3. To determine which is pin 1 on the cable, hold the cable so that the end of the eight pin modular jack
is facing away from you, with the clip down and copper side up. Pin 1 is on the far left.
4. For QM wiring use CresCAT-QM, CresCAT-IM or quality CAT5e/CAT6 cable with a maximum
delay skew of 15 ns per 100 m. The maximum aggregate cable length and delay skew between any
QM transmitter (origination point) and QM receiver (endpoint) is 450 feet (137 meters) and 22 ns. A
maximum of two QM midpoint devices may be inserted into a given QM signal path. Exceptions
apply; refer to each respective product manual for details.
