ure 1.1: Block-circuit diagram of CAN-USB/2 module
The CAN-USB/2 module is an intelligent CAN interface with an ARM LPC2292 micro controller for
local CAN data management. The module supports the USB 2.0 Hi-Speed interface with data transfer
rates of 480 Mbit/s.
The ISO 11898-compliant CAN interface allows a maximum data transfer rate of 1 Mbit/s. Like many
other features of CAN interfaces, the bit rate can be set by means of software.
CAN interface and other voltage potentials are electrically isolated by means of a digital isolater and
DC/DC converters.
The supply voltage is fed via the USB bus.
The module is equipped with four green LEDs in the front panel which indicate the current module
status.

2. Hardware Installation
Installation
p
rocedure:
1. Switch off the PC and all connected peripheral devices (monitor, printer, etc.). Additionally,
switch off all other CAN devices to whose network the CAN module is to be connected in this
procedure.
2. Connect the CAN-USB/2-module with the USB bus of the PC.
3. Connect the CAN bus to the 9-pin male DSUB connector.
Please remember that the CAN bus has to be terminated at both ends. esd offers T-connectors and
terminators. Additionally, the CAN-GND-signal has to be grounded at exactly one point in the
CAN network. Therefore the CAN termination connectors have got a grounding contact. A CAN
device whose CAN interface is not electrically isolated corresponds to the grounding of the CAN-
GND.
4. Connect your PC to mains again.
5. Switch on the PC, the peripheral devices and the other CAN bus devices.
6. End of hardware installation.
Note: The software installation is described in the manual ‘CAN-API, Installation Guide’.
