Hammerfall HDSP - Laptop CardBus Card

The CardBus Interface

For the Hammerfall DSP System RME 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 MacOS, 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(Closed LAN to IEEE 1394). The data transfer does not use Firewire protocol, but our own proprietary bus protocol. The supplied cable is 4.5 m (15 ft.) long, a cable length up to 15 m (48 ft.) has been successfully tested. A specially designed Repeater can be used to reach cable lengths of up to 30 m (100 ft). The CardBus card does not provide power to the attached I/O-box. Therefore a hi-tech switching power supply is included.
