Parameters
src_type - EDID
source type (usually output) (see
Section
6.3 EDID Source
)
src_id
- number of chosen source stage (1.. max number of inputs/outputs)
dst_type - EDID destination
type (usually input) (see
Section
6.3 EDID Source
)
dest_bitmap
-
bitmap representing destination IDs. Format: XXXX…X, where X is hex digit. The binary
form of every hex digit represents corresponding destinations. Setting ‘1’ says that EDID data has to be
copied to this destination
Response Triggers
Response is sent to the com port from which the Set was received (before execution)
Notes
Destination bitmap size depends on device properties (for 64 inputs it is a 64-bit word)
Example: bitmap 0x0013 means inputs 1,2 and 5 are loaded with the new EDID
