**Modbus RTU**.

## 1. Benötigte Hardware

- Waveshare 8-Channel Relay Module (RS485)
- USB↔RS485-Adapter auf Hub-Seite
- 12-V-DC-Versorgung + Buskabel (A/B)

## 2. RS485-Anschluss

A↔A, B↔B, gemeinsame Masse, **120 Ω** am Busende.
12 V DC an die Klemmen VCC/GND des Moduls.

## 3. Modbus-Adressierung

Standardadresse: **1**. Einstellbar über das Waveshare-Dienstprogramm oder per
Modbus-Befehl zur Adressänderung.

Parameter: **9600 bps, 8N1**.

## 4. Hinzufügen in PowerSync
