*1: For twisted pair cable, use shielded low-impedance cable with a thickness of at
least AWG#22 (0.33 mm
2
).
*2: Keep the overall length of coaxial cable under 1200 m {3937 feet} (in the case
of RG-6/U (5C-2V)).
*3: Be sure to connect the grounding lead to the GND terminal.
*4: Since a female cable is not attached, cut off the connector and connect to the
twisted pair cable of the same type.
*5: The type of twisted pair cable is AWG#28.
*6: The type of twisted pair cable is AWG#26.
