3.6.1 Numeric value parameters
Signed 2-byte hexadecimal code represented by 4 (byte) characters.
Ex-1)
The parameter indication ‘20’ (decimal):
Since ‘20’ (decimal) is represented as ‘0014’ in signed 2-byte hexadecimal, its parameter is:
‘0014’(30H 30H 31H 34H)
Ex-2)
The parameter to indicate ‘-2’ (decimal):
Since ‘-2’ (decimal) is represented as ‘FFFE’ in signed 2-byte hexadecimal, its parameter is:
‘FFFE’(46H 46H 46H 45H)
3.6.2 Special parameter
The parameters are generally interpreted with ASCII characters.
But some of the commands have a unique interpretation (for the details, see the section on Command sequences).

3.8 Error handling
 An external controller should not transmit the next commands until it receives an ACK that the transmitted unit ID and the
command match.
 The specifications for timeout and retry when an ACK response has not been received are not specified here; the specifications
unique to the external controller may be used.
 If the byte interval is blank for 50 ms or longer, initialize the transmit-receive sequence (the received data is discarded).
 If a unit ID other than its own is received, it is ignored.
 If the unit ID matches but an undefined header command is received, it is ignored.
 If the header command is normal but an undefined parameter is received, it is ignored.
 Even if the command receipt is normal (ACK response) and the parameter is valid, it may be ignored, depending on the state of
the projector. For the details, see the instruction manual for the projector (for example, projector, power ON operation in the
power cooling state, etc.).

3.9 Co unication sequence
[ACK/NACK concept]
When the projector receives a command, it returns ACK immediately
if the command is prescribed. If not, the projector returns nothing.
[Operation sequence]
When projector receives an operation command, it returns ACK
immediately and performs the command operation. However, if the
projector receives the command while user operation is going on, it
only returns ACK for the command but operation is cancelled.
[Reference sequence]
When projector receives a reference command, it returns ACK
immediately, and then transmits related information for command as
response to external controller.
If the projector receives a reference command while in user
operation, it transmits ACK immediately, and then it transmits
response command after the completion of user operation.
This is because of conflict between projector information and the
information passed to external controller via response command
based on timing, if the reference command is approved while in user
operation.
