PIIC iX Rev. B compatibility with M4841A

Hello all, Just wondering if PIIC iX requires the M4841A to have a specific Firmware revision to operate. Currently all of my M4841As have Firmware Rev. C.00.58, but I have heard that Firmware Rev. D.00.22 is better/more compatible with PIIC iX. We are running PIIC iX Rev. B. I have not had any reported issues of our C.00.58s not working, but I just wanted to confirm and be sure there shouldn't be any issues. Thanks In Advance!!
