All telescope commands are prefaced by 't' and must be lower case. The MOVE commands themselves are not case-sensitve. They are all mapped to uppercase before processing.
These commands are generally passed directly to the MOVE computer without any special processing. Most commands are two characters followed by zero, one or two arguments. Arguments are restricted to integer values only except for the ON command. The arguments for three special commands (CO, ER, and RM) are processed by the daemon to convert them from a user friendly format to that required by MOVE. Commands in italics are used in the queue but are usually reserved for use in special maintenance file command sequences.
Note: The telescope cannot go North of +64:17 declination. This is not safe at all hour angles but is only a problem for hour angles > 6 hours. +61 is pretty much safe everywhere. At -47:30 on the meridian, the telescope is just seeing the bottom edge of the dome slit.
|ALTAZ X X||Move to altitude,azimuth|
|CO X Y||Move to ra,dec - equinox 2000.0|
|DJ X||Dome jog: move dome by X degrees|
|DM X||Enable automatic dome|
|DS X||Deadman switch, activate in X seconds|
|EE file||Ephemeris enter (file is name of file)|
|EG X||Ephemeris go to object X|
|ER X X||Enter rates, in s/hr, "/hr|
|FG X||Change focus to absolute position|
|FR X||Change focus by relative amount|
|FT X||Focus type (0=Absolute, 1=Relative) ???|
|HO||Move to home position|
|LI X||Toggle light|
|LM X||Set lock mode|
|LP||Move to last saved position|
|LS X||Toggle light supression flag|
|ON X||Move to named Object|
|RF X||Read from file and go to it|
|RM E N||Relative move, in arcsec (East, North positive)|
|SF X||Read sky from file and go|
|ST||Set MOVE clock, no change in pointing.|
|TC X||Track on/off|
|UI||Move to twilight flat sky position|
An X indicate a required argument. For all that are logical values, on is 1 and off is 0. Again, except where noted previously, all arguments are strictly integer numbers. CO can accept a pair of "free-form" coordinates, equinox 2000 only. RM takes two numbers in arc-seconds (decimal ok). ER takes two numbers in arc-sec/hour (decimal ok).
Most commands return their responses pretty quickly. There's a 1 second timeout on most of these. The exceptions are: ER (0.5 seconds), HO (30 seconds), OS (210 seconds), RM (5 seconds), UI (30 seconds).
