Settings for projector preferences are either Transferable or Projector-specific:
Transferable: Valid for any projector of the same model. Single DTA parameter = T.
Projector-specific: Unique to an individual projector. Single DTA parameter = P.
example:
($DTA? T)
(BDR! 09600)
(LPI! 00345)
Etc....

($DTA? P)
(CTM! 001 002 00000 000 01187)
(CTM! 002 007 05400 012 043)
Etc....

DoWnloaDIng PRefeRenCes To a PRojeCToR
To download preference settings to a projector, just send the various settings as separate
commands—DTA is not used. Take special care when sending BDR (Baud Rate) and ADR
(Projector # or Address) messages, as they change the way your network operates and you
may accidentally break communication. For example, BDR should always be broadcast to all
projectors or you will be unable to talk to some projectors.
DTl DeTaIl
Use DTL to set the detail for RGB and video images.
DTT DeTaIl ThResholD
Sets the minimum change required before the detail (DTL) function is activated. This sharpens
images without increasing background noise.

The EBB control is only active when Edge Blending (EBS) and Black Edge Blending (BEB)
have been enabled. The particular edges that have been blended with the Edge Blending (EBL)
command will be active for blending the black levels. For example, you cannot adjust the Edge
Blend Black level for the top edge, if there is no edge blending active for the top edge. Similar to
the EBL control, data can be specified by zones or edges, or by index.
