Installing ARCO on ESATTO focusers
If you want to install ARCO rotator on one of the ESATTO focusers, you have to add one of the many available op-
tional adapters based on the models of ESATTO focuser and ARCO rotator you own. First of all please connect the
optional adapter to the ESATTO focuser, by threading it to the draw tube. Then connect ARCO rotator to the adap-
ter and tight the 3 grub screws (that are inserted in the ARCO body) by locking it to the adapter. Now you can con-
nect one of the many camera adapters of visual back, the same you can connect to the ESATTO draw tube.
Now you can connect the cable from the ARCO port of the ESATTO to the port below the ARCO body.
Take great
care when connecting the cable to the ARCO port of the ESATTO and the port below the ARCO. Take a look
at position of internal pins in the connector and rotate the cable connector until it corresponds to the port
on ESATTO or ARCO. Then connect the cable with a gently press. If it doesn’t fit, please do not press too
much the connector otherwise the internal pins may break.

NOTE
Do not over tighten the
grub screws otherwise
you may ruin the thread or
the inner adapter.
NOTE
Since ARCO is designed
to be as close as possible
to ESATTO, you can use
the shorter cable to inter-
connect the two.
