7 Termination resistor
7.1 Activating termination resistor and disabling
outgoing bus cables
Figure 23 Termination resistor
The termination resistors are activated at the start and finish
of the bus system using the slide switch (pos. 2 in Figure 3,
pos. 3 in Figure 10 and pos. 4 in Figure 20). The connection
terminal blocks (2A/2B) for the outgoing bus cable are
disabled at the same time.
The termination resistor must be deactivated at all the bus
system's other node points.
