APPENDIX 3. CONNECTING THE CAN AND CAN BUS
TERMINATION
In order to have communication on the CAB bus „CAN BUS TERMINATION“ must be done.
Without CAN bus termination system is not working.
CAN bus termination is done by putting the jumpers to the places on the boards on which the termination is
done (LC100-C, LC100-E, LC100-I, LC100-P or M)
LC100-K bord has implemented CAN bus termination.
Correctly terminated CAN bus means that the termination is done on both ends of the CAN communication
bus. On simplex elevators termination is done on the LC100-K (integrated) and on the LC100-C board for CAN 1
communication and for the landing calls (CAN2) termination is done on the LC100-C bord and the farthest landing call
module (LC100-P or M).
When the CAN bus is correctly terminated resistance betwen CAN_L and CAN_H line has to be cca
68(betwen pins XC1.2 and XC1.3)
Examples of correctly terminated CAN bus:
