Glyph gt060br-1500 Information Guide

Q: What’s FireWire 800?

A high-speed version of IEEE-1394b FireWire.  FireWire 800 uses the new IEEE-1394b “Beta” protocol (data-transfer
language) to improve performance and efficiency.

Q: What are the differences between FireWire 800 and FireWire 400?

Speed and Protocol. a) FireWire 800 has a max transfer rate of 800 Mb/sec (about 100 MB/sec peak). FireWire 400 has a
max transfer rate of 400 Mb/sec (about 50 MB/sec peak). The higher bus speed helps with things like large file copies and
RAID, where FireWire 400 bus speed can be a limiting factor. B) FireWire 800 uses IEEE-1394b “Beta” protocol; FireWire
400 uses IEEE-1394a “DS” protocol.

Q: What’s Beta?

A FireWire protocol (data transfer language) defined in IEEE-1394b.  It is much faster and more efficient than the “DS”
protocol used in IEEE-1394a (FireWire 400). Beta is what permits the higher speed and performance of FireWire 800.  The
Beta protocol can only use the new 9-pin connectors.

Q: What’s Bilingual mean?

“Bilingual” refers to a port that can use either the new “Beta” protocol or the old “DS” protocol. The FireWire 800 ports on
the GT 060BR are Bilingual, meaning that they adjust their protocol to match whatever they’re connected to. A Bilingual
port connected to another FireWire 800 port will use the Beta protocol and run at FireWire 800 speed;  but if it’s connected to
a FireWire 400 port, it will use the DS protocol, and therefore will be limited to S400 speed.

“Bilingual” also refers to a cable that connects a Bilingual S800 9-pin port to a FireWire 400 6-pin or 4-pin port, for
backward-compatibility.

Q: Does Glyph sell Bilingual Cables?

Yes, you can purchase 9-pin to 6-pin and 9-pin to 4-pin cables from an authorized Glyph dealer.

Q: Does Glyph sell an 800 PCI card?

Yes. The Glyph FireWire 800 PCI Card is available from an authorized Glyph dealer. The card has three Bilingual ports, and
is compatible with Mac and PC. It requires Mac OS 10.2.5 or later, or Windows 2000/XP. There are no drivers required for
the card to work on the Mac or Windows operating systems.

Q: My Windows computer doesn’t show the drive in My Computer. What’s up?

The default format on the GT 060BR is for the Macintosh, and Windows doesn’t recognize it. Once you have connected the
GT 060BR to your Windows PC, you have to re-initialize it for use with Windows.  For Windows XP and 2000, that’s going
to be NTFS format; for Win98/SE, that will be FAT32 format. Instructions for re-initializing your drive are on your Glyph
documentation CD and on the Glyph website.
