Re: [time-nuts] Synergy-GPS SSR-6tru problems
Hi Paul, No, it's the right configuration. The part number is as you say and it says SSR-6tru on a paper label. I'm certain it's something on my end, but I just don't see it. I think I'm going to go the mini-clips route, assuming a USB adapter will power the board. I'll have to look at the specs to see current draw.

Re: [time-nuts] Synergy-GPS SSR-6tru problems
Dennis, I fooled around with PUBX 41, and can't get the board to respond. I think that with the original board, I *once* got some PUBX messages, but at this point I am only seeing NMEA broadcasts. That once may have been when I was using a serial port instead of the USB I'm using right now. This evening I will get in with the scope and do come comparisons on the 10-pin connector to see if there are differences between then the UT+ is plugged in and the SSR-6tru mounted on the adapter card. I have an ftdi adapter that I may put on as well if nothing else gives any results. I don't have the ability to deal with those .05" spaced pins on the GPS board's connector, or to supply the 3V power. But, if needs be, I can get a connector, put in a 3V regulator, and give that a try. Come to think of it: one of my little USB to TTL adapter boards can supply 3V. Maybe I can use some mini-clips to jumper directly to the .05" pins on the GPS board, let the USB adapter supply the 3V, and give that a try. I'm a bit leery of going that route, though. If I get pins mixed up and blow the board I've wasted all this time for nothing.

I've got several of these boards and they've worked okay for me without doing anything special. I have not tried the software you are using, however, nor do I use the adapter you mention (does that adapt the connector on the SSR-6tru to a connector that fits your UT+ board?). I made a connector to talk to mine directly from a 3 volt serial port in a BBB SOIC. Since you can see the NMEA sentences the transmit side of the serial port from the LEA-6T is clearly working and you have the baud rate right, but your symptoms suggest the module doesn't hear you. Have you tried looking at the basic connection, i.e. that the serial port receive pin on the module wiggles at the right voltage and polarity when the software tries to send stuff (maybe there are two ways to plug in the adapter, only one of which works)? If that looks okay then the only other guess I can think of is that the software is trying to talk to the board with u-Blox binary messages but that protocol has been turned off for input on the port (the PUBX,41 NMEA sentence can turn it on and off), but that seems unlikely since, no matter how I reconfigure mine, a power-on reset always sees the serial port come up willing to receive either protocol.

Re: [time-nuts] Synergy-GPS SSR-6tru problems
Hi Rex, Arts reply wasn't relevant because the board talks ublox rather than Motorola binary. The board has the same footprint as the UT+. You just plug it in. They sell 2 versions: one that talks ublox and one that talks Motorola binary. I got the ublox version so that I'd get some experience with that with the new GPSDO that I'm building. However, my GPSDO is not yet hooked up to the comms on the receiver. The comms is going directly to a PC. When the UT+ is in, I have no trouble controlling it with WinOncore12. When the SSR-6tru (which is an LEA-6T on an adapter board) is plugged in, I should be able to control it with ublox's "u-center" program. For whatever reason, I can't. They, Synergy, have tested this board on their test platform, using u-center software. It works. I have absolutely no doubt that it works. I've seen screen shots. I just don't understand why it's not working here. There has to be something, probably something quite trivial, that I'm missing. My comms signal is getting onto the board. I can see it with a scope. But, in spite of that, something is still not right.

Re: [time-nuts] Synergy-GPS SSR-6tru problems
Art, I don't see that your response is relevant. This board uses the ublox command set. I mentioned the UT+ only in context of the hardware. It plugs into the same socket on my GPSDO. When the UT+ is in, I can control it with WinOncore 12 software with no problems. When the SSR-6tru is plugged in, I am trying to use ublox u-center 8.11 software to control it. It is deaf to all commands, and I do not see a reason. I have an expired version of your SynTac program and it complains of comms errors, though it then happily displays the satellite signal strength; probably from the NMEA broadcasts. I have brought up your SynTac software in a new Windows XP virtual box so that it is not expired. It is not able to control the SSR-6tru. I do not know what the problem is. The UT+ works (with the appropriate software). The SSR-6tru is deaf using all the software I have available to me. I am at my wits end, and I have nothing else that I can think of to try. I did not open this thread to start an argument with Synergy-GPS. I was hoping to get input from someone else who had installed this board with the adapter board and had it working or even who had experienced problems.
