Pattern matching examples can be found in the back of this manual.
Event Label Enter any 32 characters. This label is for convenience only and is used in the Event Action
Table.
ASCII/ HEX
Receive Data
Enter 1- 16 characters and/or bit patterns to match against received serial data.
The received characters must exactly match the order and value of the entered patterns. If a
received character does not match the entered pattern, all previous matches are discarded and
the match process begins again with the first entered pattern. If more than 1 second elapses
between received characters, all previous matches are discarded and the match process begins
again.
Use %yz to enter a HEX character. ‘y’ and ‘z’ are values 0 - 9, A - F, or 'X' (don’t care).
Enter %Xz to match only the z part of the HEX character. Enter %yX to match only the y part of
the HEX character. Enter %XX to ignore the received value.
Use #yyyyyyyy to match an exact bit pattern. ‘y’ values are '0', '1', or 'X' (don't care). For
example, enter #0XXX1XXX to match bit7= 0 and bit3= 1. Bit0 is on the far right. Bit7 is on the
far left.
Use <yyyyyyyy to match any bit in the bit pattern. ‘y’ values are '0', '1', or 'X' (don't care). For
example, enter <0XXX1XXX to match bit7=0 or bit3= 1. Bit0 is on the far right. Bit7 is on the far
left.
Use '!' to NOT match a character pattern. For example: Event Label= TEST. Receive
pattern= !A. If any character other than 'A' is received, then TEST event is ON. If 'A' is
received, then TEST event is OFF. Use !y, !%yz, or !#yyyyyyyy to specify a NOT pattern
match.
NOTE- Spaces between patterns are ignored. Use %20 to match a space character.
