Using the Screen As a Viewport
The terminal screen shows 16 lines by 20 characters of data at one time. In terminal
emulation (TE) or custom applications, the terminal’s screen may show only part of each
25 line by 80 character screen that appears on a full-size terminal. You can use the
terminal screen as a viewport to move around and see the entire 25 x 80 screen.
The viewport lets you view screens and enter data by showing the part of the screen you
are using. When you are using one of the Intermec TE applications, the viewport
automatically moves to the cursor when there is data entry from the host computer or the
terminal. You can configure the viewport for your TE applications to:
• Follow the cursor
• Center the viewport around the cursor
For help on configuring the TE viewport options, see the TRAKKER Antares Terminal
Emulation User’s Guide.
The first time you turn the terminal on, it displays the upper left corner of a full-size
terminal screen. This is the viewport’s home position. A screen or application that
displays more than 16 lines by 20 characters of data at one time has data in the unseen
area of the screen. When you move the cursor or viewport out of the home position
(upper left corner), the Viewport icon displays until the viewport is returned to its home
position.

Adjusting the Screen From the Keypad
The Backlight key is one of the special features built into the terminal’s keypad. You
can use the Backlight key to:
• Turn the backlight on and off on the terminal’s screen.
• Adjust the display contrast.
• Change the beep volume of the terminal’s audio signals.
For a detailed description of the backlight, contrast, and beep volume commands, see
Chapter 9, “Configuration Command Reference.”
Note: The Backlight key temporarily changes the backlight, contrast, or beep volume.
These changes are not saved permanently in flash memory.
