IntroductionCST-5005 C-Band Satellite Terminal
1.1.1 Applications
When used in conjunction with Comtech EFData modems, the CST-5005 is ideal for:
•Single digit carriers up to 2.048 Mbit/s
•Multiple carrier operation over a 36 MHz bandwidth
Because the CST-5005 has a 70 MHz IF, it can also be used for other analog and digital
applications.
Small-to-medium size earth stations are easily constructed and commissioned with the
CST-5005.
When used with a high-gain antenna, the CST-5005 can also be used as the Radio
Frequency (RF) electronics of a central hub in point-to-multipoint applications, as well
as serve as the terminal for the end points of the network.
1.1.2 Monitor and Control
An on-board microcomputer monitors and controls all operational parameters and system
status of the CST-5005. This powerful M&C system enables the user to locally or
remotely control functions such as:
Output power
•
Transmit/receive channel frequencies
•
The system also reports terminal configuration status, as well as fault status of all
CST-5005 components.
The CST-5005 can be initially configured using a connection of a common
ASCII/RS-232-C terminal connected to the serial port.
A simple command set allows total configuration control and retrieval of status
information.
If the indoor unit is a more sophisticated station M&C computer, the serial port can be
set to RS-485 for bus operation.
For more information on the M&C board, refer to Chapter 5.
1–4Rev. 1
CST-5005 C-Band Satellite TerminalIntroduction
1.1.3 Low Noise Amplifier (LNA)
The feed assembly consists of an LNA and a wave guide transmit reject filter.
The transmit reject filter provides receive system protection from transmit energy fed
back through the antenna feed system.
The LNA standard noise temperature is 65°K, with optional upgrades down to 33°K,
depending upon gain over temperature (G/T) requirements.
1.1.4 Outdoor Enclosure
The RFT-505 is a weatherproof enclosure housing the following:
Solid State Power Amplifier (SSPA)
•
Up and down converters
•
M&C microprocessor
•
Power supply and cables which interface with an antenna subsystem
•
In the transmit (uplink) direction, the RFT-505 accepts a 70 MHz IF signal, and transmits
it in the 5.845 to 6.425 GHz frequency band.
In the receive (downlink) direction, the terminal accepts an RF signal in the 3.620 to
4.200 GHz band, and converts the signal to 70 MHz IF output.
Power levels range from +8 dBm (for driving an external TWT) to 10W, depending upon
Equivalent Isotropically Radiated Power (EIRP) requirements.
The up and down converters are dual conversion, with individual synthesizers for
independent transmit and receive transponder selection.
The microprocessor provides:
•Online loop monitoring
•Dynamic control functions
•Configuration control
•Fault/status monitoring
•Serial computer/terminal interface

2.3 RFT Installation
At the customer’s discretion, the RFT can be installed anywhere on or near the antenna.
The supplied hardware allows the installer a wide range of installation alternatives,
including:
•Vertical pole (e.g., mast) (either square or round). This is the most typical
installation.
•Within the hub of a large antenna.
•Spar (i.e., square bar) on the antenna structure.
EFData recommends that the RFT be mounted vertically, with the connections facing the
ground.

