ELM626 RS232 Break Detector Description The ELM626 is a plete circuit for detecting break signals on RS232 lines, in an 8 pin package. The circuit is similar to the ELM627 except that an output pulse is not generated on power-up. The threshold for break signal detection is user selectable, allowing the circuit to respond to a transmitted null character, <ctrl>@, at various baud rates. This provides a convenient means for the remote triggering of this circuit by simply shifting to a lower baud rate and sending a null byte. Two plementary high current outputs are provided by the ELM626, so that further buffering is not usually required. The output signal can be selected to be either a...
