Description
Requirement: "EndDetection = 1"
Entry of the first end delimiter of a
maximum of two end delimiters for
the end criteria "On receipt of the
end delimiter(s)". The selected end
delimiter or the selected end delim-
iter combination limits the length of
the frame.
Parameter value depending on the
"DataBits" parameter.
Requirement: "EndDetection = 1"
Entry of the second end delimiter of
a maximum of two end delimiters
for the end criteria "On receipt of
the end delimiter(s)". The selected
end delimiter combination limits the
length of the frame.
Parameter value depending on the
"DataBits" parameter.
Requirement: "EndDetection = 2"
Entry of the frame length in bytes
for the end criterion "On receipt of
fixed number of characters".
Requirement: "EndDetection = 3"
Entry of the time [ms] that can
elapse until a frame end is recog-
nized. Select the character delay
time dependent on the sending
behavior of your communication
partner. Depending on the data
transmission speed the character
delay time is limited to a minimum
value.
Note that the ASCII driver also
pauses between two frames during
transmission.
