V430 WebSocket Barcode Node

Node-RED node for streaming barcode reads from an Omron V430 over WebSocket.

Installation

Install with npm:

npm install v430-barcode

Restart Node-RED and add V430 sBarcode from the omron category.

Behavior

• Connects to the fixed V430 endpoint
• Decodes text WebSocket frames and binary MessagePack frames.
• Sends the decoded barcode on output 1 and the complete event metadata on output 2.
• Starts the WebSocket client only when Enabled is selected.

Configuration

| Field | Description | | --- | --- | | Name | Optional display name for the node. | | Host / IP | Hostname or IP address of the V430. | | Enabled | Opens the WebSocket connection when selected. | | Timeout ms | WebSocket handshake timeout. | | Reconnect ms | Delay before reconnecting after a closed connection. |

Example Flow

Import examples/v430-barcode-example.json into Node-RED, set the V430 host address, then deploy. The flow sends the barcode and metadata outputs to separate Debug sidebar entries.

Outputs

Output 1 sends the barcode read:

{
  "topic": "v430/barcode",
  "payload": {
    "barcode": "0041199006794",
    "symbology": "EAN13",
    "host": "192.168.250.2",
    "port": 50502,
    "path": "/",
    "cycle_id": "0x000000e6",
    "read_time_ms": 86,
    "cycle_time_ms": 485,
    "received_at": "2026-07-06T14:30:00.000Z"
  }
}

Output 2 sends the complete event metadata under msg.payload. Output 1 also includes the decoded frame at msg.raw_event.

Local Development

1. Run npm install in this folder.
2. Run npm test.
3. In your Node-RED user directory, run npm install <path-to-this-folder>.
4. Restart Node-RED.

Publishing

This package includes the Node-RED manifest, public publish configuration, README, license, and runtime/editor files required for palette discovery. Authenticate to npm, then run:

npm publish

After publishing, install the package from npm in the Node-RED user directory. Palette availability through catalog search depends on Node-RED catalog indexing of the package name.
