dropleaf [open] [close] [time=] | [limits]
WARNING The dropleaf must be opened and closed only when the main shutter is fully open it will overlap. The slit must open before the dropleaf can be opened. The dropleaf must close before the slit can close. There is NO software checking for this condition.
The open option turns on the motor for approximately 25 seconds and opens the dropleaf shutter. The program delays while the motion is in progress. The close option turns it on in the opposite direction for 27 seconds, hanging till done. There is NO readback whether the dropleaf is either open or closed. This is a serious deficiency of the hardware design.
The time= sets the motor times manually for that invocation only.
Opening during inclement weather is prohibited by sofware see slit command below for details.
Returns the values of the Vaisala weather station and the precipitation sensor.
Example: tx mets done mets windir=285 windspeed=8.0 peak=8.5 oat=6.3 humidity=85.8 pressure=806.8 rainintensity=0.0 rain=0
slit [stop] [open] [close] | [limits]
This command commands the observatory main shutter.
reports back something like:
Example: done slit busy done slit cantopen=sun,windy done slit manual estop cantopen=sun,rainUnfortunately, the software is unable to report back the current state of the slit.
To open the slit enter:
tx slit open
At which time the slit will begin to open and report back immediately
tx slit busy
The slit motion will continue for about ?? seconds reporting
busy if still in motion.
You can use the command
tx slit stop
to stop the motion of the slit, the red STOP button on the
manual paddle also can stop the motion (even in Auto Mode).
The software checks for inclement weather and prohibits opening
when these are violated; closing is allowed in all conditions.
cantopen keyword is only present when the slit
cannot open. Possible reasons that it cannot open are:
done slit sunalt=10.0 humidity=90 windspeed=14 rain=1
Error messages will be issued if the dome open request is made and the weather is bad.
tauxtaux reads the auxiliary temperature sensors and in particular the cloud sensor. The command returns a string similar to
done taux ovolts=6.309 irvolts=1.919 cloud=0.01 dew=3.01where: ovolts - the temperature sensor reading of the cloud detector irvolts - the infrared sensor reading of the cloud detector cvolts - the temperature sensor reading of the drive cabinet cloud - 0 to 1.0 reading where 0 is clear and 1 overcast dew - the analog output of the rain sensor 3 volts is dry lower is wetter The cloud conversion is very approximate.
