Re: [time-nuts] Motorola GPS Antenna?

[Art Sepin]

Clint,

You have found a Motorola Timing2000 GPS antenna. Please see the Timing2000 GPS 
Antenna Specifications and Timing2000 GPS antenna technical presentation on 
this page:
http://www.synergy-gps.com/index.php?option=com_content=view=42=89

This was a popular, Motorola designed GPS antenna manufactured by Yokowo of 
Japan for Motorola's CDMA cell site timing products and for distributors like 
Synergy for general sales. After Motorola exited the GPS business in June of 
2005, Synergy continued to sell this design as a Synergy Timing3000 (no 
Motorola Logo) until it went EOL many years later.

Re: [time-nuts] Need Oncore connector info.

[Art Sepin]

The UT+ 10 pin AMP connector part number is listed in section 3 of the UT+\GT+ 
User's Guide Section 3 on page 3.2 here: 
http://www.synergy-gps.com/index.php?option=com_content=view=35=60

Motorola did not document I/O connector detail in the M12+ User's Guide except 
to say: " Straight, 0.050" [1.27mm] Pitch, 10 Pin Data Header." So, Randy 
Warner produced a short App-Note on the subject back in 2005. It's available

Re: [time-nuts] TAPR kit- Success!!!!!

[Art Sepin]

Group,

I reviewed the TAPR GPS Kit documentation and realized that nowhere did it say: 
"If the TxD  indicator does not flash, it means the M12+ is waiting for a 
command from the host computer." That sentence is now included in the revised 
GPS Kit document and will be available tomorrow on this page: 
http://www.synergy-gps.com/index.php?option=com_content=view=54=73

Here is the revised paragraph in full:
TxD— The TxD LED will momentarily flash RED whenever the GPS Kit is sending GPS 
data to the host. If the TxD
 indicator does not flash, it means the M12+ is waiting for a command from the 
host computer. After the internal RAM backup battery is fully charged (24 hours 
of continuous operation) the SynPaQ/E will remember the receiver’s setup 
through a power cycle – e.g. user selected output messages, message output 
rate, antenna mask angle, etc.

The RxD indicator only flashes when setup commands are received from the host 
device. Once the GPS Kit is set up, the RxD doesn't flash unless a new command 
is received.

Synergy's SynTAC test and diagnostic software automatically initializes the 
M12+ included in the GPS Kit. After this setup is complete, the TxD indicator 
will flash at once per second:
http://www.synergy-gps.com/index.php?option=com_content=view=185=196
 It's not necessary to purchase SynTAC to accomplish automatic initialization 
of the GPS Kit since it is fully functional through a 30 day sample period.

Apologies for any inconvenience!

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

[Art Sepin]

There is a brief description of the parts included in the kit here:
http://www.synergy-gps.com/index.php?option=com_content=view=54=73
It includes end plate dimensions and hole locations, etc. We have added 
paragraph 5 to the document as follows. It will be on the web site tomorrow.

Art


5. The original SynPaQ/E motherboards supplied with the Motorola M12+ based 
TAPR GPS Kit were designed to accept the larger form factor Motorola VP, GT+ 
and UT+ Oncore Series GPS receivers. The mounting holes for the VP, GT+ and UT+ 
receivers, and the required 5 VDC supply, are already part of the motherboard. 
Simply add the larger 10 pin header and supply the slightly longer 440 x 0.250 
receiver mounting standoffs. According to Motorola GT+\UT+ TRM0003 User’s 
Guide, the mating Power/Data Connector is a 10 pin (2x5) on 2.54 Centers - AMP 
#104326-06 (Samtec has equivalent).

Is there a way I can help with this project?  If I had the specs to look at, 
maybe I would be able to run off a bunch of plates.  If we could batch them up 
I would do them for the cost of shipping.

Does anyone have a dimensioned print, picture, cad drawing of the plates?

