Chapter 4: System Installation and Connections
Multi-Purpose Breakout Cable and Connections
The optional X75OPTCAB-MULTI breakout cable connects to the
high-density DB-26M connector on the back of the unit labelled
Multi I/O. Input connections include GPI 1 and GPI 2. The cable
provides the following output connections:
• S-video (Y/C)
• RGB (Blue, Green, Red)
• Aux Composite or Sync
• GPI 1 and GPI 2
• SDTV audio delay
• HDTV audio delay.
For pinout descriptions of this cable, see “Multi I/O Cable
(X75OPTCAB-MULTI)” on page 203.
S-Video (Y/C) Output
This four-pin mini-DIN connector on the Multi I/O breakout cable
provides processed, synchronized/time base-corrected S-video (Y/C)
output.
RGB (Blue, Green, Red) Video Output
These Red, Green, Blue, and Sync BNC connectors provide processed,
synchronized/time base-corrected RGB(S) (RGB with auxiliary sync)
video output. You can turn all three RGB channels’ sync signals on or
off independently. If RGB without auxiliary sync is sufficient, reassign
the Sync/Composite connection as an auxiliary composite output.
Synchronized Composite Output
As described above, you can reassign the sync composite connection on
the Multi I/O breakout cable. This capability is set by the Aux
Sync/Comp option in the Video Setup menu.
GPI 1 and GPI 2 Input/Output
To use a GPI-based external controller as a trigger for internal functions
of the X75HD/X75SD unit, use the two RCA-jack GPI inputs provided
on the Multi I/O breakout cable. To configure the function triggered by
each GPI input, navigate to System Config>Setup>GPI Input.
