The Lens Link, LDT-RX1 and DCS Bridge units can all share the same firmware from 2.3.0 onwards.
Further information on how to apply this firmware can be found here.
Unlisted - Contact DCS if required.
If the update does not apply, please use this 'Quickfix' file to remove the currently installed firmware. This ensures the main update file can then be applied to the unit without any issues. This only affects Mac devices running firmware earlier than 2.3.0, as the error no longer occurs from 2.3.0 onwards.
