Page 7: Introduction
1 Introduction 1 Introduction Thank you for purchasing CANtouch ®. You have acquired a tool supporting you in the start-up, analysis, monitoring and servicing/maintenance of your CAN bus system. Thanks to its wide range of applications, its high data transfer rate and above all through its high tolerance against interference in the field of plant automation, the CAN bus has been well established for the last few years. -
Page 8: Start-Up
Always handle the CANtouch ® with the required care. Its display is made of glass and thus may break if the device falls on a hard surface or is subjected to hard impact. Before turning on the CANtouch ® , allow the de- vice to warm up to room temperature. -

3 Overview of the CANtouch® 3 Overview of the CANtouch ® 3.1 Connections 3.1.1 Power supply / charging Only the supplied power supply unit must be used for power supply and charging of the integrated battery via the extra-low voltage socket. It possesses a wide-range input designed for connection to mains voltages from 115 V to 230 V with 50/60 Hz. -
Page 10: Using The Adapter Set
3 Overview of the CANtouch® 3.1.3 Using the adapter set An adapter set is available as an option to connect the CANtouch ® to networks by way of 9-pin subminiature D connectors or M12 plug connectors (see also Section 21 "Ordering Information"). -

Page 13: License Management
Measurement Monitor To be able to use the optional measurements, you must purchase the appropriate license. Then, a license file (*.cbthlic) is made available to you. Copy this file to the drive of the CANtouch ® as connected via USB. -
Page 14: Bus Status Measurement
The bus status provides a quick overview of the status of your CAN bus system. A cyclic measurement over one second indicates whether or not data traffic (level change) is present and whether or not the CANtouch ® connected correctly to the bus. If the system is stopped (no data traffic), the idle level of the bus is measured and evaluated. -

Page 16: Bus Voltage Measurement
Make sure that the shield and CAN_V- are connected both to each other and to the protective earth. Check the shield for short-circuits and interruptions. Check the shield for correct earthing. The shield voltage measurement need not be performed if you use own shield wiring technologies deviat- ing from those as recommended. Document: 22580-HB-1-6-E-CANtouch... -

+7 V. Even if state-of-the-art CAN transceivers permit higher values as those of the specified range, higher common-mode voltages can result in errors in the communication and finally in destruction of the transceivers. On bus traffic the CANtouch ® continuously measures the absolute signal levels of all CAN modules relative to the position of the tester and determines highest difference of their signal levels –... -
Page 18: Can Level Difference Measurement
Check the cable for short-circuited or interrupted CAN_H or CAN_L signal lines. – To this end, use the "Bus Wiring" measurement. Check that the bus is correctly terminated - the resistance at both ends must be 120 Ω. Remove individual modules temporarily to rule out faulty CAN transceivers.

Check the cable for short-circuited or interrupted CAN_H or CAN_L signal lines. – To this end, use the "Bus Wiring" measurement. Check that the bus is correctly terminated - the resistance at both ends must be 120 Ω. Remove individual modules temporarily to rule out faulty CAN transceivers.

Page 20: Bus Wiring
Select the plug connector used in your system to display an assignment of the signals to the pins in the plug connector. The values of the terminators are evaluated by CANtouch ® The measured loop resistance values should coincide with the measurement values of the cable of appropriate line length used. -
Page 21: Node Measurement
Through this a copy of the current document is stored in the "Archive" folder on the drive of the device with ascending numbering. The number of already archived measurements is displayed in the icon. 13.1 General The "Node Measurement" realizes the most important measuring function of CANtouch ® - the node-related physical measurement of the physical bus characteristics. -
Page 22: Measurement Of All Nodes
Check that the bus is correctly terminated - the resistance at both ends must be 120 Ω. Check your bus with reference to the maximum permissible cable and branch lengths for your baud rate. Remove individual modules temporarily to rule out faulty CAN transceivers. Replace individual modules or cable segments. Document: 22580-HB-1-6-E-CANtouch... -

Auto shutdown: Use this menu item to specify after which time the CAN- touch is shutdown in the standby mode automatically. ® Button sound: Use this menu item to specify that the CANtouch ® plays a sound when a button is pressed. To this end, activate this menu item. -
Page 28: Can Bus
If you do not want the CAN controller to generate an "Acknowledge" at the bus, activate the "Listen Only" option. Then, no CAN messages can be sent. 15.2.3 Reset Select "Reset all settings" to reset all settings of the CANtouch ® to the factory settings. The measuring data remain stored. -
Page 29: Meas. The Physical Bus Characteristics Per Node
Contrary to the quality level providing a general evaluation of the signal quality for the bus, the determination of the disturbance-free voltage range and of the edges, as well as the oscilloscope display are useful aids for targeted troubleshooting. Definition of disturbance-free voltage range, peak-to-peak voltage and signal level Document: 22580-HB-1-6-E-CANtouch... -
Page 30: Disturbance-Free Voltage Range
By using the existing process to measure the disturbance-free voltage range, sometimes drops in recessive bits could not be identified securely. Thus, the CANtouch firmware version v1.80 and the CAN-Bus Tester 2 PC software v4.4.0.0 and newer versions of them offer an enhanced measurement process by default. The manufacturer highly recommends to use this enhanced process for new measurements. -

16.4 Oscilloscope display with message frame analysis To be able to evaluate signal transitions and measure reflections, CANtouch ® records the signal characteris- tic of the measured message frame and represents it on the oscilloscope display of the "Node Measure - ment". -
