CDD-562L/564 Demodulator with IP Module Revision 1
Introduction MN/CDD564L.IOM

1.3.6 Data Interfaces
The demodulators include, as standard, a 10/100 BaseT Ethernet Interface.
1.3.7 Flash Upgrading Demodulator Firmware
The demodulators use ‘flash memory’ technology internally, and new firmware can be uploaded
to the unit from an external PC. This simplifies software upgrading, and updates can be sent via
the Internet (from Comtech EF Data’s Web server), e-mail, or on CD. The upgrade can be
performed without opening the unit, by simply connecting the unit to a 10/100BaseT Ethernet
port, then FTPing the download via a PC.
See Chapter 4. FLASH UPGRADING for further information.
1.3.8 Fully Accessible System Topology (FAST)
The demodulators are extremely flexible and powerful, and incorporate a large number of optional
features. In order to permit a lower initial cost, the demodulator 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 loaded into the unit, entered remotely via the remote
port located on the demodulator rear panel.
These unique access codes may be purchased at any time from Comtech EF Data.
FAST System Theory
FAST facilitates on-location upgrade of the operating feature set without removing a
demodulator 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.
When service requirements change, the operator can upgrade the topology of the demodulator to meet
those requirements within minutes. This accelerated upgrade can be accomplished because of FAST’s
extensive use of the programmable logic devices incorporated into Comtech EF Data products.
FAST Implementation
Comtech EF Data’s FAST system is factory-implemented in the demodulator. All FAST options are
available through the basic platform unit at the time of order – FAST allows immediate activation of
available options, after confirmation by Comtech EF Data, via the remote control interface.
See Appendix C. FAST ACTIVATION PROCEDURE for further information.
FAST Accessible Options
Hardware options for basic demodulators can be ordered and installed either at the factory or in
the field. The operator can select options that can be activated easily in the field, depending on
the current hardware configuration of the demodulator. A unique access code enables
configuration of the available hardware.
