Introduction
INTRODUCTION
Thank you for choosing the WPD-220VF Pole Display. The WPD-220VF
provides both reliability and performance in a professional looking design.In this
guide, you will find connection and configuration information to help you connect
the display to your computer.
The WPD-220VF pole display uses a vacuum fluorescent display (VFD) tube
presenting bright and easy to read characters. Because of the VFD technology
the display is viewable from a wide angle. Users will appreciate not having to
remain in a fixed viewing position to see the display; they will be free to move
forward in line and still keep the display readable.The WPD-220VF pole display
has 2 pole sections giving you the choice of 4 different display heights. The
display can be rotated up to 270°.The head of the display can be tilted up to
35°.The combination of these features gives you flexibility to tailor the display
position to your unique application.
The WPD-220VF pole display uses an easy to connect RS-232C serial port
connection with a wide range of available communication speeds from 300 to
38,400bps.
