[time-nuts] Synergy-GPS SSR-6tru problems
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] Synergy-GPS SSR-6tru problems
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.

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.

Re: [time-nuts] Synergy-GPS SSR-6tru problems
Yes - To the extent that the 12 channel commands are common to the previous 6 and 8 channel commands. We'll be adding a Tech-Note with this information to the Synergy web site when they are available - perhaps 4Q this year.

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'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.
