1 Safety Precautions

1.1. General Guidelines

· For continued safety, no modification of any circuit must be attempted.

· Unplug the power cord from the power outlet before disassembling this projector.

· It is advisable to use an isolation transformer in the AC power line before the service.

· Observe the original lead dress during the service. If a short circuit is found, replace all the parts overheated or damaged by the short circuit.

· After the service, all the protective devices such as insulation barriers, insulation papers, shields, and isolation R-C combinations must be properly installed.

· After the service, check the leakage current to prevent the customer from getting an electric shock.

1.2. Leakage Current Check

1. Prepare the measuring circuit as shown in Fig.1. Be sure to use a voltmeter having the performance

described in Table 1.

3. Connect M1 to T1 according to Fig. 2 and measure the voltage.

4. Change the connection of M1 from T1 to T2 and measure the voltage again.

5. The voltmeter must read 0.375 V or lower in both of steps 3 and 4. This means that the current must be 0.75 mA or less.

6. If the reading is out of the above standard, the projector must be repaired and rechecked before returning to the customer because of a possibility of an electric shock.

Fig. 1

Table 1

Fig. 2

2. Assemble the circuit as shown in Fig. 2. Plug the power cord in a power outlet.

5 Using the Serial Terminals

SERIAL terminals which are on the side-mounted connection terminals conform to RS-232C standard. This projector can be controlled by a PC which is connected as shown below. Also SERIAL OUT terminal is provided to enable plural projector control.

5.1. Examples of Connection

5.2. Pin Assignments and Signal Names

5.3. Communication Conditions (Factory Setting)

5.4. Basic Format

Transmission from the computer begins with STX, then the ID, command, parameter, and ETX are sent in this order. Add parameters according to the details of control.

PT-D5500U / PT-D5500E / PT-D5500UL / PT-D5500EL

Attention

· No command can be sent or received for 10 to 60 seconds after the lamp starts lighting. Try sending any command after that period has elapsed.

· When sending several commands, be sure to wait for a response from the projector before sending the next command. When sending commands without parameters, a colon (:) is not necessary.

Note

· If a wrong command parameter is sent, the projector will send an "ER401" or "ER402" command to the computer.

· A projector ID supported on the RS-232C interface is ZZ (ALL) and a group of 1 to 64 and 0A to 0Z.

· If a command is sent with a projector ID specified, the projector will respond to the computer only in the following cases:

If it coincides with the projector ID, ID specification is ALL and VPS-SYSTEM is the master, or ID specification is group and Group is the master.

5.5. Procedure of Communication Condition Settings

(1) Press the MENU button.

The MAIN MENU screen will be displayed.

(2) Press the and buttons to select “OPTION2”.

(3) Press the ENTER button. (4) Press the and buttons to select “RS232C”.

(5) Press the ENTER button.

The RS232C screen will be displayed. (6) Press the and buttons to select communication conditions. (7) Press the and buttons to confirm the setting.. (8) Press the MENU button three times.

The on-screen indications disappear, and the system returns to the

normal screen.

5.7. Cable specifications

Note

To connect the computer to the SERIAL terminal, prepare an adequate communication cable that fits to your personal computer.

PT-D5500U / PT-D5500E / PT-D5500UL / PT-D5500EL

6 Using a Wired Remote Control

6.1. Connection Example

When two or more projectors are connected in the system, connect the projectors with the supplied remote control cable to simultaneously control the projectors with a remote control unit through the REMOTE1 IN/OUT terminal. It is effective to use the wired remote control in the environment in which an obstacle stands in the light path or where the system is susceptible to outside light.

6.2. Setting the Projector ID Number for Remote Control

Every projector has its ID number and the ID number of the controlling projector must be set to the remote control in advance so that the user can operate the remote control. The ID number of the projector is set to “ALL” on shipping, and use the ID ALL button of the remote control when using only a single projector.

Procedure of ID setting

1. Change the position of the operation mode selector awitch to “Computer”.

2. Press the ID SET button, and within five seconds use the number (0 to 9) buttons to enter the 2-digit ID number set by the projector.

3. Change the position of the operation mode selector switch to “Projector”. However, if the ID ALL button is pressed, the projector can be controlled regardless of the ID number of the projector

(simultaneous control mode).

· Do not press the ID SET button accidentally or carelessly because the ID number on the remote control can be set even

when no projector is around. If the ID SET button is pressed, the ID number goes back to the one set before pressing the ID SET button unless a

numeric button is pressed within five seconds after the ID SET button is pressed.

· Your specified ID number is stored in the remote control unit unless another one is specified later. However, the stored

ID will be erased if the batteries of the remote control are left exhausted. When the dry cells are replaced, set the same ID number again.

department

7.2. Note for Replacement of P.C.Boards

7.2.1. When replacing the A-P.C.Board

· Transfer the data of the original A-P.C.Board to the new A-P.C.Board using the adjustment software and a personal computer. (If you cannot transfer the data, remove IC2508 and IC2509 from the original board and mount them on the new board.)

* For the adjustment software, consult an authorized service center.

7.3. Replacement of the lithium battery on the A-P.C.Board

Optical block unit (including DMD™ block) , DMD™ drive module, Assembly parts

If the lithium battery will be empty, replace it with a new one (CR2032 or equivalent).

Cautions

· Explosion may occur if replacing the battery with an incorrect one.

· Dispose of used batteries according to the instructions.

8 Cautions for Service

8.1. Servicing Methods

· Never unplug the power cord from the outlet, open the circuit breaker, or perform other procedures to cut off the power line during the operation of any cooling fan.

· Be sure to unplug the power cord from the power outlet before servicing.

Powering off the projector

1. Press the POWER OFF "

10 Replacement of Lamp Unit

Cautions

· Wait until the lamp is cooled sufficiently before replacing the lamp unit.

10.1. Precautions on Lamp Unit Replacement

· Be careful when handling a light source lamp . The lamp may burst if it hit by solid objects or if it is dropped because of high air pressure inside the bulb.

· A used lamp unit may burst if it is handled violently. For disposition of used lamps, request an industrial waste disposal contractor.

· Do not reset the cumulative time, except when the lamp unit has been replaced with a new unit.

· If you continue to use a lamp after the replacement time, the lamp may break.

· Philips screwdriver is necessary when replacing a lamp unit.

Take care not to slip your hand when using a screwdriver.

· A lamp unit is an optional part. Contact the dealer. Replacement lamp unit model No.: ET-LAD55 (single bulb), ET-LAD55W (double bulbs) Rating: 300 W

Long-life lamp unit model No.: ET-LAD55L (single bulb), ET-LAD55LW (double bulbs) Rating: 160 W

· Other lamps than specified above cannot be used. Be sure to use the specified lamp.
