15 pin assy jack on rear of 6600M

1) I am trying to use the new filters in the latest update concerning digital operation. However when I go to DIGU and using the 15 pin assy jack on the rear of my 6600m there is no output. However if I go to USB then I get full output from my SCS Pactor controller into this 15 pin input. My question I guess is two fold 1- why is this no output when going to DIGU vers USB and 2- Do the new filters work on digital modes I assume no so what is my option to use these filters .
