Io HD Installation and Operation Manual — Genlock and Your System
2. Connect a Video Monitor to the Io HD 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 RS422
machine control port and the Io HD
RS422 connector.
4. Connect Component Video cables between Io HD and your analog VTR
(BVW-75 etc.): one from Io HD
Component Video In BNCs (3) to the VTR
Component Video Out BNCs (3), and one from Io HD Component Video Out
BNCs (3) to the VTR Component Video In BNCs (3).
5. Connect audio cables between Io HD and your analog VTR (BVW-75 etc.):
connect the four channels of Io HD
Balanced Audio Out to the VTR’s four
Audio Inputs (A1/A2/A3/A4). Next, connect the four channels of Io HD
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 HD FireWire 800 connector to your host Mac or Xserve
FireWire 800 port using the standard IEEE 1394b cable provided. A second
alternate cable is also provided that bridges between FireWire 800-style
connectors and FireWire 400-style connectors. (Observe the same notes
previously given under “Typical Digital System” for FireWire drives and the
use of other FireWire devices when working with Io HD.)
Genlock and Your System
For video stability and proper system operation, it’s always best to genlock all
equipment to house sync (also known as reference). Although genlock is not
absolutely required for Io HD or your system, better quality and repeatable operation
will be experienced by doing so. Usually, this means using a black burst generator
(standard definition) or Tri-level sync generator (high definition) output looped
through the system. On the Io HD, house sync is connected to the “Ref ” input BNC
(Reference Video).
Understanding Io HD and FireWire 800
FireWire 800 is a cross-platform implementation of the high-speed serial data bus
defined by IEEE Standard 1394b-2002. 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 800 megabits per second. AJA has
codeveloped Io HD with Apple to use FireWire to transfer 10-bit uncompressed SD
video, ProRes 422 (SD and HD) and ProRes 422 HQ HD video and 24-bit audio to
and from a Mac Pro, MacBook Pro, or Xserve.
Most people associate FireWire technology with DV or HDV. The AJA
Video Io HD does not use FireWire like a DV camcorder——rather Io
HD uses the impressive bandwidth of FireWire as a conduit to send A/
V data to and from the host Mac or Xserve, regardless of whether it’s
uncompressed SD or Apple ProRes 422.
Note: When possible, use FireWire 800 ports on the host Mac when
connecting Io HD.
