Io LD and Io LA Installation and Operation Manual — Video and FireWire
Typical Analog System with Io
LA
System interconnections for a system with analog A/V sources are shown on the
previous page. Your system may differ depending on VTRs, audio monitoring, and
video monitoring.
1. If desired, connect your house reference sync to the Io Ref Loop connector
(BNC). The second Io
LA
Ref Loop connector can be connected to your VTR or
terminated with a 75 ohm terminator (also optional).
2. Connect a Video Monitor to the Io
LA
Composite Analog Video Out BNC
connector, or instead connect a monitor via the S-Video Out connector (4-pin
mini-DIN).
3. Connect a 9-pin DB9 machine control cable between your VTR’s RS-422
control port and the Io
LA
RS-422 (machine control) connector.
4. Connect Component Video cables between Io
LA
and your analog VTR (BVW-
75 etc.): one from Io
LA
Component Video In BNCs (3) to the VTR Component
Video Out BNCs (3), and one from Io
LA
Component Video Out BNCs (3) to the
VTR Component Video In BNCs (3).
5. Using the supplied Io
LA
breakout cable, connect audio cables between Io
LA
and
your analog VTR (BVW-75 etc.). Connect the four channels of Io
LA
Balanced
Audio Out to the VTR’s four Audio Inputs (A1/A2/A3/A4). Next, connect the
four channels of Io
LA
Balanced Audio In to the VTR’s four Audio Outputs (A1/
A2/A3/A4). Use balanced audio cables for all connections; these will have XLR
connectors on both ends (male on the output side/female on the inputs).
6. Connect the Io
LA
FireWire connector to your host Power Mac or Xserve
FireWire port using a standard IEEE 1394a cable.
Video and FireWire
FireWire is a cross-platform implementation of the high-speed serial data bus defined
by IEEE Standard 1394-1995. It can be used to move large amounts of data between
computers and peripheral devices—any type of data. It features simplified cabling, hot
swapping, and transfer speeds of up to 400 megabits per second (FireWire 400). A
new 800 megabit per second implementation (FireWire 800) is also available on many
current Apple computers. AJA has codeveloped the Io family of products with Apple
to use FireWire for transferring 10-bit uncompressed video and 24-bit audio to and
from an Apple Power Mac or Xserve.
Major manufacturers of multimedia devices have been adopting the
FireWire technology and it can be found in a variety of professional
and consumer digital products—including digital camcorders, digital
video tape recorders, digital video disks, set-top boxes, and music
systems.
Apple's FireWire technology was honored by the Academy of
Television Arts & Sciences, receiving a 2001 Primetime Emmy Engineering Award for
FireWire's impact on the television industry.
