MC 500V Minimaster retrofit

Ok for today, trying to be as systematic as possible. Hooked up encoders, supplied 12v as required, I get an index pulse = true but thats all. On my 7i77 my cr15 LED is solid green, while cr16 is solid red. never changes. Does this mean some sort of communication failure? Just trying to get some of the encoder stuff working before I hook motor power up. I can see all the pins, just cant get any info to them, or it seems from them.

A 7i77 when powered up and happy will have 4 yellow leds. CR15 Green Lower right Field I/O activity CR16 Red Lower right Field I/O fault. In normal operation CR1 through CR7 must always be on. At power-up, CR15 should be off and CR16 on. The red LED CR16 indicates a watchdog fault, which is expected before host communications are established. Once running, CR15 should blink at about 1 Hz for a 1 KHz update rate, and CR16 should be off. Note: CR15 and CR16 are only present in revision B or greater 7I77 cards.

Yeah the red never goes off. And the green never blinks. So maybe the cable could be bad?

Sounds like the 7I77 is jumpered for setup rather than operate mode
did you change any jumpers?

W4 and W12 must be set for operate mode (Left position) for normal operation

thank you it was jumpered for setup. resolved that, I get all the yellow leds lit, but the cr15 is out and cr16 (watchdog?) solid red.
Linuxcnc ver 2.7.3 while reading posts last night maybe need to revert to older version?

Thats the expected LED display when LinuxCNC is not running or perhaps not setup correctly
