Re: [time-nuts] Lucent RFTFm-II-XO- Lady Heather question-having issues

[Ken Winterling]

Chris,

Your GPSDO has a Bps, stop bit, and parity setting.  That has to match the
COM6 settings.  If you know the default, or current, port setting for the
GPSDO then you need to go into Windows Device Manager and set COM6 to use
the same characteristics.

To check/set the COM6 port characteristics in Device Manager do the
following:
1. Right click on the Start or Windows button, usually in the lower left
corner of the screen.
2. In the list of devices find "ports (COM & LPT)"  and double click it.
3. Double click the COM6 entry.
4. Click on the "Port Settings" tab and you will see the COM6 parameters.
Set them to match the GPSDO and click "OK".

Try LH again and advise what you see.

Re: [time-nuts] Lucent RFTFm-II-XO- Lady Heather question-having issues

[Chris Waldrup]

Fantastic thanks for the help guys!!
I now have LH seeing com 6. 
Is it possible to check/change the baud rate of LH? When I connect up the 
Lucent box it says "No COM6 serial port data seen".
I exited LH and opened Hyper terminal and with 9600 baud and COM6 I am getting 
a data stream that stops when I unplug the 422 cable from the Lucent box so it 
looks like the GPSDO is talking to the laptop. 

I'm hoping it's just LH is set to another speed. 

I pressed spacebar for help but didn't see it as an option. 

I also appreciate the information about the first LH icon that comes up with 
TBolt, Seattle. I was curious how on first opening up the program it was seeing 
satellites and plotting signal strength before  I had even connected the GPSDO. 
Now I know.

Re: [time-nuts] Lucent RFTFm-II-XO- Lady Heather question-having issues

[Ken Winterling]

Chris,

Right click on the Lady Heather icon (not the KE5FX one).  At the bottom of
the list, click on "Properties".  You will see a number of tabs.  Click on
the "Shortcut" tab.  In the "Target" text box you should see
"C:\Heather\heather.exe" if you installed LH on the C: drive.  If that is
the case just add " /6" for COM6, that is a space folowed by /6, to the end
of the line.  It should oook ike this: C:\Heather\heather.exe /6.  Click
'OK".  Now when you click on the LH icon it will use COM6.

I have assumed that your GPSDO and the COM port have the same baud, stop
bits(s), and parity.

Hi

In Windows, the icon on the desktop has a set of properties. One of those is 
the command that clicking the

Re: [time-nuts] Lucent RFTFm-II-XO- Lady Heather question-having issues

[Chris Waldrup]

Hi,

I downloaded the latest version 4.00 beta of lady Heather on my win XP laptop. 
Installation creates two icons on my desktop. One says KE5FX TBolt (Seattle 
USA) and has the lady Heather icon and the other has the icon and simply says 
Lady Heather. 
When I try and open the Lady Heather icon (not TBolt one) an error box pops up 
and says Can't open com port:\\.\COM1 and will not open the software. Opening 
the TBolt version icon instead will open the program. 

What did I do wrong?
Also the RS422 adapter shows up as com6 and I see in the instructions to change 
a command line to /6 for com6 but I am not sure where to find the command line.

Thank you. 

Chris

I also wanted to mention that I can't get the Lucent to communicate at all with 
the TBoltMon program so that's why I decided to try LadyHeather. 
I do hope I connected the cable pins right, I connected Lucent RS 422 TX pins 
to the USB to 422 adapters RX pins and the Lucent 422 RX pins to the adapters 
TX pins.

Re: [time-nuts] Lucent RFTFm-II-XO

[Charles Steinmetz]

One additional point:  Many ordinary PC sound cards do not have proper 
input filtering, so anything as fast as a PPS pulse will cause severe 
aliasing, even after it has been voltage-clamped to a level that will 
not overload the ADC.  (Thus my mention of LP filtering under pulse 
conditioning.)


The sound cards that do have adequate input filtering generally use 
rapid-cutoff filter alignments, which can ring like crazy -- very much 
what you do not want when you are trying to use a pulse for timing.


So:  Best to slow the pulse rise- and fall-times down so you are not 
banging on the input filter (if present), or causing aliasing.


Best regards,

Charles

The PPS directly out of most GPSDOs is too fast for sound cards.  But
once you stretch it, there is another problem.  Assuming 5v logic, and

a time period that depends on the post-capacitor DC resistance inside
the sound card.  It might decay fully (back to 0v) during the pulse, or
less than that.

