Extron Interfaces are useful for a number of things, from acting as simple sync combiners to picture adjustment and alignment. They are frequently available on the second hand market, but some models have a less common D-sub 9 video connection, rather than the now standard D-sub 15 (VGA) connector.
Now, you can connect one of the older Extron 202Rxi interfaces to your VGA/D-Sub 15 cables using this simple adapter. D-sub 15 female to D-sub 9 female. This extends the useful life of these devices and makes finding a suitable unit easier and cheaper on the second hand market.
Tested with Extron 202Rxi but should work with other Extron interfaces too.
