Well Bob There you go changing the game just a bit. I saw the NTP settings and was thinking for some reason it might want to access a NTP server. I can see I have it backwards. Just may add a IP. I would have gotten there given time. But I will take a short cut any day. The Net RS is reasonably low

Hi More NetRS trivia: One of the features of the NetRS is that it will act as an NTP server. It’s not the most modern device so I very much would not want to serve a ton of clients off of one. It also has been a *long* time since the OS was patched. If you are looking for “modern” features or

You can stream data out of the receiver via either TCP or serial port without storing to disk, so that's probably the best bet to save CF wear and tear. I'm not sure if it's more difficult to turn the But for now I'm doing as you suggest -- I have one "T00" format session logging to disk in 2

Hi The simple answer is to not log the data to the card at all. Just grab it “real time” via the serial port or the ethernet port. Both ports can be set up to “send when ready” so there is no need to do a bunch of polling to grab the information. Since you have multiple serial connectors and t

Hello Time-Nuts, Seems like there has been a lot of interest in the NetRS lately because of their availability at reasonable prices (sometimes). They use a Compact Flash card to store the operating system and logged data files. I'm not very knowledgeable about Linux, but I would guess that there

Hi Tobias, I'm very new to all this GPSDO stuff and going through similar learning but maybe I have some remarks/questions that could be relevant for you. - Developing control algorithms is an extremely long process unless done on a simulator. Tom Van Baak has an excellent simulator and several
