This document provides important information regarding intended use, safety, installation and operation

of the device(s).

The document is intended for qualified technicians and electricians with advanced knowledge in

electrical engineering and fieldbus technology and systems, allowing them to estimate the risks and

hazards of operating the device and to integrate it into systems with components of other

2.4 GHz and 5 GHz operation.

The module can be used as CAN-WLAN/Bluetooth

interface via software.

In a wireless CAN-CAN bridge, CAN data is transmitted wireless between two WS103 modules. The CAN-

CAN bridge serves as a replacement for a CAN cable for more efficient and dependable communication

of operational data over long runs and moving joints.

The interface is suitable for use in mobile and stationary systems for industrial, agricultural, and forestry

Danfoss has no responsibility for any accidents caused by incorrectly mounted or maintained

equipment.

Danfoss does not assume any responsibility for Danfoss products being incorrectly applied or the

system being programmed in a manner that jeopardizes safety.

All safety critical systems shall include an emergency stop to switch off the main supply voltage for

the outputs of the electronic control system. All safety critical components shall be installed in such a

way that the main supply voltage can be switched off at any time. The emergency stop must be easily

after installation.

In the event of malfunctions or uncertainties, please contact the manufacturer.

Do not apply this device in machines and/or applications where life depends on the proper (fault

free) operation of the device.

Do not enable function until sufficient wireless network availability (WLAN / Bluetooth

) is ensured,

failures or malfunctions of the device can lead to erroneous data transmission.

Do not operate this device until systems are checked for conformity with legal requirements.

The device must only be put into operation by qualified technicians and electricians with advanced

knowledge of electrical engineering and fieldbus systems.

The integrator of this device is responsible to check and comply with regional directives and

requirements.

The device does not comply to the directive 94/9/EC and must therefore not be used in hazardous

areas.

The device(s) described in this manual may only be used in mobile or stationary systems in which under

normal operating conditions the separation distance between the antenna(s) and all persons is at least 20

Protect wires from mechanical abuse, run wires in flexible metal or plastic conduits.

Use 85˚ C (185˚ F) wire with abrasion resistant insulation and 105˚ C (221˚ F) wire should be

considered near hot surfaces.

Use a wire size that is appropriate for the module connector.

Separate high current wires such as solenoids, lights, alternators or fuel pumps from sensor and other

noise-sensitive input wires.

Do not run wires near hot machine members.

Provide strain relief for all wires.

Avoid running wires near moving or vibrating components.

Avoid long, unsupported wire spans.

Ground electronic modules to a dedicated conductor of sufficient size that is connected to the

battery (-).

specification includes the following restrictions:

The 802.11n standard improves the reliability of communications, the predictability of coverage, and the

overall throughput. It uses the same frequency bands as 802.11b/g and 802.11a. This means that WLAN

products based on the 802.11n standard can operate in the 2.4 GHz band, the 5 GHz band, or both.

The 802.11a specification includes the following restrictions:

channel lists are available on WS103. The 5 GHz channels can be combined.

World (2.4 GHz) - 1-11

FCC (2.4 GHz) - 1-11

U-NII-2 (5 GHz) - 52, 56, 60, 64 (FCC, IC, ETSI domain)

U-NII-2e (5 GHz) - 100, 104, 108, 112, 116, 132, 136, 140 (IC domain)

U-NII-3 (5 GHz) - 149, 153, 157, 161, 165 (FCC domain)

If the frequency bands are U-NII-2 (5.260 to 5.320 GHz) and U-NII-2 extended (5.500 to 5.700 GHz), the

module can be operated as a DFS slave / client device.

operations.

There are two types of WLAN topologies: the ad-hoc mode and the infrastructure mode. The

infrastructure mode, is used to incorporate the wireless clients into an existing wired LAN infrastructure.

In the infrastructure mode all communication is passed through the Access Points (APs) that are

connected to the wired LAN. A single AP communicating with a number of clients is called a Basic Service

Set (BSS). A number of interconnected APs with the same network name is called an Extended Service Set

(ESS). An AP that holds information about the mobile clients authorized to enter the system is called an

autonomous AP (or "fat" AP), whereas an AP that only is responsible for forwarding received data, is

called a controller-based AP (or "thin" AP). While the autonomous APs carry out all wired to wireless

Two WS103 modules can be configured as a CAN-CAN bridge. Every (or selected) CAN message received

by one WS103 is sent through Wi-Fi

and managed by the second WS103. For more information see
