ScanVue420 Vacuum Fluorescent Display
Note: references in this manual to the use of graphics images, double-byte text and
downloaded fonts are not applicable to the Scanvue420 model.
Description
ScanVue420 has a 4 line x 20 character x 5mm high, 5x7 dot matrix vacuum fluorescent
(VF) display and shows text in a fixed font size and pitch. The default character set is
US-ASCII extended with 64 European characters. There are three (3) more 64 character
extended language sets Cyrillic, Hebrew and Katakana that can be selected from the
UnitConfig program by entering the character set name in the mode ExtCharacterSet.
This feature allows the end user to set the character set to the language of choice.
Once ScanVue420 is set to display one of these optional character sets, any message
sent to the display will use the characters in that chosen language set. The language
character sets are shown in Appendix D and always contains the US-ASCII characters
shown in Table 4 plus one of the optional 64 character sets shown in Tables 5-8.
The user may change any or all of the 3 internal customer messages (factory default is
English) into one of the 4 language character sets available on the VF display. This will
allow the user to display customer messages in the language of the country the unit is
installed in.
As this model cannot show graphics or inherently run a slideshow, the customer greeting
screen shown in Figure 15 is normally displayed as a static screen. It is possible to
create a loop of linked text messages on the server side that can be sent to ScanVue420
in a timed sequence to create a ‘text slideshow’.
Operation
When ScanVue420 finishes booting up it will display the info status screens first, then
the logo screen and finally the static greeting screen shown in Figure 15. This screen
will be continuously displayed until either an item is scanned or the host server sends a
different message.

sends the ASCII characters to
the server using the protocols described in Chapter 4 and 5. The mode SendUnitID will
transmit the units ID as well as the ASCII characters when set TRUE (default). If the VF
unit is mixed with LCD units in the same installation, it is important to keep this mode set
