Spectrum24 Terminals

Spectrum24 terminals use standard communications protocols to accomplish wireless
connectivity. These protocols are generalized and take up considerably more space in the
terminal's NVM. With less space available in NVM for application files, Spectum24
terminals operate as diskless computing workstations. The terminal's NVM contains
system files required to connect to and download the application files from a network server
and to provide network diagnostics and configuration. The application files are downloaded
each time the terminal is booted.

Optional Flash Disk

Spectrum24 terminals can optionally contain an additional megabyte of non-volatile
memory or flash. This extra memory reduces the time and resources required to load
applications into the terminal and offers the ability to run multiple applications from the
same terminal.
The flash disk is accessed via a driver, FLASHDSK.SYS, which makes the flash disk
appear to a program as another disk drive (E:). The drive reads data quickly but writes
slowly (e.g., for even the smallest files, the write process takes 3-4 seconds).
If your Spectrum24 terminal includes a flash disk, you may set the IP address and
download software not available on standard Spectrum24 terminals. For more information,
refer to the Spectrum24 Flash Disk Addendum.
