JMI DRO Encoder for JMI Focusers
The encoder assembly is attached to an NGF or EV focuser (specify complete model number). A DRO hand unit or Smart Focus system (see below) is also necessary.
This is the portion of a DRO system that attaches to the JMI EV or NGF focuser. (Specify the focuser model.) A DRO Hand Unit or Smart Focus is also necessary for proper operation.
Due to the modular design of the JMI EV focusers, they can be very easily upgraded after purchase to include DRO. If you do not have a motorized version, see our EV Focuser Individual Parts for a motor upgrade. For a visual description of the system see Motor Control Diagrams where you can compare DRO, PCFC and Smart Focus.

For all JMI focusers we need to have certain information in order to supply the correct parts. When ordering, please place a note in the shopping cart Comments area identifying the focuser. For Event Horizon (EV) focusers, "EV" is sufficient information. For all other focusers, specify the model and date of purchase (date of manufacture if known).
A digital picture is "worth a thousand words" in describing the specific model. If you email a picture, please give us your Order ID along with your Name. If we need more information, we will contact you.
