Introducing Automatic Baud Rate Detection in Serial Tap Pro
Serial Tap Pro just learned a new trick: Automatic Baud Rate Detection (ABR). And it’s not the usual pattern-based ABR you find elsewhere — this one actually works on any data.
Why Do You Need ABR?
Imagine troubleshooting a legacy system where devices communicate over RS485 or some other flavor of serial comms. You want to see the data being exchanged — it might hold the key to understanding why the system isn’t behaving as intended. But first, you need to figure out the baud rate and other serial parameters. Of course, you have no datasheets, and Google sends you to abandoned websites from the 90s or unanswered posts on Chinese forums. Bummer.
(And even with a datasheet, it’s not always easy. Devices may use non-standard configurations, datasheets may list ranges of possible parameters, or they may contain errors.)
This is where Serial Tap Pro steps in. Simply connect it to the link, and it will quickly tell you the exact serial parameters your devices are using — no guesswork required.
What Makes our ABR Stand out?
Works With ANY Data
Other ABR-enabled products rely on specific byte patterns, but how would you know in advance what bytes the devices send? Isn’t that why you need a sniffer in the first place? Our ABR works on a few random bytes passing through.
Instant and Non-Intrusive
Detected serial parameters instantly appear in the Information Pane. The engine is entirely non-intrusive — it simply offers a hint, and it’s up to you whether to adjust the Tap settings.
Works Even When TX and RX Baud Rates Don’t Match
Tibbo ABR detects mismatched baud rates between devices — a very common cause of serial communication issues. With Serial Tap Pro, you’ll spot such problems immediately, saving yourself hours of frustration.
Stuck Debugging Serial Communications? Serial Tap Pro to the Rescue!
At launch this past summer, Serial Tap Pro was already the most advanced serial sniffer on the market, featuring:
- All-in-one interface support (RS232, RS422, RS485, TTL UART)
- Full galvanic isolation across all serial lines
- High baud rates (up to 2.5Mbps)
- Guaranteed chronological capturing accuracy with microsecond precision
- 9-bit data decoding
- Automatic data direction detection for half-duplex RS485 buses
- Injection of packets and control line changes
These and other features make Serial Tap Pro the ultimate tool for troubleshooting UART-based links. It provides unmatched capabilities for capturing, analyzing, and generating serial packets, with the new automatic baud rate detector being a sweet cherry on top.
Detailed documentation for all features of Serial Tap Pro is available in the IO Ninja User Manual, making setup a breeze.
