FireWire 6-pin connector

The six-contact FireWire form has a larger housing than the four-contact form and includes a power-carrying interface.

Also called IEEE 1394 6 pin FireWire 400 connector

Identify the generation, then verify the power arrangement.

Look for

Compare the beveled end of the shell and six-contact arrangement; do not use trial insertion to identify it.

Application notes / Legacy data / P106

Does the powered form guarantee a working connection?

FIELD NOTES 04

The six-pin interface includes DC power as well as data, unlike the four-pin form. Actual power availability and software support still depend on the equipment.

Identify first

Read the part and the device.

The larger beveled shell distinguishes the form; it is not a current or driver certificate.

Still unresolved

Keep this requirement open.

Unknown port power, device demand and operating-system support stay open.

Explicit source exclusion · named example only

Will bus power be carried through the four-pin interface?

No: the four-contact form carries data without bus power.

Boundary. This does not determine which external supply, host or software the peripheral needs.

Next check. Follow the peripheral’s approved power and connection instructions.

S088 · C105B (private workspace) · C106B (private workspace)

Before choosing an adapter or reader

  1. Identify the host and peripheral models.
  2. Confirm the required power arrangement in their manuals.
  3. Check data support separately from bus-power availability.

Read the view

Beveled end on the right of the shell

The beveled end points right in the sketch. No front-to-rear pin transformation is supplied.

About the marks: The dot arrangement is not an actual contact map.

What it cannot establish: Use the exact device and cable documentation for power and supported operation, not this outline.

Enlargement changes display size only. It does not reveal measured geometry, a pin assignment or an approved mating combination.
