I used to work for a local tv station but it has been a long time and I have not done much with video since. I am working with a guy to install two projectors he wants to change from BNC to ferral then back to BNC. I remeber that this conversion dosnt work one way but I dont know if it is BNC to ferral or ferral to BNC. I know this isnt on topic but any info you can give me will help.
