Figure 5.5 Location of ground jumper RS-485 host interface
The jumper setting A1 shows the factory settings.
Jumper JP1 connects the internal ground of the AMC2 4W to
the ground of the RS-485 host interface.
Jumper JP2 manages the signal ground.
Settings for jumper JP1:
If the ground conductor and the shield on the host are not
connected and ...
– no party line exists, the jumper JP1 is set (= A2)
– a party line exists, the jumper JP1 is set at the first device,
only (= A2)
Settings for jumper JP2:
If the ground conductor and the shield on the host are not
connected and ...
– no party line exists, the jumper JP2 is set (= A3)
– a party line exists and signal ground is connected, the
jumper JP2 is set at the first device, only (= A3)
– a party line exists and signal ground is not connected, the
jumper JP2 is set at all devices (= A3)
