If the LX200 does not respond to the N, S, E, or W keys, be Range 00* - 90* "Higher" parameter (degrees). sure the CAPSLOCK is OFF. If it still does not work, check the PC serial port pinouts of your computer to be sure they are TT.T Example 59.2 wired correctly to the LX200 6-line connector. Range 56.4 - 60.1 With a successful check-out of the PC link with the LX200 using Tracking "frequency." LX200 TEST, you are now ready to write your own software program using the LX200 Command Set, or to use the sample program called "DEMO" that is written in Quick Basic software language. info Example CNGC1976 SU DNEBMAG 3.9 SZ 66.0' Range n/a Object information. 3. LX200 Command Set Intended for professional programmers, the LX200 Command Set is used to write custom software for remote operation of the telescope with a PC. Each command is listed in a section appropriate to its type. Each entry in the command list includes the command name, any parameters, any return values, and a description. The parameters and the return data are shown in a manner that indicates their format. These formats are listed below along with examples of how the data might actually appear, the legal range of values, and a short description. Below is a detailed description: a. Command Set Formats HH:MM.T Example 05:47.4 Range 00:00.0 - 23:59.9 Hours, minutes, and tenths of minutes. Ok Example 1 Range 0 or 1 Status value returned after setting values. If the value is legal 1 is returned, otherwise 0 is returned. b. General Telescope Information Command :GR# Returns +HH:MM.T# Gets the current Right Ascension. Command :GD# Returns sDD*MM# Gets the current Declination. Command :GA# Returns sDD*MM# Gets the current Altitude. sDD*MM Example +45*59 Range -90*00 - +90*00 Signed degrees and minutes (the '*' represents ASCII 223 which appears on the handbox as a degree symbol). DDD*MM Example 254*09 Range 000*00 - 359*59 Unsigned degrees and minutes. HH:MM:SS Example 13:15:36 Range 00:00:00 - 23:59:59 Hours, minutes, and seconds. MM/DD/YY Example 02/06/92 Range 01/01/00 - 12/31/99 (see description) Month, day, and year. The two digit year indicates the following: 92-99 = 1992-1999 00-91 = 2000-2091 sHH Example -5 Range -24 - +24 Signed hour offset. NNNN Example 3456 Range 0000 - 9999 Four digit object number. Command :GZ# Returns DDD*MM# Gets the current Azimuth. Command :GS# Returns HH:MM:SS# Gets the current sidereal time. Command :SS HH:MM:SS# Returns Ok Sets the sidereal time. Command :GL# :Ga# Returns HH:MM:SS# Gets the local time either in 24 hour (GL) or 12 hour (Ga) format. Command :SL HH:MM:SS# Returns Ok Sets the local time. NOTE: The parameter should always be in 24 hour format. Command :GC# Returns MM/DD/YY# Gets the calendar date. Command :SC MM/DD/YY# Returns Ok (see description) Sets the calendar date. NOTE: After the Ok, if the date is valid, two strings will be sent. The first will contain the message "Updating planetary data," the second (sent after the planetary calculations) will contain only blanks. Both strings will be terminated by the "#" symbol. sMM.M Example 02.4 Range 05.5 - 20.0 Signed magnitude value. NNN Example 134 Range 000 - 200 Three digit object size (minutes). Command :Gt# Returns sDD*MM# Gets the latitude of the currently selected site. Command :St sDD*MM# Returns Ok Sets the latitude of the currently selected site. Command :Gg# Returns DDD*MM# Gets the longitude of the currently selected site.
