Case Studies

Unibrain, having huge experience in Firewire technology has tested and recommends the following basic applications and configurations for the GOF Repeater800™

Case A : Connection of two (2) hosts

Connect one (1) PC or Macintosh, having 1394a or 1394b interface, to an GOF Repeater800™ via one 9-6 or 9-9 cable. Connect the two GOF Repeater800™ via Glass Optical Fiber Cable (up to 550 meters). Connect the second repeater via one 9-6 or 9-9 cable to the other PC or Macintosh.

Case B : 1394a/b cameras

Connect one (1) PC or Macintosh, having 1394a or 1394b interface, to an GOF Repeater800™ via one 9-6 or 9-9 cable. Connect the two GOFRepeater800™ via Glass Optical Fiber Cable (up to 550 meters). Connect the second repeater via 9-6 or 9-9 cables to 1394a or 1394b cameras. NOTE: In this case it is mandatory the usage of the 12V power supply in order to provide current to the repeater that is connected to the cameras.

Case C : External SBP-2 HDD

Connect one (1) PC or Macintosh, having 1394a or 1394b interface, to an GOF Repeater800™ via one 9-6 or 9-9 cable. Connect the two GOF Repeater800™ via Glass Optical Fiber Cable (up to 550 meters). Connect the second repeater via 9-6 or 9-9 cables to 1394a or 1394b external HDD. NOTE: In this case it is optional the usage of the 12V power supply in order to provide current to the repeater that is connected to the HDD, provided that the HDD receives external power.

Case D : DV camcorder

Connect one (1) PC or Macintosh, having 1394a or 1394b interface, to an GOF Repeater800™ via one 9-6 or 9-9 cable. Connect the two GOF Repeater800™ via Glass Optical Fiber Cable (up to 550 meters). Connect the second repeater via 9-6 or 9-9 cables to the DV camcorder. NOTE: In this case it is mandatory the usage of the 12V power supply in order to provide current to the repeater that is connected to the DV camcorder.
