Basic testing of the connection to the AKD controls
When the AKD is switched on, a boot-up message is transmitted over the bus. The telegram continues to be
transmitted, as long as it has not yet found a suitable receiver in the bus system.
If a CAN master is unable to recognize this message, then the following measures can be taken to test com-
munication:
l Check the bus cable: correct characteristic impedance, correct termination resistors at
both ends?
l With a multimeter: check the quiescent level of the bus cables CAN-H and CAN-L against CAN-GND
(approx. 2.5 V).
l With an oscilloscope: check the output signals on CAN-H and CAN-L at the AKD. Are
signals being transmitted on the bus? The voltage difference between CAN-H and CAN-L for a logical "0"
is approx. 2-3 V.
l Does signal transmission stop if the master is connected?
l Check the master hardware.
l Check the master software!
