PyxisControl is an astronomy utility which can control Optec's Pyxis 2" and 3" Field Rotators. Additionally it can link to Software Bisque's TheSkyX Pro to control the orientation (Position Angle) of a selected Field of View Indicator (FOVI). These will be synchronized when both are connected to PyxisControl. A measured camera angle can also be entered and this will result in automatic offsetting of the Pyxis rotation angle to compensate.
• rotation controlled by clicking a graphic dial;
• rotation can also be nudged by selectable amounts;
• rotation can be commanded to an exact angle;
• PyxisControl uses recent updates to the command protocol to enable fractional angles;
• PyxisControl remains backwards compatible with all previous versions of the Pyxis firmware;
• rotation direction can be specified as clockwise or counter-clockwise to account for arbitrary reflections in the optical path;
• general Pyxis commands can be sent: Home, Sleep, Wake and Restore;
• advanced configuration of the Pyxis can be performed.
PyxisControl offers Mac-based astronomers the opportunity to use all the capabilities of the Optec Pyxis serial-controlled rotators.
Note that a USB-Serial converter is needed to use this application for Pyxis control. The USB-controlled Pyxis LE is not supported.
PyxisControl requires MacOS X 10.6.6 and has the following requirements for use with Pyxis:
• Pyxis 2" or Pyxis 3"
• USB-Serial converter
For use with TheSkyX Pro the following requirements are valid:
• TheSkyX Pro 10.1.10
• or, 10.1.9 Build 4276
A USB-Serial converter is needed before the Pyxis can be connected. These devices are available from many vendors, but largely fall into 3 groups:
• devices manufactured by Keyspan (now TrippLite-Keyspan);
• devices based on the FTDI chipset;
• devices based on Prolific chips.
The Keyspan devices are known to work with this application, but the driver for MacOS X 10.7 (Lion) is still in a beta stage.
The FTDI-based devices (many vendors) are also known to work, have a good reputation and the drivers are frequently updated for MacOS X.
Devices based on the Prolific chipset sometimes present problems on MacOS X. None have been tested with this application.
