Hi all,
I recently bought an Extron RGB 202xi video interface unit, and I am attempting to use it to view the video output from an Apple IIgs on a VGA monitor.
Not sure if anyone has any experience trying this, but I've had some difficulty getting to work and was wondering if anyone had tried this before. I have a makeshift cable between the DB15 connector and the 9-pin input on the Extron with the connections I think are right, but I'm not completely sure. Also I have a 5-BNC to vga cable connecting the output to a vga monitor.
In particular what I'm seeing is that when the hsync and vsync frequencies are displayed, both show approx. 15.7k rates - which is correct for hsync, but not vsync. At the moment vertical sync going into the extron is not connected to anything, and the composite sync from the IIgs is connected to the pin for Hsync/composite sync on the extron.
Any help appreciated, thanks!
