CANcheck Manual, Version 2.1
1 Introduction
1.1 Overview
The CANcheck allows simple testing of CAN networks during commissioning,
maintenance and troubleshooting. The battery-operated, portable device is
connected to the CAN network to be tested and operated via a clearly structured
menu.
The CANcheck measures line parameters – with network switched off1– and
operating parameters – with network switched on.
Via line parameters it is checked whether the CAN network was correctly
installed. Short-circuits, interruptions and incorrect cable properties are quickly
detected.
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.

1.2 Functions and Performance Features
Notice
HMS recommends to calibrate the CANcheck every two years to ensure the
accuracy of measurement. For further information please contact HMS.
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
proportion 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
identifier
•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
confirmation
•All test results are stored and can be seen on the display after the test
•Plausibility check of stored test results
•Permanent storage of up to 4 test results
•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

CANcheck Manual, Version 2.1
2 Ports
The CANcheck has one CAN connector, one USB connector and a battery
compartment. The trigger output is connected to 2 reserved pins of the CAN
connector.
2.1 Pin Assignment
2.1.1 CAN Connector
The pin assignment on the CAN connector corresponds to CiA DS-102. The
trigger 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.

2.2 Battery Compartment
The CANcheck is powered by 4 x 1.5 V batteries or 4 x 1.2 V rechargeable
batteries Mignon (AA). The battery compartment is on the back of the device.
To replace the batteries a slotted screwdriver (blade width approx. 5 mm) is
required. Use it to press the plastic spring of the catch together and carefully lift
off the cover.
Note:
•The rechargeable batteries cannot be recharged via the USB connector.
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, check the voltage given by “Settings/Battery
voltage”. 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 or an error frame is received, the
CANcheck generates a signal pulse on the trigger output. The signal pulse has
the following properties:
•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 11.2) 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 or the error frame is then displayed on the
oscilloscope. In this way the level measurements of the CANcheck can be
supplemented with measurements with the oscilloscope.

Operation

CANcheck Manual, Version 2.1
3 Operation
The CANcheck has a display and a keyboard. It is switched on and off via the
keyboard.
3.1 Switching On and Off
Switch on the CANcheck by pressing any key for more than 1 second. The
message “Self-test passed” appears for 1 second on the display. Then the
information on the use of CANcheck is displayed (see chapter 11.4). Confirm
this information with the OK key. 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.
To switch the CANcheck off immediately select the menu item Settings and the
sub-item Switch off. Confirm the selection with Off.
3.2 Display
The CANcheck is equipped with a graphical display with 128 x 64 pixels. The
display 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. To switch the background illumination on, select the
menu item Settings and the sub-item background illumination. 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
connected 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.
Confirm 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.
Every menu item and test can be cancelled with the ESC key.
If the pixels of the display are not sufficient, move the contents to the left or right
with the keys LEFT and RIGHT. With long lists scroll through the text with the