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

Folks,

The TAPR GPS Kit documentation has been updated and revised for clarity (I 
hope). it includes details for purchasing end plates and also dimensions 
required to fabricate end plates. The TAPR GPS Kit document, and a motherboard 
schematic for reference, is now available on Synergy's "GPS for Scholars" page:

Interface Boards for Motorola (and Garmin) receivers have been discussed (and

discontinued GPS kits, can be seen on the left margin.

Simple interface board schematics (Serial Level converters, and voltage 
adjustments for external antennas/ 3.3 or 5 V) can be found throughout the 
Internet since mid-1990s.
Numerous radio amateurs DIY their own (breadboard) or sold small interfaces at 
hamfests (1996-2006), until newer GPS solutions became surplus (and smartphones 
with built-in GPS appeared after 2007).

Doug McKinney, KC3RL (SK, December 2006) offered interface boards for the 
Garmin (GPS-25) and Motorola receivers until about 2005.  I have one of Doug's 
boards in my GPS parts box.  These were sold by TAPR until their inventory was

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

[Art Sepin]

Norm and Bob,

The M12+ GPS receivers mounted on the motherboard are indeed the timing units. 
Chapter 5 of the Motorola M12+ User's Guide is here:
http://www.synergy-gps.com/images/stories/guides/m12+userguide.pdf
The binary commands and output messages, including timing related commands, are 
in Chapter 5 starting on page 59.

The M12+ timing receiver can also be used for navigation applications - simply 
don't use the Position Hold mode. The main difference between the M12+ 
navigation receivers and the M12+ timing versions is that the navigation boards 
have a faster TTFF.

Motorola didn't refer to the M12+ timing version as "M12+T" That designation 
was used by Synergy, and others, to clearly differentiate the timing version 
from its navigation counterpart.

We recently forwarded information to TAPR on where to purchase front and rear 
end plates for the housing and also dimensional information on the hole sizes 
and locations. Until that info is available from the TAPR.ORG web site, we'll 
be happy to forward that information to anyone interested off list.

Have a few +T's. Don't need another timing rx. Would take a few positioning

Re: [time-nuts] Z3801A gps week rollover

[Art Sepin]

Timing product manufacturers used a variety of OEM GPS timing receivers over 
the years including the Motorola Oncore series. The 1024 Week-Roll-Over dates 
for Oncore receivers, computed from the firmware version compile date, are 
listed here:

http://www.synergy-gps.com/images/stories/pdf/motorola%20oncore%201024%20week%20roll.pdf

Synergy is adding 8 channel Motorola binary commands to our u-Blox based 
SSR-6Tf OEM timing receiver that plugs into an Oncore 8 channel slot - 
available "soon."

It's probably 1024 weeks since a date was built into the firmware.

It's like the year 2000 problem.  If you aren't worried about old people and I 
tell you somebody was born in 03, you can assume that's 2003 rather than 1903.  
For GPS, a handy value for the cutoff is the date the firmware was built.  Any 
date that looks like it is older than the firmware is probably off by a 
rollover.

Re: [time-nuts] uBlox (US) reseller recommendation?

[Art Sepin]

Nick,

u-Blox does not use distributors or resellers in the Americas so they recommend 
using their web site ordering system. 

Synergy has excess inventory of the u-Blox LEA-6T GPS flash module. The P/N 
LEA-6T-1-000 is the more expensive flash part that can be updated if new 
firmware becomes available. We can part with these at $16.50 each in 250 piece 
reels or $21.50 in minimum quantities of 10 pieces. 

We have an order minimum of $50 and we support a 10% discount for 
non-commercial use like Hams, experimenters, educational pursuits, etc. We are 
a customer of u-Blox and not an authorized reseller or distributor so we do not 
provide technical support and cannot pass through the u-Blox warranty. For that 
go to: supp...@u-blox.com.

