direct connect download of a label format (label formats can also be stored
and recalled from RAM modules) or graphics (logos).
Graphics can be loaded
using programs with an image download function. The loading of images
can also be done with minimal programming on most host computers. Single
font bitmaps, images, or formats cannot be deleted individually. The entire
module must be cleared and data reloaded. This module can be installed in
either slot A or B. This is a volatile memory (temporary storage) and will be
lost at power down.
256K Flash ROM Module: This module provides the same features as the
RAM modules with the added benefit of permanent storage. Typical
applications for a Flash module include downloadable soft fonts, graphics,
and label format storage for use with host computers. This module must be
installed in slot A when being loaded with data. Once it is programmed they
can be installed in either slot A or B. There is a copy command available for
duplicating ROM modules. When using this feature, the source module
should be installed in the B slot, and the blank module in the A slot. A
WRITE PROTECT switch on the Flash module can protect data stored on the
module from being overwritten or erased. This module is a non-volatile
memory, data is stored permanently.
512K RAM Module: This module is used primarily when label formats
exceed 10 inches in length. When this module is in the A slot, the dot memory
is double (from 10” to 20” at 203 dpi). The upper half of memory is reserved
for long label length formatting and the bottom half functions the same as the
256K RAM module. This is a volatile memory (temporary storage) and will be
lost at power down.
Optional Font Modules
There are six optional 512K byte ROM FONT modules available. They are:
1. CG Triumvirate Bold
2. CG Triumvirate Italic
3. CG Times
4. CG Times Bold
5. Futura Extra Bold Condensed
6. Plantin
Each ROM Font module comes with documentation detailing the type and
sizes available on the module and the font number of each size used in the
label formatting. ROM Font modules are programmed at the factory and
cannot be modified for any other purpose. ROM Font modules will operate in
either the A or the B slot.
