Install 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 unscrewing the screw normally present on the knurled knob. After pulling it out, you also need to disconnect the
coarse focuser knob, by means of an Allen screw on the knob. On some plastic-covered focusers, you need to re-
move 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.
NOTE
SESTO SENSO 2 is designed to be connec-
ted to 25mm shaft. If you have another dia-
meter, you may add the optional 26, 33 or
37mm adapters. Please refer to page 25 in
order to know how to install the adapters.
PrimaLuceLab SpA 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 SE-
STO 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 movement, repeat the installation procedure.
NOTE: SESTO SENSO 2 connects to several focusers that may have different machining and tolerances preci-
sions. Focusing accuracy, especially when using automatic focusing procedures, depends on the focuser me-
chanics and not only strictly on SESTO SENSO 2. If your focuser has an important backlash, you can adjust the
backlash parameter in the software.

Install SESTO SENSO 2 in EAGLE or Windows 7/8/10/11 computer
SESTO SENSO 2 can be installed in the EAGLE or an external computer running Windows 7, 8, 10 or 11 operating
system. 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 SESTO SENSO 2 power cable to a power sour-
ce (SESTO SENSO 2 power port is Ø5.5 ø2.5mm with
center positive) and then connect the USB-C cable to the
USB port of your EAGLE or standard computer. You will
see the PWR LED on (this means SESTO SENSO 2 is
powered) and, after a few seconds the Wi-Fi LED will also
be become lit - This means that the SESTO SENSO 2 is
online and the WiFi connection is ready to be used.
Once connected the SESTO SENSO 2 should be auto-
matically detected and Windows should automatically
install the new driver. To verify this this, please go to Con-
trol 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 SE-
STO 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" un-
der "Other devices"
!

PLEASE NOTE
In order to correctly work, SESTO SENSO 2 requires an external 12V power supply and by connecting it to the
USB port of a computer is not enough. Always connect an AC power unit or a 12V battery to the SESTO SENSO
2 12V power port before connecting the USB cable to the computer.