If this is of interest, please contact Gina Aspeytia at: g...@synergy-gps.com. 
I Apologize in advance for the overt commercial style message but I thought 
this might be of help and interest - Thanks!

Re: [time-nuts] Z3801A recovering

[Art Sepin]

Joe,

In a way, the VP Service Note: 
http://www.synergy-gps.com/images/stories/ShopTalk/vp_service_note.pdf ties 
into the VP Oncore Startup Note because it is associated with the VP Oncore's 
Pendulum oscillator.

Back in the late nineties, some customers noted that VP Oncore signal strength 
diminished over time when operating 24/7/365. Motorola determined that the 
decreased sensitivity was caused by crystal aging which is normally corrected 
every time the VP is power-cycled. Power-cycling lets the VP write the 
appropriate, aged, oscillator characteristics to EEPROM to reset the VP to its 
expected performance range. If you note signal strengths being reduced over 
time, then it would be wise to power-cycle your VP -  Otherwise, just let it 
run.

Thanks for the link. Very useful information. I also read the 'VP Service note" 
posted there. Is that note also referring to the oscillator, or some other 
component that needs periodic recalibration.
In any case, it seems that they are recommending that we power down our GPSDO

a while to stabilize again.

Now that I finally have some replacement Oncore VP modules, I've been able to 
do some tests and comparisons. Using WinOncore 12, I tested the VP's that I got 
from Pete. Then I compared the old module from the Z3801A. The old module seems 
to be deaf. It reports that it sees plenty of satellites, but didn't lock onto 
any when left running overnight.

Either tonight or tomorrow night, I'm going to put one of the tested VP modules 
into the Z3801A and see how things go. I will also be replacing a few caps that 
tested good, but looked suspicious. There were signs of outgassing on the power 
supply board.

While waiting for Pete to make the VP modules available, I bought two
UT+ modules from ebay. After reading various documentation, I found
out that you can't use a UT+ in a Z3801A. It's a shame, because the
UT+ seems much more sensitive and locks much quicker than the VP
modules. I may be able to use the UT+ modules elsewhere.

Re: [time-nuts] Z3801 Update with VP-Oncore 8Ch receiver

[Art Sepin]

Greg,

Progress on designing M12x clones, like Dan's board, are really impressive. 
More models will give users a wider choice from which to choose a replacement. 
On that note, Synergy will also be rolling out an SSR-M8F Multi-GNSS timing 
board (uses LEA-8MF Module) that's also plug-compatible with the 40 mm x 60 mm 
M12x footprint.

Also, contrary to rumors that have circulated, the M12M Timing receivers are 
still very popular and shipping daily. No EOL has been announced. There are, 
however, obvious advantages in employing u-Blox based timing devices for faster 
TTFF and greater sensitivity for users seeking those features.

Re: [time-nuts] Z3801 Update with VP-Oncore 8Ch receiver

[Art Sepin]

The first 8 channel, B3 series Motorola VP Oncore was introduced in late 1996 
and was followed by the B4, which included a better RF front end filter, and, 
finally, the B8 which used a revised PC Board layout for lower noise operation. 
 All of these 8 channel VP Oncore receivers included a backward compatible 6 
channel mode. See the VP Oncore Command Reference here:
 http://www.synergy-gps.com/images/stories/pdf/vpcommands.pdf

The Synergy Adaptor Board product, with an M12+ or M12M GPS receiver, will not 
function in products expecting a 6 or 8 channel message. That’s because HP, and 
products from other manufacturers, are sending either a 6 channel @@Ba command 
or an 8 channel @@Ea 8 channel command to the receiver and, depending on the 
specific command sent, are expecting either a 6 channel @@Ba or an 8 channel 
@@Ea reply message. The 12 channel M12+ and M12M receivers do not have a 6 or 
an 8 channel backward compatible mode so the @@Ha 12 channel messages are not 
requested and are not recognized by HP and other timing products.

