Hello everyone,
I have a problem,few days ago, I have to be repaired
an interface called PC Acq. Mod DM302 manufactured by SPEX;
This card receives a signal from an optical part (which is directly
connected to a polarizer) and sends its output signal to the polarizer
(thus creating a feedback) some days no longer works;
The question is: anyone has any information on this card (DM302
manufactured by SPEX) for example, wiring diagrams and user manual.

Thanks to all
Joseph
