using the USB-847x interfaces in hyperthread or multicore CPU environments on Microsoft Windows XP.
The NI-CAN installer does not support Windows NT/Me/2000/98/95.
This version of the NI-CAN software supports the following National Instruments hardware products on Windows and LabVIEW RT:
This version of the NI-CAN software supports the following National Instruments hardware products on Windows:
Note: PCMCIA-CAN and PCMCIA-CAN/2 interfaces are not supported on the 64-bit version of Windows Vista.
Several National Instruments Series 1 CAN hardware products are not supported in this version of NI-CAN. Install NI-CAN version 2.2 for support of the following hardware products (available on ni.com):
Install NI-CAN version 2.1.3 for support of the following AT (ISA) hardware products (available on ni.com):

This version of the NI-CAN software supports the following development environments:
Before installing the NI-CAN software, log on as Administrator or as a user with Administrator privileges. The NI-CAN software setup program must have Administrator privileges because the program modifies the configuration registry of your system. Complete the following steps to install the NI-CAN software.
You can control programmatically which features in the NI-CAN distribution to enable or disable for installation. You therefore can install a subset of the NI-CAN distribution silently. Refer to the template_spec.txt file in the specfiles directory on the NI-CAN CD for more information about installing NI-CAN silently and selecting which features to install automatically.

As the Traditional NI-DAQ driver software is not supported on Windows Vista or Windows 7, the following CAN/DAQ synchronization VIs are not available on Windows Vista or Windows 7:
NI-CAN provides support for CANdb network files created using the Vector CANdb or CANdb++ editor. You can use the information from the CANdb file in Measurement & Automation Explorer (MAX) or with the NI-CAN Channel API. For more information, refer to the Using the Channel API chapter in the NI-CAN Hardware and Software Manual.
NI-CAN supports CANdb network files created using the CAN module of Vector products. NI-CAN does not provide complete support of CANdb files created using modules for higher-layer CAN protocols, such as J1939, ISO11783, or NMEA2000. To view the set of features supported for these modules, import the CANdb file into MAX. NI-CAN displays an error dialog for any unsupported object and displays those objects with a red mark. For example, the J1939 protocol for multiframe messages (greater than 8 bytes) is not supported in the current version of NI-CAN.
NI-CAN 2.4 (or newer) includes several new Frame API attributes. If you have a LabVIEW VI written for an earlier version of NI-CAN, upgrading to NI-CAN 2.4 (or newer) will not automatically update constants or controls for the AttrId input. To use the new attributes, replace your older constants and controls using the AttrId input of the updated NI-CAN VIs.
If you do not want to use new Frame API attributes, you can continue to use the older constants and controls for compatibility.
This issue does not apply to the Channel API for LabVIEW. Because the Get/Set Property functions are provided as polymorphic VIs, they are automatically updated.
