Station address

Values from 0 to 125 can be set for the station address.
Every address may only be assigned once in a network!
For the value 126, the address 126 or the address most
recently set by the Set_Slave_Address service is used.
With the value 127, the BTL can be reset to factory
settings. As the value 127 is not a valid address, no
operation on the bus is possible.

All address setting are applied by the BTL after a re-start.
Thus, changes that are made while supply voltage is
present do not have an immediate effect.
5.4.2

Bus termination

For a safe quiescent level, the bus must be terminated at
both ends in accordance with Fig. 4-10. The BTL allows
for internal bus termination by setting DIP switches S1.9
and S1.10 to ON (see Fig. 5-2).
For IP67, the bus termination resistance suggested in
Fig. 4-10 on page 11 must be used. Then, the internal
bus termination must not be activated (S1.9 and S1.10 set
to OFF)! If possible, stubs are to be avoided.
