RE: KIO2 not working

James Kern
Well the replacement choke arrived here at the office today. I'll post an
update when I get home tonight (The soldering iron will be warming up the
second I walk through the door!.. Alright.. Well, after I say hello to my
wife!)

James:

If you want, and are really 'antsy', you can temporarily replace L2 with a
jumper and continue with your testing. Just remember to REPLACE it when the
new RFC arrives.

When you install the new RFC... bend it's leads with your fingers and
solder it in place quickly... 2-3 seconds, max.

Re: RE: KIO2 not working

James Kern
Alright,
   I got the choke installed and I now get voltage out to the pins. I
still cannot connect with my laptop, but I'm going to bring the K2
into work tommorrow. The voltages I get on J1 are as follows:

Pin 1: 0
Pin 2: -9.96 or 13.68 (It changes as I move the dial or change
anything on the K2)
Pin 3: .01
Pin 4: 5.59
Pin 5: 0
Pin 6: 5.71
Pin 7: 0.01
Pin 8: 14.24
Pin 9: 8.07

I had a 14V Supply in the K2 and had nothing connected to the J1. I
can still hear the oscillation at 16.292 mhz.

I did install the jumper between pins 7 and 8 on the PC side of the
serial connector if that makes any difference. Do I have to change
anything on the computer for that? I see this choice was optional..

Thanks,

James KB2FCV

RE: RE: KIO2 not working

James Kern
In reply to this post by James Kern
Yeah everything at least appears to be ok on the K2. The voltages seem to
line up relatively close. I'm not sure if pin 2 of J1 is supposed to change
from -9 volts to +13 volts when anything is changed on the k2 (frequency,
mode, etc).. But it appears to be doing something.

My only bit of confusion is whether having the jumper on pin 7 & 8 of the PC
side serial cable connector has anything to do with my problem?

Hi James,

If everything on the K2 side is OK and you wired up the serial cable
correctly, the problem pretty much has to be in your laptop.

First, check Device Manager to see if you have any COM ports listed (it's
not enough to just have a physical serial connector on the laptop).  While
you are there, if any are listed, make a note of the numbers - probably 1.
Then in the set up for whatever program you are using, make sure that that
number is selected.

Hope the simple approach works.

Tom, W3QS

RE: RE: KIO2 not working

James Kern
In reply to this post by James Kern
Tom,
    Here at work I tried the cable with and without the jumper - no
difference.

    I confirmed the 5th step on page 11. It is indeed set for U8-4 instead
of U6-25.

    I also tried it here at work on another machine. It's a pIII something
or other. It's a desktop PC. It has two serial ports. I verified all the
port setings in device manager matches what is called for in the manual - no
dice. We use this machine all the time to connect hyperterminal to routers
and such, so I know the port is good.

   I double checked the voltages on the KIO2 and everything looks as it
should... I'm pretty confused..

Well James,

About the jumper, I doubt if it's your problem.  I put the jumper in and
have tried several programs and have no issues with it.  I don't, however,
key the transmitter from the keyboard.  Of course you could always lift one
side and check.  

You should also confirm that the 5th step on page 11 results in seeing U8-4
instead of U6-25.  Somehow mine got switched back to U6-25 and nothing
worked until I changed it back.

At this point, I would definitely suspect your laptop.  How old is it?  The
last laptop I bought in 1999 didn't have a serial port.  Are you using a USB
emulator?

Tom

    I also tried it here at work on another machine. It's a pIII something
or other. It's a desktop PC. It has two serial ports. I verified all the
port setings in device manager matches what is called for in the manual - no
dice. We use this machine all the time to connect hyperterminal to routers
and such, so I know the port is good.

   I double checked the voltages on the KIO2 and everything looks as it
should... I'm pretty confused..

Well James,

About the jumper, I doubt if it's your problem.  I put the jumper in and
have tried several programs and have no issues with it.  I don't, however,
key the transmitter from the keyboard.  Of course you could always lift one
side and check.  

You should also confirm that the 5th step on page 11 results in seeing U8-4
instead of U6-25.  Somehow mine got switched back to U6-25 and nothing
worked until I changed it back.

At this point, I would definitely suspect your laptop.  How old is it?  The
last laptop I bought in 1999 didn't have a serial port.  Are you using a USB
emulator?

Tom

Yeah everything at least appears to be ok on the K2. The voltages seem to
line up relatively close. I'm not sure if pin 2 of J1 is supposed to change
from -9 volts to +13 volts when anything is changed on the k2 (frequency,
mode, etc).. But it appears to be doing something.

My only bit of confusion is whether having the jumper on pin 7 & 8 of the PC
side serial cable connector has anything to do with my problem?

Hi James,

If everything on the K2 side is OK and you wired up the serial cable
correctly, the problem pretty much has to be in your laptop.

First, check Device Manager to see if you have any COM ports listed (it's
not enough to just have a physical serial connector on the laptop).  While
you are there, if any are listed, make a note of the numbers - probably 1.
Then in the set up for whatever program you are using, make sure that that
number is selected.

Hope the simple approach works.

Tom, W3QS

Alright,
   I got the choke installed and I now get voltage out to the pins. I still
cannot connect with my laptop, but I'm going to bring the K2 into work
tommorrow. The voltages I get on J1 are as follows:

Pin 1: 0
Pin 2: -9.96 or 13.68 (It changes as I move the dial or change anything on
the K2) Pin 3: .01 Pin 4: 5.59 Pin 5: 0 Pin 6: 5.71 Pin 7: 0.01 Pin 8: 14.24
Pin 9: 8.07

I had a 14V Supply in the K2 and had nothing connected to the J1. I can
still hear the oscillation at 16.292 mhz.

I did install the jumper between pins 7 and 8 on the PC side of the serial
connector if that makes any difference. Do I have to change anything on the
computer for that? I see this choice was optional..

Thanks,

James KB2FCV

        Do you folks have the rs-232 port turned on via the menu?

        I use the rs-232 all the time, and this got me once.

Oh, Yes... been there done all of that.   I have tried a number of things.
Will probably just order a new one.  And then fix the old one and sell it.
