MultiByte International Characters
Most languages use a single byte of 8 bits to represent a character, e.g. English,
French, German, Hebrew, Russian, Thai, etc.
Multibyte character fonts require more than the usual 8 bits to specify a character.
This occurs when a language has more than 256 characters (2
8
) in a font. For
example, Chinese fonts contain several thousand characters. Other multibyte
languages include Japanese and Korean.
There are two separate issues with multibyte characters - static text on buttons and
indirect text on buttons.
Static text on a button, entered in the standard way in VT Pro-e, always works under
Windows 98. Under Windows XP, you must use VT Pro-e 3.0 or later.
Indirect text on a button is entered in VT Pro-e and the actual string to be displayed
is entered in SIMPL Windows. You must use VT Pro-e 3.0 or later to guarantee that
the full set of characters in the font is stored on the touchpanel. You must use SIMPL
Windows 2.03.11 or later to enter Chinese characters directly. As of this publication
date, only completely single byte or completely multibyte strings may be entered or
they will not be compiled correctly in SIMPL Windows. In other words, you cannot
enter Chinese character interspersed with numbers. You can enter Chinese characters
or numbers in separate strings.
Of course, you can always use the workaround of showing a graphic that displays the
string, but it is not dynamic.
Uploading and Upgrading
Assuming a PC is properly connected to the entire system, Crestron programming
software allows the programmer to upload programs and projects to the system and
touchpanel after their development. However, there are times when the files for the
program and projects are compiled and not uploaded. Instead, compiled files may be
distributed from programmers to installers, from Crestron to dealers, etc. Even
firmware upgrades are available from the Crestron website as new features are
developed after product releases. In those instances, one has the option to upload via
the programming software or to upload and upgrade via the Crestron Viewport.
NOTE: Currently, the Crestron Viewport is only available as a pull-down command
from SIMPL Windows and VT Pro-e (Tools | Viewport). The Viewport utility
accomplishes multiple system tasks, primarily via an RS-232 or TCP/IP connection
between the control system and a PC. It is used to observe system processes, upload
new operating systems and firmware, change system and network parameters, and
communicate with network device consoles and touchpanels, among many other
tasks. Viewport can also function as a terminal emulator for generic file transfer. All
of these functions are accessed through the commands and options in the Viewport
menus. Therefore, for its effectiveness as a support and diagnostic tool, the Crestron
Viewport may be preferred over development tools when uploading programs and
projects.
The following sections define how one would upload a SIMPL Windows program,
VT Pro-e project or upgrade the firmware of the TPS-2000L touchpanel. However,
before attempting to upload or upgrade, it is necessary to establish communications.
