Notes:
Current source passive
– requires external voltage source.

5.6 Connection of RS-485 data transmission line
Fig. 5.15 Wiring diagram for RS-485.
Notes:
The device RS-485 receiver/driver allows connection of up to 32 devices.
An RS485-MODBUS configuration must have one trunk cable, along which devices
are connected, directly (daisy chaining) or by short derivation cables.
The maximum bus length depends on the baud rate, the cable (gauge, capacitance or
characteristic impedance), the number of loads on the daisy chain. For a 9600 Baud Rate
