4-pin FireWire connector with the Helix Board and Firefly?
Although all of our units feature a 6-pin FireWire connection, users are able to use a 4-pin adapter as all data is transfered in these pins alone. The additional 2 pins are for bus powering units, which none of the Helix Boards support and,
out of all the Firefly units, only the Firefly 302 Plus is able to support. It should be noted, however, that most 4-pin connectors are found on notebook computers and - although majority of FireWire cards are compatible - it cannot be guaranteed that your computers onboard FireWire port will be compatible with the Helix Board or Firefly.
