Installing SESTO SENSO 2 on the telescope’s focuser
In order to connect SESTO SENSO2 to the focuser of your telescope, remove the manual focus micrometric knob by un-
screwing the screw normally present on the knurled knob. After pulling it out, you also need to disconnect the coarse fo-
cuser knob, by means of an allen screw on the knob. On some plastic-covered focusers, you need to remove the plastic to
access the disassembly screw. Connect one of the bushings you find in the SESTO SENSO 2 box (based on the diameter
that fits your focuser) to the small focuser shaft of your focuser.
Now you can connect SESTO SENSO 2 to your focuser by paying attention to centering the micrometric pin with the pre-
assembled bushing on SESTO SENSO 2, until it stops. By using the provided allen screw, lock the 2 grub screws that fix
the pre-assembled bushing on SESTO SENSO 2 to the bushing you just installed on your focuser's shaft.

NOTE
in order to work, SESTO
SENSO 2 requires your
focuser to have the micro
metric knob.
PrimaLuceLab iSrl SESTO SENSO 2 user manual
Then, by using the provided allen screw, please fix the screws that fix the outer ring of SESTO SENSO 2 to your focuser.
Finally, use the allen screw to lock the 3 small grub screws fix the outer ring of SESTO SENSO 2 to your focuser.
page 5
NOTE: After installing SESTO SENSO 2 on your focuser, check the smoothness of the movement keeping SESTO SENSO
2 powered off and then manually moving the focus knob of your focuser. The presence of SESTO SENSO 2 will make the
movement harder (since the motor is connected) but the motion must still be uniform. If you notice an uneven move-
ment, repeat the installation procedure.
NOTE: SESTO SENSO 2 connects to several focusers that may have different machining and tolerances precisions. Fo-
cusing accuracy, especially when using automatic focusing procedures, depends on the focuser mechanics and not only
strictly on SESTO SENSO 2. If your focuser has an important backlash, you can adjust the backlash parameter in the
software.

Controlling SESTO SENSO 2 with EAGLE or computer with Windows OS
SESTO SENSO 2 can be controlled with the EAGLE or any external computer that comes with Windows operative system
(at least version 7 64 bits). In the SESTO SENSO 2 package you can find a 12V power cable with cigarette plug and a PC
connection cable for USB port. Connect the USB-C cable to the USB port of your EAGLE or personal computer. You will see
the PWR LED on (this means SESTO SENSO 2 is powe-
red) and, after a few seconds the Wi-Fi LED will be on
too and this means that also the SESTO SENSO 2 WiFi
connection is ready to be used.
When you connect it to USB port of the EAGLE or of an
external computer, SESTO SENSO 2 should be automa-
tically detected and Windows should automatically
install the new driver. In order to check this, please go
to Control Panel and then choose Device Manager. You
should see the SESTO SENSO 2 listed under “Ports
(COM & LPT)” and described as “Silicon Labs
CP210x” (in order to check, you can disconnect and
then reconnect the SESTO SENSO 2 USB cable and see
how Windows lists it).
If you can’t find it, Windows is not able to automatically install the SESTO SENSO 2 driver. In order to do this, please follow
this procedure:
1) go to "Device Manager”
2) locate "CP2102N USB to UART Bridge Controller" under "Other devices”
3) make a mouse right-click and select "Update Driver Software”
4) select the second option “Browse my computer for driver software” in order to install the driver from a specific folder
5) select the folder where you saved the content of the SESTO SENSO 2 software package you downloaded from our
website
www.primalucelab.com/astronomy/downloads
Please remember to unzip the file you downloaded before starting the installation of the SESTO SENSO 2.
6) at the end of the procedure, a message will appear indicating the correct installation.
Now, under “COM and LPT devices”, you will see a new COM port (in this example COM16) which is the one used by your
computer to communicate with SESTO SENSO 2.
page 6
NOTE
If the driver is not correctly installed in your Windows operative system, SESTO SENSO 2 won’t be able to connect to
your EAGLE or external computer and it won’t work. So please check that the COM driver is correctly installed before
proceeding to the next step.
