[Elecraft] K3 serial port

[Pete Smith N4ZR]

Thanks to everyone who offered educated thoughts on my problem.  I just 
discovered that the problem apparently lay in my USB hub, perhaps as 
simple as a loose connector.  I plugged the USB cable into a computer 
port directly and voila!  So I now have frequency control communications 
again.  All I'm lacking now is to clean up the Windows registry and, 
hopefully, be offered a good port again for my CW/Other function, so 
that I'll be able to send CW from the keyboard.

[Elecraft] K3 serial port fix?

[David F. Reed]

How difficult is it to replace (realize I am challenged in the delicate 
touch department) whatever board in the K3 does the serial 
port/interface to the radio?


Is it likely a go back to the factory thing or an easy desktop job for a 
klutz (me)?


The reason I ask this is my K3 suddenly seems to respond to input from 
DXLab Commander, but not send out changes like VFO, band switching, 
etc.  I suspect its the K3. and will confirm tomorrow by using a 
different PC to talk to it...


Thoughts?

Thanks & 73 de Dave, W5SV

Re: [Elecraft] K3 Serial Port Fixed!

[Martin]

I seem to have the same issue with my K3 I/O board.
I have a temperature controlled heatgun and will try to solder out the 
IC if it turns out to be true AND if i knew what temperature to set it 
to. Anyone?

Re: [Elecraft] K3 Serial Port Fixed!

[Jim Wiley]

Before you try this on your K3, get a couple of old computer boards 
(junk motherboards, expansion cards, etc) and practice on them. Only 
when you can remove and / or install components from the junk boards 
successfully should you try the same with the K3.  Just my 2 cents worth

[Elecraft] K3 Serial Port Fixed!

[Paul A. Thompson]

Thanks, Elecraft Reflector friends!  Thanks to MontyS, Matt Zilmer, and
Howard Stephenson, I have the K3 serial port working once again!  Howard had
me check the voltage on pin 8 of U1 on the KIO3 main board, and it was less
than -5V (about 120 mV) with the serial cable plugged in.  This was the
first clue.  The second was that the lettering on the package of the IC
itself was discolored/faded in the center section of the IC, a sign that the
chip had overheated at some point.  In any case, replacing the U1 serial I/O
chip did the trick.  I had a friend with lots of experience at soldering and
unsoldering surface mount ICs remove the bad chip, clean up the solder pads
and tack down and then we soldered the pins of the new IC (.05 spacing, I
believe) using a micro soldering pencil.  If anyone is interested, I'll find
out and pass on the specifics of the heat gun we used for removal and the
soldering station that did such a fine job with no damage to board or
surrounding parts.  Thanks again, guys, and I should be back on the digital
modes today with HRD!

 

Oh, and once I had the info on the part no. and got it ordered, it came 1st
class mail from Elecraft within four working days. not bad.

 

73, and Merry Christmas to All, and may your dreams include visions of sugar
plums (2nd receiver board, 2 mtr xvtr, etc) dancing through your head.

Re: [Elecraft] K3 Serial port problems?

[Cady, Fred]

Hi Ross,
Get yourself an RS232 tester. There's one at amazon.com for $6.  With it
you can quickly tell if the serial port on either end is working.
BTW, you do have the RS232 baud rate the same on the computer and
radio??
Cheers,
Fred

What are you serial port settings on both your computer (you didn't
say your platform) and your K3 (CONFIG-RS232)?

One thing that often goes wrong to kill RS232 is different speed 
settings on radio and computer.  They must match.  38,400 is a great 
choice.  Set the computer in your logging software, set the radio in the 
K3 long push menu.

If that's good, go into the Windoze Control Panel, open the System 
section, select Hardware from the top section, and scroll down to the 
ports. Check the RS232 ports to make sure they're working (and not 
turned off).

[Elecraft] [Elecraft K3] Serial port test

[David Robertson]

When Windows is started, The operating system checks the Device Manager to see 
what is set up on your system.  When it sees the serial ports (both real and 
USB to Serial) Windows exercises all the output lines of all the serial ports 
on the system to test them. This can result in a very quick keying of the K3 
(mine does it 3 times). If the K3 is in SSB or CW mode there will be no output 
but if you have a linear on during this time it will see a PTT input during the 
port test.

I always have the K3 (and linear) off when I reboot or turn on the computer. I 
also have the linear in stand by or off before I turn on the K3.

There are many rigs which will have a short transmit burst when powering up, K3 
included. Unless you are running an analog rig your rig stands a good chance of 
doing the same thing

Re: [Elecraft] [Elecraft K3] Serial port test

Most good rig control software can do PTT by sending TX; and RX; commands so
you can turn the RTS and DTR options off in the K3 and avoid this problem.

Re: [Elecraft] K3 Serial Port Connections

I have the rotor on a separate port. SteppIR sells a cable that goes 
from the computer to the radio to the control box 
(http://www.steppir.com/files/USWebPriceList.pdf  #02114).

I can't help with the amp hookup. How does the amp manual say to do it?

FWIW, I use USB to serial cables, and have no problems with them. Not a 
clue as to the brand, they weren't labeled.

Re: [Elecraft] K3 Serial Port Connections

John,

That is actually up to the user to determine.  It does require an 
interim intelligent device.
Check out LP-Bridge or several other serial port sharing applications 
that run on your PC.
The K3 is a terminal device, it does not provide control for all RS-232 
based communications.  Refer to the K3 Programmer's Reference to see the 
data that is sent to/from the K3.

Yes. The advanced settings have nothing to do with the RS-232 control signals, 
unfortunately. And there is no replacement serial driver. Googling various

Thanks for that info, Matt. Did not know that.

