CAN Bus Bandwidth Limit
The total available CAN bandwidth on a single CAN bus is 1 Mbit/sec.
The bandwidth used by the total of all devices on a particular CAN bus must
not exceed approximately 90% of this value (900000 bits/second)
If the total bandwidth required exceeds this specification then some devices
should be connected to the second CAN bus.
Note: Dash Manager will warn if the bandwidth is likely to be exceeded.
E888
Device on first CAN Address: Bandwidth = 145000 (bits/sec)
Device on second CAN Address: Bandwidth = 55000 (bits/sec)
Other Devices
Device Bandwidth
BR2, SLM , PLM Negligible
SDL, ADL2, MDD, M800 ECU TBD