When used with an Adaptor Board, Synergy’s new u-Blox based SSR-6Tf GPS 
receiver board is mechanically and electrically plug-compatible with the older 
VP Oncore units. It also contains important 12 channel Motorola binary timing 
messages and some of the basic 6 and 8 channel command\reply messages needed 
for 6 and 8 channel based timing products (HP and others). Firmware updates for 
6, 8 and 12 channel messages will also be available. Until Synergy's new web 
site is up and running, we can respond to SSR-6Tf questions or comments off 
list.

For VP Oncore receivers that don't seem to work, the B3, B4 and B8 VP Oncore 
receivers included a power saving idle mode for navigation applications. On 
occasion, a timing user would call to say their VP Oncore was not working. 
Nearly always the cure was to use the @@Cg Position Fix\Idle Mode Select 
command to put the receiver back to Position Fix Mode.

This brings up a question that I have been wondering about.  Has anyone tried 
using one of the Synergy M12/adaptor board assemblies as an update in the Z3801 
or similar unit?  If the original firmware just ignores the extra data, perhaps 
the Synergy unit might work? They are quite inexpensive on the used market.

See:

https://na01.safelinks.protection.outlook.com/?url=http%3a%2f%2fwww.synergy-gps.com%2findex.php%3foption%3dcom_content%26task%3dview%26id%3d173%26Itemid%3d115=01%7c01%7cart%40synergy-gps.com%7cb4b40e483fe146c6a36608d3303c6ff1%7cc81f9fdec0e04d8c95779afaa0cad9ed%7c1=7Nk8Dj%2bE2H6yNAm2tWXnvCetomDrfxb1rITrKgxRgRg%3d

As a further upgrade, might it be possible to replace the M12 receiver unit on 
the Synergy board with a Jackson Labs M12M replacement receiver?  While the 
additional data would be lost / ignored, the superior characteristics of the 
Jackson Labs unit could prove helpful.

Thanks for any information.

Re: [time-nuts] Synergy-GPS SSR-6tru Problem Resolved

[Art Sepin]

Bob,

Once in a while a mea culpa is required and we're posting it here so everyone 
understands our commitment to the users of Synergy's products. 

The Original Synergy Adaptor Board was designed to allow Motorola's newer 3 
volt 12 channel M12+ to plug into an older 5 volt 8 channel UT+ slot. That 
product worked for hundreds of users over the years until (we found out through 
your personal aggravation and agony) the recent introduction of Synergy's SSR 
series of u-Blox based precision timing boards. 

To make sure that the Synergy UT+ Adaptor Board issue is put to bed properly we 
asked for an external, formal technical review of this product that was 
introduced fourteen years ago.

The reviewing engineer's first comments were Ouch! This will not work.  And, 
no, the SSR boards do not work the same as the M12 boards on the Synergy 
Adaptor Board. The M12+ and M12M receivers have separate serial ports for the 
two functions (Receiver command RxD and DGPS RxD input) so it does not matter 
what you do with the RTCM port, pin 5 on UT+ connector and pin 8 on the 
M12+/M12M connector, if not in use with an M12x receiver.

The SSR boards, however, had to combine the two serial data streams expected 
by the M12x navigation receivers into one because the u-Blox receiver modules 
only use one serial input port for both receiver commands and DGPS correction 
data. The Synergy Adaptor Boards use a simple gate combiner circuit that worked 
well when using the M12+ or M12M but left Synergy open to this problem when 
using an SSR. Both serial lines on the SSR board, pins 2 (Receiver RxD) and 8 
(DGPS RxD) are pulled high on the SSR board so open pins are OK but they must 
not be grounded.

The solution is for Synergy to make a UT+ Adaptor Board part number available 
to users who only want to test the features of SSR timing receivers.

That new SSR only Adaptor Board part number, which we'll have available in a 
few days, will remove R3 (4.7K) and R4 (6.8K) from the adapter board and the 
compatibility issue will be resolved. In the interim, other users can pull pin 
5 of the UT+ connector high (+5V) as you did. 

