i swapped the madi input but it is not working and there is a constant red light coming on the card what does it mean and on the hammer fall settings the madi is not sync so what would be the reason

"set the card to internal/ master ? and coax and optical loop back",i really dont how to loop back ,please let me know how can it be done , if you have a screen shot how to set the card to internal or master please send it to me so i can follow your instructions , i run foh and monitor desk using madi so i use the same my stage mix cable to record but still i am not able to record ,my allen heath desk is got 4 madi outs and signal is passed from all the outs but it doesnt appear in my neundo software ,

i selected all the hammer fall inputs in the recording software and i can only play back any track if it is assigned to stereo out only ,

i really appericate your patience in answering my doubts , thanks a ton

1)i looped the output to the input then i got a green light on the rme card :-) and i could record one channel of  whats playing back, this makes me feel better that my card is working and when i put ten tracks and play them they are coming on my allen heath console but i am not able to record ,

2)i could'nt figure out whats internal / master mode i dont know where is it on the hammer fall mixer or my pc,

3)when i plug in my madi cable which comes from the allen heath console there is a red light which glows on the rme card and thats the error light **but when i use another small patch cable and when i loop from input to output  the rme card is got a nice green light,  what is the reason for the colour change and why am i not able to record all my channels

Have you tried using your longer cable as a loopback? May be a faulty cable. Or as MC said a sync mismatch.
