4.3.1 Using 120Ω DDF Unit
To use the 120Ω DDF unit, proceed as follows:
1) Route cables to corresponding cable bands through the cabling holes on both
sides of the 120Ω DDF unit, and then connect the cables.
2) Take off the identifier board on the 120Ω DDF unit while clamping cables.
Pay attention to the difference between "a", "b", and "s". The "s" is a grounding
cable.
3) After clamping cables, cover the identifier board. See Figure 4-9 and Figure 4-10.
