REFERENCE INFORMATION
85
ORigin
Set the origin for motor position to be angular units clockwise from the reference
sensor. Returns OR. On all subsequent POsition commands, positions are given relative to this
user-defined origin. This command is only permitted after protection has been removed with the
PWord command.
PWord
Allow modification to configuration data. Returns PW if it succeeds and PW if it fails.
Modification remains possible until 5 consecutive minutes elapse without communication. The
parameter must match the four-digit number stored.
PWord
Disallow modification to configuration data. Returns PW.
PWord
Sets the password. Returns PW if it succeeds and PW if it fails. The parameter must
match the four-digit number stored. The parameter must be a four-digit number to replace it.
Modification must be enabled prior to entering this command.
SC
Retrieves the scaling factor for each sun sensor quadrant along with the nominal scaling of the
sensor. The scaling factor is used to convert the voltage from a given quadrant to the intensity that
is needed to create that voltage from that quadrant. The scaling of the sensor indicates the number
of degrees of error required to translate from "centred on the sun" to "no longer able to measure".
Returns SC .
is the multiplier for the quadrant collecting light from the region counter-clockwise in
both azimuth and zenith.
SC
Sets the scaling for the sun sensor. Returns SC. This command is only permitted after protection
has been removed with the PWord command.
SErial
Retrieves the instrument serial number from permanent memory. Returns SE .
SS
Retrieves the amount of time over which each sun observation takes place and the intensity level
below which the sun is deemed to be obscured. The sun must not be obscured at any time during
an observing period for an observation to be logged. Returns SP .
is in seconds. is in W/m².
SS
Sets the sun sensing parameters. This command is only permitted after protection has been
removed with the PWord command.
STeps
Retrieves from permanent memory the number of stepping units in a complete revolution for all
motors. Returns ST .
STeps
Set the number of stepping units in a complete revolution into permanent memory. Returns ST. The
number of stepping units depends on the setting for the motor controller. This command is only
permitted after protection has been removed with the PWord command.
