Hugh, If you are not using the RemoteRig's COM1 port to control another device, you can route CAT over that port to sync devices such as the SPE Expert (which I do).
Just change the radio RRC to mode-6. Then connect a serial cable between (for example) the SPE's CAT input port (one of the DB25's) and COM1 of the RRC. Note that the pinout of COM1 is different than COM2 (mirrored). In some cases, using a Y-cable as you said allows you to sync as well, but no guarantee. If you are not yet using CAT on the control RRC, just use the same trick with mode-6 on that RRC to be able to control the K3 that way. You can then use LP-Bridge or similar to sync with other devices on the control PC. 73, Mitch DJ0QN On 07.08.2012 22:43, Hugh Bradley wrote: > I spend a lot of my time connecting and disconnecting accessories from the > back of my K3 and I find this tedious. > > In my shack I have a, Expert 1K linear amp and a Microkeyer II which both > like to use the ACC Port on the K3 I use a Remote-rig unit to control the > K3 when I am away and this too needs the ACC. > > Instead of connecting one of these items at a time, is it OK to use a VGA > cable splitter and have both or three connected simultaneously? > Is this port a strictly one-at-a-time guy? > > In addition to the issue with the ACC port, the accessories above (+ add to > this a Signalink USB) I find that I am regularly having to change the plugs > into my: Line-in , line-out, Paddle, Key, PTT and Speakers sockets and > RS232 port. > > Which of these 'ports' can be shared or split and which will will only > safely take one I/O? > > I am tempted to build an external 'Patch Box' to give me handier and easier > access to the K3 back-panel . > > Has anyone built one of these or is it even necessary if the ports can be > split and permanently shared? > > I believe that Y cables are available for the RS232 on the K3. > Into how many RS232's can these be split? > 2...3....4? > I have an Expert-1K, a CAT, and a Steppir controller and a Remote-rig - all > of which would like a place on the nipple! > > Thanks and GB > > 73 de EI9KF > Hugh > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:[email protected] > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > -- Mitch Wolfson DJØQN / K7DX Georg-Kerschensteiner-Str. 42, 81829 Muenchen, Germany Skype: mitchwo - Home:+49 89 32152700 - Mobile:+49 172 8374436 Echolink: 3001 - IRLP: 5378 ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
