Re: [time-nuts] TU60-D120-041 power up
Hello Michael, Re: setting GPS data formats As I mentioned previously, my GPS unit works perfectly with the TAC32 evaluation software. I can see the NMEA sentences on the screen every second. In addition, the 1 pulse-per-second is working, and so is the 10 kHz output. So, I have a working GPS system. I can proceed from there to build up the 10 MHz Oven Stabilized Oscillator and complete the GPS Disciplined Oscillator. I think you pointed out that this GPS unit defaults to the Navman Binary mode. I have tried to use HyperTerminal via a serial port and about all I see is @@EA followed by a burst of random characters every second. I tried 4800 and 9600 baud. I would like to be able to read the NMEA sentences (GPGSA, etc) so I can use Day, Date, Time and 3D Fix for other purposes. To do that I think I need to change the format of the GPS output data. (From Navman Binary to ) I am still uncertain about how to send commands to my TU60-D120-041 GPS unit. I have spent hours trying to understand serial communication with GPS units and I haven't had much luck. You mentioned that you developed some software that would accomplish that. Any help would be greatly appreciated.

For things like this, my first try is usually gpsmon from the gpsd package. It's very good at figuring out what type of device you have. By default, gpsmon /dev/ttyXXX (for whatever the filename is on your setup) will try various baud rates and such until it recognizes something. Then it decodes and displays the data. By default it doesn't change the speed or mode. There is a command to switch to/from NMEA and binary modes, and a command to change the baud rate. There is another command to try harder to discover the device type. That sends commands that might confuse/break some devices. Switching to NMEA mode may get lost when you reset or power cycle the device. It will probably stick around long enough for you to debug the next layer of software. You can probably find the command to switch-to-NMEA in the gpsd sources. -- These are my opinions.

Re: [time-nuts] TU60-D120-041 power up
I wonder if these are similar to the TU30 series. On those, grounding Pin 7 on J1 would bring the unit up @ 4800 baud NMEA...

Re: [time-nuts] TU60-D120-041 power up
Hello Michael, I apologize for the long delay to your reply. I have spent a lot of time upgrading my computers from Windows XP to Windows 7 and I ended up losing a lot of information - my fault. I have been using the TAC32 demonstration software and I have been able to verify that my GPS unit is working fine. I would eventually like to build my GPS into a 10 MHz disciplined oscillator. Since I know my GPS is working OK I would appreciate hearing about the program you mention in your reply. I have limited software experience but I would like to try it on my system. Will you please send me your program with some basic instructions? Thank you for your kind offer to help.

Hi Michael, Thank you for your suggestion. This is my first post to the group so I hope I am replying correctly. I have downloaded WinLabMon (for Windows XP?) and WinOncore12 but I have not been able to communicate with the GPS receiver yet. Yes, please send me the program you mentioned and I will try it out. Please email to the address shown on my message.

Re: [time-nuts] TU60-D120-041 power up
Hi Jerry PM sent. I developed some years ago a GPSDO using the TU series GPS receivers, you can see the product on this link under the GPS: http://rudius.net/oz2m/ngnb/index.htm Regarding the TU-60 you need to convert from the Motorola format to Navmann format first and then from Navmann format to NMEA format, then you can read all the information on your sw programs. I use the program realterm to do this. When you turn off power it will not remember the NMEA setting not even with a backup battery and you need to do the procedure again, the TU-30 modules remember the settings.

[time-nuts] TU60-D120-041 power up
I bought a receiver labelled as Conexant Jupiter-T TU60-D120-041. I constructed an RS-232 serial interface, a 1 Pulse per Second LED and a 10 kHz test point. After a few minutes the 1 pulse per second LED syncs up with the audible ticks on WWV so it seems that the receiver is receiving the satellites in some fashion. I would like to monitor the satellite and receiver status using WinLabMon or something like it. At power up I see a single 14 msec burst of data coming out of the receiver serial port but I have no idea what that data says. Is that the default power up state, just a single burst of data? What should I be doing to get meaningful data out of the receiver into the computer?

Re: [time-nuts] TU60-D120-041 power up
Jerry it transmit navmann binary protecol and the 1 Sec puls come on almost after power on but it produce this pulse both with or without sattlites received, I can mail you a small program which program it to transmit NMEA format, it does not keep this infor when powered off.
