Introduction
1 Introduction
1.1 Overview
The CANcheck allows simple testing of CAN networks during commissioning,
maintenance and troubleshooting. The battery-operated, portable device is con-
nected to the CAN network to be tested and operated via a clearly structured
menu.
The CANcheck measures line parameters – with network switched off1– and op-
erating parameters – with network switched on.
Via line parameters it is checked whether the CAN network was correctly in-
stalled. Short-circuits, interruptions and incorrect cable properties are quickly de-
tected.
Via operating parameters it is checked whether the nodes in the CAN network are
working correctly. Missing identifiers and poor signal levels are quickly detected
and can be allocated to the individual CAN nodes.
1Generally in the case of tests of line parameters, all CAN nodes should be disconnected from the CAN
network. Switched off nodes with a high internal resistance can remain connected.

Introduction
1.2 Functions and performance features
Tests of the line parameters with network switched off
• Resistance measurement between all pins of the CAN connector (assignment
in accordance with CiA) and analysis based on pre-defined limit values
• Measurement of the termination resistors
• Determination of the cable length
• Determination of the cable impedance
Tests of the operating parameters with network switched on
• Measurement of the voltage between CAN_V+ and CAN_GND
• Determination of the baudrate of the tested CAN network (list in accordance
with CiA) and test of polarity
• Measurement of the bus load of the tested CAN network and of the propor-
tion of error telegrams
• Operating mode layer 2: determination of all transmitted 11-bit and 29-bit
identifiers and display of the frequency of reception
• Operating mode layer 2: absolute and differential signal level listed by identi-
fier
• Operating mode CANopen: frequency of reception and signal level listed by
node ID
Other performance features
• Summarized tests with test instructions, test result, continued after confirma-
tion
• All test results are stored and can be seen on the display after the test
• The test results can be transferred to the PC for printing and filing
• Test instructions and results in German or English
• Power save mode
• Power-on self-test of the device

Ports
2 Ports
The CANcheck has one CAN connector, one USB connector and a battery com-
partment. The trigger output is connected to 2 reserved pins of the CAN connec-
tor.
2.1 Pin assignment
2.1.1 CAN connector
The pin assignment on the CAN connector corresponds to CiA DS-102. The trig-
ger output is connected to 2 pins, which are marked as “reserved” in CiA DS-102.
The trigger output is galvanically isolated from the CANcheck ground and has an
internal resistance of 1 kΩ.
Pin Signal Description
1 - Reserved
2 CAN_L CAN bus signal (dominant low)
3 CAN_GND CAN ground
4 TRIGGER_SHLD Return wire of the trigger output
5 CAN_SHLD Optional shield
6 GND Optional CAN ground
7 CAN_H CAN bus signal (dominant high)
8 TRIGGER Trigger output
9 CAN_V+ Optional external power supply
Vcc
2.1.2 USB connector
If the CANcheck and the PC are connected via USB, the device is supplied from
the PC. The USB connector is galvanically isolated from the CANcheck ground.
Pin Signal Description
1 +5V Power supply
2 D- Negative data line
3 D+ Positive data line
4 GND Ground

Ports
2.2 Battery compartment
The CANcheck is powered by 4 x 1.5 V batteries or 4 x 1.2 V rechargeable batter-
ies Mignon (AA). The battery compartment is on the back of the device. To re-
place the batteries you require a slotted screwdriver (blade width approx. 5 mm).
Please use it to press the plastic spring of the catch together and carefully lift off
the cover.
Please note:
• The rechargeable batteries cannot be recharged via the USB connector.
Please remove the rechargeable batteries from the battery compartment and
recharge them in a commercial battery charger.
• For rechargeable batteries, the capacity given by "Settings/Battery voltage" is
not valid. It is only valid for batteries.
• For rechargeable batteries, please check the voltage given by "Set-
tings/Battery voltage". You should recharge the rechargeable batteries when
the voltage drops below 4.8 V.
2.3 Trigger output
When a configurable 11-bit or 29-bit-identifier is received, the CANcheck gener-
ates a signal pulse on the trigger output. The signal pulse has the following prop-
erties:
• positive and negative signal pulse at the end of the telegram
• 10 V peak-peak without load
To use the trigger output, connect the CAN/trigger cable (see section 10.2) to the
CANcheck. The "SUB-D9 connector with CAN cable and BNC cable" belongs to the
CANcheck. The "SUB-D9 connector with CAN cable" belongs to the CAN network.
Usually, an oscilloscope is triggered by the trigger output. The telegram of the
configured 11-bit or 29-bit identifier is then displayed on the oscilloscope. In this
way the level measurements of the CANcheck can be supplemented with meas-
urements with the oscilloscope.

Operation
3 Operation
The CANcheck has a display and a keyboard. It is switched on and off via the key-
board.
3.1 Switching on and off
Switch the CANcheck by pressing any key for more than 1 second. The name
IXXAT then appears on the display and moves downwards before disappearing.
End this test screen by pressing a key again. Then the message "Self-test passed"
appears for 1 second. Then the system menu is displayed.
In power save mode (default setting), the CANcheck automatically switches off
after 10 minutes without a user input. Generally the CANcheck consumes little
power while waiting for a user input.
However, if you wish to switch the CANcheck off immediately select the menu
item "Settings" and then the sub-item "Switch off". Please confirm the selection
with "Off".
3.2 Display
The CANcheck is equipped with a graphical display with 128 x 64 pixels. The dis-
play shows the menu items and the test results.
One header line and up to 6 lines of text are shown on the display. If the space is
not sufficient, the content can be moved with the help of the keyboard.
The display has a background illumination. In the default setting the background
illumination is switched off. You can switch the background illumination on by
selecting the menu item "Settings" and then the sub-item "background illumina-
tion". Please then select "Automatic" and confirm the selection.
In the "Automatic" setting, the backlight switches on every time a key is pressed
and off again automatically after 20 seconds.
The background illumination is always switched on when the CANcheck is con-
nected to a PC via a USB cable.
3.3 Keyboard
The CANcheck is operated via a keyboard with 6 membrane switches. Move the
selection bar from menu item to menu item with the keys UP and DOWN. Con-
firm your selection with the OK key. The selected menu item then becomes the
new header.
The CANcheck is operated via the system menu and sub-menus. Move from the
system menu to the sub-menu with the OK key. Move back with the ESC key.
You can cancel every menu item with the ESC key. You can also cancel every test
with the ESC key.
