■ LEAD-FREE SOLDER

The PWB’ s of this model employs lead-free solder. The “LF” marks indicated on the PWB’s and the Service Manual mean “Lead-Free” solder. The alphabet following the LF mark shows the kind of lead-free solder.

Example:

Solder composition Sn-Ag-Cu Sn-Ag-Bi

(1) NOTE FOR THE USE OF LEAD-FREE SOLDER THREAD

When repairing a lead-free solder PWB, use lead-free solder thread. Never use conventional lead solder thread, which may cause a breakdown or an accident.

Since the melting point of lead-free solder thread is about 40°C higher than that of conventional lead solder thread, the use of the exclusive-use soldering iron is recommendable.

Solder composition code

i n s

(2) NOTE FOR SOLDERING WORK

Since the melting point of lead-free solder is about 220°C, which is about 40°C higher than that of conventional lead solder, and its soldering capacity is inferior to conventional one, it is apt to keep the soldering iron in contact with the PWB for longer time. This may cause land separation or may exceed the heat-resistive temperature of components. Use enough care to separate the soldering iron from the PWB when completion of soldering is confirmed.

Since lead-free solder includes a greater quantity of tin, the iron tip may corrode easily. Turn ON/OFF the soldering iron power frequently.

If different-kind solder remains on the soldering iron tip, it is melted together with lead-free solder. To avoid this, clean the soldering iron tip after completion of soldering work.

If the soldering iron tip is discolored black during soldering work, clean and file the tip with steel wool or a fine filer.

When mounting the monitor, be sure to use a wall-mount / ceilingmount bracket they comply with the VESA-compatible mounting method. SHARP recommends using M6 screws and tighten the screws. Note that screw hole depth of the monitor is 3/8 inch (10 mm). Loose holding may cause the product to fall, resulting in serious personal injuries as well as damage to the product. The screw and hole should come together with over 5/16 inch (8 mm) length of thread. Use the bracket which applied UL1678 standard, and which can endure at least 4 times or more the weight of the monitor.

1-6. HOW TO INSTALL THE MONITOR

■ Mounting precautions

• Since the monitor is heavy, consult your dealer before installation.

• Installing or moving the monitor must be done by two or more people.

• A stand and mounting bracket compliant with VESA specifications is required. Do not use any screw holes other than VESA holes for installation.

• When moving the monitor, be sure to hold it with the handles both on the rear and the unit bottom. Do not hold the LCD panel. This may cause product damage, failure, or injury.

• Install the monitor with the surface perpendicular to a level surface. If necessary, limit the tilt between 0 and 20 degrees downward.

• Mounting the monitor on the wall requires special expertise and the work must be performed by an authorized SHARP dealer. You should never attempt to perform any of this work yourself. Our company will bear no responsibility for accidents or injuries caused by improper mounting or mishandling.

• This monitor should be used at an ambient temperature between 32 °F (0 °C) and 104 °F (40 °C). Provide enough space around the monitor to prevent heat from accumulating inside.

Set the RS-232C communication settings on the PC to match the monitor’s communication settings as follows:

Baud rate 9,600bps Data length 8bits Parity bit None Stop bit 1bit Flow control None

Unit: inch [cm]

*The monitor can be installed close to a wall, etc.

However, the monitor emits heat during operation. Be aware that heat emitted from the monitor may discolour or alter the wall.

If it is difficult to provide such space because the monitor is installed inside a housing or for other reasons, take other measures to keep the ambient temperature between 32°F (0 °C) and 104 °F (40 °C) such as installing a fan in the housing.

• Adhere to the following when installing the monitor in the vertical

orientation. Failing to adhere to the following may cause malfunctions.

Install the monitor such that the power LED is located on the downside.

Set the MONITOR on the SETUP menu to PORTRAIT.

• Do not block any ventilation openings. If the temperature inside the

monitor rises, this could lead to a malfunction.

• After mounting, it is recommended to take some measures to pre-

vent the monitor from falling down.

• Do not place the monitor on a device which generates heat.

• Be sure to use a stand or a wall-mount/ceiling-mount bracket

designed or designated for mounting the monitor.

Return code (0DH, 0AH)

ECDKOL

Advanced operation

This section explains commands for daisy chain connection. The basic communication procedure is the same as in the “One-to-one connection with a PC” section.

You can assign a unique ID number to each monitor. This allows you to control a particular monitor in a daisy chain of monitors. You can assign ID numbers either from the menu screen (using the remote control) or from the PC using RS-232C cable.

[Example]

ID number: 1

ID number: 2 ID number: 3 ID number: 4

If monitors are connected as shown above, you can execute commands like “Set the volume of the monitor with ID 4 to 20”.