We apologize for the confusion and frustration, Bob, and thank you for the 
valuable feedback!

Art Sepin

Hi Tom,

I think that an offline conversation with Dusty Morris may have pointed out the 
root cause.  The SSR-6tru board uses 3V logic, but the Motorola Oncore boards 
use 5V.  So the Synergy M12 adapter has to do the level shifting to protect the 
receiver.  It does this for input signals by using a voltage divider composed 
of a 4.7K resistor on top  (for the 5V input) and a 6.8K resistor on the bottom 
to ground.  The center tap of these two resistors goes to the receiver.  
Normally we would expect an open TTL pin to be a logic high.  But, in this 
case, an open pin to the 4.7K resistor on top leaves the 6.8K resistor to act 
as a pull-down on the receiver's input pin.  At least that's my speculation.  
I'm no EE.

h/w and SHOWTIME.EXE s/w, in the same way we use Trimble's Thunderbolt h/w and 
Mark/John's HEATHER.EXE s/w today.

As a reminder, I received an SSR-6tru receiver from Synergy, along with their 
M12 adapter, which allows you to plug it into a slot for an Oncore GT+, UT+, or 
VP. I was unable to get the receiver to respond to any commands from the u-blox 
u-center software.

After a lot of troubleshooting, I discovered that pin-5, the DGPS IN pin, 
must be brought to a logic level high in order for this assembly to work. If 
it's low, apparently anything going into the board on the Rx line is simply 
sent back out on the Tx line and not passed to the receiver. I've never owned a 
GT+ or a VP, so I wasn't aware that a logic high was needed on this pin. The 
UT+ works just

Re: [time-nuts] Synergy-GPS SSR-6tru problems

[Art Sepin]

Bob,

One of the most obvious things is that the UT+ uses 8 channel Motorola binary 
commands with the @@Ea Position Status Data command producing the most useful 
data at start-up. The UT+ did not have a NMEA message capability.

Another obvious thing is that the UT+ is an 8 channel device and the SSR-6T 
responds only to 12 channel Motorola binary commands. 

A firmware update including the 8 channel @@Ea message (like the UT+) will be 
available in the coming months. A 6 channel @@Ba command is also being added so 
that users of legacy HP timing products that used the old VP Oncore will have 
an up-grade path. Hope this helps.

I got one of these recently, along with the adapter board.  This is the ublox 
only version, and I am using u-center version 8.11 software.  I am unable to 
make it work properly.  The NMEA section happily sends out messages, but I 
cannot get anything else to work.  e.g. it ignores the commands to turn off 
antenna power.  It ignores the command to put it in Survey-In mode.  Nothing is 
displayed when monitoring the SVIN field.  I sent the board back and received 
one that they have tested there at the site.  Same story.  When I plug my UT+ 
into the same connector in my GSPDO, it works just fine and responds properly 
to commands from WinOncore12.  I have used both a serial port adapter and a 
USB-adapter to drive the TTL lines to the board.


So, there is something wrong at my end, and it's probably something so trivial 
that no-one would think to mention it.  Has anyone tried this board?  Can you 
think of any setting that's inherently obvious to the most casual observer 
that a newbie could repeatedly overlook?  For example, is there some first 
setting that you always do in u-center to shut down the NMEA and turn on the 
UBX, but the setting does not save on the board and the u-center software 
always overrides it?


The configuration is this:  The adapter does the 3V to 5V stuff, and plugs into 
the same connector as my UT+.  The antenna lead is connected to a non-powered 
port on my GPS Source splitter.  The splitter connects to a puck in the attic 
via RG-6.  The SNR of the received signals is in the 20-50 range on the 
u-center display window.  I have tried driving a different puck directly that 
is in my lab room.  No change except for lower SNR values.

