CONNECTION, ADJUSTMENT, OPERATION, AND FUNCTION

2 – 3

You can control this monitor from a PC via RS-232C (COM port) on the
PC. You can also connect multiple monitors via a daisy chain by using a
PC. By assigning ID numbers to each monitor, you can make input
mode selection/adjustment or can check the status of a specific monitor.

■ PC connection

Connect with RS-232C straight cable between the PC’s COM port
(RS-232C connector) and the RS-232C input terminal on the rear of the
monitor.

Connect with RS-232C straight cable between the PC’s COM port
(RS-232C connector) and the RS-232C input terminal on the rear of the

first monitor.

Next, connect RS-232C straight cable to the first monitor’s RS-232C
output terminal and to the second monitor’s RS-232C input terminal.

Connect in the same way to the third and subsequent monitors.

Up to 25 monitors can be connected. (Depending on the length of the
cable used and the surrounding environment.) 

■ Communication conditions

Set the RS-232C communication settings on the PC to match the

monitor’s communication settings as follows:

■ Mounting precautions

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

• When installing or moving the monitor, ensure that this is carried out

by at least 2 people.

•  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 0°C

and 40°C. Provide enough space around the monitor to prevent heat

from accumulating inside.

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 0°C and 40°C such as

installing a fan in the housing.

•  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. Secure the monitor by fastening

the hooks at the top of the monitor to a wall or a pillar with strong

cord and brackets (not included).

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

•  This monitor is fixed to the temporary stand when shipped from the

factory. Please note that this stand is for temporary use only until

the monitor is properly mounted.

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

designed or designated for mounting the monitor.

•  This monitor is designed to be installed on a concrete wall or pillar.

Reinforced work might be necessary for some materials such as

plaster / thin plastic board / wood before starting installation.

This monitor and bracket must be installed on a wall which can

endure at least 4 times or more the weight of the monitor. Install by

the most suitable method for the material and the structure.