No controls in the BIOS anyway. I'll just have to live with it I guess. 
Fortunately, I can use VOX for TX control and don't really need to use the 
RS-232 control signals.

 I have never used VOX. Why would you need to? If you have a fully

Julian et al.,

I have always used VOX for WSJT keying, so I tried setting it up for RTS 
control 
as you suggest above. But when I try to configure the K3 for ether PTT=RTS or 
PTT=DTR with NO RS232-controlling application (like WSJT) running, the rig keys 
up (and switches into TEST mode automatically as per the manual). If I then 
disconnect the serial cable at the laptop serial connector, the keyed condition

My conclusion is that the laptop's serial port is asserting RTS and DTR 
full-time for some reason. It's a 2-year-old Dell Latitude D820, Core2 
processor, 2 GHz, 2 GB RAM, running XP Home. It has one true RS232 port (COM1), 
the one I'm using. Flow control is set to NONE, so it should not be asserting 
these lines by default. Has anyone ever encountered this?

Re: [Elecraft] [K3] Serial port RTS problem [was: Different mode]

[David Christ]

It may be a too obvious comment, but the easiest way to tell what is 
going on is with a serial breakout box.  If you get one with LEDs you 
can visually watch the status of the control and data lines in real 
time.

I have always used VOX for WSJT keying, so I tried setting it up for

as you suggest above. But when I try to configure the K3 for ether PTT=RTS or
PTT=DTR with NO RS232-controlling application (like WSJT) running, 
the rig keys
up (and switches into TEST mode automatically as per the manual). If I then
disconnect the serial cable at the laptop serial connector, the

disappears.

Re: [Elecraft] K3 Serial Port

[Larry Phipps]

Eterlogic can work as long as the two programs don't poll much, reducing the 
chance of collisions. It takes all incoming data and mixes it together, which 
can cause lost or corrupted commands. It also sends all K3 responses to all 
connected programs, which can be a problem with some programs, which may not 
support all the incoming commands. Some programs also require a proper response 
to each command in sequence, and will be confused by a response that was not 
just polled for.

It is a very useful program for many things, though, and should make a good 
addition to LP-Bridge for some of the more exotic setups requiring bridges 
between programs and hardware, a second PC, etc. As long as the connection is 
one-to-one (or one-to-many under some circumstances) it should be fine, but I 
haven't tested it.

Larry N8LP

Another solution is provided by Eterlogic's Virtual Serial Port Emulator, 
a free download from Eterlogic's web site.  You can create a serial port
splitter, for using diifferent software programs that talk with the K3.

I use it to run DXBase 2007 and DXLab's Commander program
simultaneously.

[Elecraft] K3 Serial Port

[Stan Rowe]

I'm missing or forgetting something rather basic I think.  I have my computer 
connected to my K3 with a serial cable.  I normally use the connection for 
DX4WIN but sometimes want to use Digipan for PSK.  Of course if I try to use 
Digipan while DX4WIN is running, I get a message about the port (serial cable) 
already being in use (by DX4WIN).  How can I connect the computer and K3 so 
that I can have both DX4WIN and DIgipan (and perhaps other programs in the 
future) active at the same time.  I feel like I ought to know the answer, but 
somehow it is escaping me.

Thanks for your help.

Re: [Elecraft] K3 Serial Port

[Lee Buller]

You will need to get another COM port.  If you have a desktop computer, that is 
easy because  you can buy a card to go into an expansion slot.  Then you would 
have COM1 - COM2 - COM3 etc.  Now you can also go with a USB to Serial adapter 
(Elecraft sells one) and then you can add addition COM ports with that do-dad.  
But, they do work rather nicely in a lot of applications.  I blew up mine 
because of of some RF in the shack.  Stopped working.  I went with the COM port 
card.  You can get a card with two or four COM ports for around 10 to 30 
dollars.

Re: [Elecraft] K3 Serial Port

[Iain MacDonnell - N6ML]

Umm, adding a second serial port won't help if both apps need to talk to
the K3!

Try running LP-Bridge, and connecting the two apps to (different)
virtual serial ports that it uses.

I don't use DX4WIN nor Digipan, but other combinations of apps seem to
work quite well.

Re: [Elecraft] K3 Serial Port

[Ron D'Eau Claire]

*If* the need is for a second serial port (that's not clear from the
thread), CommFront (www.commfront.com) makes a nice single USB to two RS232
port dongle that works FB for me. It's supposed to work with all the
currently popular OS's out there today including Linux, Windows and Macs. 

I've used it with 32 bit Xp and 64 bit Vista.

Re: [Elecraft] K3 Serial Port

[Jim Miller KG0KP]

A friend put me onto EDGEPORT USB to serial devices.  Run 300-400 new.  Ebay 
has them (take-outs I think) and I bought a 4 port one for 25 and an 8 port 
one for 35.  Love them.  Hardware has comm 1 and 2 and the Edgeport software 
configures to comm 5-8 or 5-12.

Using the 4 port one with Windows XP Pro to K3, PSKMETER, and TM-D710 right 
now.  Works FB.  The 8 port is for my second shack PC and will connect the 
remaining radios, TNC, rigblaster to my 746, and my other 2 meter rig.

I can echo Jim's endorsement of the Edgeport device. I have the Edgeport/8 on

Re: [Elecraft] K3 Serial Port

[Erik N Basilier]

I use an EdgePort with 2 serial ports and can testify to their quality.
Bought this years ago when the cheap versions didn't work very well (at 
least that was my experience).
In contrast, the EdgePort worked right from the start, and the EdgePort 
people provided great support when I wanted to change the configuration.
This is the expensive Rolls Royce of serial ports, and these days the cheap 
ones seem to work fine.
But if the EdgePorts can be had cheaply on ebay I wouldn't hesitate to 
choose the same brand today.
