UART Trigger (Universal Asynchronous Receiver/Transmitter)

UART trigger supports Start / End / Break / Parity Error / Stop Bit Error, plus Clause Trigger patterns on Tx / Rx.

Wrong Baud Rate or framing settings prevent triggers. TravelBus offers a dedicated UART port. See Settings and Clause Trigger.

UART Trigger (LA)

UART Trigger TravelBus

UART Trigger (TravelBus; extra channel source)
  • Channel: Dedicated UART port or LA Tx / Rx channels. Default is the LA port.
  • Channel Input: Input polarity option. Default: index 0.
  • Baud Rate (Data Rate): Default: 9600.
  • Data Bits: Default: 8.
  • Parity: Default: index 0 (None).
  • Stop Bits: Default: index 0 (1 Stop).
  • Simple Trigger: Start / End / Break / Parity Error / Stop Bit Error. Default: all cleared.
  • Clause Trigger: See Clause Trigger.
  • State: Enter Data as a data pattern; XXh = Don't care. Up to 16 bytes; use Bypass with an offset when needed.
    • Data pattern: Default XXh (width follows Data Bits); size Default 8 frames; Hex; source Default Tx.
    • Bypass: Default cleared, offset 0.
