Peter, today I tried again and the result is the same as before - "fault" led is turned on and I do not see 8i20 in "Show HAL config" under Pins -> hm2_7i43 -> 0. I have: 1) +55 VDC applied to motor power; 2) +12 VDC applied to "enable" input; 3) checked the cable between 7i43 to 8i20 again (including the ttl <--> rs422 converter in the middle) - all the wire leads match the firmware pinout, SN75179 pinout and 8i20 serial port pinout I do not have motor attached. There are 5 LEDs turned on: 1) PWR 2) LV STATUS 3) ISO PWR 4) HW ON 5) FAULT The only LED that is not turned on is STATUS. Are there any testing tools that I could try out to find, why does not LinuxCNC receive any response from 8i20 drive?
