The baud rate can be changed during
operation by means of the function
code 0x41 and is permanently saved in
the slave.
The relative parity bit can also be
dened. None, Even and Odd are sup-
ported.
Default values (upon delivery) are
19200 bauds and Even Parity.

Bus termination
A termination resistor is required on
the rst and the last device of the bus
structure.
Alternatively to internal termination
(see above), an external bus termina-
tion resistor can be connected instead
of another bus cable.
The bus cable shielding is to be con-
nected to PE to avoid electromagnetic
radiation.
