Bootloader Version 3 / 4 Up to now, all Netzers supplied had the Bootloader in version 2. This Bootloader accepted intel hex files via TFTP standard. Instead of intel hex files, the new versions of the Bootloader expects (encoded) binary files with a proprietary structure. Those Bootloader are particularly for professional use. Bootloader 3 is used for firmware release 1.4, Bootloader 4 is used for release 1.5.

commandinterface

Anonymous (anonymous@undisclosed.example.com) — 2025-06-11T18:42:14+00:00

Command interface The command interface can be used for accessing Netzer with client programs. Functional principle The command interface is message based, i.e. defines the format of the exchanged messages between Netzer and a client program. The communication channel is mostly independent from the message. Hence, multiple channels are implemented from where the command interface can be used. Which channels are implemented depends on the Netzer firmware version. Possible channels are the

230 V Dimmer IO projectuploaded The Netzer supports the direct connection of phase dimmers. So it is possible to control high voltage loads like bulbs via Ethernet resp. Intranet/Internet. Be careful when experimenting with 230 V. There is danger to life! A phase switching mechanism is described here that is for example built up by a thyristor. For this switching mechanism, the important feature of the thyristor is that in zero crossing it deletes from mains voltage itself, i.e. switches off.

Impulse handling with Netzer IO Netzer is able to generate and capture signals at IO3 and SPI_INT. The image shows the structure of the impulse generator/capture. The impulse module is divided into two modes, the unsynchronized mode and the IO0 synchronized mode. Both, IO3 and SPI_INT, can either work in unsynchronized or in IO0 synchronized mode.

SPI Master Ethernet Gateway In this mode the Ethernet gateway Netzer can directly communicate with SPI devices like memories or LCDs. One or more slaves are connected to Netzers SPI interface (3 wire). The Netzer acts as SPI master. SPI normally needs one chip select per slave. Sometimes more wires are necessary in order to control a slave. For example a reset signal.

WebSocket WebSocket is a protocol for bidirectional communication between a web application and a server via a TCP connection. Netzer uses WebSocket as a channel for the command interface. Why WebSocket? In normal HTTP a client (i.e. the browser) sends a request to a server. After some processing time the server responses to the client. This is one way, the server can not serve files or data by itself without been requested before. This is a disadvantage i.e. if data must be asynchronously r…
