ATI 7-pin mini DIN
The S-Video and RCA
connectors
7-pin mini DIN connector on one end and:
One female RCA Composite Video Jack and,
One female S-Video 4-pin mini DIN jack on the other end
This adapter is used on some ATI cards to output either the S-Video signal (on the 4-pin mini DIN) and the Composite Video on the RCA Jack.
In addition, this adapter was used on many Compaq computers that bundled the ATI board. Some models of the Compaq Presario 53XX computers require this adapter.
