Communication Protocols
The relay does not support functions to block the transmission in a certain direction (supervision direction).

Physical Settings Digit 1: Number of bits.
Digit 2: E=even parity,
O=odd parity, N=no
parity. Digit 3: Number of
stop bits. More
information on the parity:
It is possible that the last
data bit is followed by a
parity bit which is used
for recognition of
communication errors.
The parity bit ensures
that with even parity
("EVEN") always an even
number of bits with
valence "1" or with odd
parity ("ODD") an odd
number of "1" valence
bits are transmitted. But
it is also possible to
transmit no parity bits
(here the setting is "Parity
= None"). More
information on the stop-
bits: The end of a data
byte is terminated by the
stop-bits. 8E1,
