Hi Rich,

There are several examples of 3rd party event modules.
At KEK, we developed embedded EVR using FPGA for the RF monitoring system.

We are also using the SINAP event modules for BPM. These modules are

compatible with MRF products.

You can check below links for details.

Cheers,
Wang

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)