When controlling monitors linked in a daisy chain by designating ID numbers, you should basically avoid any duplication of ID numbers.

PN-525U CONNECTION, ADJUSTMENT, OPERATION, AND FUNCTION

2 – 10

ID numbers do not have to be assigned in ascending order starting from the PC. They can also be connected as shown below.

[Example]

ID number: 3 ID number: 2 ID number: 4 ID number: 1

The command examples shown on this page assume the following connection and ID number set up.

ID number: 1 ID number: 2 ID number: 3 ID number: 4

IDST: A monitor receiving this command sets its own ID number in the

parameter field.

Example: IDST0001

OK 001

The ID number of this monitor is set to 1.

Note: You can automatically assign ID numbers by using the IDST

command with the Repeater control. For example, using the command “IDST001

+” automatically sets

the ID numbers, as shown below.

[Example]

ID number: 1 ID number: 2 ID number: 3 ID number: 4

IDST001

ID setting command with repeater control

WAIT

OK 001

OK 002

OK 003 OK 004

“OK” response from ID number : 1

“OK” response from ID number : 2

“OK” response from ID number : 3

“OK” response from ID number : 4 (End)

IDSL: The parameter of this command sets the ID number of the monitor.

The monitor is subject to the next command.

Example:

IDSL0002 WAIT OK 002 VOLM0030 WAIT OK 002 VOLM0020 OK 001

The next command is for the monitor with ID number : 2.

Searching for monitor with ID number : 2

Found monitor with ID number : 2

Sets volume of monitor with ID number : 2 to 30.

Processing

OK response from monitor with ID number : 2

Sets volume to 20.

The volume of the monitor with ID number : 1 (the one directly connected to the PC) is set to 20.

*The IDSL command is effective only once, for the immediately

succeeding command.

IDSL: The parameter of this command sets the ID number of the monitor.

The monitor is subject to all subsequent commands.

Example:

IDLK0002

Following commands are for the monitor with ID number : 2.

WAIT OK 002 VOLM0030

WAIT

Searching for monitor with ID number : 2

Found monitor with ID number : 2

Sets volume of monitor with ID number : 2 to 30.

Processing

OK 002 VOLM0020

Sets volume of monitor with ID number : 2 to 20.

WAIT OK 002

IDLK0000 WAIT OK 002

Canceling fixed ID number setting

Canceling IDLK

Cancelation complete

VOLM0010

OK 001

The volume of the monitor with ID number: 1 (the one directly connected to the PC) is set to 10. (IDLK is canceled.)

*The IDLK command remains effective until it is canceled, or power

is shut off.

IDCK: Provides screen display of the ID number currently assigned to a

monitor, and the ID number currently set for IDLK (if any).

Example:

(After executing IDLK0002)

IDCK0000 ID:001 IDLK:002

(Parameter has no meaning.)

Returned response. The ID number is also displayed on the monitor screen.

IDCK000

Repeater control (If a command is used with repeater control, ID

designation using IDSL or IDLK is canceled.) WAIT ID:001 IDLK:000 ID:002 IDLK:000 ID:003 IDLK:000 ID:004 IDLK:000

This system has a function to allow setting of multiple monitors connected in a daisy chain using a single command. This function is called repeater control. You can use Repeater control function without assigning ID numbers.

[Example]

Set 1 Set 2 Set 3 Set 4

If monitors are connected as shown above, you can execute a command like “Set all monitors’ input settings to PC1 DIGITAL”.

PN-525U CONNECTION, ADJUSTMENT, OPERATION, AND FUNCTION

2 – 11

Repeater control is achieved by setting the FOURTH CHARACTER of the parameter to “

+”.

Example:

VOLM030

+ 1 Sets volume of all monitors to 30.

In repeater control, responses are returned by all the connected monitors. If you want to determine that a value has been returned by a specific set, assign ID numbers to each monitor in advance. When some monitors do not return their responses, the probable cause is that the monitors could not receive the command or command processing is not complete. Do not send a new command.

Example:

(When 4 monitors are connected, and assigned ID numbers: 1 through 4)

VOLM030

WAIT OK 001 OK 002 OK 003

OK 004

If 4 monitors are connected in a chain, reliable operation can be ensured by sending a new command only after a reply has been returned by 4th (last) monitor.

Repeater control can also be used for reading settings.

Example:

VOLM??? + WAIT 10 001 20 002 30 003

Volume settings for all monitors are returned.

30 004

Note:

• If repeater control is used during ID designation (IDSL, IDLK), the ID designation is canceled.

• Commands that use parameters consisting of more than four characters can not be controlled by repeater control.

• After OK or ERR is returned, you must send the following commands. To set a timeout for the command response, specify 10 seconds or longer.

• Provide an interval of 100 ms or more between the command response and the transmission of the next command.
