Notes
• When commands are transmitted serially, wait for the reply of the projector (acknowledge or not acknowledge) before sending the next command.
• Adjustment commands include “ARG” (increase adjustment value) and “ALF” (decrease adjustment value). For usable items (marked "Yes"), send after the
selection command.
• The "Yes" marks in the input source columns indicate that that command can be used.
