KRC2 + K2 + XV + PC = cabling confusion
Locked
 
|
So .. not a moment too soon. I've completed the new XV144 to use as
the intermediate IF in my rover microwave setup. Now I've already configured the system such that the K2 connects to a KRC2 with a custom map, and the KRC2 switches around all sorts of stuff for me. Last time out I ended up using an IC706 as the IF rig when the equipment I was going to use didn't work. So now this time I'd like all these things to play together .. the K2 driving an XV and the KRC2 and Roverlog. Looking at the KRC2 manual, it sort of indicates an either/or scenario, and jumpers determine whether the PC side of the cable gets AUXBUS ans 8R and other control signals. Since I want a PC on there, can I just parallel the K2 end? I was using a straignt serial molded 9-pin cable between the K2 and the KRC2, now I'll have to build one (or maybe just hack into it and splice). de w1rt/john _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

John;
As I recall your configuration, your KRC2 uses the band info from the Auxbus to select the various transverters. I don't believe that it needs the RS-232 communications for your use. This means that you can fabricate a cable that connects the K2's serial port to the computer. The KRC2 and the XVT both need most of the remaining signals, so you can connect them from the K2 to the KRC2 and the XVT in any convenient fashion. The easiest would be to cable from the K2 to the KRC2, then from the second KRC2 connector to the XVT. You might want to look at the cable fabricated for the KAT100, it provides the connections you need, so something very similar might be the way for you to go. Good luck with it, let me know if you need help. On Sep 2, 2006, at 3:07 PM, John D'Ausilio wrote: > So .. not a moment too soon.

Heya Jack ..I took the "easiest" path and just connected on the PC
side of the KRC2 .. 2,3,5 to the PC, 6,8,9 to the XV and added necessary jumpers (all but ALC). Only thing I'm worried about is the total cable length on AUXBUS, from K2->KRC2->XV is about 4 feet ... I'll know later today when it moves off the bench and into the jitney :) thanks jd On 9/2/06, Jack Brindle <[hidden email]> wrote: > John; > > As I recall your configuration, your KRC2 uses the band info from the > Auxbus to select the various transverters.
