“…the encoder intended to be used is:
-             Read head: T2601-15M or T1611-15M (this depends on availability, the arc can be resolved with a linear and a rotary encoder head, it is actually more a matter of how the scale is mounted and that will be done on an arc)
-             Interface: Ti20KDA06A, that is 20,000x interpolation to get the highest resolution. Note, on the interface one has to check with controls what options they may want to see, for that see below link. What is of importance are the last for letters (i.e. currently the …A06A, this is our usual default):
o            First A: this is for alarm outputs. I have to admit, I have no real clue on that, this needs to come from controls
o            06 is the max output frequency. 6 MHz in this case, often controllers have a limit of what they can take as maximum. The 6MHz is for vibrations check more than sufficient
o            Second A: some options regarding what kind of signals are output, also here this is a controls related question.https://www.renishaw.com/media/pdf/en/257d836362cd4e8189908521185ff4bd.pdf”

Encoder Simulator

Chris Ford has an encoder simulator in lab3, with documentation here:  UDP Encoder Interface (rix Mono Encoder).  He also has committed lab3-caf-encoder.cnf to lcls2 GitHub in psdaq/psdaq/cnf/.
