2 About this manual
This manual is intended for the Kvaser LAPcan/Kvaser LAPcan II users. This manual
contains a description of the hardware’s properties and general instructions for connecting the
device to a computer.

3 Introduction
Table 1: The Kvaser LAPcan/LAPcan II devices and their EAN numbers.
Device Product Number
Kvaser LAPcan 733-0130- 00029-2
Kvaser LAPcan II 733-0130- 00115-2
Kvaser LAPcan is a PC card compliant with the PC-Card (PCMCIA) standard. It contains the
powerful microcontroller C161O from Infineon and two SJA1000 CAN controllers from Philips.
The SJA1000 handles CAN messages with 11 bit as well as 29 bit identifiers. Remote frames
can be sent and received without restrictions. Kvaser LAPcan can both detect and generate
error frames on the CAN bus. Kvaser LAPcan provides two completely independent CAN
channels with two separate connectors. The CAN bus transceivers are integrated into the
connection cables.
The Kvaser LAPcan II is an improved version of the Kvaser LAPcan card. It
is fully compatible with the Kvaser LAPcan card but features
- better performance
- improved EMC and ESD characteristics
- a different artwork on the housing (an eagle instead of a peregrine falcon)
In this text we will use the name Kvaser LAPcan for both Kvaser LAPcan and
Kvaser LAPcan II.

4 Kvaser LAPcan installation
The Kvaser LAPcan card may be inserted in any free PC Card (PCMCIA) slot
that is capable of accommodating Type II or Type III cards. You don’t have to
switch the power off before inserting or removing the card.
1
Figure 1. A Kvaser LAPcan with its two CAN ports.
Many new laptop computers are equipped with CardBus slots instead of
PCMCIA slots. You can use a CardBus slot for Kvaser LAPcan without
problems, because the CardBus controller will automatically use a special
compability mode for Kvaser LAPcan (or other PCMCIA cards)1.
The Kvaser LAPcan has two independent I/O ports that are depicted in the
figure above. You connect the card to the CAN network by means of special
cables, the DRVcans.

This is true for Windows 95, 98, ME, 2000 and XP. Windows NT 4.0 might have trouble with a
CardBus controller; please consult the computer manufacturer for more information.

6 The DRVcans
The DRVcans contain the CAN bus transceiver. There are several different
types of DRVcans, and which one to choose depends on the physical layer
your CAN system is using.

6.2 How to use the DRVcan
• Push firmly to insert the connector on the DRVcan into Kvaser LAPcan.
• To remove the connector, push both tabs (see Figure 3 below) as deep as
possible and pull out the connector.
• We recommend that you remove the card before inserting or removing
DRVcans. This is because not all software will be able to handle a “hotswap”. No damage to your Kvaser LAPcan will happen, however, if you
insert or remove a DRVcan while the Kvaser LAPcan is inserted into your
computer.

7 A Few Words of Caution
• Do not apply excessive force when inserting the card into the computer.
• Do not remove the card by pulling on the I/O cables.
• Always make sure the I/O connectors are firmly seated.
• When you remove a DRVcan, you must firmly press both the tabs (see Figure 3 below)
on the connector.
Figure 3. The I/O connector on a DRVcan. The tabs are marked with arrows.

Figure 4. The DSUB connector on a DRVcan.
The CAN bus is connected to the 9-pin DSUB connector (see Figure 4 above)
on the DRVcan.

Kvaser LAPcan / LAPcan II Hardware Guide 12(19)
Caution!
Always connect the ground pin on the D-SUB to the ground of your CAN bus.
Some laptop computers have AC power supplies that might destroy the
DRVcan unless it is properly grounded. Running the laptop from battery power
is usually OK even if the ground lines are not connected.
