I updated my Sony Blu-ray changer setup last night. Really pleased with the end result. Thought I'd share. Purchased a 20 port serial switch which has replaced all the switch gear I was using prior. (Well, minus the HDMI switches of course.) Far more breathing room in the back of the cabinet now after pulling out the 2 IR routers, 3 RS-232 routers, 2 RS422 to RS232 converters in addition to the 7 power supplies I was using to power all of that. It's a beautiful thing. Eye candy provided below. Enjoy!
