Command :Sg DDD*MM#
Returns Ok
Sets the longitude of the currently selected site.
Command :GG#
Returns sHH#
Gets the offset from Greenwich Mean Time.
Command :SG sHH#
Returns Ok
Sets the offset from Greenwich Mean Time.
Command :W1#
:W2#
:W3#
:W4#
Returns Nothing

c. Telescope Motion
Command :Mn#
:Ms#
:Me#
:Mw#
Returns Nothing
Starts motion in the specified direction at the current rate.
Command :MS#
Returns 0, 1, 2, or 4 (see description)
Slews telescope to current object coordinates.
returned if the telescope can complete the slew, 1 is
returned if the object is below the horizon, 2 is returned if
the object is below the "higher" limit, and 4 is returned if
the object is above the lower limit. If 1, 2, or 4 is returned,
a string containing an appropriate message is also
returned.
Command :MA#
Returns 0
Slews telescope to object alt-az coordinates (set with the
Sa and Sz commands). This command only works in the
LAND and ALTAZ modes.
Command :Qn#
:Qs#
:Qe#
:Qw#
Returns Nothing
Stops motion in the specified direction. Also stops the
telescope if a slew to an object is in progress.
Command :Q#
Returns Nothing
Stops a slew to an object.
Command :RG#
:RC#
:RM#
:RS#
Returns Nothing
Sets the motion rate to guide (RG), center (RC), find (RM),
or slew (RS).
Command :Sw N#
Returns Ok
Sets the maximum slew rate to "N" degrees per second
where N is 2 through 4.
d. Home Position
Command :hS#
Returns Nothing
Starts a home position search and saves the telescope
position. NOTE: All commands except ":Q#" and ":h?#"
are disabled during the search.
Command :hF#
Returns Nothing
Starts a home position search and sets the telescope
position according to the saved values. NOTE: All
- 56 -
commands except ":Q#" and ":h?#" are disabled during
the search.
Command :hP#
Returns Nothing
Slews the telescope to the home position.
Command :h?#
Returns 0, 1, or 2
Returns the home status: 0 if home search failed or not
yet attempted, 1 if home position found, or 2 if a home
search is in progress.
e. Library/Objects
Command :Gr#
Returns HH:MM.T#
Gets object right ascension.
Command :Sr HH:MM.T#
Returns Ok
Sets object right ascension.
Command :Gd#
Returns sDD*MM#
Gets object declination.
Command :Sd sDD*MM#
Returns Ok
Sets object declination.
0 is
Command :Sa sDD*MM#
Returns Ok
Sets object altitude (for MA command).
Command :Sz DDD*MM#
Returns Ok
Sets object azimuth (for MA command).
Command :CM#
Returns (see description)
Sync. Matches current telescope coordinates to the
object coordinates and sends a string indicating which
object's coordinates were used.
Command :Gy#
Returns GPDCO#
Gets the "type" string for the FIND operation. A capital
letter means that the corresponding type is selected while
a lower case letter indicates it is not.
Command :Sy GPDCO#
Returns Ok
Sets the "type" string for the FIND operation.
Command :Gq#
Returns SU#, EX#, VG#, GD#, FR#, PR#, or VP#
Gets the current minimum quality for the FIND operation.
Command :Sq#
Returns Nothing
Steps to the next minimum quality for the FIND operation.
Command :Gh#
Returns DD*#
Gets the current "higher" limit.\
Command :Sh DD#
Returns Ok
Sets the current "higher" limit.
Command :Go#
Returns DD*#
Gets the current "lower" limit.
Command :So DD*#
Returns Ok
Sets the current "lower" limit.
Command :Gb#
:Gf#
Returns sMM.M#
