Crestron QM-FTMC 

than or equal to 15 ns over its entire length. For example, if using a cable with a 
rating of 15 ns/100 meters (100 meters = 328 feet), connecting the QM-FTMC 
transmitter with 150 feet of cable to a QM-MD7x2 switcher, and then using 
another 150 feet to connect the QM-RMCRX-BA receiver, the accumulated 
skew over the entire 300 feet should not exceed 15 ns.
