[time-nuts] Tbolt monitor software

I had a similar (but probably worse) failure of one of my Tbolt's.  When I
went back to turn it back on, there was no response on the software.
Everything was a 'question'.  The 10 MHz output was there but it never
'locked' as compared to my other GPSDO's (although it was EXTREMELY close)
and there was no 1 PPS output.  I suspect a power issue to the processor and
GPS receiver but I have not had a chance to track it down so far.  I did
open the unit and 'sniffed around' but I did not see any obvious issue.  My
plan is to set up an operating Tbolt and the 'dead' unit, side by side, and
start tracing levels and voltages.

I would be very interested in anything you discover.

Hi,

Yes, I can see alarm status and changes when unplugging antenna etc.

As mentioned the unit actually works, just no data certain displayed.

Did you select the right comm port? I power mine off a lot and it has
always come back.

Hi group,
 
A strange situation has led me to ask a question about the Tbolt GPSDO
and the Trimble Thunderbolt monitor s/w version 2.6.
 
While re-arrangement of the shack, it's been idle for 3 weeks, Tbolt
turned off. After turning the unit on and letting it settle some 2 hour,
I connected the monitor program and found the following that I can not
explain and correct:-

*   All SV and AMU have question marks
*   Product info has questions marks
*   the ability to see tracking status is blank.

When last used, some 2 months ago to show a friend, the relevant display
data came up, no issues. Further more, position, critical and minor
alarms are green, disciplining status section such as DAC voltage DAC
value mode and even it's 10MHz out etc etc is fine compared to my trusty
Rubidium standard.
 
Has any one seen this before and is there a setting that may have
inhibited this feature?
 
I have a screen shot, however it may be to large to attach, so let me
know if this will help, I will be glad to forward it to some one with
much more knowledge.
 
Thank you in advance.
 
Regards,
