DEVICE CONFIGURATION

Settings

Device hostname CAN bitrate Wi‑Fi network Wi‑Fi password

CAN acknowledgementAllows hardware ACK and CAN error signalling. Application frame transmission remains disabled.

LISTEN ONLY

ACK mode participates electrically on the CAN bus. It is temporary and always returns to listen-only after a restart.

Seplos inverter heartbeatActively sends only standard frame 0x305 with eight zero bytes once per second.

OFF

Heartbeat mode actively transmits and also provides hardware ACK. It is temporary, single-shot, and always disabled after a restart.

CHECKING

Restart deviceSafely restart CAN Watch. Active CAN participation returns to listen-only.
