The need for that depends on the specific GPS module used in the receiver. The TrueTime boxes I have seen all have a very clear label on the back of the unit if the down converter is required. If you don't have a label, then you probably don't need the down-converter, and any normal GPS antenna can work. Be careful as some of the systems provide 5 VDC to the antenna, and some provide 12 VDC. If you don't have the OEM antenna (a version of the AT 575) be careful of the DC provided from the receiver so you don't overload any pre-amp you might happen to have. I am not sure who made the down-converter for TrueTime. I have seen these TrueTime systems with standalone down converters, and also down converters integrated into an antenna. Personally I have only used the integrated antenna/converter units and the ones I have are sealed with no obvious manufacturer info... -- Russell ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
[time-nuts] NTS-100 scored
My scrounging luck pulsed this morning, netting me a cheap ($47 with shipping) TrueTime NTS-100 from That Auction Site. It was billed as a 'tech special,' in that the seller claimed it powered up but he was unable to get it to lock to an IRIG signal. Unless I'm mistaken, the NTS-100 is a GPS-based device, yes? I'm off to hunt for its manual, but if anyone has any words of wisdom (or wit) on these units, I'll listen. ;-) Thanks much.

Re: [time-nuts] NTS-100 scored
Bruce, The NTS-100 is almost identical to the 100i, save for the fact that i doesn't have the network management module (serial management only) and DOES produce time code on the serial port. There was a link for the 100i manual on the Symmetricom web site when last I checked, and I found a link to a 100 manual also, but don't have the web site handy. One thing to be careful about, there were several versions of the NTS 100 family, some are GPS based, some actually DO sync to an IRIG signal instead. So you might have a mistaken seller, and you might have one of the less common IRIG units without a GPS. The Part number can usually disambiguate the different versions. -- Russell At 11:52 AM -0700 2010/05/18, Bruce Lane wrote: My scrounging luck pulsed this morning, netting me a cheap ($47 with shipping) TrueTime NTS-100 from That Auction Site.

Re: [time-nuts] NTS-100 scored
In this case, I found out a little more. It actually is an NTS-100i, sub-model NIC-215. I have no idea if this will eventually be good, bad, or indifferent, but the price was right.

Re: [time-nuts] NTS-100 scored
Hi Bruce, I believe the NIC-215 is the IRIG model. The 315 is the native GPS unit. The ones I have seen are all the 3xx series and GPS based. Since you have the 100i you may be able to just go to the Symmetricom web site to download a copy of the manual. They still had it listed when last I checked a few months back. The 100i is almost the same as the 100, but they added an additional module inside to allow network access (telnet and a Web GUI) to the configuration port. You still have serial configuration access, but that also goes through the new module, so they added one or two extra configuration commands (to set the IP for the management module as well as the NTP server IP) and removed the serial time code. I haven't tried it yet, but i suspect the serial time code is still available if you bypass the net management module. I have enough other things that generate serial time code that I never found the time to verify this though. Amusingly the management module has a 100baseT port, while the NTP server still uses 10baseT. It's always interesting to see examples of product evolution like that. I recall reading some posts to the list that were dated a few years back from someone who was experimenting with adding a Trimble OEM GPS rx board to an IRIG version of the 100 (an NTS-100 not a 100i if memory serves). From my recollection I don't think he was successful. I suspect the firmware on the NTS board itself is different between the IRIG and GPS units. In addition, the GPS versions of the 100 series used a number of different GPS modules, most of them that I have seen were Trimble modules. So again I am not sure how easy it is to mix and match sub-modules with these. I've never personally see an IRIG unit, so I am actually rather curious about these :) -- Russell At 1:10 PM -0700 2010/05/18, Bruce Lane wrote: In this case, I found out a little more.

Re: [time-nuts] NTS-100 scored
Not me, no. However, still, no big... It'll be interesting to see what I can do with it once it gets here. Another thing that occurs to me is it may have been field upgraded by a previous owner. I just won't know for a week or two. Thanks much. *** REPLY SEPARATOR *** On 18-May-10 at 22:38 Stan, W1LE wrote: A quick review of the manual shows a GPS antenna downconverter, external device.
