Connection to Analog Sin/Cos Absolute Encoder
The GBL2660 has 4 high-speed analog inputs that can be used to capture absolute angle
position from resolvers or magnetic sensors with sin/cos voltage outputs. The signal must
be 0-5V max with the 0 at 2.500V. Table 3, below, shows the signals assignment on the
25-pin connector.