Re: [time-nuts] Z3801 Replacement GPS Receiver Card

[Art Sepin]

WinOncore12 was Motorola's first Windows application coded for the
original M12 and, in 2001, the new M12+ timing receiver. WinOncore12,
and the later SiRF Oncore application, only recognize 6 and 8 channel VP
Oncore commands to the extent that they are common with the M12x
receivers (not that many).

Motorola only offered the DOS based GPS Controller software back in
1997 so Synergy commissioned Rick Hambly at CNS Systems to produce a
sub-set of his TAC/32 Windows controller application for us - it's named
SynTAC. SynTAC (like TAC/32 and TAC32Plus) automatically recognizes and
initializes every 6, 8 and 12 channel receiver produced by Motorola from
1992 to 2005 and ilotus M12M receivers from 2006 to present. This
includes the original 6 channel PVT-6, 68 channel Basic Oncore, 68
channel VP Oncore, etc., etc.

Since 1997 Hundreds of Hams, experimenters and educational institutions
have downloaded the fully functioning 30 day evaluation version of the
SynTAC application (without purchasing the product) to automatically
setup and test Oncore receivers that didn't seem to work properly or
were behaving oddly due to conflicting setup commands.

OK, you can test a VP Oncore GPS receiver alone if you have a mean to
translate the TTL serial port to a regular RS232 for the PC. This can be
done with a MAX232 chip (or equivalent). Then the pinout (refer to the
engineering notes previously mentioned, page 9): pin 2 and pin 3 are the
main power supply (2: +5B and 3 GND) and the serial port pins are pin 8
TX and pin 9 RX. The TX pin must be routed to the TTL to RS232
translator and then to the RX of the PC (pin 2 if a DB9 is used or pin 3
if a DB25 is used). Pin 9 comes from the translator and from the PC TX
pin (pin 3 DB9 or pin 2 DB25). The WinOncore software can be used to
test the receiver. Don't forget to connect an external (that is on the
roof)  GPS antenna and prepare your 'scope for the PPS on pin 6. The PPS
should be pretty visible as it is 200mS long (see page 7).

Motorola offered an 8 channel GPS chipset and also a 12 channel chipset
based on the MC2003. A separate RF Oncore GPS receiver front end (PWA
Board) was also sold in the late nineties. These products were only
available to volume users (50 K pieces and up).

I'll review what we have stored in the Motorola archives. The problem is
that almost all of this early, legacy GPS receiver documentation was
only available in paper form.

Re: [time-nuts] M12M Sensitivity

[Art Sepin]

Steve,

The short answer to the question of M12M GPS receiver sensitivity is:

Min acquisition signal level = -128 dBm (at module connector) 
Min track signal level = -135 dBm (at module connector) 
Max track signal level = -30 dBm (at module connector) 

The background is that the sensitivity figures for the Motorola M12+ and

the later Motorola designed M12M being produced by iLotus were never
published for some reason (they were also not included in the PVT-6,
Basic Oncore, VP Oncore or UT+ Oncore User's Guides). In place of
sensitivity figures, the respective User's Guides included a page headed
Antenna System RF Parameter Considerations. In the case of the M12M
User's Guide, available at http://www.synergy-gps.com, refer to page 66.
I'm mentioning this because there is a mistake on page 66 which
erroneously lists M12M gain range as 18 - 36 dB (which is the M12+
spec). The actual gain range for the M12M is 10 - 50 dB (which is shown
correctly on the M12M datasheet).

In an effort to avoid blatant commercialism, the new iLotus TX Oncore 
timing module, available in late March, has the following published
sensitivity figures:

Min acquisition signal level = -146 dBm (at module connector) 
Min track signal level = -159 dBm (at module connector)
(Max track level not published)

The TX Oncore datasheet, found on our web site, includes Motorola binary
Emulation for popular timing commands.

Re: [time-nuts] GPS pcb IDs??

