4. For QuickMedia wiring, use CAT-QM-P, CresCAT-QM-NP, CresCAT-IM-P, or quality
CAT5e/CAT6 cable with a delay skew of
≤
15ns per 100m; the maximum aggregate cable length and
delay skew between any QM transmitter (origination point) and QM receiver (endpoint) is 450 ft
(137m) and 22 ns; a maximum of two QM midpoint devices may be inserted in a given QM signal
path. (exceptions apply, refer to each respective product manual for full detail).
