Re: [time-nuts] Linux code for Prologix GPIB/USB
Hal, no matter whether you use my stuff or not: The very first thing you should do after opening the serial port is to transmit a ++auto 0 to hinder the interface from sending something own its own. My own internal stuff reads as follows: if QCCom32.Opened then begin; Debugform.Console.WriteString('Port has been opened'+#13+#10); Qccom32.Flush; sendstring:='++auto 0'+#13+#10; sendflag:=true; autoenabled:=False; repeat sleep(10); application.ProcessMessages; until sendflag=false; debugform.Console.WriteString('Send ++auto 0 command'+#13+#10); sendstring:='++ver'+#13+#10; sendflag:=true; repeat sleep(10); application.ProcessMessages; until sendflag=false; debugform.Console.WriteString('Send ++ver command'+#13+#10); j:=0; repeat inc(j); sleep(100); until dataavailable or (j=10); if dataavailable then begin; PLfound:=(pos('GPIB-USB',Valuebuffer)0); DataAvailable:=False; end; Best regards Ulrich Bangert -Ursprüngliche Nachricht- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Im Auftrag von Hal Murray Gesendet: Dienstag, 27. Februar 2007 04:32 An: Discussion of precise time and frequency measurement Betreff: Re: [time-nuts] Linux code for Prologix GPIB/USB At the end of the USB cable there is a FTDI chip that (in conjunction with the appropiate driver) emulates a serial port. This serial port in turn is connected to the serial port of an AVR type of microcontroller. Because this microcontroller expects a certain setting of serial transmission parameters you have to set them correct, otherwise it will not understand your commands. Thanks. Makes sense, I guess. I was assuming they had reprogrammed the FTDI chip rather than adding another CPU. (I'm not sure why. The AVR is pretty obvious.) There is a layer of stuff I haven't sorted out yet. It's all tangled up in the GPIB device being at the far end of a serial (USB or RS-232) string. The Prologix defaults to automagiclly reading data when it becomes available and sending it up to the kernel rather than waiting for you to explicitly poll it. I see two cases where that might get confusing. One is when you send it a command at about the time it sends you something. You can't tell if the data you get arrived before or after your command. My normal command sequence is running in single cycle mode so it's easy to stay in lock step once you get started. So far, I haven't had any troubles getting through initialization, but I'll bet my code would screwup if it got delayed for long enough in the right places. The other case is if you are talking to several devices. Again, there is a race as you switch devices. You can't tell if the string arrived before or after you switched. I think this case can be avoided by switching to a device that doesn't exist, checking for input, then switching to the new device. It probably requires some pauses in the right place. I have only very limited Linux experience and even less with Windows emulation under Linux. You probably know more about Linux than I do about Windows. I was just looking for a subroutine package rather than a GUI/IDE. -- These are my opinions, not necessarily my employer's.

As in these: http://www.jrmiller.demon.co.uk/projects/ministd/frqstd.htm http://www.frars.org.uk/cgi-bin/render.pl?parameter=pageid=1285 the loop filter is basically just an RC circuit. It's not quite raw GPS, but is quite different to using a digital filter as used in a Thunderbolt, Shera, etc., which can run to hours. When the N1JEZ board was mentioned, I assumed that it was this type of controller that was meant - and I think it does need 10KHz unless it gets much more of a mod than a couple of counters. Angus. Angus, Don't get me wrong, the James Miller design does a great job, considering it's simple and elegant implementation and the fact that for so little money you can have a frequency standard that beats anything a ham could make in his or her shop. This will do a great job for most applications where you want to be within a few Hz or so around 10 GHz, and as long as the GPS signals are good. For the intended market, if the GPS signals are not good, you simply wait or move the antenna. A lot of the money spent on commercial GPSDO's is spent on improving hold-over performance, because many commercial applications simply cannot postpone using the system until the GPS signal is good. I just wanted to point out that the 10 kHz output can be misleading. The GPS timing is such that if you have a quality OCXO, a loop faster than at least 20 minutes will actually do a disservice to the OCXO, regardless of the PLL reference frequency. If you use an inexpensive, not temperature stabilized VCXO, you can probably speed up the loop quite a bit, simply because the VCXO itself in free running mode will not be doing that great. If your frequency and time needs are modest (and that probably covers 99% of applications, including anything I could dream of personally), this design will be perfectly satisfactory. But, and this is a significant caveat, this is TIME-NUTS where most people are looking at that like the holly grail 1% :-) Didier Hi Didier, Sorry, my original post was not very clear - I had only wondered if faster PPS signals might ever help with the measurement each second; I didn't mean to suggest that they might affect the required overall loop time much. ( Thinking back to all the posts a couple of months ago, I should probably resist any urge to comment on the effect of sawteeth on stability for the moment... ) Anyway, I was just curious. It's one of the many things I don't have much time to mess with, so wondered if anyone else had - but apparently not.

Christophe, Remove the card from the shelf, in front right hand side there is a jumper named DB Init move the the jumper from A to B or vice versa. When the unit starts will detect the change in the jumper and go to factory defaults. Then you can use the default user name and password (is in the manual) NOTE: All settings will reset to default.
