I found this 4x4 Video matrix switch with RS232 that I am considering for video distribution and control thru the C4 system. Has anyone used this switch? Is there any reason that C4 wouldn't be able to control it via the RS232? http://www.monoprice.com/products/product.asp?c_id=101&cp_id=10110&cs_id=1011002&p_id=5704&seq=1&format=4#feedback
