2 Introduction
This section describes the functions and features of the Kvaser Air Bridge Light HS.
2.1 Welcome to Kvaser Air Bridge Light HS
Figure 1: Kvaser Air Bridge Light HS
Kvaser Air Bridge Light HS is a small, yet advanced, wireless CAN bridge that can
be used as a CAN system gateway between two CAN networks. The Kvaser Air
Bridge Light HS consists of a preconfigured pair of plug and play units.
This guide applies to Kvaser Air Bridge Light HS devices listed in Table 1.
Device Product Number
Kvaser Air Bridge Light HS 73-30130-00808-3
Kvaser Air Bridge Light HS (FCC) 73-30130-01008-6
Table 1: Kvaser Air Bridge Light HS devices and their EAN numbers.
The (00808-3) Kvaser Air Bridge Light HS is approved for the European Union,
while (01008-6) Kvaser Air Bridge Light HS (FCC) is optimized for the US. They
both share the same functionality but have different radio transmitting schemes
due to regulatory differences.
Throughout this document, we use the name Kvaser Air Bridge Light HS to mean
any one of the different Kvaser Air Bridge Light HS products listed in Table 1,
unless otherwise stated.

3 Kvaser Air Bridge Light HS hardware
In this section you can read more about the CAN channel, power supply and LED
indicators.
3.1 Hardware installation
The Kvaser Air Bridge Light HS consists of two preconfigured and paired CAN bus
units. Just connect and power them through your CAN system, no user
configuration, software tools or drivers are required.
When connected to your system, the two units will determine the bit rate used by
the attached CAN buses using Auto Baudrate Detection (see Section 3.5, Auto
Baudrate Detection, on Page 8). Once the Auto Baudrate Detection has completed
successfully, the units will transmit CAN messages back and forth until the units
are powered down.
The Kvaser Air Bridge Light HS will only forward CAN messages between the two
attached CAN networks. Error frames and arbitration information will not be
forwarded since this information is only applicable for the local physical network.
3.2 CAN channel
The Kvaser Air Bridge Light HS has one CAN Hi-Speed channel with a 9-pin
D-SUB CAN connector. See Section 4.2, CAN Connector, on Page 11 for details
about the pinout.
Figure 2: 9-pin D-SUB CAN connector
3.3 Power supply
The Kvaser Air Bridge Light HS is powered through the CAN connector. To operate
the Kvaser Air Bridge Light HS, you must supply 9 V-36 V DC power through the
CAN connector.

3.4 LED Indicators
The functions of the LED indicators on the Kvaser Air Bridge Light HS are shown in
Table 2 on Page 8.
Figure 3: LEDs on the Kvaser Air Bridge Light HS.
LED Description
CAN (Yellow) CAN channel status, indicate received and sent messages.
RF (Blue) Radio Link status, indicate received radio packets.
POWER (Green) Power indicates that the unit has been powered on.
Table 2: LEDs on the Kvaser Air Bridge Light HS.
3.5 Auto Baudrate Detection
The Kvaser Air Bridge Light HS provides an Auto Baudrate Detection feature which
will automatically detect and connect to any of the following CAN network speeds:
1 Mbit/s, 500 Kbit/s, 250 Kbit/s, and 125 Kbit/s.
The Auto Baud Rate Detection is done locally, so a Kvaser Air Bridge Light HS can
be used to bridge two different CAN networks operating at different bitrates.
However, the amount of traffic on the networks will determine whether the system
designer should allow the networks to be bridged via the Kvaser Air Bridge Light
HS.
The Auto Baud Rate Detection is driven by the reception of CAN
messages on the CAN network. This means that there needs to
be existing CAN traffic on the network for the Auto Baud Rate
Detection to work.

Kvaser Air Bridge Light HS User’s Guide 9 (17)
If, after 15 seconds of power on, only one of the paired units have done a
successful Auto Baud Detection, the other unit will be configured to the same baud
rate. The Auto Baud Rate Detection will continue even after 15 seconds, if no
baudrate has been detected on either of the connected CAN networks.
If the Kvaser Air Bridge Light HS is used to bridge two different
CAN networks operating at different bitrates, both CAN networks
needs to send messages during the initial 15 seconds after
power on in order for the Auto Baud Rate Detection to correctly
detect the different bitrates.
For any additional/specific baudrate requirement, please contact Kvaser for more
info.
