3.5.
Connect the control unit to 12V power via a user-supplied cable with a 5.5mm x 2.1mm power
plug.
After the power switch on the EQStarPro is turned on, the unit will sound 1 short, then 3 short and 1
long beep that indicates the EQStarPro is ready.
3.6.
Observe the setting of the control unit using the EQStarPRO setting program on the CD
software.
The settings program can be found in the ‘EQStarPRO settings’ directory on the CD.
Note this program requires the .NET 4.0 framework and VS2013 x86 redistributable to run.
The virtual COM port used by the settings program defaults to COM4, but can be changed in the
settings panel to the one noted above in the Windows Device Manager if it is different.
To see or set the current settings of the EQStarPro, that unit must be started in the settings mode.
With the unit powered off, connect the joystick remote control to the ST4 port of the EQStarPro.
While pressing the ‘Mode’ button on the side of the manual remote control, turn the power on for
the EQStarPro. It should respond with two short beeps to indicate it is in the settings mode.
In the EQStarPro settings panel, click on ‘Load settings’ to see the current settings of the unit.
The EQStarPro kit should come with the EQStarPro correctly set for the mounts supported by this
kit. Of particular importance is the RA and DEC gear ratios. For example, at least the LXD75 and
Vixen GP mounts have 144 tooth worm gears on both axes, so the gear ratio should be set to 576
(144 x 4, where 4 is the step-down ratio from the stepper motor gear to the worm shaft gear).
This program also allows adjusting the GoTo speed, motor current, and acceleration for each axis.
The EQStarPro supports up to x2000 goto speed. Motor current affects the load capacity of the
telescope mount, but also affects how much noise the stepper motors emit.
If the settings do not meet the required settings for your mount, change and save the settings.
