tlavite 0 Posted April 27, 2012 I have a pelco cm9500 matrix my question is about what type of keyboards will work with it... I can't find a cheap used version of the CM9505 keyboard. I'm just using this for my home system I got the multiplexer for cheap. And the only keyboard I can find is 250 bucks.. I was wondering if any pelco multiplexer keyboard would work. I work on camera systems for a living but I don't touch multiplexers much. Thanks guys! Share this post Link to post Share on other sites
