Serial Cable routing
Locked
 
|
What is the preferred serial cable routing for the full K line: K3, P3
and KPA500 ? Looks like from the KPA maunal that PC only goes to Amp.

Computer - P3 - K3
Computer - KPA500 Computer - KAT500 Neither the KPA500 nor the KAT500 are involved in the P3/K3 serial port chain.

So iPad [I can say that because I actually know you're a human being,
you hiked me a couple of miles to the In-N-Out :-)], what am I missing here? The instructions told me to go to the P3 before the K3, and to put the KAT500 in between the K3 and KPA500. This has worked for me from the very beginning, not long after the Big Bang, and for ever after ... well, at least as far as we've gotten. Full Disclosure: The computer now goes to a little boardie-thing from Pignology that runs my PigKnob, and then to the P3. The rest is all the same, and it all works, still. I thought the KAT would interrupt the KPA key line when tuning, thus it happens before the KPA on the 15-wire Elecraft Network? Oh so much to learn. 73, Fred K6DGW - Northern California Contest Club - CU in the 2014 Cal QSO Party 4-5 Oct 2014 - www.cqp.org On 12/30/2013 6:48 PM, Jack Brindle wrote: > Computer - P3 - K3 > Computer - KPA500 > Computer - KAT500 > > Neither the KPA500 nor the KAT500 are involved in the P3/K3 serial port chain. > > Jack Brindle, W6FB > > Sent from my iPad ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

You have it right, Fred.
The only serial daisy chain is from PC to P3 to K3. The amp and KAT500 have independent connections to a PC. There is a15 pin ACC cable from K3 thru KAT500 to KPA500. 83 de Dick, K6KR > On Dec 30, 2013, at 20:06, Fred Jensen <[hidden email]> wrote: > > So iPad [I can say that because I actually know you're a human being, you hiked me a couple of miles to the In-N-Out :-)], what am I missing here?

Oh Fred...
You are mixing Apples and Lenovos… We are talking two different connections. The ones I listed are for the serial port. The connection you are talking about is the 15-pin AUX cable, which indeed goes from the K3 to the KAT500, then a second from the KAT500 to the KPA500. These are two totally different communications media. Also note that RS-232 is _NOT_ involved in the AUX connection, nor is the computer (or your Pig box). The KAT500 indeed does interrupt the KEY line that is included in the AUX cable running from the K3 to the KPA500. If you have separate phono-cables that connect the K3/KAT500/KPA500, you should immediately remove them! That signaling is handled in the AUX cable! I suspect you have things cabled properly, though. Otherwise you wouldn’t be cleaning my clock in all those contests! Perhaps we should have walked further to the IN-N-Out… :-) Jack B.

Okay, sort of slow here but I'm remembering now that the serial is
computer-->P3-->K3. The 15-wire Elecraft network is K3-->KAT500-->KPA500. Got the flashlight out, looked behind the rig, and that's how it seems to be. I've got this different USB thingy by the laptop that I now know goes to the KAT500 for FW updates. For what it's worth to everyone else: I update my Elecraft firmwares when something happens in them that affects me or that I might care about. Most of the time that's not the case and believe me, I'm not current ... if it works and makes me happy, good. I retired out of the DoD hardware/software business, and I learned a great lesson. If it works good for the people who use it, don't screw with it. Didn't make our marketing department happy, but they didn't like me anyway.

The ACTIVE use of the serial connection is between P3 and K3 so that the P3 knows frequency, and between the K3 and the computer for logging and control. That's the only connection that most of us leave in place. The only need for serial to the KAT500 and KPA500 are for occasional firmware updates, which, as has been noted, don't come very often. So every 6-9 months I fire up the K3, P3, KPA, and KAT utilities, check for firmware, load them into K3 and P3 with the routine serial connection, and then use another serial cable to to update KAT and/or KPA when needed. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |
