9. INTERNAL ERRORS
Error data is returned to the external control unit when an error has occurred.
9.1 Internal Error Data Status (Internal Error Status)
Character HEX Definition
‘E01’ 45H 30H 31H Lamp did not light
‘E02’ 45H 30H 32H Lamp life exceeds guaranteed time
‘E03’ 45H 30H 33H IIC ACK error occurs
‘E04’ 45H 30H 34H Filter cover on the bottom of the unit is displaced
‘E06’ 45H 30H 36H Lamp suddenly goes out (Lamp Shut Down) while
projecting
(in Power ON mode)
‘E07’ 45H 30H 37H Fan is locked
‘E08’ 45H 30H 38H I n t e r n a l t e m p e r a t u r e i s t o o h i g h .
‘E09’ 45H 30H 39H Temperature around air intake is going up abnormally.
‘E0B’ 45H 30H 42H Error occurred with the initialization of decoder.
‘E0C’ 45H 30H 43H Initialization of Video Sources (Areas) data was failed.
‘E11’ 45H 31H 31H Sub microcomputer is not boost up correctly.
‘E12’ 45H 31H 32H Initialization of DDIC/DDCTRL was failed.
‘E20’ 45H 32H 30H Sl ee p tim e fu nc tion wo rk s a nd l am p wa s li t off .
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’:
‘＆’ ID SP ‘E03’ SP ‘00A0’ SP ‘1F20’ CR
11 9.3 Internal Error Data Reply Timing
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.
That is, if an internal error
occurs, the Projector retains the internal error data, returning it in order of precedence a request
for tally (response) data is received. Once transmitted, internal error data is deleted from the
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.
Switch ON the projector’s MAIN POWER

* Note that the acceptance/non-acceptance condition of a command differs depending on the operation
mode.

11. SOURCE
The input signals to projectors can be Computer Sources and Video Sources.
Although the specific signal names are not given to Computer Sources , these can be specified with the
combination of Frequency and Resolution.
Video Sources are as follows:
NTSC(480i)
PAL/SECAM
NTSC(480p)
PAL(625p)
DTV(720p)
HDTV(1035i)
HDTV(1080i)

RGB signals or YPbPr signal is fed to BNC input terminal , the different Source No is given even if the same
type of Source.
※ Note that the acceptance / non-acceptance of a command is differ depending on the Source
(Area) actually registered on the Projector.

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).
