Encryption helps to protect the information sent over the air. That way an intruder will not be able to
access the information that is sent over the air. The encryption types used are WEP, WPA, WPA2, PEAP,
EAP-TLS (planned). Security can be divided in two parts:
•
Authentication ensures that the identities of the two communication peers are correct and can be
trusted.
•
Privacy aims to protect the communication from eavesdropping by encryption. Authentication and
privacy are independent of each other but are often specified to be used together.
Bluetooth
®
mode
Bluetooth ® is a global wireless communication standard that connects devices together over a certain
distance. The most common today are Bluetooth ® BR/EDR (basic rate/enhanced data rate) and Bluetooth ®
with low energy functionality. WS103 includes both Bluetooth ® Classic (2.1 + EDR) and Bluetooth ® Low
Energy (planned). In order to use Bluetooth ® technology, a device must be compatible with the subset of
Bluetooth ® profiles necessary to use the desired services. A Bluetooth ® profile is a specification regarding
an aspect of Bluetooth ® -based wireless communication between devices. The Serial Port Profile (SPP)
service is used to establish a communication between the laptop and WS103 via Bluetooth ® .

Service Tool
With WS103 installed on the CANbus of a machine equipped with PLUS+1 ® control system, it can be
configured to be paired with a laptop and the user can connect wirelessly to a PLUS+1 ® control system
and manage it remotely by using the PLUS+1 ® Service Tool. For more information see WS103 Remote

Classic CAN to CAN bridging
Two WS103 modules can be configured as a CAN-CAN bridge. Every (or selected) CAN message received
by one WS103 is sent through Bluetooth
® and managed by the second WS103. For more information see
