Meade Autostar Is Unable to Set Latitude Between 06 and 09 Minutes

Information in this article applies to:
  • TheSky Astronomy Software version 5.00.000 and later


When communicating with the Autostar version 1.3 via its built-in serial port, the Autostar set latitude command (":St DD*MM#") returns an error when attempting to set the latitude when the minutes input is 06, 07, 08 and 09.

To duplicate this behavior, run HyperTerminal (9600, 8, None, 1, No Flow Control) and send a ":St 43*06#" command. The return value from the Autostar is 0, meaning the set latitude command failed.


This is a limitation with the Autostar version 1.3. 



Use the Autostar's hand controller to set the correct latitude or specify your latitude in TheSky to something other than 06, 07, 08 or 09 minutes.
