Simple hardware for Endat 2.2 implementation

Hello, I recently received an optical encoder from Heidenhain. It works with the Endat 2.2 protocol. I would like to use this encoder with a dSpace station, using parallel I/O connection. ...

Dave,

Thank you for your answer.

the encoder is an heidenhain EQN1325, using version 2.2 of the Endat protocol. I'm sending you the datasheet of the encoder and the documentation about the Endat 2.2 protocol by e-mail.

The dSpace machine is simply a PC with a DSP board, the goal of my work is to control position of a small motor. All the control of the motor is implemented using Simulink in the dSpace computer. To control the position, I need to measure the real one, using the digital I/O pins of the DSP board. This is why I need to generate position from the encoder in a parallel word.

Thank you very much for your help,

Samuel.
