PrimaLuceLab iSrl ESATTO user manual
Controlling ESATTO with EAGLE or computer with Windows OS
ESATTO can be controlled with the EAGLE or any external computer running Windows operating system (64 bit, version 7
minimum). In the ESATTO package you will find a 12V power cable with cigarette plug style connector, and a USB cable for
connection to a PC. If you have a PC with a USB 3.0 port that supplies at least 1A of current (please refer to your PC speci-
fications) you can control and power ESATTO only with the supplied USB-C cable, otherwise you must use the 12V power
cable with cigarette plug (or an optional 12V AC adapter with Ø5.5 ø2.5mm jack capable of at least 1A).
Connect the USB-C cable to the USB port of your EAGLE or per-
sonal computer. You will see the PWR LED on (this means
ESATTO is powered) and, after a few seconds the Wi-Fi LED will
also be become lit - This means that the ESATTO is online and
the WiFi connection is ready to be used.
Once connected the ESATTO should be automatically detected
and Windows should automatically install the new driver. To
verify this this, please go to Control Panel and then choose De-
vice Manager. You should see the ESATTO listed under “Ports
(COM & LPT)” and described as “Silicon Labs CP210x” (in order
to check, you can disconnect and then reconnect the ESATTO
USB cable and see how Windows lists it).
If you can’t find it, Windows is not able to automatically install
the ESATTO driver. In order to do this, please follow this proce-
dure:
1)go to "Device Manager”
2)locate "CP2102N USB to UART Bridge Controller" under
"Other devices"
page 4
CAUTION
In order to correctly use ESATTO, you have to connect it to your telescope. First you need to connect the optional tele-
scope adapter, and then install ESATTO to the adapter, locking it by using the supplied Allen screw (ESATTO 2 "only) or
the three thumb screws (ESATTO 3” only). The installation procedure changes based on the telescope model and adap-
ter you have so please refer to the following information. To test connectivity from Windows or your mobile device, you
can proceed with the ESATTO first use without the focuser being installed on the telescope, following the steps outlined
in this user manual.

On the left, select the proper COM port number assigned to the ESATTO by the computer and click on the “Connect” but-
ton. You will see the lights on the right side of the win-
dow become green:
1) if you connect ESATTO to your computer only with
the USB cable, you will see a green light illumina-
ted in the to the “Internal temperature” row
2) If you have connected an optional temperature sensor, you will also get the green light in to the “External temperatu-
re” row
3) if you power the ESATTO also with an external power source (a 12V battery by using the supplied cigarette plug cable,
a 12V AC adapter with at least 1A and Ø5.5/2.5mm connector or the EAGLE power cable to power it through the EA-
GLE) you will get the green light corresponding to the “Power supply from 12V DC” row.
Moving the ESATTO focuser is very easy. You can do this in diffe-
rent ways:
1.Move the slider until you reach the desired position and press the
GO button
2.Double-click on the POSITION area, enter the number you prefer
and then press the GO button
3.Double-click on the number below the STEP label, insert the
number you wish and press the < or > buttons to move the focuser
by the number you entered. Press the << or >> buttons to move
the focuser by 10 times the number you entered.
You will see the focuser moving and you will also see the focuser
draw tube moving in the software display, this is designed to let
you easily understand that the focuser is actually moving - Useful
in remote operations where you can’t look directly at the focuser.
At any moment you need to stop the movement of the focuser,
press the STOP button in the lower part of the window.
page 9
What happens if I can’t connect by pressing the “Connect” button?
At this stage, if you can’t connect to ESATTO by pressing the “Connect” button, please check the COM port number that
your EAGLE or personal computer assigned to the ESATTO. To do this, go to Control Panel -> Device Manager > Ports
(COM and LPT) and search for the ESATTO COM port number. This is the number you have to select in the ESATTO Ma-
nager software, before attempting a connection.
NOTE
If you can’t see any movement, maybe you set a too small
value to be seen. Please remember that, for the ESATTO
microfocuser, 1 step is only 0.04 microns!
NOTE on internal temperature values
Here you can read the internal motor temperature, it’s normal
to see values from 10 to 50 °C.
PrimaLuceLab iSrl ESATTO user manual
Thanks to the use of internal sensors, every ESATTO micro focuser is already calibrated and you don’t need to start a new
calibration in order to set the minimum and maximum position of the focuser draw tube. But, if you need for any reason,
please follow this procedure.
Press the Calibration button, a new window will appear
asking you confirmation, press Yes button to proceed.
You will see the ESATTO micro focuser draw tube moving
searching for the minimum and the maximum position.
Please wait (usually 2-3 minutes) and the new calibration
will be automatically saved by the FOCUSER Manager
software.
Calibration data is automatically stored in the ESATTO’s memory so you should not need to repeat this step, even when
changing between computers.
page 10
NOTE: if during the focuser movement you see a very small shift of the image, this is normal and it’s caused by the spe-
cial modified Crayford design to let the ESATTO have a higher load capacity than standard Crayford focusers.
What happens if I see the focuser moving but it stops abruptly?
This typically means that the ESATTO does not have enough power caused by being only connected via USB power, to a
personal computer with USB ports that deliver less than 0.5A. In this case you must also connect the power port on the
ESATTO to a 12V power source and restart the FOCUSER Manager software.
PrimaLuceLab iSrl ESATTO user manual
As you will read in the following paragraph, ESATTO robotic microfocuser includes
also a WiFi connection (to let you control it without the need of a personal computer)
and the ESATTO Virtual HandPad. You can use the Virtual HandPad wirelessly via
WiFi, or via USB using the FOCUSER Manager software. Using either, you can save
up to 9 preset positions, for example to let you recall the focus position of a specific
camera or a visual accessory like an eyepiece.
In order to save a new position in the Virtual HandPad, you first have to move the
ESATTO focuser to the position where your telescope is in perfect focus (you will
