SIMPLE-CAN - contactless CAN-BUS reader
SIMPLE-CAN is contactless adapter used to read vehicle CAN data with LV-CAN200, ALL-
CAN300. If LV-CAN200 or ALL-CAN300 connection requires two CAN lines to get all data, then
you need two SIMPLE-CAN readers
TECHNICAL DETAILS
Power supply voltage 9-63 V
Power supply current:
Mode
12V
24V
Active
8.3 mA
4.3 mA
Standby
1.6 mA
0.91 mA
CAN-BUS speeds from 33,33 to 500 kb/s
Automatically sets CAN Low, CAN High polarity
Automatically adjusts signal level and speed
SIMPLE-CAN works in the
listening mode only
, so not all the data available on the CAN-BUS
may be received using this solution. The device automatically sets CAN L/H polarity, but the
calibration has to be always executed during installation process. Connection of previously
calibrated unit to another car needs new calibration because the reader automatically adjusts
signal level and speed to different CAN-BUSes. The device also automatically adapts to the found
noise level
.

After power supply connecting, LED shines continuously. It means that device waits
for calibration. Calibration process has to be carried out when CAN-BUS twisted pair is tightened
on SIMPLE-CAN and when the ignition is ON. Please press the switch shortly and wait for the LED
to start blinking every 1 second. Automatic calibration process takes up to 10 seconds depending
on the vehicle's model. Correct calibration process is confirmed by LED's every 2 seconds blink
(when the CAN-BUS is active). When the CAN-BUS enters sleep mode, SIMPLE-CAN device does it
also and takes 1,6mA/12V. In the sleep mode LED does not shine. If after calibration process LED
shines continuously, it means that device is not calibrated yet, CAN-BUS transmission has failed
or ignition during calibration was not ON.
