Flash Upgrading
The internal firmware is both powerful and flexible, permitting storage and retrieval of up to 10
different configurations. The unit uses 'flash memory' technology internally, and new firmware
can be uploaded to the unit from an external PC. This simplifies software upgrading, and updates
are deliverable over satellite, via the Internet (using the CDD-880 Web Server (HTTP) Interface),
e-mail, or on CD. The upgrade can be performed without opening the unit, by simply connecting
the CDD-880 to the Ethernet port of a computer. See Chapter 4. FLASH UPGRADING for
further information.

Fully Accessible System Topology (FAST)
The CDD-880 is extremely flexible and powerful, and incorporates a large number of optional
features. In order to permit a lower initial cost, The CDD-880 may be purchased with only the
desired features enabled.
If, at a later date, a user wishes to upgrade the functionality of a demodulator, Comtech EF Data
provides Fully Accessible System Topology (FAST), which permits the purchase and installation
of options through special authorization codes entered into the unit using the CDD-880 Web Server
(HTTP) Interface.
These unique access codes may be purchased during normal business hours from Comtech EF
Data.
FAST System Theory
FAST facilitates on-location upgrade of the operating feature set without removing a CDD-880
from the setup.
With FAST technology, operators have maximum flexibility for enabling functions as they are
required. FAST allows an operator to order a demodulator precisely tailored for the initial
application.
