Hi,
Jukka is watching this mailing list as well so he may reply directly. However, as far as I am aware, the open-source implementation was created exactly for the purpose of enabling 3rd party implementations.
For protocol details, you can take a look at this document: http://mrf.fi/fw/DCManual-191127.pdf
Protocol details can be found in chapter 1.3, page 9 and forward.
Best regards,
Timo

That I don't know, but I would guess so.
There is github project with VHDL code by the developer (Jukka), for example:

Hi Guobao,
Thanks for the quick reply and the links. Does this mean that the MRF protocol is proprietary to MRI.fi? Can 3rd parties develop I/O devices that interact with the MRF timing system?
Thanks!

Rich,
Not sure whether I can remember I have seen a spec of MRF.
We do use its user manual, available from its home page:

Hello,
I'm developing a requirements document for an EPICS-based system and I'd like to include the MRF timing protocol explicitly, however I'm having trouble finding any links to an actual spec for it. I can find lots of folks describing it and presentation their use of it, but I can't find an actual link to where the official MRF spec is hosted. Any thoughts?
Thanks in advance,
Rich Evans (NASA GRC-ATF)
