K2 KUSB PROBLEM
Locked
 
|
I thought I was clear but perhaps not--the KUSB does not work with the proper cable I built as per Elecraft instructions but the Keyspan adapter does. I am not trying to connect my K2 to my XP laptop using an RS-232 cable. Has anyone been successful connecting a K2 using a KUSB?

Eric,
You have run into a situation where the USB/serial adapter does not like to work at lower baud rates. I know it is counter-intuitive, but it seems to be true. Use your Keyspan adapter with the K2 because you have found it to work. 73, Don W3FPR Eric wrote: > I thought I was clear but perhaps not--the KUSB does not work with the proper cable I built as per Elecraft instructions but the Keyspan adapter does.

Eric,
I am using the KUSB with my K2 and N1MM Logger. I plugged the K2's serial cable into the end of the the KUSB adapter. I am running at 4800 bps, no parity, 8 data bits and no stop bits. -- 73 -- Brian -- K1LI On Thu, Jan 28, 2010 at 8:39 AM, Don Wilhelm <[hidden email]> wrote: > Eric, > > You have run into a situation where the USB/serial adapter does not like > to work at lower baud rates.

Interesting, Brian. I have always suspected that there is some other factor besides the chipset that can make the difference between success and failure with a USB adapter. Perhaps the chipset of the USB controller, or what other devices are connected to and using the same USB hub as the serial adapter. You would not think that anything so essentially simple as low speed (by current standards) serial communications could cause so many headaches. However last night I downloaded W6CQZ's new JT65-HF software and spent about two hours trying to get it to key my K3 to transmit, before discovering it would only work when connected to a real serial port. Not the virtual serial port emulator and not LP-Bridge either. I know that isn't the same as a USB adapter, except that is also a virtual serial port. It seems that anything that is not a real serial port can throw a spanner in the works if Murphy has a mind to. Partly as a result of sluggishness running the JT65 software, I ordered today a new PC for the shack. And since it doesn't come with an RS-232 port I ordered at the same time a two-port PCI RS-232 card. It cost just over £20 and I will now be able control two separate radios without needing to resort to any of these troublesome USB adapters. (I also made sure the PC I ordered came with a Windows XP "downgrade". I *know* everything I want to use works under XP, but I've seen plenty of reports of problems with Vista and 7. This won't be an option for much longer - another reason for getting a new PC now rather than later.)

Eric,
I tried that a couple of years ago and it worked for about 15 seconds. An RFC in the ground line of the 9 pin "D" jack inside the K2 opened. It's not an easy part to replace. I found there was about .3 vdc between the case of the laptop and K2. The laptop was operating from it's AC adapter and the K2 from a 13.8 vdc power supply. Others have reported success but didn't work for me. 73, Jim, W0EM |

I have had the same problem. It is most annoying to see the K2 picture (ain't she pretty!) on the HRD webpage and not get mine to work with my XP machine over the serial-to-USB converter.
After a lot of tests, I have concluded that there is something amiss in the converter and the HRD software. Why? The same converter/k2/cpu combo works fine with Logger32. I've tried 2 different chipset converters with the same results. The most recent is one from IOGear that has a polling light on it which provided this interesting tidbit of info: when using HRD, the polling light does not show a consistent polling rate. There are times when the light flickers more than once in between the 500mS polls. Meanwhile, the frequency display (and subsequent data loaded into the log) varies: sometimes it is 7.042.50 like the rig says, sometimes it is 70 while other times it is just 7042. One other test: on another computer using a REAL RS-232 interface, HRD and my K2 act like a happily married couple. I know this test changes two variables but it is an interesting data point. So, I've stopped trying to figure it out and will be content to use Logger32 instead of HRD until such a time that the shack computer can have a REAL RS-232. Since the computer is a laptop and doesn't have an empty slot available, it's either throw out a completely working computer or wait for it crash. Now, the disc drive has been acting funny, so maybe there is a new shack computer in the future... Remember when ham radio was only about radios??!! 73, Clark KE4RQ |

Did you try 1 stop bit in the COM port settings? I think the K2 manual says 2 stop bits but I have had problems using 2 stop bits that went away when I changed to 1.
The double flash probably means the data is being fragnmented. I wouldn't have thought HRD would assume that a response from the radio would never be broken in the middle, because Simon is a professional programmer and knows what he is doing. I did originally make that assumption in KComm, which is how I know that it happens, but I'm only an amateur.

There are several threads on the N1MM logger reflector that relate to
a weakness with Prolific drivers/chip for USB/serial converters, perhaps exacerbated by operating system level. I don't have the specifics, but it has something to do with not responding to delayed replies to queries. Just on the surface of it that could make for some baffling problems. Perhaps a bit of time in their archives would be useful. 73, Guy. On Tue, Feb 9, 2010 at 11:58 AM, Clark Macaulay KE4RQ <[hidden email]> wrote: > > I have had the same problem.

Thanks, Guy. What’s so interesting is that one of the converters has the
Prolific chipset and works fine with Logger32 but won’t work with HRD. I’ve
not tried it with N1MM but will definitely try it tonight. 73, Clark KE4RQ From: Guy, K2AV [via

N1MM works fine. Logger32 works fine. HRD doesn’t work. I know HRD is solid piece of code and is in use by many people
with Elecraft rigs. I’m inclined to think there is a setting somewhere in HRD
that is amiss but I can’t figure out where that might be. There is very limited
control of the COMM port offered to the user. Or maybe there’s something amiss between HRD and Windows XP. I’m gonna keep at it until I win! 73, Clark KE4RQ From: Guy, K2AV [via

Hi, Julian. Yes, I changed the Stop Bit on the USB to Serial Port to 1 and
set the speed to 4800 baud. I can find nowhere in HRD where the Stop Bits
can be set or changed; am I overlooking something? At the K2 end there is no
flexibility in settings (unless there is a hidden menu I’m not aware
of). Results: N1MM works; Logger32 works; HRD doesn’t
work. I’m running Windows XP with all the latest patches.
There is something not right in HRD and I’m thinking it is between my OS
and HRD because HRD is solid and in use by 1000’s of hams. I just
can’t imagine what is amiss but will continue to try and remedy it so I
can HRD. 73 de Clark KE4RQ From: Julian, G4ILO [via

Clark, et al:
It is frustrating all right. However, with my K2, XP laptop, and HRD, it DOES work with a Keyspan USB converter. The consensus I heard from off-list replies on this problem was that some USB converters do not run well at the 4800 bps speed of the K2. Some folk said their K2 worked with a KUSB and HRD, some said it did not. My K2 will also not work on HRD either using a serial PCMCIA card in the laptop that has two ports-- COM13 and COM14. I normally use this card with the K3 and W2, and it works great there. I like that the COMxx numbers never change with it--avoids additional confusion when I can't get WSJT to work at 3am... For the record, I am using a proper Elecraft-designed, DBM-built cable not a stock RS-232 cable which should never be used alone to connect a K2 to anything except--of course--an oscillator overthruster or flux capacitor. 73, Eric WD6DBM I still LOVE my K3, K2, K1, KX1, XV-432 XV-144, T1, W2, W1, XG2...etc!
