Connecting the devices to the LAN coupler
All the devices are connected in parallel with a shielded two-wire
cable. Point-to-point installations, junctions or ring installations
are not possible.
Grounding potential
Both the LAN cable with the RJ45 connector and the shielded
cable of the RS 485 bus system must be grounded. This also
applies to the devices connected to the LAN coupler.
