Star wiring
Another possible way of operating multiple devices on the RS485 bus is called star wiring. In this wiring
variant, a HUB 6 Port RS485 S is used to seperate the bus into a serveral bus strings. To connect the
HUB 6 Port RS485 S to the IBC SolControl, please use a Connect Universal RS cable.
Various devices can only be queried together if they communicate with the same protocol and have
identical serial communication parameters (baud rate, number of data bits, parity, stop bits).
Each bus string can have a maximum length of 1200 m. All the devices on the same bus string are wired
together in a daisy chain. The first and last device of each bus string must be terminated with a resistor.
The HUB has integrated terminating resistors at each interface, which are permanently activated.
In this wiring variant, the total number of bus devices may not exceed the maximum permissible number of
bus devices.
