Decoded |
Displays the decoded DTMF digits and other characters as they are received by the device. As each digit arrives, it is moved to the rightmost position position. You can use this field to confirm that the encoding and decoding process is working successfully. |
Pattern n |
The string pattern to be matched in the incoming data. It may only contain the digits 0-9,A,B,C,D,*and #. We suggest that the # key be reserved for an enter function. This is an effective way to signal the end of the string and also helps prevent detection of partial strings. We also recommend that command strings are the same length. This is not a requirement, but the designer must be aware that if string1 is set to 4321# and string2 is set to 54321#, when the input sequence 654321# arrives, both Match LEDs will be lit. Tip: The digits A, B, C and D can be used to secure command sequences, as they are not present on standard phones – only military phones and certain custom dialing devices. |
