GSS6300, SimCHAN: Why do I get error message 'Reference frequency not locked, GSS6300 serial # 6xxx'
Environment/Versions
SimCHAN
GSS6300
GSS6300M
GSS6300Mi
Dual box configuration
External reference connected
Answer
There are 2 main causes of this error message
There is no cable connected between the Master and Aux 'expansion port'
An external frequency has been supplied to both the Master and the Aux unit.
The correct setup is:
External frequency, if used, connect to 'EXT REF IN' of the
Master unit ONLY
Cable connected between Master and Aux 'Expansion port'
DO NOT CONNECT EXTERNAL REFERENCE TO BOTH UNITS!
