Alpha-Link firmware history

Alpha-Link firmware can only be updated via the Mixpander PCI card. There is generally no reason to update Alpha-Link firmware.

Alpha-Link AX firmware

V2.3 (v9.hex, 28 Jan 2008)
   - ADAT audio popping problem solved

V2.4 (v10.hex, 21 Feb 2008)
  - AX had locking problems in following conditions :
    96Khz +  Adat-Channel-Status = Use + Adat SMUX = ON

V2.5 (v11.hex, 8 April 2009) has following modifications implemented:
  1) MADI 96Khz High Speed (Frame Pattern) transmitter problem solved.
      This will solve the MADI locking problem that other devices have when working at following conditions :
      96Khz +  MADI Frame Pattern mode + 64channel Mode (or or 56ch mode in combination with vari-speed))
      In the above mentioned conditions, the 'foreign' device sometimes lost lock.
  2) MADI 57th non-audio channel compliant
     Alpha-Link AX can withstand a 57th (and subsequent) non-audio channel
  3) Occasional ADAT output channel shift solved, happened in following situations :
        - working stand-alone
        - Too many MADI channels are routed to ADAT out
