[Elecraft] ACOM 2000A and Elecraft K3
I think I have figured out the connection issues when using a K3 with an ACOM 2000A. I wrote up the following mini-tutorial to try to clarify what is, to me, a confusing situation. Please read it and let me know if I have made any errors and whether you find it helpful. If you find it helpful, feel free to copy and distribute any way you wish. Thank you, 73, Bill W6WRT +++ When operating an ACOM 2000A with an Elecraft K3, there are two possible modes of frequency control. Each mode requires a different cable. When a PC is NOT connected: Use a cable like that shown in figure 7.6 of the ACOM 2000A manual. You should set the K3 AUTOINF menu option to 1. In this mode the 2000A will poll the K3 for band data and will change bands accordingly. The K3 will also send band data when you manually change bands on the K3. When a PC IS connected: Use the cable shown in figure 7.2 in the 2000A manual. You should set the K3 AUTOINF menu option to nor. Note that this cable does NOT have the TXD wire going to the ACOM 2000A, but it does have the TXD wire running between the legs of the Y connector. This cable can be either a single cable terminating in two DB-9 connectors or it can be a single cable with a Y adaptor connected at the DB-9 end. In either case, it must be the electrical equivalent of figure 7.2. In this mode, the ACOM 2000A gets band data information ONLY from the logging program, not from the K3. If you close the logging program, the ACOM 2000A will NOT follow band changes from the K3. You can still do band changes by sending a dit as explained in the ACOM 2000A manual. __ 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
Re: [Elecraft] ACOM 2000A and Elecraft K3
Bill, According to your description, AUTOINF=NOR is the right setting in both cases. Either the ACOM 2000A, or PC will poll the K3, hence no need AUTOINF to be changed. 73, Val LZ1VB I think I have figured out the connection issues when using a K3 with an ACOM 2000A.

I had tried it both ways and I thought the correct setting was =1 but apparently I was mistaken. I will make the change. 73, Bill W6WRT __ 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
Re: [Elecraft] ACOM 2000A and Elecraft K3
Bill, Setting AUTOINF to 1 the K3 will report any changes over the RS-232 bus - this is not polling - it is information send by the K3 without any polling requests. I don't know the ACOM 2000A capabilities, but if it does poll the K3 for information, the proper setting for the K3 is AUTOINF = nor. Yes, when a logging program is involved, the logger will poll the K3 for information, and the ACOM may 'listen in' and respond to band changes, etc. In that case, the K3 should be set to AUTOINF = NOR. 73, Don W3FPR On 10/27/2014 3:13 PM, Bill Turner wrote: I think I have figured out the connection issues when using a K3 with an ACOM 2000A.
