Problem with memory expansion on a Dataflyer 500

[webmany]

I have a dataflyer 500 connected to an A500.  The SCSI portion of the card works fine.  I am trying to add the memory expansion to the box, but it is not being recognized.  The card does work in an A3000, so it looks ok.

Does anyone know what the jumper settings are supposed to be?  All I can find is the settings for the memory size and type.

The memory expansion is Version 3.

Same thing with that site, only shows the jumpers for memory, but there are other jumpers.
