SGI Monitor Ports

Flat Panel Adapter & Digital Video Port




SGI OpenLDI Port

OpenLDI was an interface used with laptops or notebook computers.
The standard was released in 1999, but rarely used except on a few SGI computers.
The pin out table relates to a 36-pin MDR connector.
This video interface is no longer in common usage and would be found on legacy hardware.

This pin out table represents an interface that is no longer in service.
Also this video monitor interface is obsolete and should not be used in new design.
It may be possible that this system is still in operation, but the odds are against it.
However Silicon Graphics or SGI is still in business.

Back to the main PC Video Monitor Bus page, or to the main PC Interface Bus page.
Use the Buses icon at the bottom of the page to reach the top level index for all bus types.
Use the Equipment icon at the bottom of the page to reach manufacturers of PC Monitors.

SGI Digital Video Port

This pinout is used with the Silicon Graphics Inc [SGI] Digital Video Port for the O2Cam.
The O2 was a workstation produced in the mid 1990s
This represents the I/O port between the workstation and the digital camera.
This interface [pinout] is obsolete, also called signal assignments.

Use the Buses icon at the bottom of the page to reach the top level index for all bus types.
Use the Equipment icon at the bottom of the page to reach manufacturers of PC Monitors.
Note; this interface also uses the I2C Bus to send control information.

Back to the main PC Video Monitor Bus page,
or to the main PC Interface Bus page.

Silicon Graphics makes Servers and Work-stations, among other things.
Editor Note; This pin out is a snap-shot, those reserved pins may have been utilized in another revision.

This pin out represents an obsolete interface, and may no longer be used.
In fact you would be hard-pressed to find a camera with a 68 pin cable assembly attached to it self.
Finding a 68 pin PC interface should also prove difficult, but not impossible.
