[time-nuts] Bad TBolt Crashing LH?

Sounds like a serial port driver problem. I started having some issues with my Prolific adapters in Win XP after installing some EEPROM burner software. It shows up as garbaged data after typically a day or two of continuos use. It could also be related to another issue in v5.0 if the Tbolt

Re: [time-nuts] SA22.c and Lady Heather

hi i was prepping for some machine shop work on a heatsink for the SA22.c. there seems to be an error in the designers reference and user manual on page 22. the bottom view drawing at the far low right shows a measurement of the distance between the edge of the board and the hole just below and

Re: [time-nuts] Bad TBolt Crashing LH? - NOT TBOLT

Hi Bob, Mark, Tom, Thank you so much for your advice and support. My TBolt is fine. Using Bob's suggestion of a serial Y cable and 2 PC's running LH... I had one PC crash with evolving gibberish on the LH screen while the other PC running LH showed stable solid performance. So it either is

Everyone... We're going to take this issue off-list for a while. Mark (LH author) and others will work this out with Jerry by email and report back when all is known. Thanks, /tvb Moderator, http://leapsecond.com/time-nuts.htm - Original Message - From: "Jerry" To:

Re: [time-nuts] Bad TBolt Crashing LH?

My problem isn’t subtle... I get a Windows 7 popup that LH stopped working. When I look at the last log entries, there is marked corruption so ROM, OSC, POW are all major critical errors listed as bad. I have both PC's running now so will let them run at least until something crashes. Now

Re: [time-nuts] Bad TBolt Crashing LH?

Bob, Great idea... I now have my TBolt connected to 2 different PC's via a serial Y cable using two different USB-Serial adapters.. both PC's running LH and logging in background. Now to see if both crash simultaneously. Jerry, NY2KW -Original Message- From: time-nuts

Re: [time-nuts] Bad TBolt Crashing LH?

Hi I’d just set up your favorite terminal program (PUTTY or whatever ) on the second PC and let it do a log file to disk. Then go back and look at the “problem time”. If all of a sudden the lines are half as long or twice as long as they should be …. you found the problem. The kind of stuff

Re: [time-nuts] Bad TBolt Crashing LH?

Hi Bob, I have a Y 9pin serial splitter somewhere. When you say log do you mean using LH to write a raw file on both PC's simultaneously? Is serial comm between LH and PC all receive only - no handshaking that would get messed up with a split Y serial cable? Jerry, NY2KW -Original

Re: [time-nuts] Bad TBolt Crashing LH?

Hi, Not to flood the list with traffic, but as this is probably an issue that many list members run into I'll speak up. FTDI has been very good. We've run everything from their very first chips through USB 3 hardware, and never had any problems. The TTL-232R series of cables are also very

Re: [time-nuts] Bad TBolt Crashing LH?

Hi If you have a second PC, there’s a real quick shortcut. Make up a Y cable and log the output of the TBolt on the second machine. If the TBolt really *is* sending junk, you’ll see it. If not, the TBolt is ok. Swap the machine that is logging, if the same thing is still true, it’s not the

Re: [time-nuts] Bad TBolt Crashing LH?

Thanks Ken, yea that was fun until i read aboit disabling it. Unfortunately not the problem. I swapped PC's and still happening so i am ledt with power supply, usb-serial adapter or Tbolt problems. In process of elimination now Jerry Sent from my iPhone > On Aug 30, 2017, at 6:35 AM, Ken

[time-nuts] [OT] Re: Bad TBolt Crashing LH?

Yep, Prolific got badly hit by the counterfeiters. So, they depreciated the use of all the early generation chip-sets (even legit ones!) and had MS push out updated drivers to enforce that. That's why it "appears" to be a Windows update problem that stops many older Prolific based adapters

I came across an HP Z3801A that I had not unpacked, been sitting in the box for 11 years !! Plugged it in and in about 30 minutes it showed a GPS Lock !! Now, the software I have so far found was designed in the Pre- Cambrian era and will not work on my 64 bit WIN10 system. Is there any

Re: [time-nuts] Bad TBolt Crashing LH?

You also want to disable the "Microsoft Serial BallPoint" mouse in Windows Device Manager. If left enabled it causes your mouse pointer to jump all over the screen every time the TBOLT sends data to the computer; about once/second. That was "fun" the first time I encountered it. It looks like

Re: [time-nuts] Bad TBolt Crashing LH?

For FTDI serial ports, in addition to ensuring that USB suspend is disabled in advanced power properties, it's worth disabling Serial Port Enumeration in the advanced properties for the com port. This will help prevent FTDI ports with data being gratuitously sent to them from being assumed to be a

Re: [time-nuts] Trimble Thunderbolt no longer determines the correct date  

Hal, I suppose your opinion is correct. A friend has found the same problem with an HPZ3016A GPSDO. The solution was to resetting the internal counter inside the Motorola GPS module. To do this , the friend has removed the GPS module and communicate using his proper serial port to reset
