The CANtouch supports these bus systems in physical layer measurements: CAN, CANopen, DeviceNet, and SAE J1939.
You can also use it for measurement in other bus systems based on the CAN standard. These include Isobus, NMEA 2000, and SafetyBus P and Energy bus, CANaerospace, and ARINC825. Niche bus systems also include MilCAN and CANopen Lift.
Software License Model
The big range of functions is not often needed in whole. To set the device to an attractive price worthy level, a license model was established. The not included functions can be tested in a 30 day trial time. At this time, there are no functional limitations. To get a function unlocked forever, a license has to be purchased.
So you are deciding on your own which functions are needed in your case and what is worthy of investing in.
Even the hardware doesn’t have to be purchased completely. The basic set comes without a service case and adapter set.
The CANtouch is a battery-operated handheld diagnosis device for physical and logical CAN bus analysis. With its modern touch control, it allows intuitive and efficient handling without an additional computer.
As further development of the CAN-Bus Tester 2, it has not only its functionality; it has new additional measurements as well. An easier valuation procedure with traffic light colors and smileys supports your work with a quick valuation of the measures.
With the possibility for future updates, you are equipped for further enhancement. New functionality can be unlocked by purchasing additional licenses. In addition, we provide new software within the scope of product maintenance, which can be downloaded free of charge by every owner of a CANtouch. Many new functions are made available free of charge.
The integrated battery supplies power to the device without a problem for a whole intense measurement day. It is monitored by a special charge controller that calculates the remaining time and residual charge. If all that is not enough – the device is charged up to 80% in only one hour regardless of whether you are measuring at that time or not.
The rubberized aluminum continuous casting body is not only impressing high quality, but it is also extremely robust.
With traffic light colors red, yellow, and green plus a display as smiley, you gather rapidly how your system is doing today.
By clicking on the smiley, it shows the basis of valuation.
You can set the threshold values via an XML file to make individual specifications for the evaluation. You have always loaded the appropriate rating file for your system after a one-time setup through the project management.
After selecting the right bus system, you have more options for choice. The device is searching for the correct baud rate, but it is also possible to choose one by hand. Beyond that, you can change the bit timing, which is essential for systems that are not running on CiA standards.
Besides this, you should choose the right ground reference point, whether the external ground connection or CAN_V- which is connected to pin 6 of the 9‑pin sup D socket.
Your settings for the CAN bus are saved project-related.
In the control center, you can quickly reach the most important settings.

- Keypad sound
- Automatic brightness
- Basic setting Brightness
- Baud rate
- Baud rate scan
- Jump to the Bit timing menu
- List Only /Bus Actual switching
- A changeover of the mass reference point

- Device settings
Language, brightness, switch-off delay, time
- Project management
Creating, deleting, and naming projects
Project-related bus settings
Project-related rating settings
- A possibility to reset the device to factory settings.
You can store the measurements of single nodes and the results measured by the apps Bus Wiring and Online Trigger in an archive file in a folder of the device’s flash drive. So they can be opened and analyzed later on by the device itself or a computer. You need the CAN-Bus Tester 2 user software, which is freely downloadable on this website for importing to the computer.
Besides that, you can save screenshots for documentation of all other measurements. More about that in the next menu item.
The CANtouch can save up to 100 screenshots per project.
Simultaneously pressing the buttons “Power” and “Home,” another screenshot is made and saved to the flash drive. You can also access this function via the control center. If you reach the maximum number of screenshots, the device will delete the oldest.
With this feature, you can report the device’s functions and all measurements. The png-format files can be opened or imported into many software and documents.

Measurements in detail
Automatic Quick Test
This function provides an immediate overview of the status of all measured values that the CANtouch can determine on the CAN bus. For this purpose, the used baud rate is automatically detected and a continuous measurement starts. The evaluation of all measurement results of the six free apps is done by a smiley. Even an evaluation of the quality levels of all bus participants is carried out continuously, even if no license for the measurement has been acquired. The smiley represents the worst measurement result of the last measuring cycle. With one click you can start the corresponding measurement to start a troubleshooting.
If this test is carried out with good results, a faultless bus can be assumed in many cases. This also enables less specially trained personnel to be able to exclude or identify a faulty CAN bus.
|Common mode voltage||This measurement shows potential differences between the nodes of the bus. To know what this means please refer to the corresponding article.|
|CAN level difference||This measures the difference voltage between CAN_H and CAN_L.|
|CAN level absolute||The absolute levels of the bus system are the real voltages on the line in both bit conditions in relation to a reverence ground.|
The bus wiring test checks the bus for shorts and breaks. In addition, it measures values like total line length, termination resistors and loop resistance.
Mainly made for a check while setting up a system, the measurement is also widely used for troubleshooting.
The quality levels of the sending nodes are displayed in a bar chart. Variations and fluctuations are easy to detect. Min/max values are stored. An extended view also shows the combination of the percentages in the quality value.
The individual participants can be measured even more detailed. The display shows the disturbance-free voltage range, edge steepness and quality level next to a logical or physical oscillogram of the node’s telegrams.
The smileys allow judging the measurements at a glance.
By using predefined lists of nodes, it is easier to find out if a node is missing.
The Online Trigger is used for monitoring the bus, looking for logical errors and physical layer problems over a longer time period. Measurement can be started after choosing the time for one measurement cycle (10 ms – 1 min). If an error is detected within a measurement cycle, it is marked within the corresponding line. So it is later possible to see when an error occurred (up to 1 week). The chosen time for one cycle is accountable for the maximum displayable time span. 10.000 measurement cycles are displayable in CANtouch, older data gets lost. Only the fact that one or more errors occurred over the whole measurement time is visible.
For physical measurements, you give thresholds, when an error is shown. Current values, as well as maximum and minimum values, can be shown. Monitoring for certain errors can be switched off. This might be usable in case you are looking for a certain physical problem and don’t want the monitor to beep or to be stopped at every error frame.
The CANtouch can beep at every recognized error, this makes it easier to troubleshoot sporadic errors. It is also possible to show the last as corrupted assessed message as oscilloscope picture. The functions of the oscilloscope view are detailed as known from the Node Measurement app (zoom, physical and logical view, decoding).
The extensive protocol monitor can send individual telegrams or sequences of telegrams.
On receipt, the data is displayed in list form or in overwriting, the data content is displayed in original or decrypted form and can be recorded for later evaluation. The long-term recording (trace) can be influenced by start/stop conditions.
The free symbol editor is available in the support area as a download to configure decoding.
The send and receive lists as well as trace data can be imported into the CANvision software. No purchase is necessary, the software can be operated in trial mode. In addition, we allow free decoding of CANopen and SAE J1939 data including ISOBUS and NMEA2000.
