In scanvue.ini, double byte strings can be used for wallpaper but the text must start with

<< instead of < or // instead of /.

For the Demoserve data file (data.dat) on the CD-ROM, the characters |> indicate a Big-

Endian string and |< indicates a Little-Endian string. Note: Demoserve actually sends

the FE FF or FF FE bytes not |> or |<.

A utility program, dmp2gdf, provided on the CD-ROM creates a .gdf (double-byte) font

file from a single byte ASCII font file.

Using Input Devices

Scanvue5 has four optional types of manual input device in addition to the standard

barcode scanner. Each type of manual input device generates message tokens with a

similar message packet structure called EVENTS and thus they are all treated together

in this section.

Activating any of the input devices—barcode scanner, touch screen, keypad, magnetic

stripe reader or push button, causes Scanvue5 to transmit the input data, usually a string

of alphanumeric characters, to the host computer for further action by the server based

application.

Touch Screen

The digital touch panel is organized in a 16 column x 12 row matrix. The LCD screen

resolution is 320 x 240 pixels (¼ VGA). Thus each of the 192 discrete touch areas

formed by the matrix is a 20 x 20 pixel square, which is dimensionally ¼”x ¼” and

defines the maximum resolution of the touch screen. Resolution scaling (increasing the

dimensional size of the discrete touch areas) may be set for each axis independently

down to 1 column x 1 row—in other words where the whole display screen is a single

touch button. Resolution scaling can also be changed dynamically by the users

application. In fact, the internal resolution is changed to be 2:1 for increased sensitivity.

reported position={measured position x vertical (or horiz.) scale}/max. resolution

rounded to the next highest integer.

Factory default setting is at the touch screens highest resolution of 31 x 23 where the top

left corner co-ordinate is y,x = 0,0 and the bottom right corner co-ordinate y,x = 23,31.

Examples of calculations for a 4 x 4 matrix—although this is done internally and the user

will only see the reported position.
