Introduction
CAN interfacing is accomplished using the Intel 82527 CAN controller
chip. The PCI-CAN physical layer fully conforms to the ISO 11898
physical layer specification for CAN and is optically isolated to 500 V.
PCI-CAN boards are available with two physical connector types: DB-9
D-Sub and Combicon-style pluggable screw terminals. PCMCIA-CAN
cables include both a DB-9 D-Sub and a Combicon-style pluggable screw
terminal. The CAN physical layer on PCI-CAN cards can be powered
either internally (from the card) or externally (from the bus cable power).
The power source for the CAN physical layer for each port is configured
with a jumper. There are two cables available for the PCMCIA-CAN cards.
In one cable the CAN physical layer is powered internally (from the card).
In the other cable the CAN physical layer is powered externally (from the
bus cable power). The CAN hardware supports a wide variety of transfer
rates up to 1 Mb/s.
All of the CAN hardware uses the Intel 386EX embedded processor to
implement time-critical features provided by the NI-CAN software. The
CAN hardware communicates with the NI-CAN driver through on-board
shared memory and an interrupt.
NI-CAN Software Overview
The NI-CAN software includes a native, 32-bit multitasking Windows NT
kernel driver.
The NI-CAN software for Windows NT supports the concurrent use of
multiple types of CAN hardware. For example, you can communicate with
CAN devices through both a PCI-CAN and PCI-CAN/2 in the same system
at the same time. The NI-CAN software is fully integrated into the
Windows NT operating system. It is configurable through the Windows NT
Control Panel and uninstallable through the Add/Remove Programs applet
of the Control Panel.
The NI-CAN software, along with the CAN hardware, transforms your
computer into a CAN interface with complete communications and bus
management capability. The NI-CAN software includes the following
components:

Optional Programming Tools
Your kit includes the NI-CAN software for Windows NT. In addition,
you can order the LabWindows/CVI or LabVIEW software from National
Instruments.
LabWindows/CVI is an interactive ANSI C development environment for
building test and measurement and instrument control systems. It includes
interactive code-generation tools and a graphical editor for building custom
user interfaces. It also includes built-in libraries for IEEE 488.2, VXI,
RS-232 control, and plug-in data acquisition. When you order
LabWindows/CVI, you also get hundreds of complete instrument drivers,
which are modular, source-code programs that handle the communication
with your instrument so that you do not have to learn the programming
details.
LabVIEW is a complete programming environment that departs from the
sequential nature of traditional programming languages and features a
graphical programming environment. It includes all the tools needed for
instrument control, data acquisition, analysis, and presentation. LabVIEW
also includes an extensive instrument driver library.

Begin to Use the
NI-CAN Software
This chapter helps you get started with the NI-CAN software for
Windows NT.
Using the NI-CAN Software
The functions provided by the NI-CAN software are similar to those
provided by many other device drivers. For example, NI-CAN has open,
close, read, and write functions. NI-CAN provides two different levels of
access to a CAN network: the CAN Network Interface Object and CAN
Objects. Both forms of access support timestamping of incoming data, as
well as various forms of queuing.
The CAN Network Interface Object provides low-level access to a CAN
network. Each CAN Network Interface Object maps to a specific CAN
port, with no limitation on the maximum number of ports or cards you can
use (for example, two PCI-CAN/2 interfaces would provide CAN0through
CAN3). You can use this object to transmit and receive entire CAN frames.
For example, to transmit a CAN frame, you would specify the outgoing
arbitration ID, frame type (data or remote), data length, and data.
The CAN Objects provide higher level access to a CAN network. Each
CAN Object maps to a specific data item (arbitration ID), and you can use
multiple CAN Objects for a given port. When configuring a CAN Object
for use, you specify the arbitration ID, direction of data transfer, data
length, and how you want the data to be accessed (such as periodically).
For example, you could configure a CAN Object to transmit an outgoing
data frame for a specific arbitration ID every 100 ms. After opening this
CAN Object, you use the write function to provide data to transmit, and the
NI-CAN embedded firmware handles all periodic timing.
For detailed information about the NI-CAN software and functions, refer
to the NI-CAN User Manual for Windows 95 and Windows NT and the
NI-CAN Programmer Reference Manual for Win32.

Begin to Use the NI-CAN Software
General Programming Considerations
As you begin developing your Win32 NI-CAN application, remember the
following points:
•
•
•
For your LabVIEW application, you must use the NI-CAN LabVIEW
functions in nican.llb.
For your C/C++ application, you must include the NI-CAN header file,
nican.h, in your source code.
The NI-CAN software is accessed through the 32-bit DLL,
nican.dll, either by linking with one of the language interfaces
provided with the NI-CAN software, or by using direct DLL entry
from other programming environments.
•
Several sample CAN applications are included with the NI-CAN
software. Use these as a guide for your own application development.
For information about developing your application, refer to the NI-CAN
User Manual for Windows 95 and Windows NT. For detailed information
about NI-CAN functions and objects, refer to the NI-CAN Programmer
Reference Manual for Win32.

