Product overview

How MultiNode network works

• One device is the master; all others are regular nodes (leaf or repeater).
• Regular nodes communicate with the master over PLC.
• Peer‑to‑peer communication between regular nodes is isolated, i.e., regular nodes can only communicate with the master.
• The web interface of the master node can be used to setup and configure the network.

Product documentation

MultiNode LAN 4TE includes the following supporting documents:

• Safety & service flyer: General safety and service information

• User manual (this document)

Migrating older firmware versions

Update to the latest firmware

This user manual assumes your MultiNode LAN 4TEs are on the latest firmware (7.16.7.35 • 2025-11-13). To identify the firmware version of your device, connect a laptop to the device via Ethernet cable and check the firmware version on the device's web interface.

If your MultiNode LAN 4TEs run a firmware version older than 7.16.5.31, we offer three ways to update them to the latest firmware:

1. Update individually by using the built-in web interface of each device; see instructions.
2. Update all devices at once via the Firmware Migrator tool available on the product website.
3. Let us update the devices for you: If your devices have internet access, send their serial numbers to support@devolo.de. Our support team will initiate the update remotely.

Key MultiNode terms

PLC (Powerline Communication): A technology that transmits data signals over existing electrical power lines by modulating high-frequency carrier waves onto the low-frequency AC power signal.

MultiNode LAN network: A network built with MultiNode devices.

Node: A device that's part of the MultiNode network.

Master node: The main controller of the MultiNode network. Only one node in the network can be the master.

Regular node: Any node that can be managed by the master node. By default, nodes are configured as regular nodes.

Seed: A number (0–59) that identifies and separates PLC networks.

Safety and compliance

Intended use

MultiNode LAN 4TE is a fixed-installation device of overvoltage category 3. It communicates via powerline communication (PLC) over low-voltage mains. The unit is designed for water-protected environments and must be mounted on a DIN-rail within touch-protected or access-controlled areas.

Use the MultiNode LAN 4TE as instructed to prevent damage and injury.

Safety

Read and understand all safety and operating instructions before first use.
