Connecting the LambdaCANp module

Power and CAN connections to the module are made using the Eurofast 12mm connector on the
module. The power input requirement is 11 to 30VDC at 12W (steady-state).  At start-up, there
can  be  a  peak  power  draw  of  up  to  40W.  Multiple  modules  can  be  connected  together.  All
modules are configured to broadcast CAN messages at the default CAN baud rate of 500kBits/s
(to change the baud rate see section 8.12). The maximum distance between any two nodes on the
CAN  bus  operating  at  a  500kBit/s  baud  rate  is  100m.  Each  end  of  the  CAN  bus  must  have  a
terminating resistor of 121 Ohms.

Application Notes

1.

Configuration software (ECM Configuration Tool) for the module is located on the CD. This
software allows the setup, configuration, monitoring, and recording of data using supported
CAN adapters.

2.

The Lambda sensor supplied with LambdaCANp is already calibrated with the calibration
residing in a memory chip in the sensor’s connector. To compensate for sensor ageing, the
sensor can be spanned using ambient air, (it is not necessary to zero the sensor). See section
8.1 for instructions on how to perform a span of the O

2

measurement.

3.

Do  not  extend  the  wires  between  the  Lambda  sensor  and  the  control  module.  You  can
lengthen the power wires on the DC Power Cable (P/N: 11-01 or 11-02) but use large gauge
wire and make sure that the voltage at the power terminals of the supplied harness is at least
11  V  when  the  sensor  is  being  heated.  You  can  lengthen  the  CAN  communication  wires
using  Eurofast  12mm  cable.  Eurofast  12mm  cable  was  designed  specifically  for  CAN
communication and along with additional “Tees”, allows you to easily build long and reliable
CAN networks.

4.

The  LambdaCANp  broadcasts  several  messages  on  the  CAN  bus  using  the  CANopen
protocol.  Each  message  has  an  identifying  number  known  as  the  CAN  identifier  (CANid).
Since  multiple  modules can  be  placed  on  the  same  CAN  bus,  each  module  on  the  bus  also
has an identifying number known  as the node identifier (NID).  The allowable range for the
NID  is  0x01  to  0x7F.  When  connecting  other  non-ECM  devices  on  the  same  CAN  bus,
ensure that the following CANids are not used:

Message type

CANid (hex)

NMT

0x00

Emergency

0x80 + NID

TPDO1

0x180 + NID

TPDO2

0x280 + NID

TPDO3

0x380 + NID

TPDO4

0x480 + NID

SDO Tx

0x580 + NID

SDO Rx

0x600 + NID

Heartbeat

0x700 + NID

LSS

0x7E4, 0x7E5

(Note: this list applies to EACH ECM module on the CAN bus)