[Art Sepin]

Gentlemen,

What you have is a Motorola SL Oncore navigation receiver, R6 series
model number, with timing firmware installed. These 8 channel receivers,
slightly smaller than the UT+ but larger than the M12x receivers,  were
flashed with UT+ timing firmware and shipped to various telecom
companies between 1999 and 2003. 

Unlike the Motorola VP, GT/GT+ and UT/UT+ receivers, the SL Oncore
receivers are characterized by an RF Dam PC trace in place of the full
metal shield covering the RF components. Most of the SL Oncore receivers
we shipped were mounted in a full, shielded enclosure to operate in
higher EMI environments encountered in telecom installations.

An SL Oncore Engineering Notes document outlines the physical,
electrical and environmental characteristics of this GPS receiver. A
separate User's Guide for the SL was not published. The navigation
firmware load is like the older GT+ and the timing firmware load is like
the UT+. Therefore, the UT+ command/reply messages outlined in the
GT+/UT+ User's Guide can serve as a reference to the timing messages
available in the SL Oncore.

Because of continuing requests, we will be updating our web site to
include information on Motorola's legacy GPS receivers. In the interim,
please let me know where I can e-mail the SL Engineering Notes so that
anyone with interest can make reference to them. Engineering notes in
electronic form are also available for the Basic Oncore, VP Oncore, GT+
 UT+ Oncore and the M12 Oncore (but not M12+) - Thanks!

   Subject: [time-nuts] GPS pcb IDs??
  
   Hi I have just acquired a couple of GPS receiver pcbs, ex Telcoms
  equipment.
   I know a lot of htese poards were discussed so time ago on the
group.
  Does
   anyone recognise what they are and could point me at some
  intrormations
   please.
   I am afraid the flash has washed the the pics out a bit but
hopefully
  there
   is enough detail to be recognised

   The Trimble pcb is 2.6 by 1.25in., and the Synergy is 3.15 by 1.6
in.

Re: [time-nuts] More from the obsolete gps file: oncore nmea

[Art Sepin]

Hi, Folks,

Here are a few things that are intended to correct some statements in this 
thread:

1. There was a mistake in the Motorola GT+/UT+ Users Guide TRM0003 that was 
never corrected. Chapter 6 Table 6.2 lists the Switch to NMEA @@Ci command as 
being included for both the GT+ and the UT+ when, in fact, it is only available 
for the GT+ navigation receiver. I have never seen a UT+ output NMEA messages 
but it was a possibility if the NMEA code was inadvertently switched on at the 
factory. In that case, NMEA would be available but unsupported.

2. It's true that the Motorola designed/produced M12+ Timing receiver did not 
output NMEA messages. But, NMEA messages ARE and HAVE BEEN included in the 
Motorola designed M12M OEM GPS timing receivers produced for our distribution 
since 2006 by iLotus of Singapore (one of SiRF's Value Added Manufacturers). 

3. Synergy Systems, LLC ceased our reflashing service for Motorola Oncore 
receivers on June 22 of 2005; the date Motorola sold its GPS receiver division 
to SiRF Technologies of San Jose, CA.

Since 1999 we have supplied either low-cost or no-cost OEM GPS receivers to 
various, educational endeavors, including Ham Radio, through our GPS for 
Scholars program at this link:
http://www.synergy-gps.com/index.php?option=com_contenttask=viewid=54Itemid=73.
If we don't have appropriate legacy sample boards available at the moment of 
need, we will supply a current model of the needed part at an educational 
discount of 10%. 

In the case of the balloon application, I've determined that we have a GT+ and 
an M12+ navigation receiver in our engineering lab. We are willing to donate 
both parts at no charge to the project - recipient pays for shipping/duty, etc. 
(freight collect). If interested, please respond directly to art @ 
synergy-gps.com with your full name and address details + shipping instructions.

Thanks  Regards,

Art Sepin

Given the interests of the list, I think that you can easily find a member who 
will swap a navigation receiver by your timing GT+. Or you can buy one from 
China in the usual site.  Cheaper than flashing yours at Synergy, I think.
I have a UT+ which fortunately outputs both formats, so I´m served.

