Re: [time-nuts] Question about HP-53132A decimal display

[Tom Van Baak]

Mark,

It should be in the hidden "Utility menu" which you access by holding Recall 
during power-up.

Not sure what you mean by enabling commas vs. swapping commas.

For more details see page 2-57 when you google: 53132a user manual
or look for hp / Agilent / Keysight document 53131-90055.

[time-nuts] Question about HP-53132A decimal display

[Mark Sims]

I recently got in a 53132A with what I think is fairly early firmware (it's 
tied up doing some measurements right now so I can't check the version number). 
  All the photos of the 53132A that I have seen show it with commas separating 
groups of 3 digits after the decimal point.  Mine does not do this.  Is there a 
menu option for enabling the commas (not the option for swapping commas and 
decimal poimts) or was this feature added in a later firmware revision?

Re: [time-nuts] Thunderbolt Monitor Kit by KO4BB

[Chris Albertson]

The Raspberry Pi idea is good because for your $100 it can do a few other
tasks at the same time.

It can run LH but also maybe she other services like  NTP,  a small web
server and also a WiFi based backup server that backs up any notebook
computers you have (it such a hassle to plug in an external drive to a
notebook that few people do it.   So I have mine do an hourly backup over
WiFi.)

I have a Pi3 on my desk right now and yes, it is more than powerful enough
and would be under utilized even with a half dozen light weight servers
running.

So a $100 t-bolt monitor is rather expensive but if you can get four of
five other functions at the same price, maybe worth it.

Re: [time-nuts] Problems with TAPR Oncore M12+ kit

[Gregory Beat]

Yes, agree.

Since your TxD LED is not blinking (~1 sec), then the Oncore receiver is not 
transmitting data (TTL serial).

PWR—This LED should always be GREEN when power is applied to the GPS Kit.

TxD—The TxD indicator provides the user with visual feedback concerning data 
output from the receiver. The TxD LED will momentarily flash RED whenever the 
GPS Kit is sending GPS data to the host computer.

RxD—The RxD indicator will flash RED whenever commands are received from the 
host computer.

1PPS—The 1PPS indicator will flash RED whenever a 1PPS pulse is output from the 
GPS receiver. There are 2 user defined Modes of operation for the 1PPS LED 
indicator, that can be configured/programmed (Oncore commands).

Has anyone else received a TAPR unit they can't get to work?
I got my unit finally boxed up a few weeks back. 
The PPS LED flashes and power LED and RXD LED's light but the TxD doesn't.
No serial communications, unfortunately. 
I've found a Oncore M12 board on eBay coming from China and this should come in 
a few weeks.

hi chris

i could not get TXD to flash till i connected the unit to Lady Heather

once the unit was communicating with the LH program (much serial wizardry)
all was well.

A modification on the above option - instead of a dedicated display, 
enable the VNC server on the RPi and use RealVNC on your main computer 
as the display for the RPi.  I'm working on this as the setup for my 
second TruePosition board.


It works pretty well.  Here is a screen-shot from my desktop PC using 
RealVNC into the VNC Server on my RPi running Lady Heather, but without 
the TruePosition hooked up yet:

[time-nuts] TruePosition on the Arduino

[Ben Hall]

Good afternoon all,

I've been working for a while to write my own Arduino sketch to control 
and interface the TruePosition GPS units.  This morning I added in logic 
to allow the switching of the display pages using a push button between 
Arduino Uno pin 11 and ground.  (which isn't covered in the source file 
comments, ooops, I need to add that)


Everything seems to be working.  You can find the source code at the 
link below, but you must promise not to laugh too hard at my lack-luster 
programming skills...this is my first "real" Arduino program other than 
the usual "hello world / blink an LED" type programs.


Plus, while various versions have been working here for a couple of 
months now, your mileage may vary, etc...  I've only seen it barf and 
hang up once and I'm pretty sure that something conductive got dropped 
onto the TruePosition board by my 11 year old son.  (ooops!)




Some known issues / limitations:

0)  I need to update the notes in the source to add the following:

	a)  the display pushbutton goes between pin 11 and ground and is 
normally open.


	b)  the Packrat documentation uses the RS232-level output and needs the 
jumper on on the large header.  This code uses the 3.3V level TTL serial 
and you've got to remove the jumper else the program won't be able to 
issue the $PROCEED command.


	c)  the display pushbutton cycles between three displays:  the first is 
a general status display with date, time, and status, the second is 
satellites 0 to 3, the third is satellites 4 to 7.


1)  You've got to power up the TruePosition board and wait for it to 
"boot" and blink the LED before starting the Arduino up.  Else you may 
need to reset the Arduino after the TruePosition is booted and blinking.


2)  It is targeted towards a 20 character wide, 4 lines deep LCD display 
of the I2C / SPI variety.  These aren't real easy to find; I made up my 
own using a 20x4 LCD display and one of the conversion boards either 
from Amazon or eBay, I don't recall.


I may rework the code for a 20 by 2 display as my eventual package for 
this unit will be 1U which is too short for a 20 by 4 display...but a 16 
by 2 display just doesn't have enough real estate IMHO.


3)  It cannot command a survey.  You've got to manually hook up to the 
TruePosition using a computer and send the survey command via a terminal 
program like Putty and let it finish before you can use my code.  I'll 
probably add in a survey command and monitor function but may be some 
time before I do this.


4)  While the program does pull in what I believe is a DOP value from 
the EXTSTATUS message, it doesn't display it anywhere.  I need to create 
a fourth display page with DOP on it or fit it in elsewhere.


And that's about it.  Suggestions to the code are welcome.

thanks much and 73,
ben, kd5byb

Re: [time-nuts] Problems with TAPR Oncore M12+ kit

[Gregory Beat]

Chris -

I was not aware that you were having issues with the TAPR Experimenters Kit.
I am finishing a DIY GPS kit build from "assorted parts sources" for Jim Pruitt.
Jim missed purchasing the TAPR kit in May 2017 (sold out before he ordered).
--
I acquired ($) a Synergy SynPaQ/E carrier board with a dead M12+ receiver.  
Since I happen to have a couple spare Oncore M12+ boards (inventory, working), 
it was just a matter of swapping those receiver boards.
--
You need to be careful in selection of the GPS antenna, since there are a wide 
variety on the surplus market: Passive (no pre-amp); Active with different 
voltage requirements (12, 5, or 3.3 VDC) from GPS receiver.
At the electronics bench, I try to use 5 Volt antennas (or 3.3V that are 5v 
tolerant) with similar GPS receivers (5V preferred).

Chris, are you sure the RX light is blinking and not the TX?  When you turn it 
on, you should see the TX light blinking and the PPS with Power on as well.
