HLS-442 − Electrical Inter face

CAN Bus Interface

This section describes the CAN bus interface that is available in

some variants of HLS-442.

Physical Interface

The physical interface is two-wire balanced, non-terminated. It

is a high speed CAN interface (ISO 11898-2) with bus bit rate of

125, 250 or 500 kBit/s, depending on the variant of HLS-442.

Bus Identification

Each sensor and the control unit are identified on the bus by

the CAN identity, CAN ID. The CAN ID is transmitted in the CAN

data frame arbitration field. For the sensors the CAN ID is

determined by the configuration of the power supply feeds,

UB0 (pin 3), UB1 (pin 4) and UB2 (pin 5). The table below defines

the sensor’s CAN ID, VB denotes a power input connected to

supply voltage level. Addresses are given in hexadecimal

numbers and denoted with a leading “0x”.
