Handling
This chapter explains the basic handling methods for this product.
Turning the Power On/Off
The power for this product is supplied by USB bus power, which means that the power is supplied from the connected printer or computer through the USB connector.
To turn this product on or off, turn the connected printer or computer on or off.
The display may not turn off while the power is still supplied to USB connector, even if the printer's
Power LED is off.
Changing the Angle of the Display Unit
You can change the angle of the display unit by holding the stand with your hand while moving the display unit.
The following shows the range of motion.
Do not exceed the range of motion when moving the display unit. Applying excess force when
moving the display unit may cause damage.

Cleaning the Outer Case
Be sure to disconnect the USB cable from the printer or the computer, and then wipe the dirt off the outer case
with a dry cloth or a damp cloth.
• Never clean the product with alcohol, benzine, thinner, or other such solvents. Doing so may
damage or break the parts made of plastic and rubber.
• Rubbing the LCD screen with too much force using a dry cloth may scratch the surface.

Chapter 4 Application Development Information
Application Development Information
This chapter explains how to control the customer display as well as necessary information for developing system applications using this product.
Controlling the Customer display
This product supports the following control commands.
• ePOS-Print XML (Only when connected to a TM printer that supports ePOS-Print)
• ESC/POS
Users can control the customer display by using the aforementioned commands, or the following development
kits or drivers.
• Epson ePOS SDK
• EPSON OPOS ADK
• EPSON OPOS ADK for .NET
• EPSON JavaPOS ADK
• EPSON Advanced Printer Driver Ver.5 (APD5)
ePOS-Print XML
ePOS-Print XML is the Epson original control command system for POS printers and customer displays.
By sending an XML-format request message via HTTP transmission to a TM printer that supports ePOS-Print,
you can control the customer display connected to the printer. For details about ePOS-Print XML, see the
ePOS-Print XML User's Manual.
Control via ePOS-Print XML is possible only when connected to a TM printer that supports ePOSPrint.
For the supported printers, see
"Connectable TM Printers" on page 9.
ESC/POS
ESC/POS is the Epson original printer command system for POS printers and customer display. With ESC/POS
commands, you can directly control all the this product functions, but detailed knowledge of printer specifications or combination of commands is required, compared to using drivers and applications.
For details on the ESC/POS commands, see "ESC/POS Command Reference for Customer Displays" by accessing the URL below.

Cautionary Notes on Marquee Display
Due to the nature of the LCD installed, the marquee display (horizontal scroll display) may become difficult to
see when the characters displayed are switched at a short interval.
We recommend using the following method to set the character display switch interval to 600 msec or longer.
• ePOS SDK
Perform settings using the unitWait parameter of addMarguee (for JavaScript) or addMarqueeText (for the others).
For details, see the User's Manual included with SDK.
• ESC/POS Commands
Perform settings using the parameter n of the command US ^.
For details, see "ESC/POS Command Reference for Customer Displays."
• OPOS ADK
Perform settings using the MarqueeUnitWait property.
For details, see the Application Development Guide included with ADK.
