Interfacing Circuits

Top  Previous  Next

The following circuits may be used separately or in conjunction with the remote alert circuit




 Serial interface for Morse keyer






Parallel interface for Morse keyer




If you are using a serial port for keying then you may use any port whether it is capable of interrupt driven operation or not. If you have COM 3 or 4, then I suggest you use one of them, leaving COM 1 and 2 free for other more demanding interfaces such as the TNC and transceiver computer links.
