[time-nuts] RFTGm-II-Rb - can you gps discipline it without the XO module?

[Alan Kamrowski II]

Hi Everyone,

 

I've only got the RFTGm-II-Rb module.  I found an interface cable
specification here:

Does anyone know if feeding a 1pps signal to pin 9 might discipline it?  Or
does it need the other connections such as GPS data, etc.

 

Is there a ground on this connector?

 

Thanks!
