Re: [time-nuts] Control and monitor program for Spectracom 8195B
Yes, I noticed there was an instructions on setting the range of OCXO's high and low, so it falls within "correctable" range of the PLL. I bet many GPSDO has something like this - just not explained so explicitly in manuals. Can we try sending the .exe again? I think if you zip up the below picture and .exe together, it should work.

The problem with the 8195 is that the serial port software interface was designed for human interaction with very little regard paid to supporting a computer monitoring program. ___ time-nuts mailing list -- time-nuts@lists.febo.com To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.

Hi My solution is to kidnap Mark’s pet goldfish and hold it captive until the specific device is incorporated into LH …. :). In the case of expensive or rare gear lending out a device might get things going faster than the goldfish maneuver ….

[time-nuts] Control and monitor program for Spectracom 8195B
I recently acquired a pair of Spectracom 8195B GPS Ageless Master Oscillators. Using terminal emulation on PC and RS232, I can configure and monitor their operations. They are working fine. But, I cannot seem to be able to find any Windows based software to configure OR monitor operations. It does not seem any publically available software supports this GPSDO. My go-to package, Lady Heather does not support it. Does anyone know a source of one? I have so many GPSDOs now that I cannot possibly remember command for each. (or remember which one takes which command) --- (Mr.) Taka Kamiya KB4EMF / ex JF2DKG ___ time-nuts mailing list -- time-nuts@lists.febo.com To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
