CAN Stream Information
The tables below describe how the data in CAN streams on the PDM are transmitted and received on the Link Razor PDM. This information is useful when interacting with a device that does not have built in Link Razor PDM functionality.
The structure used is based on the CAN Channel Mode. All data is sent/received with the most significant byte first.
CAN Function
Byte 0 (Unsigned) | Byte 1 (Unsigned) | Byte 2 & 3 (Unsigned) | Byte 4 & 5 (Unsigned x100) | Byte 6 & 7 |
