The following is a documentation for the unmanaged switch marked as SWTG018AS-A V2.0. It is e.g. sold under the Ampcom brand, but no branh-markings are found on the device.

The original software is running UART on 9600 baud rate.

Using a SOIC clamp in-board is the only method for initial installation.

The board has a single flash chips BS with 4M-bit size. The front switch, switches between the two flash chips. These can be programed independently by using said switch - so it is e.g. possible to run the original and new firmware in parallel.
