Re: [Elecraft] RemoteRig and KPA-500
It is not a good idea to connect pin 8 of the K3’s AUX IO connector to pin 8 of the KPA500’s AuxBus connector. The two aren’t compatible. While both need to be pulled low to power on the device, the K3’s pin stays low, while the KPA needs for its pin to go high since it is in parallel with the front panel power-on button. They both can be used for power-on, but different logic is needed for each. I believe the K3 KPA AUX cable has this pin cut for this very reason. We recumbent use of the serial power-on ‘P’ command for remote operation.

Re: [Elecraft] RemoteRig and KPA-500
I use a 15 pin D-sub "Y" connector off the back of the K3 ACC connector to connect both the RemoteRig RRC and the KPA500. Be careful to use a connector that passes through all 15 pins - many do not. (And I use another Y to feed band data from ACC to my antenna and filter switching network. It gets crowded back there in the rats' nest but it all works.) If you have Pin 8 of KPA500 AUX working for remote turn-on when the K3 comes on, it should continue to work when the RRC turns on the K3 but I can't confirm that because I don't use it here. Instead, I use KPA500 Remote client-server apps (available on the Elecraft Web site) to turn the KPA500 on and off manually. I highly recommend using KPA500 Remote with a server computer at the Remote site, rather than simply trusting that KPA500 operation will be satisfactory! I bought a surplus, commercial-grade, Win XP machine for $200. In its limited roles, it has run flawlessly. If a Remote site server is out of the question, consider a remote serial port there so you can run KPA500 Remote software at the Control site only. IMHO, it's not prudent to run high power "in the dark." GL with your integration project. It requires some patience but is well worth the effort. 73, /Rick N6XI On Tue, Jun 10, 2014 at 11:00 AM, Charles Stampf via Elecraft < elecraft@mailman.qth.net> wrote: > I'm having some fundamental issues understanding the cabling of the > KPA-500 and the RemoteRig system.

[Elecraft] RemoteRig and KPA-500
I'm having some fundamental issues understanding the cabling of the KPA-500 and the RemoteRig system. Can anyone give me some pointers to get me started? I cant figure out where to cable the amplifier as the ACC connector on the radio is occupied by the RemoteRig box. Is the additional wire to pin 8 on the KPA500 AUX connector still required when using the K3/0-Mini? Thanks for any help...
