Replaced Rambo board and not recognizing MMU2

 

Replaced the Rambo board on my MK2.5S/MMU2S and installed the latest firmware. Support menu now shows MMU2 as N/A. On power up lights on MMU2S show 1-3 solid green, 4 flashes both red and green slow and 5 flashing green fast. then they go out for a few seconds and then all flash both red and green. The idler homes but the selector does not move. Power to the MMU board reads 12 VDC.

Any ideas??

Thanks

If you running the version 3.13 firmware, there is a new setting to enable the MMU2.
