[time-nuts] Z38xx and z3805

[Bob Camp]

Hi

The boxes all seem to go into survey, complete it and then happily lock up.
One seems to have a broken "lock" LED, but z38xx shows it running fine. 

If I understand you correctly, there is no real "write to eeprom" command.
It's just a matter of turning off the survey at boot function.

I'll have to poke at the beasts tonight and see what they says about their
current survey settings. 

Thanks!

Bob

Hi Bob,
   I have a Z3801A and I am not sure whether the SCIP commands are the 
same as for the Z3805A. There must be some differences related to the 
channel numbers and serial post configuration at least I would expect. I 
think the following apply.

   You need to not only be able to provide a position, as was suggested, 
or from a survey, but to also prevent site survey from starting up at 
power on. Survey at start is default, at least on the Z3801A, and from 
what you say, I suspect your box does the same.
If a position is specified, or the survey completes OK, the unit should 
go to position hold mode automatically.
  To check.
:GPS:POSition:HOLD:STATe?

To specify what startup mode you want
:GPS:POSition:SURVey:STATe:POWerup ON or OFF    ON forces a survey.
  to check
:GPS:POSition:SURVey:STATe:POWerup?

If it is turned off the receiver will use the last valid position it 
has. This might be the default , (Korea) if the eprom is shot.

hope that helps,
Mike
