1. Overview
1.1 Module Description
Fig. 1.1: Block-circuit diagram of the CAN-Bluetooth module
CAN Bluetooth is an intelligent CAN-interface with a PowerPC-micro controller for local data
manageme
nt. CAN Bluetooth enables a wireless transmission of fieldbus data across a range of up to
10 metres.
The CAN-interface is ISO 11898-compatible and permits a maximum data-transfer rate of 1 Mbit/s. Like
many other features of the CAN-module the bit rate can be configured via software.
Via the optionally available charging battery (accumulator) CAN-Bluetooth can be operated without
stationary power supply. You can operate the CAN-Bluetooth module also via a 9 V-power pack,
however.
Four LEDs in the front panel signal the wireless and CAN activities and the state of charge for the
accumalator. In order to prevent the accumulator from deep discharging the module automatically
switches off when the red LED has blinked for five minutes.
