INCREMENT_ and DECREMENT_operations

These operations are used when you want to increment or decrement the excisting value.
The response consists of a PAK (0x1E) followed by the initial operation sent, except for
byte 11, which carries an operation validation code, 0x01. Total packet size is 33 bytes.
5.5

EXECUTE_operations

An EXECUTE_operation triggers a pre-programmed algorithm in the firmware to execute
a certain chain of events. The EXECUTE_operation does not contain any parameters to
indicate a desired value, but simply executes the algorithm assigned to it.
The response is equal to that of the INCREMENT/DECREMENT_operations (see 5.4).
5.6

DESCRIPTOR_operations

To aquire the valid range of an operation, set byte 8 (operation type) to 7 (DESCRIPTOR)
fill in the operation number and send the packet. A successful response will consist of
PAK (0x1E), followed by the standard 32 bytes.
5.7 Example of setting protocol parameters and
sending a command in CMD window
Setting up the COM port, and sending a "poweron" command, where "poweron" is sim-
ply a binary-file with the appropriate packet for turning the projector on:
This returns, when successful, an acknowledgement as described in chapter 5.2 ,
and turns the projector on.

OSD feedback

RS232 control commands will not produce any OSD feedback. Only keypad and IR
remote control will produce OSD feedback.
