The switches SW1 and SW3 (see Figure 5) must be in position "ON". The distance of
500m is achieved for a cable of 0.6mm diameter.
The S-bus is connected to one of the two RJ-45 jacks and has to be terminated with two
100 ohm resistors (see Figure 15). Up to 4 terminal devices can be connected to the other
end of the S-bus. The distance between the connecting points of terminal devices has to
be 25m.
