The high resolution stepper motor with MoonLite's Dual Port DRO Display Focus Controller can operate 2
high resolution stepper motors at the same time. Motor port #1 is for our existing high resolution stepper motor
for focusing. Motor Port #2 is for our soon to be released rotating flange system. This new controller will be able
to provide a complete 2 axis automated setup. The controller operates just like the Mini controller above, but has a
display to show position. It also comes with a remote temp probe.
Connection
MoonLite provides a 6 foot 9 pin DBA serial cable to
go from the controller to the high resolution stepper
motor on the focuser. The cable looks like a serial
cable; however, the signals from the controller to the
motor windings are not computer signals. We use the
first 5 pins in the cable to power the stepper motors
windings. Extra long (20') serial cables are available
if needed. Two cables are included with the dual port
DRO display controller for future use with the flange
rotator option.
A universal AC adapter is included with all controllers
that will operate in different countries' power (install
the matching plug style in the 12 volt AC adapter you
require). We include a 6 foot USB cable with the new
controller. Some customers use a USB hub for long
distance runs. A remote temp probe can be plugged
into the controller to bypass the built in temp probe located inside the case. Once plugged in, it will defeat the internal
temp sensor. The probe can be taped to the side of the telescope for better thermal reading of the OTA.
Basic Operation for the Dual port DRO display controller
First connect all cables and power up the controller using the power switch on the left side
Please note the boot sequence:
•
The Display will go from Red, Green ,and Blue.
•
Then display "MoonLite Telescope" and the version of the software "Ver 20".
•
It will then give a message "Press a button to enter menu". Do not press any keys during that time, so the
controller can go in to normal operation. If you press a button at that time it will go into advanced menu mode.
To get out of advanced menu mode – just cycle the power off and back on.
Top line of display shows step count position for focus motor on port #1
Bottom line of display shows step count position for rotator motor on port #2
Right side of display will show the temp detected by either the internal or remote external
temp probe.
Red buttons will increase / decrease the focuser's position (rack in / rack out).
Blue buttons will rotate the focuser, either right or left.
The focus steps are fine and slow when the button is first pressed , but will go faster if the
button is held down. Please remember to rack the focuser the whole way in to zero the
step count to the focusers fully racked in position (hold the button down until the focuser
is fully racked in. No harm will come to the focuser, as it will simply slip when hitting the
mechanical stops).
