12V-13.8V DC unregulated
4 Amps max (each)
2.1mm DC Power Jack / Center Positive
DUAL PORT USB2 HUB
Prodigy Microfocuser includes an industrial grade USB hub IC capable to deliver 2 x USB2 High Speed
ports. These dual stacked ports exist on the side of the Prodigy. Both USB ports are controllable and can
be switched ON/OFF via supplied software.
These USB ports allow the connectivity of equipment close to the Prodigy focuser such as a Filter Wheel,
a guiding camera, a motorized OAG etc.
MOTOR OPERATION
Prodigy Microfocuser has an embedded stepper motor. Its rotation is driven via a belt and pulley system
to the focuser’s
drawtube. Stepper motor design ensures a smooth, low noise and
backlash
free
operation. V-Curve points during automatic focus procedure are dead accurate.
•
Focuser has been (factory) configured to perform position steps from 0 -> 11000
•
Each step movement is 0,0227 mm / 2.27 micron
RESET WATCHDOG
A hardware watchdog resets the device if for any reason there is no response from the controller after
two (2) seconds. A neat feature in the unlikely event of a microcontroller freeze
–
when have a remote
observatory and you need to be sure that everything works as expected.
OPERATION LED
A red colored LED is fitted on the centre of the Prodigy enclosure. Every time the motor is moving the
LED lights on to indicate that Focuser is sliding in or out. When motor is idle, led turns off to avoid any
light reflection inside the focuser.
RECOMMENDATION
•
It is advised to select and use good quality and short length USB cables.
•
Do the same for power cables. Long and thin power cables will have an effect of voltage drops.
This can cause issues to your camera (CCD or CMOS) image quality or mount tracking.
