5. ID
Numeric characters are used to identify an individual Projector when two or more Projector units are
connected to a single control machine.
Setting separate identification numbers for each Projector allows independent control of each
Projector unit.
# Assignable ID numbers
‘0’(30H) ‘8’ (38H)
‘1’(31H) ‘9’ (39H)
‘2’(32H) ‘A’ (41H)

‘7’(37H) ‘F’ (46H)
* Factory set ID is ‘1’ (31H).
ID number ‘0’ (30H) should be used when assigning all connected Projector units for batch operations.
This means that when assigning independent ID numbers to multiple units, 15 of the 16 assignable
numbers (from ‘1’ through ‘F’) can actually be used for registration.
Please note that tally (response) data is not returned from the projector when the global ID assignment
function (0) is used.

7. PARAMETERS
There are three types of parameters:
1.Indicates the numeric value.
2.Indicates the ON/OFF status.
3.Special parameter.
7.1 Numeric Value Parameter
Signed 2-byte hexadecimal code represented by 4 (byte) characters.
Assignable range is between ‘8000’ and ‘7FFF’.
Ex-1) The parameter indicating ‘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)

8. TALLY(RESPONSE)DATA
The Projector will only accept and process data when the ID number included with
the ID-number registered
matches the Projector’s ID, it will return a response to the query from the external control unit. This
response data is called "Tally (Response) Data". (However, when ID = ‘0’, tally (response) data is not
replied.)
The Tally (Response) Data is normally returned within 3 seconds after the data is received.
There are some exceptions, however (e.g. POWER command)
After transmitting data, the external control unit cannot transmit subsequent data until the Tally
(Response) Data is received. However, if Tally (Response) Data is not returned within 3 seconds after
transmitting the data (there are some exceptions such as the POWER command), data transmission can
be retried.

The Tally (Response) Data Parameter is returned when the Tally (Response) Data is issued in
response to a query (request for data). No parameter is returned when Tally (Response) Data
issued in response to a command or when an error occurs.

9.2 Internal Error Data Parameters
There are two parameters for Internal Error Data.
Header ID SP Internal Error Status SP Parameter 1 SP Parameter 2 CR
Each parameter shows the slave address (Parameter 1) and Sub-Address (Parameter 2) when
an IIC ACK error (Error status: ‘E03’) occurs.
The parameter type is "numeric value".
* Two parameters are also returned when an internal errors other than IIC ACK errors occur.
In this case, however, the parameter’s numeric value has no meaning.
Ex) Internal error data when IIC ACK error occurs with Slave address ‘A0H’ and Sub-address of
‘1F20H’:

When returning data, the Projector checks for internal error data. If such data exists, the internal
error data is returned before the tally (response) data is transmitted.

Projector.

10. PROJECTOR OPERATION MODES
This section describes the Projector’s four basic operation modes.
10.1 Standby Mode
The Projector enters this mode when it is plugged into an AC outlet and the MAIN POWER
switch is turned ON.
The lamp does not light and the fans do not operate.
10.2 Power ON Mode
This mode is engaged when the POWER ON command is received and processed
normally in the Standby mode. The lamp is lighted and the fans start rotating. Images can
be projected in this mode.
10.3 Cool-Down Mode
This mode is engaged when the POWER OFF command is received and processed
normally in the Power ON mode.
The lamp goes out and the fans are rotated continuously to cool down the lamp.
To avoid the lamp is lighted again in short time, the POWER ON command is not accepted
during this mode.
The DLA-G3010 series, the Cool-Down Mode time is approximate 90 seconds. The lamp
goes out and the fans are rotated continuously during this mode to cool down the lamp.
The DLA-M2000 series, the Cool-Down Mode time is approximate 120 seconds. The lamp
goes out and the fans are rotated continuously during this mode to cool down the lamp.
After the mentioned time lapse, the unit automatically enters the Standby mode.
10.4 Emergency Mode
This mode is engaged when the projector malfunctions or is improperly operated.
The lamp and the fans are shut down and the MAIN POWER switch is turned OFF.
Non-operation status continues until the reset function is activated.

12. COMMANDS
This section describes the commands that can be used with the Projector.
◇ In the Communication Examples, the ID number registered on the Projector is represented as ‘1’ (31H).
This is the default setting.
◇ "CTLR" refers to transmissions from the external control unit and "DLA" refers to transmissions (Tally
(Response) Data) from the Projector.
◇ "Reply Time" refers to the maximum time required between command reception and return of Tally
(Response) Data. In other words, it refers to the maximum time that the external control unit must
wait for the Tally (Response) Data.
◇ For details on the different parameters, refer to 7. Parameters.
◇ Acceptance or non-acceptance of a command in each operation mode is indicated by "O" (accept) or
"X" (does not accept).
