Manuals & user guides

Official manuals and clean English re-writes for every GSM gate opener module supported by [GateOpener](https://gate-opener.app/). Each page has the default password, the full SMS command table, a wiring diagram, the original manufacturer PDF, and a step-by-step setup walkthrough.

## Looking for the RTU5024 user manual?

The original manufacturer PDF and a readable English / Deutsch web version is on the [RTU5024 manual page](https://gate-opener.app/manuals/rtu5024/). That page also covers the 4G LTE variant (sometimes called RTU5024 V2) and is the same hardware sold as *BLIIoT*, *King Pigeon*, and *Huobei*.

## Don't see your module?

Most GSM gate openers sold worldwide use one of two protocols: **RTU5024** (roughly 70% of the market — King Pigeon, BLIIoT, Huobei, and dozens of rebrands) or **Callny** (around 15-20% — G202 PLUS, G203, Daniu, LPSECURITY). If your module responds to the SMS command syntax on either of those manual pages, the commands work. Otherwise, [submit a hardware request](https://gate-opener.app/request-hardware/) with a copy of your manual and I will add it.
