CAN Repeaters, Routers, Optical Links and hand held Diagnostics Unit

PCAN Repeater


The PCAN-Repeater creates a connection between two High-speed CAN busses with galvanic isolation of up to 5 kV. Bus rate is automatically sensed but both busses must operate at the same speed. Both CAN channels are decoupled from each other and from the power supply. CAN messages are forwarded 1:1 between the two channels and may be forwarded uni-directionally if required. LEDs display the current bus status. Each CAN channel can be selectively terminated

With its DIN rail casing and extended temperature range support, this module is suitable for use in an industrial environment.

A Repeater will isolate sections of a CAN bus but will reduce the length of a bus by its delay time and cannot be used to extend the bus.

PCAN Router


A CAN Router as it takes information from one CAN bus, filter or modify it and send it to a second bus so a Router can be used effectively to extend a bus by splitting it into two parts.  

The PCAN-Router is a module that accesses two separate CAN networks. It uses a programmable ARM microcontroller to process the data it sees on these two channels , so that incoming CAN messages can be evaluated, converted, and filtered individually, in order to transmit appropriately customized CAN messages to the other network.

The PCAN-Router is shipped with demonstration firmware which performs one-to-one forwarding of the CAN messages between the two CAN networks at 500 kbit/s.   The source code for this application and a GCC compiler and GDB environment is included on the CD-ROM supplied with the units. It is possible to load your own firmware onto the module via CAN by means of a pre installed boot loader.

The two networks need not operate at the same speeds however buffering software would need to be written by the user to cope with any resulting queues of messages. 

The module is mounted in an aluminium casing, and is shipped in versions with two Sub-D connectors, or a screw-terminal strip.  A power supply 7-26V DC is required.

The router can be fitted with an additional LIN channel if required and the Sub-D connector version also has an additional digital line. A version with galvanic isolation is available Sub-D only

PCAN Router DR

AS described above but in a plastic DIN Rail package for use in industrial environments.  Bit rates can be set with a front panel switch and CAN1 is isolated up to 5kV from CAN2 and the power supply (compliant with ICE 60601-1).  Ask for a copy of the user manual to see the full range of diagnostic aids supplied.

PCAN Router FD


The PCAN-Router FD allows the connection to two CAN FD or CAN busses. Based on a ARM Cortex M4F microcontroller, the module's behaviour and the data routing between both CAN FD channels is freely programmable. In particular, the module allows the conversion from CAN to CAN FD or vice versa. This makes it easy to accomplish the integration of CAN FD applications into existing CAN 2.0 networks.

Using the programming library and the GNU compiler for C and C++, a firmware is created and then transferred to the module via CAN. On delivery, the PCAN-Router FD is provided with a demo firmware. The corresponding source code is included as example in the scope of supply.

The module is installed in an aluminum profile casing, and is shipped in versions with two D-Sub connectors or a screw-terminal strip.



PCAN Router Pro


The PCAN-Router Pro allows the data traffic from up to four High-speed CAN busses to be connected together.

As well as pure forwarding, the CAN data can be processed, manipulated, and for example filtered in a number of different ways. To do this, the behaviour of the PCAN-Router Pro can be freely configured using comprehensive Windows software. There are a variety of function blocks and other settings available to the user to allow this kind of configuration to be set up.

At the same time, there is a virtual fifth CAN channel which is responsible for recording some or all of the data traffic to a Compact Flash card.  A battery powered real-time clock (RTC), can  be used for logging and wake-up.

A modular bus structure allows specific transceivers to be fitted to allocated channels on request. For example, High speed CAN is standard but opto-decoupled, Low-speed and Single wire CAN transceivers are also available on request and CAN termination is switchable.

As an alternative to the standard firmware which the PCAN-Router Pro is equipped with at delivery, custom firmware based on the ARM microcontroller NXP LPC2294 can be created and implemented. A library and the Yagarto GNU ARM toolchain (contains the GNU Compiler Collection GCC for C and C++) are included with some example configurations.

Although designed as a Router these units could ( within the limits of their single chip micros) be used as a network controller and data logging device for simple systems

PCAN-LWL Optical link


The PCAN-LWL package enables any CAN section to be implemented with an optical link. The optical waveguide consists of a 62.5/125 μm duplex fibre optic cable with ST connectors. Conversion can be to High Speed CAN or Low Speed CAN and termination selected with internal jumpers.

Areas of application include EMC measurements on CAN modules, CAN sub-sections with high electromagnetic irradiation and lines that pass through areas where there is a risk of explosion.

The package supplied contains two modules complete with 5 meters of fibre optical cable including connectors. The modules require an external power supply or they can be powered by batteries. A suitable battery is available as an option.


A LIN version of this device is also available  PLIN-LWL

PCAN-DIAG a hand held bus diagnostic unit


PCAN-Diag 2 is a handheld diagnostics unit with a wide range of functions to allow investigation of the correct operation and performance of a CAN bus, such as detection of the CAN bit rate, bus load measurement, and termination measurement.  As well as receiving CAN messages, it can transmit either individual test messages or entire sequences of them. In addition, the internal memory card allows tracing and playback of the CAN traffic.

The integrated two-channel oscilloscope enables visualization of CAN signals. Single CAN IDs and various events can be used as triggers. The CAN frames are decoded from the analogue signal, for example, to detect errors in the frame.

Incoming CAN messages can be displayed symbolically for clear and easy identification. The PCAN Symbol Editor software supplied with this product enables convenient creation of the symbol files needed for this feature.

Output is through an OLED colour display which allows excellent readability even when there is strong ambient light. The user selects and operates the individual diagnostic functions using a push dial. Normally supplied with High-speed CAN transceiver modules, Low-speed or Single-wire CAN are also available.
