"My first thought is that, since the antenna controller just sniffs for data, I could add a DB-9 Y-cable to provide the extra port at the controller serial port location. However, packets could still collide ...does the protocol handle this? Is there some sort of multiplexer available?"
If only one device is doing the interrogating then there cannot be any conflict and there is nothing to multiplex. Typically the listening device will only need a 2 wire interface (TXD and GND). My KPA500 just listens to my TS-590 responses to Omni-Rig. Multiple receivers can listen to an RS-232 transmitter, just be careful not to try to make a TX talk to a TX and that may happen if you make a poor choice of Y cable. 73, Andy k3wyc ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
