Bulkheads Overview

Bulkheads represent physical connector interfaces that pass signals through a barrier (such as a fuselage wall). In SkyWire Studio, a bulkhead is drawn as two rectangular plugs — one on the left and one on the right — connected by shared pin pairs.

Structure​

  • Left and right plugs — two rectangular connector halves drawn side by side.
  • Pin pairs — each pair consists of a left pin and a right pin sharing the same label. Wires connect to each side independently.
  • Label — the bulkhead name (e.g., "J1") displayed above the connector.

Creating a Bulkhead​

  1. Open the Bulkhead tool from the toolbar.
  2. Enter a Label for the bulkhead (e.g., "J1", "Bulkhead A").
  3. Configure Pin Ranges to define your pin labels:
    • Lowercase — a range like "a" to "z"
    • Uppercase — a range like "A" to "Z"
    • Numeric — a range like "1" to "10"
  4. You can combine multiple range types. A live preview shows the generated pin labels and total count.
  5. Click Save to create the bulkhead.

The bulkhead appears on the canvas with all pin pairs arranged vertically. If no custom labels are provided, pins default to a numeric sequence (1, 2, 3...).

tip

You can define up to 78 pins per bulkhead.

Connecting Wires​

Each pin on a bulkhead has a connection point. To wire a bulkhead:

  1. Activate the QuickConnect tool (or press Ctrl+Q).
  2. Click on a bulkhead pin to start a wire.
  3. Click on the destination pin (on an LRU, another bulkhead, or a symbol) to complete the connection.

Wires automatically update when you move or resize the bulkhead.
