Ryan, If the card is a GPS PCI 2 then you can get the user manual and a data sheet from This is Symmetricom's new web site for Timing Test and Measurement and it has most of the documentation for Symm, Datum and TrueTime products. Telco products are still on the main Symmetricom site. Nelson, Ryan Lorne wrote: >Hi, >>I was wondering if anyone had ever set up a TrueTime GPS-PC card for Linux.

Hi, I was wondering if anyone had ever set up a TrueTime GPS-PC card for Linux. I haven't been able to find much documentation on how to get this ca.
Hey, No, the card I have is the ISA version (I have the manual for it, but i have been unable to figure out a way for Linux to be able to use it. The only information I found on it was at but I am unable to figure out where to get the driver that it mentions here. Any help would be greatly appreciated.

At a minimum, try putting the lines: server 127.127.5.0 prefer fudge 127.127.5.0. In your ntp.conf You'll have to dig into the documentation for anything else you might need. Or you could find someone who knows and ask him!

Thanks, Ryan Nelson _______________________________________________ questions mailing list questions@ntp.org --------------0307. I have been looking at this issue also. This is what I think is correct. I would appreciate a correction from anyone who can point to appropriate documentation that more clearly answers the question posed. Unfortunately, I believe that the 'drivers' in the ntp distribution are drivers that load into the application itself. The TrueTime driver appears to presume that the true time 'GPS' receiver is one with a serial line output. The linux kernel already has drivers that operate the serial line and feed the bytes to the application so that the ntpd application driver merely needs to parse the byte string into an appropriate time stamp.
In the case of an ISA or PCI card, I presume that a Linux kernel driver is needed as well. This would allow the 'application level driver' in ntpd to 'open' a special character device and obtain the timestamp as bytes (probably binary) read directly via the I/O bus, no through a serial port.

John, As you might know, TrueTime was devoured by Symmetricom, although it seems they will continue to market the NTS-200 at least.
TrueTime used to make (and maybe Symmetricom still does) a GPS receiver with serial output (type 5). What you may have is the TrueTime TT560 GPS/IRIG PCI card, which uses a different driver (type 41). I have not tested any of these. Dave John DeDourek wrote: >>I have been looking at this issue also.