 Thanks!! I found that after a while fishing around in the manual. 
 Synergy used to be able to flash the M12+t to an a positioning 
 receiver which does support nmea.

 Bad news is that all of the oncores that I have are of a firmware 
 that doesn't support nmea, either.
 Perusing the manual for the oncores, there is a programming pin. Not 
 sure how it's used or if it can be done outside of a factory. Would 
 be slick to be able to update the firmware!

 Have fun,

 Hi Norm,
  
 not sure if someone discussed this before, but he M12+ and M12M 
 timing  receivers do not support NMEA output, just Motorola binary 
 format.
  
 Motorola disabled this feature on the timing versions of the 
 receivers,  presumably for marketing reasons, or maybe to make 
 firmware regression testing  easier.

 Hi  all!!
 Trying to get a gt+ setup(also tried one of my m12+t's) as a  nmea 
 receiver. @@Ci does not work. Did form the string correctly. Tried 
 it with tac32, used Labview to send the hex string.
 Receiver ignores it and  continues to send moto bin at 9600..
 Any ideas??
 Want to use this for a  balloon flight with aprs. Good news is that 
 we want to launch Friday, so  it's not too pressing.

Re: [time-nuts] Motorola ... ONCORE P/N B8221B116

[Art Sepin]

Ernie,

If you don't have it yet, the complete VP command set is available at
our web site:

http://www.synergy-gps.com/images/stories/pdf/vpcommands.pdf

It's 1.88 mb but hypper-linked and easy to use. The right-most column of
the Command Index called Controller Command refers to a DOS based
software control program that was used with Motorola's Eval Kits of the
early to mid-1990s. 

None of the Motorola navigation receivers included an Auto-Survey mode.
That was only available with the timing firmware so that's why your VP
is not responnding.

Hi Everybody,

Many thanks for all info regarding this module...It is running with
TAC32 software but unable to switch over to self survey mode... the
battery is low,  only +1,4Voltage.

According to my Motorola notes (6/10/98), the unit is a Oncore VP,
version 10.0 firmware, with battery option, differential capability,
right angle OSX connector, and strait 10 pin I/O connector. Does not
look like it has 1 PPS capability or raw satellite data output.

Re: [time-nuts] Motorola ... ONCORE P/N B8221B116

[Art Sepin]

Thanks, Bill.

I'm trying to monitor the group when time permits and help out where I
can. I believe you know that we've hired Cliff Nowak (pronounced Novak)
as our Sr. Engineer. He comes to us from the wireless industry (WaveCom
wireless modules). Cliff took over from Randy Warner who accepted an
offer he couldn't refuse with another company here in San Diego about a
year and a half ago.

For those who do not yet know, we, and the world, lost our friend Randy
back in October to heart attack and stroke at the too early age of 57
years. A notice is available at:
http://www.legacy.com/obituaries/signonsandiego/obituary.aspx?n=randall-
y-warnerpid=136235024

We met Randy back in 1975 when we both worked at Hydro Products, an
oceanographic and offshore products manufacturer here in San Diego.
Synergy hired him in 1997 and he immediately became a hit with our
customers because of his direct approach to solving their problems and
making realistic design/integration suggestions for their products. Many
of his Tech-Notes and Applications Notes for Motorola's legacy GPS
receivers are still requested today. Randy, RIP.

I just received an older 8 channel Oncore GPS board - still not sure if
it is a timing or navigation part...
 In any event, I have found plenty of documentation on it, but so far
none of the links for the Motorola eval software WinOncore (presumably
free) seem to be functional. Can someone help me out?

All I want to do is to be able to easily read the binary output, set
date/time (etc) and change output to NMEA as needed.  I have several
MAX-232 parts so getting good RS-232 isn't going to be an issue.
