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 por t
connection with a wide range of available communication speeds from 300 to
38,400bps.

Specifications

Serial port (RS232C)

Serial port (RS232C) communication

(a) This interface specification is based on EIA RS232C baud rate 300 to 38400

BPS, 8 data bits, none parity, 1 or more stop bits

(b) Serial port (RS232C) communication data link

Data link flow chart:

PC/HOST display display printer printer PC/HOST

Control for RTS and DTR :

PC/HOST display display printer printer PC/HOST

(c) The device will activate DTR or RTS signal to PC/host in the following two

conditions:

1. Printer will activate DTR or RTS signal.

2.The pass through buffer is full ( 200 bytes ) .
* If PC/host keeps transmitting the data to printer when CD3220 activate

DTR or RTS, the data will be lost.

Serial port interface to the space-saving base portion

(c) RS232C interface to PC/HOST cable, PC/HOST side

connector pin assignment

Connector type: D-sub 9 pin (Male)

Pin No. Signal Direction Function description

2 TXD From printer to PC/Host Printer status data
3 RXD Input Receive data
