Timeout / Detect end of text

A timeout after the last character is one way of determine when a text is fully received.

• Possible timeouts:

• 50ms, 100ms, 200ms, 500ms, 1s and 2s

“Detect end of text” uses a sequence of one or two characters to determine when a text is ful-

ly received. To enable the use of non-printable characters the IRIS-unit uses the ASCII-codes

for the characters, the decimal value. It is possible to use one of the predeﬁ ned sequences or

enter a user-deﬁ ned sequence.

• Predeﬁ ned sequences:

• 13,10 (CRLF), 13 (CR), 10 (LF) and 3 (ETX)

It is possible to use both “Timeout” and “Detect en of text” at the same time.
