The following table lists the identifiers of the binary operator that will be applied.

'Source' is the bitmap or the writing transferred with the command, whereas ‘destination’ is the

display board area on which it will be applied.

Code

Operation Executed

No Operation: Copies the pixels overwriting the previous status

NOT: Inverts the source values and copies them to the destination

AND: Only the pixels active on the source and on the destination remain lit

OR: Only the pixels turned off on the source and on the destination are turned

off

XOR: The destination pixel is inverted only if the corresponding source pixel is

lit.

NOTE: Adding the value 128 (80 hex) to the binary operator, the command is processed regularly,

but the display board is not updated. This option can be useful when more than one command

must be sent to the display board (for example more than one writing in various positions) and it is

required that the display be updated only after the last command has been sent.

Below is a list of the various commands which can be used in the Command field of the graphical

record:
