Just bought a Renishaw MP7 probe at auction and it is without the optical receiver. Nearly fell off my stool at the price of a new one.

Is there any way I can read the optical signals without spending loads of money?

I could always access the head directly and make a cable connection which was my intention when purchasing but the contact electronics looks well made - shame to waste.

If i cant access the optical signal is there any post processing circuits available to clean up the raw head signals and give a clean digital output?

Any other solutions?

Cheers
