The “_ext”command will enable the ICO to output separate H and V syncs. Use a 15 pin to 5 BNC (R, G,
B, H sync, V sync) breakout cable(s) to connect the V6 control box to one of four channels located on
the ICO. Stereo users will use 2 channels and 2 cables (one for left eye and one for right eye). Connect
all 5 BNCs (Red, Green, Blue, H sync and V sync) to the ICO and the 15 pin to the V6 control box. Since
only one H sync and V sync BNC is available for all four channels, customers running in stereo will
need to T the H sync and V sync BNC’s to provide 2 connection points for each. Alternatively, ICO
users may download a separate VGA vfo from Virtual Research’s web site http://
www.virtualresearch.com in order to run V6 in sync on green mode. After downloading and placing this
new vfo in the correct directory, use the “setmon” command as before except use the new vfo. The
command will look something like:
%/usr/gfx/setmon 640 x 480_60_vr
Use the same 15 pin to 5 BNC (R, G, B, H sync, V sync) cable, but this time do not connect the H and V
sync.
Option 2 - External video converters (1280x1024 to VGA or 1024x768 to VGA) are available from 3rd
party vendors that will enable users to interface V6 to their Indigo Impact. Since only one graphics
channel is available, stereoscopic (3D) viewing is not possible.
Option 3 - Silicon Graphics offers Impact customers the Impact Video Option (IVO) that supports
standard NTSC and s-video formats. V6 users can then convert this video format to standard VGA
using an external video converter (NTSC to VGA). These converters are available off of the shelf at
computer and workstation related stores. Since only one graphics channel is available, stereoscopic
(3D) viewing is not possible.
OCTANE
The standard Octane currently does not support a VGA graphics format, only higher resolution
workstation formats like 1280 x 1024 and 1024 x 768. This may change in the near future, but for now V6
users have the following three options to choose from.
Option 1 - Silicon Graphics offers Octane customers the Octane Channel Option (OCO) which supports
many different graphics formats including VGA (640 x 480 60Hz). Use the “setmon” command to change
the video format outputs (vfo) of the OCO to the VGA (640x480 60Hz) format found among the list of
available vfo’s. Those users not familiar with the “setmon” command should contact Silicon Graphics
or run a “man” page on the “setmon” command for further details. The “setmon” command should look
something like:
%/usr/gfx/setmon 640x480_60_ext
