[time-nuts] Upgrading TS2100 from TCXO to OCXO

[Greg Dowd]

I think a couple of those bits do correspond to the oscillator type installed but I think you can ignore them.  If I remember right, those oscillator bits were only used to calculate the dispersion update for ntp packets when flywheeling through a loss of signal. As far as I recall, you just need to change gain and filter.  And the setting for the current d/a value should have been accessible in root tim utils as d2a.

As someone pointed out, the default ovenized for those boxes was the MTI 240 low profile.

If anybody has a TS2100 that came from the factory with an OCXO, can you
telnet into the unit and run the following command?

root eng ee info

This appears to be some sort of factory-configured personality of the
board.  My TS2100-GPS unit with a TCXO has an info value of 00000024.  A
TS2100-IRIG unit (no GPS) with a TCXO has a value of 00000000.  I'm
curious whether any of those bits correspond to the oscillator type or
if all that needs to be changed is the gain. 

Thanks,
-Bob
