Higher cable cross-sectional areas may be necessary in the case of long lines, as voltage drops can

be expected.

5.2.4 RS485 network topology and termination principles

• Linear double terminated bus

• Linear double terminated cascade bus with S-Node G2 in the middle.

Star formation in the wiring from S-Node G2

• Two linear double terminated cascade buses on C-Node G2.

RS485 lines from C-Node G2 can have bus formation although wiring is performed as a star

network. This can be done by using two cable pairs for the bus, "RS485 out" and "RS485 in".

C-Node G2 can be equipped with an optional connection block for this, CG2-VDE
