IMPORTANT

The active station reads and writes data from and to
the markers of the remote station. At the same time,
the remote station has read and write access to the
same marker range.

Ensure that both stations do not have write access to
the same markers simultaneously. The last write
operation will be the one that is retained.

Example:

READ 1MD2 -> 1MD2

WRITE 1MD3 -> 1MD3

The GFX device accesses the markers with station
address 1xx... These markers correspond to the local
markers MD2 and MD3 in the remote station.

These marker double words contain:

MD2, MW3, MW4, MB5; MB6, MB7, MB8, M33 to
M64

MD3, MW5, MW6, MB9, MB19, MB11, MB12; M65 to
M96
