coaxial cable used.
Type
3C-2V
5C-2V
2) When connecting a coaxial cable, the following restrictions on the bending
radius must be observed.
Cable type
bending radius
3C-2V
5C-2V
3) The Coaxial cable is wired in the following manner.
There is no problem even if not wiring in order of the station number.
There is no problem even if station how many become control station.
