ALFE - DMA error

Only for machines with an ALFE subsystem.

DMA is a technique for transmitting data between the AK5 camera head and the LFE board. If no data can be transmitted, this message is generated. Possible causes are:

- Plug of LFE<->AK5 connecting cable is not plugged in properly (on AK5 or on LFE board).

- Break in LFE<->AK5 connecting cable.

- AK5 camera head failure.

- LFE board failure.

The controls continue to operate correctly, but the Teach Trace function is no longer available.
