Julius, The K2 does not have a Serial Port - it has an AUX I/O connector. Not to belabor the point, but there is a BIG difference (see prior posts).
The real answer depends on the signal lines that are connected and the cable distance between them. No one answer applies to all, it is signal specific. The AUXBUS signal line is the most critical for both drive levels and timing. It is known that the K2 can work with the full Elecraft transceiver stack and the KRC2 (the KRC2 can connect directly to the computer serial port with proper internal jumpering), but I am not familiar with the specs for the SteppIR interface, and that is not controlled by Elecraft, so you would have to pose that question to the folks at SteppIR. The TXD, RXD and Signal Ground signals are serial communications lines and are not daisy-chained, like com ports on a computer, these signals are intended for point to point connection only (the signaling protocol gets confused about which device is responding). 73, Don W3FPR > -----Original Message----- > > Another silly question: Just how many devices can I > daisy chain from the K2 Serial Port? > > Currently, I just use the KAT100 and my computers, but > soon I will need to connect the KRC2 and the > controller for a SteppIr. > > Will I need to do anything special or ??? > > _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