The falling edge of the pulse will generate a negative-going spike with
a peak negative voltage of [decayed voltage after leading edge minus
5v].  This could be anywhere from just slightly negative to the full
logic supply (if the post-capacitor voltage decays fully before the
falling edge occurs).  The same would be true for 3.3v logic,
substituting "3.3" for "5" above.

These peak voltages are way outside the input range of most sound cards,
so the positive spike is almost certainly going to overload the ADC,
with unpredictable (and, very likely, unfortunate) results.

At the very least, you will need some sort of sound-card oscilloscope
program so you can see what the sound card is actually capturing.  Then
you can start shaping your trigger pulses (with voltage clamping and
possibly LP filtering) to give predictable and stable results.

You may even be lucky enough to see brief periods of phase reversal on some

Re: [time-nuts] Lucent RFTFm-II-XO

[Bob Camp]

Hi

If the PPS is going to run into a run of the mil sound card, the pulse width 
likely will need to be > (1/20,000) s. That will require a one shot to do. The 
Lucent PPS is a bit narrower than that, as is the output of a lot of GPSDO’s.

Re: [time-nuts] Lucent RFTFm-II-XO

[Bill Riches]

Hi Bob,

If you could,  would you see if you can take the pps out of your lucent box and 
use it to sync the pc sound card clock via continuous calibration for  using SL 
for fx measurements.  Maybe by lucent box pps output is bad.

15625 from 3586 goes in one channel and pps goes into the other channel of the 
sound card and SL does its magic.

Be careful of the pps output from the dual lucent boxes.  Tried to use it to 
sync SL and found that it is a weird non-standard pulse and would not work even 
with a pulse stretcher as it looked too narrow.  I use the pps output from a

It's in the mail archives.  Google for something like >time-nuts RS422 pinout<

If you are interested in timing, you want the PPS signal too.  (It won't be 
great over USB, but it might be fun to play with.  You can get your own hanging

Hi,

The USB to RS422 adapter arrived.  According to the online manual for the 
adapter, the RS422 signals I'm looking for are:
Send A+
Send B-
Receive A+
Receive B-

Is there a pinout posted somewhere  for the Lucent box RS422 D sub 9 connector?

Thank you.

Re: [time-nuts] Lucent RFTFm-II-XO

[Bill Hawkins]

As to what you would see, find the manual for the Motorola receiver for
details. I don't have the link, but somebody else does.

You get some info about the device and info about each satellite.

You can use a 422 to USB converter or clip on either wire with a digital
scope that decodes simple serial streams, like PicoScope.

Hi

These days, a RS-422 to USB adapter is a sub $20 item, even from a “name brand” 
outfit with real
drivers. . If you shop a bit, you can get some dirt cheap USB to 422 adapters 
at the risk of having

Re: [time-nuts] Lucent RFTFm-II-XO

[Chris Waldrup]

Hi,

Regarding the Lucent box- I wanted to let everyone know that once it locked to 
satellites, I have a 10 MHz out. 
The output was a square wave with some ringing, but I built a three element low 
pass filter and now I have a really nice 10 MHz sine wave. 
Thanks to all!

Last question I see it has a RS-422 output on one of the connectors. If I 
build or buy a 422 to 232 converter can I expect to be able to view the unit's 
data output with something like Lady Heather or Tboltmon? Or at least see an 
output with Hyperterminal?

Thank you.

Hi

One might *think* a redundant system would work fine with the plug yanked. 
In this case …. nope. It needs to have a dummy connector on it to get the device
running. I agree that this is an “interesting” way to do it. Regardless of 
that, they
did the units need the signals from the other box (or fake signals)  before 
they 
will do useful stuff.

Fake connections? Isn't a redundant system supposed to allow one box to
be disconnected?

Hi

If you only have one box, you need to be sure the "fake" connections on
the interconnect are correct. If they are not, you will not get it to
operate correctly. 

There also is a survey process if you have not had it running in your
location before. That could take a few hours to a few days depending on
your antenna.

Hi

If you only have one box, you need to be sure the “fake” connections on the 
interconnect 
are correct. If they are not, you will not get it to operate correctly. 

There also is a survey process if you have not had it running in your location 
before. That 
could take a few hours to a few days depending on your antenna.
