Encoder Installion. THIS SITE HAS BEEN TESTED WITH: IE5+, NetScape 7, and Opera 7, no problem were found.

Encoder Installion.

AZ/EL (quadrature encoder) Interface, to 7 segment Display, F1EHN, or VK3UM Tracking System.
Resolution, Either 0.01, Binary Mobe, or 0.1 degrees, BCD Mode. Must be BCD Mode for 7 Segment Display and VK3UM Tracking Board.

     Down Load AZ, EL Quadrature Encoder Schematic:    

EncoderBoard-Sch.gif (731601 bytes) This Schematic is in the PDF File and may be easier to view, this Image is FULL Letter Page size. 

PDF File with schematic, calibration, and Silkscreen  It is best to "right" click the PDF file and save as?? 

Below is the method I use to rotate the Encode for AZ Control

I realize there are many methods and techniques that can be used to install the Encoder drive mechanics, this for me is a very easy and inexpensive method and is working for me on two Dishes.
The objective is to attain 30 to 65,000 Quadrature Pulses in 360 degree rotation.
