Set the baud rate by sending the following message:
Item Value
COB-ID 0x7E5
Length 3
Data 0
0x13
(cs=19 for configure bit timing parameters)
Data 1
0x00
(switches to waiting state)
Data 2
Index
(select baudrate index per Table 32)
Table 16: LSS baud rate indices
Index
Bit Rate
0
1 Mbit/s
1
800 kbit/s
2
500 kbit/s
3
250 kbit/s
4
125 kbit/s (default)
5
reserved
(100 kbit/s)
6
50 kbit/s
7
20 kbit/s
8
10 kbit/s
The module will send the following response (any other response is a failure):
Item Value
COB-ID 0x7E4
Length 3
Data 0
0x13
(cs=19 for configure bit timing parameters)
Data 1
0x00
Data 2
0x00
Activate bit timing parameters by sending the following message:
Item Value
COB-ID 0x7E5
Length 3
Data 0
0x15
(cs=19 for activate bit timing parameters)
Data 1
<delay_lsb>
Data 2
<delay_msb>
The delay individually defines the duration of the two periods of time to wait until the bit timing
parameters switch is done (first period) and before transmitting any CAN message with the new bit
timing parameters after performing the switch (second period). The time unit of switch delay is 1 ms.
