Cabling the System
Typical System This figure shows typical system interconnections for a system with digital A/V sources.
Your system may differ depending on VTRs, audio monitoring, and video monitoring.
1. If desired, connect your house reference sync to the Io Express Ref/LTC connector
(BNC). The second Io Express Ref Loop connector (if used in Pass through mode)
can be connected to the VTR or terminated with a 75-ohm terminator. If instead
using LTC timecode input, connect to the Ref/LTC input.
2. Connect an HDMI Video Monitor to the Io Express HDMI Out connector. Or instead,
use the Component Analog Video Out BNC connectors to go to an analog monitor.
3. Connect a 9-pin DE-9 machine control cable between your VTR’s RS422 control
port and the Io Express RS-422 machine control connector.
4. Connect two SDI cables between Io Express and your digital VTR (Digital Betacam
etc.): one from Io Express SDI In to the VTR SDI Out, and one from Io Express SDI Out
to the VTR SDI In. The Io Express SDI connections have embedded audio so the
VTR must be configured accordingly.
5. Use the two RCA-style unbalanced stereo output jacks for audio monitoring
output.
