Overview
ELM627 RS232 Break Detector Description The ELM627 is a complete circuit for detecting break signals on RS232 lines, in an 8 pin package.
This is useful for remotely resetting circuits through a serial link.
For convenience, this circuit also generates an output pulse on power-up.
The timing threshold for break signal detection is user selectable, allowing the circuit to respond to transmitted null characters, @, 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 complementary high current outputs are provided by the ELM627, so that further buffering is not usually requi...
