1. COMPLIANCE OF SAFE REPAIR
Be sure to read this Service Manual before providing services.
In the projector, full consideration is taken to ensure the safety for fire, electric shock, injury, harmful radiation,
and substance. Therefore, observe the notice described in this Service Manual so that safety is kept when
providing services. Moreover, be sure to observe the notice described in the Instruction Manual.
Pay attention to the following during service inspection.
1-1 Cautions during disassembling and assembling
1. This equipment contains parts under high voltage. When making repairs, etc. Be sure to pull out the power
plug beforehand to insure safety.
2. Parts may be very hot immediately after use. Make sure the equipment has cooled off sufficiently before
carrying out repairs.
3. Make sure that parts and screws and wiring, etc. are returned to their original positions. Tube, tape and
other insulation materials have been used for safety reasons. The internal wiring has been designed to
avoid direct contact with hot parts or parts under high voltage when using clamps or other tools.
4. The parts used in this device have special safety features such as flame-resistance and anti-voltage
properties. When replacing parts, always use parts supplied from the factory.
5. After finishing operations make sure that all parts and wires have been returned to their original position and
that there has been no deterioration of the area around the location that was worked on.
6. Be sure to use an earth band (wrist band) during repair and inspection.
1-2 Lamp
During current conduction, the lamp is in the high-temperature state. In this case, pay careful attention
because a high voltage is used. When replacing a lamp, replace it after confirming that the lamp has cooled
sufficiently.
1-3 Lens
Do not look into the lens during projection. This damages your eyes.

3-2. RS-232 Settings
Interface and Requirements
The RS-232 Commands use only ASCII characters which can be entered
using a typical terminal emulator like Windows HyperTerminal with
the following setting:
Bits per second: 19200 (Delta Mode: 115200)
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None
Note that each input character will be echoed on the terminal by MCU and
there is no need to set the local echo “ON” with the terminal setting.
When using “Delta Mode”to operate projector, please use
baud rate “115200”to set and communicate.
When using “Normal Mode”to operate projector, please
use baud rate “19200”to set and communicate.

11 of 73
A. Use RS-232 comment to Retrieve Error Code
Step0. A. Connect the AC power of the projector and have the projector in standby mode.
Step1. A. Connect the RS-232 cable between the projector and the PC.
B. Open a terminal program (e.g. Tera Term) with the following setting, baud rate 115200,
Databit: 8, Parity: none, Stop: 1bit, Flow control: none.
C. Press keypad “Menu”+“Input” (for 3 seconds). And, RS-232 mode systems will feedback
“Delta Mode”.

12 of 73
If terminal show “Delta Mode”, it is entry Delta UART Mode
D. Please key in “op prerr”, and then it will show all accumulated history error codes.
And, the first error code will be the current root cause of defective symptom. Then, please
go to error code list to contrast to actual root cause.

13 of 73
E. After getting and confirm the error code from RS-232 tera term systems, please select
“File”, and then go to select “Exit”.
And, the RS-232 tera term system will be closed and exit.
F. After exit the RS-232 tera term system, please turn off the projector. And, then turn on the
projector again. The projector will go back to the normal mode.

14 of 73
B. Use the RJ-45 comment to Retrieve Error Code
A. Connect theAC power of the projector and have the projector in standby mode.
B. Connect the RJ-45 cable between the projector and the PC. And make sure that the two LEDs
of the RJ-45 module are lit after connecting the RJ-45 cable between the PC and the projector.
If the LEDs are not lit, please send the RS command “eco.net.pow = 0” on the terminal to turn
on the RJ-45 module.
C. Properly setup the IP for the PC and make sure that the PC and the projector are in the same
subnet. For example, the default IP of the projector is 192.168.0.100. So the IP of the PC
should be set as 192.168.0.99 for example.
D. Key in the projector IP on the web browser (the recommended web browser is IE 6.0 or later
version, the default IP is 192.168.0.100) to see the embedded webpage. The IP can be
accessed via the RS command “op net.ipaddr ?” with a terminal program.
