Perhaps they can, perhaps they can't, but why not prove them in their intended configuration before attempting to use a non-standard setup? > I have previously run with the XO & the RB > interconnected (J5 & 10 MHz Ref).

That is correct - no interrogation is necessary. The data comes out gratuitously at 1 second intervals at 9600 8N1 via differential signalling on pins J6-5,9. Note also that J6 1PPS and SMA 15MHz outputs are not present on a unit that assumes a STDBY mode after completing its warmup. 73 de JIM N8ECI _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
