Setting the address offset
Each MOBILE device has one address for the Public CAN and three addresses for the
Private CAN. An address consists of the basic address and the address offset (address =
basic a address offset).
ƒ
Default setting of the address offset: 13 (ID pins are not wired)
ƒ
Default setting of the basic address for Public−CAN: 234
ƒ
Default setting of the basic addresses Private−CAN:
– AppC: 32
– MC (channel 1): 1
– MC (channel 2): 64
The address offset is defined by wiring ID−Pin1...ID−Pin4 to X31. Thanks to the
combinations, 14 different address offsets are possible which means that up to 14 MOBILE
devices can be operated at a CAN bus.
