Quadrature Encoder Operation
The Universal Encoder Interface will accept either single or dual quadrature
encoders. Configuration of the board to accept the encoders is done through
jumpers on J4.
Boards shipped from the factory come defaulted to single quadrature encoder
configuration.
(1)
For dual encoder configurations, the primary encoder is wired to pins 1 to 7 on
the 1492-IFM20 module. (See
).
