The Cardbus Interface
For the Hammerfall DSP I/O-boxes Digiface, Multiface and RPM, RME have developed a world-exclusive PCMCIA type II card in Zero wait state CardBus Busmaster technology. With up to 130 MB/s transfer rate in both directions the same basic performance is provided on a notebook as a PCI card would offer on a desktop computer. Additionally the card offers highest compatibility by being 100% Plug & Play compatible under Windows and Mac OS, and being able to share interrupts. The card itself will only use one interrupt (IRQ) for all functions (audio/MIDI.)
The connection between CardBus card and I/O-box is established using ordinary FireWire cable (6-pin IEEE 1394a). The data transfer does not use FireWire protocol, but a proprietary bus protocol by RME. The supplied cable has a length of 4 m (12 ft.). The CardBus card does not provide power to the attached I/O-box. Therefore a compact and light-weight hi-tech switch-mode power supply is included.
The CardBus shown above ships since mid 2005. In case two HDSP CardBus shall be used in one laptop, the lower card must be a flat version, which is also available. It uses a special cable (15-pin Closed LAN to 6-pin IEEE1394a, included), with a length of 4 meters (12 ft.). The flat card is 100% identical and compatible, but does not offer the Secure BIOS technology of the upper version.
