Parameter and type
Data type
Description
STARTCOND
IN
UInt
Specifies the start condition (Default value: 1)
01H - Start Char
02H - Any Char
04H - Line Break
08H - Idle Line
10H - Sequence 1
20H - Sequence 2
40H - Sequence 3
80H - Sequence 4
IDLETIME
IN
UInt
The number of bit times required for idle line timeout. (Default value:
40). Only used with an idle line condition. 0 to 65535
STARTCHAR
IN
Byte
The start character used with the start character condition. (Default
value: B#16#2)
STRSEQ1CTL
IN
Byte
Sequence 1 ignore/compare control for each character: (Default
value: B#16#0)
These are the enabling bits for each character in start sequence
01H - Character 1
02H - Character 2
04H - Character 3
08H - Character 4
10H - Character 5
Disabling the bit associated with a character means any character
will match, in this sequence position.
STRSEQ1
IN
Char[5]
Sequence 1 start characters (5 characters). Default value: 0
STRSEQ2CTL
IN
Byte
Sequence 2 ignore/compare control for each character. Default
value: B#16#0)
STRSEQ2
IN
Char[5]
Sequence 2 start characters (5 characters). Default value: 0
STRSEQ3CTL
IN
Byte
Sequence 3 ignore/compare control for each character. Default
value: B#16#0
STRSEQ3
IN
Char[5]
Sequence 3 start characters (5 characters). Default value: 0
STRSEQ4CTL
IN
Byte
Sequence 4 ignore/compare control for each character. Default
value: B#16#0
STRSEQ4
IN
Char[5]
Sequence 4 start characters (5 characters), Default value: 0
