Connect a CAN bus device

Read frames from a CAN bus through a gateway's CAN transceiver.

Protocol: can · Requires: a gateway

Connection fields:

Field Meaning
txPin / rxPin Gateway pins to the CAN transceiver
baudRate 125000, 250000, 500000, or 1000000
sampleIntervalMs How often to sample (ms)

Steps

  1. Connect the transceiver to the gateway's TX/RX pins and the CAN-H/CAN-L lines to the bus.
  2. Add a device with protocol can, choose the gateway, and match the bus baud rate.
  3. Map decoded signals to tags.

can/fault events usually mean a baud-rate mismatch or wiring/termination issue.

Device parameters (tags) explained
Tags are the named measurements a device reports — what widgets bind to.
How device online/offline status works
A device is online if we've seen a message in the last 90 seconds.
Alert thresholds (and the yellow dot)
Set a high/low range on a tag; the device dot turns yellow when a reading goes out of range.
