The Error Trigger
If you select this option in the condition's section of the "Trigger Settings" window, you can setup a trigger, that scans the data lines for errors.
This condition can be set for all error types, described below:
Parity Error (PE)
A data word transmitted with 5,6,7,8 bits of data gets a bit appended, showing the parity of the data bits, where even or odd mean a even or odd number of high bits (1). Mark means the parity bit always high and space the parity bit always low. If parity is used for communication, the COM port (UART chip) reports an error, if the parity bit is set in a wrong way.
Framing Error (FE)
A framing error is the result of reading a string of symbols which are grouped in blocks starting at the wrong point. In communication, the symbols are bits and the blocks are bytes, ten bits in asynchronous transmission and eight in synchronous. A framing error in an asynchronous stream usually recovers quickly, but a framing error in a synchronous stream produces gibberish to the end of the packet. Framing errors can be detected with parity bits. ComTrace can only proceed in asynchronous mode!
Line Error (LE)
Any other errors on the line.
Hint:
If one of the error conditions meets the request, the trigger gets fired!
