If you want to install ARCO rotator on one of the ESATTO focusers, you have to add one of the many available optional 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 adapter and tight the 3 grub screws (that are inserted in the ARCO body) by locking it to the adapter. Now you can connect one of the many camera adapters of visual back, the same you can connect to the ESATTO draw tube. Do not over tighten the grub screws otherwise you may ruin the thread or the inner adapter.
Please note: Since ARCO is designed to be as close as possible to ESATTO, you can use the shorter cable to interconnect the two.
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.
ATTENTION: On the port of the ARCO rotator, the arrow position on the cable’s connector has to correspond to the white point. On the ARCO port of the ESATTO, the arrow position on the cable’s connector has to be set to the side of the white label with ESATTO serial number.
