AnalogX CAN bus API
Overview
The CAN bus API provides the configuration and control interface for AnalogX
CAN Messages
CAN base ID
CAN base ID is 0xE4600 (935424)
Adjusting Base ID
The base address is determined by the state of the ADR1 and ADR2 jumpers. By default, the jumpers are bridged; cutting the jumper ADR1 will add 256 to the base ID, and cutting jumper ADR2 will add 512 to the base ID.
The combination of jumper settings will allow up to 4 AnalogX units to coexist on the same CAN bus.
| ADR2 | ADR1 | Address |
|---|---|---|
| Default | Default | 0xE4600 (935424) |
| Default | Cut | 0xE4700 (935680) |
| Cut | Default | 0xE4800 (935936) |
| Cut | Cut | 0xE4900 (936192) |
CAN Baud rate
500K and 1MB rates are supported.
500K is enabled by default; cut the jumper labeled BAUD on the bottom of AnalogX to enable 1MB rate.
