Fixed-Code Decoders
The 16 fixed-code remote protocols Echo decodes, plus a general decoder for unnamed remotes.
Nesta página
Fixed-code remotes send the same code every time. Echo recognises 16 named fixed-code protocols, plus a general decoder for cheap remotes that don't match a named one. Once captured, these remotes can be identified, and in several cases re-created and replayed.
What Echo decodes
- EV1527
- Common learning-code remotes and sensors. Shows a fixed device address plus a status/button nibble.
- PT2262
- Classic DIP-switch encoder, electrically similar to EV1527. Shows the same address + data-nibble split.
- Holtek (HT6P20B/D)
- Holtek-based remotes, 28-bit code. Shows address and button/function bits.
- General pulse-distance
- Fallback for cheap OOK remotes and sensors that don't match a named protocol, still shows timing and raw bits.
- CAME
- CAME gate remotes, distinguished from Nice FLO by pulse timing. Shows the DIP/fixed code.
- NICE FLO
- Nice FLO gate remotes. Shows the DIP/fixed code.
- Chamberlain
- Chamberlain "Security" trinary-DIP remotes. Shows the DIP code; can be re-created and replayed.
- Linear MegaCode
- 24-bit Linear MegaCode remotes. Shows the fixed code.
- Linear Delta 3
- 8-bit Linear Delta 3 remotes. Shows the fixed code; can be re-created and replayed.
- Hörmann (HSM)
- 44-bit Hörmann garage remotes. Shows the fixed code.
- Clemsa
- 18-bit Clemsa / Berner / Elka / Tedsen remotes. Shows the fixed code.
- Mastercode
- 36-bit Mastercode gate remotes. Shows the fixed code.
- Marantec
- 24-bit Marantec garage remotes, pulse-position encoded. Shows the fixed code.
- Ansonic
- 12-bit Ansonic remotes. Shows the fixed code; can be re-created and replayed.
- Magellan
- 32-bit Paradox / Magellan alarm sensors, CRC-checked. Shows the sensor's fixed code.
- Nexa
- 32-bit Nexa / Intertechno-V3 smart-home remotes, Manchester-encoded. Shows the fixed code.
- Dooya
- 40-bit Dooya blind and shade motor remotes. Shows the fixed code.
This goes well beyond the EV1527 / PT2262 / CAME / NICE FLO / Holtek / Chamberlain families usually named for tools like this, Hörmann, Clemsa, Nexa, Dooya, Magellan, Mastercode and Marantec are all decoded too.
What you actually see decoded
Every fixed-code result boils down to the same handful of plain-language fields, what varies is which ones a given protocol carries:
- Fixed address / DIP code
- The unchanging identifier for that specific remote or gate opener, present on every protocol above
- Button / function bits
- Which button was pressed, where the protocol encodes more than one function (EV1527, PT2262, Holtek, Marantec)
- Raw bit pattern + timing
- Shown for any signal, useful for the general pulse-distance fallback when nothing named matches
Identifying similar remotes
Some remotes look alike and are told apart by their timing rather than their content, EV1527 and PT2262, and CAME and NICE FLO, are two such pairs. Echo handles the distinction for you and reports the right one.
Re-creating and replaying
Several of the named remotes can be re-created and replayed by Echo (Chamberlain, Ansonic and Linear Delta 3 among them). Two more tools help with fixed-code research:
- Brute-force, sweeps the short set of possible DIP-switch codes.
- Fuzzer, sends varied test signals.
