Got it. Thank you @Tony.

I'm trying to control PMAC through serial port from a terminal. I tried different terminals, successful with some, e.g., Tera Term, and unsuccessful with others. It seems it's due to the terminator sent at the end of the command. What's the correct format for the command sent and status read back?

I connected a Renishaw 26-bit BiSS-C encoder to the PMAC and I'm monitoring the two encoder signals with a oscope. In PEWIN the Cts Per Unit is set to 1, and the position shows 107500. On the oscope it shows 631787 (26-bit position only, status and CRC bits removed). The waveform format is exactly as defined in the BiSS-C protocol, and CRC is correct, so I assume there's no error/noise causing measuring problem. Then how could the two readings be so different? Is the position window in PEWIN showing the raw read back value from the encoder?