Uninstall the Hardware
and Software
This appendix describes how to uninstall the CAN hardware and the
NI-CAN software from Windows NT.
Uninstalling the CAN Hardware from Windows NT
Because the current version of Windows NT does not maintain hardware
information for the CAN interfaces, you just need to physically remove the
CAN interfaces from your computer. To do so, shut down Windows NT,
power off your computer, and physically remove the CAN interfaces.
Uninstalling the NI-CAN Software from Windows NT
Note
The following instructions apply to Windows NT 4.0 only. If you are using
Windows NT 3.51, refer to the readme.txtfile in your NI-CAN directory
for information on how to uninstall the NI-CAN software.
Before uninstalling the NI-CAN software, you should remove all CAN
interface hardware from your computer, as explained in the previous
section.
Complete the following steps to remove the NI-CAN software:
1. Select the Add/Remove Programs icon under Start»Settings»

Cabling Requirements
This appendix describes the cabling requirements for CAN interfaces.
Cables should be constructed to meet these requirements, as well as the
requirements of the other CAN or DeviceNet devices in the network.
Connector Pinouts
Depending on the type of CAN interface you are installing, the CAN
hardware either has DB-9 D-Sub connectors(s), or Combicon-style
pluggable screw terminal connector(s).
The 9-pin D-Sub follows the pinout recommended by CiA DS 102.

Power Supply Information for the CAN Ports
For the PCI-CAN and PCI-CAN/2, the power source for the CAN physical
layer is configured with a jumper. For the PCI-CAN and port one of the
PCI-CAN/2, power is configured with jumper J6. For port two of the
PCI-CAN/2, power is configured with jumper J5. The location of these
jumpers is shown in Figure B-4.

Figure B-4. PCI-CAN/2 Power Source Jumpers
Connecting pins 1 and 2 of a jumper configures the CAN physical layer to
be powered externally (from the bus cable power). In this configuration, the
power must be supplied on the V+ and V– pins on the port connector.
Connecting pins 2 and 3 of a jumper configures the CAN physical layer to
be powered internally (from the card). In this configuration, the V– signal
serves as the reference ground for the isolated signals.

The CAN physical layer is still isolated regardless of the power source
chosen.
The PCMCIA-CAN and PCMCIA-CAN/2 are available with two types of
cable. The DeviceNet (bus powered) cable requires that the CAN physical
layer be powered from the bus cable power.
The internal-powered cable supplies power to the CAN physical layer from
the host computer. The V+ pin is not connected to any internal signals, but
the corresponding pins on the 9-pin D-Sub and the 5 pin Combicon-style
connectors are still connected. The V– pins serves as the reference ground
for the isolated signals.
The CAN physical layer is isolated from the computer in both types of
cable.
If the CAN physical layer is powered from a bus power supply, the power
supply should be a DC power supply with an output of 10 V to 30 V. The
power requirements for the CAN ports for Bus-Powered configurations are
shown in Table B-1. You should take these requirements into account when
determining requirements of the bus power supply for the system.

Cable Specifications
Cables should meet the physical medium requirements specified in
ISO 11898, shown in Table B-2.
Belden cable (3084A) meets all of those requirements, and should be
suitable for most applications.

Cable Lengths
The allowable cable length is affected by the characteristics of the cabling
and the desired bit transmission rates. Detailed cable length requirements
can be found in the ISO 11898, CiA DS 102, and DeviceNet specifications.
ISO 11898 specifies 40 m total cable length with a maximum stub length
of 0.3 m for a bit rate of 1 Mb/s. The ISO 11898 specification says that
significantly longer cable lengths may be allowed at lower bit rates, but
each node should be analyzed for signal integrity problems.
Table B-3 lists the DeviceNet cable length specifications.

Appendix B
Cabling Requirements
Maximum Number of Devices
The maximum number of devices that you can connect to a CAN port
depends on the electrical characteristics of the devices on the network. If all
of the devices meet the requirements of ISO 11898, at least 30 devices may
be connected to the bus. Higher numbers of devices may be connected if the
electrical characteristics of the devices do not degrade signal quality below
ISO 11898 signal level specifications. If all of the devices on the network
meet the DeviceNet specifications, 64 devices may be connected to the
network.
Cable Termination
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
line causes reflections that may cause communication failures.
Because communication flows both ways on the CAN bus, CAN requires
that both ends of the cable be terminated. However, this requirement does
not mean that every device should have a termination resistor. If multiple
devices are placed along the cable, only the devices on the ends of the cable
should have termination resistors. See Figure B-6 for an example of where
termination resistors should be placed in a system with more than two
devices.

Figure B-6. Termination Resistor Placement
The termination resistors on a cable should match the nominal impedance
of the cable. ISO 11898 requires a cable with a nominal impedance of
120 Ω; therefore, a 120 Ω resistor should be used at each end of the cable.
Each termination resistor should each be capable of dissipating 0.25 W of
power.