2.3.2.1 Round Pole
Note:
The following process is for a typical installation. Custom systems may be
ordered, and are beyond the scope of this manual.
To install the RFT to a round vertical pole:
1. Set the unit on its side, with the mounting holes facing up.
2. Install the two 14” unistruts as follows:
a.Position a 14” unistrut (with
the open side facing up)
over one set of the mounting
holes on the RFT.
b. Using four 1/4-20 bolts,
1/4” split lockwashers, and
1/4” flat washers, attach the
14” unistrut to the RFT.
Tighten the bolts firmly.
c.Repeat Steps 2.a. and 2.b.
for the second 14” unistrut.
Rev. 1 2–9
Single Thread System InstallationCST-5005 C-Band Satellite Terminal
3. Install the pipe blocks as follows:
a. Install two spring nuts in each of four 14” unistruts (the two just mounted on
the RFT, and two additional).
Be sure to position the spring nuts in the unistruts wide enough apart so that
when the pipe blocks are installed, they will clear the pole when the unit is
lifted into place for installation.
b. Install each spring nut as follows:
(1) Place the spring nut in the unistrut channel, spring side down, with its
wide side parallel with the unistrut channel.
(2) Press down on the spring nut to compress the spring, and rotate the nut
90° (i.e., perpendicular to the unistrut).
(3) Release pressure on the spring nut.
(4) Repeat Steps 3.b.(1) through 3.b.(3) for each spring nut.
c.Using four 5/16-18 bolts, 5/16” split
lockwashers, and 5/16” flat washers,
loosely secure the pipe blocks to the
spring nuts.
Ensure the pipe blocks are installed
with the long angle facing inward,
toward the pipe, as illustrated.
DO NOT tighten the pipe block bolts
until after mounting the RFT on the
vertical pole. (See Step 5.e.)

THEORY OF OPERATION
This chapter provides the basic theory of operation for the Monitor and Control (M&C)
board, high stability oscillator, IFLO synthesizer, and the up and down converters.
5.1 Monitor and Control
The RFT-505 uses a sophisticated microcontroller module to perform the M&C
functions of the terminal. This board (refer to Figure 5-1) is located inside of the
RFT-505, on top of the other assemblies.
The M&C monitors the RFT-505 and provides configuration updates to other modules
within the terminal when necessary.
Chapter 5.

Terminal configuration parameters are maintained in EEPROM, which provides for total
recovery after a power-down situation.
Fault monitoring and status gathering are also provided.
All RFT-505 functions are accessible through the remote communications interface.
Note:
For more information on the M&C board, refer to Chapter 1.

5–2Rev. 1
CST-5005 C-Band Satellite TerminalTheory of Operation
5.1.1 EEPROM Memory
EEPROM memory on the M&C module allows it to retain configuration information
without prime power for at least one year. If the terminal has been powered down, the
following power-up sequence will be carried out by the M&C microcontroller when
power is reapplied:
1. The microcontroller checks the EEPROM’s Random Access Memory (RAM) to
see if valid data has been retained. If valid data has been retained, the terminal is
reconfigured to the configuration maintained in EEPROM.
2. If EEPROM memory fails the valid data test, a default configuration from Read
Only Memory (ROM) is loaded into the system.
5.1.2 Remote Interface
The functions of the RFT-505 can be remotely controlled and monitored via an RS-485
or RS 232-C communications link. The M&C module must be hardware configured to
one of the two interfaces.
The RS-485 interface makes it possible to operate 255 terminals on a common
communications link.
The RS-232-C interface is used to communicate with a single terminal.

5.1.4 Theory of Operation
Refer to Figure 5-3 for a functional block diagram of the M&C.
The M&C board performs the following operations:
•Receives the desired frequency from either the remote RS-232-C/485 or KP-10
keypad, and after converting it to a synthesizer setting, stores it to the applicable
synthesizer output latch.
•Reads the thermistors located in the up converter, down converter, and highpower amplifier, and converts them to temperatures for display.
•Reads the characterization EEPROMs in the up converter, down converter, and
high-power amplifier, and calculates an Automatic Gain Control (AGC) voltage
based on frequency and temperature to linearize the respective module.
•Receives fault inputs from all modules, and presents them to the remote
RS-232-C/485 and the optional KP-10 keypad display.
•Performs an initial current sense on the LNA, and stores the reading in
EEPROM. Subsequent current sense readings are taken and compared to the
initial reading to determine a fault.

5.5.2 Theory of Operation
The RFT-505 down converter utilizes a dual conversion process to convert from an input
RF frequency band of 3620 to 4200 MHz, to an output baseband 70 MHz IF signal.
The first conversion requires a down converter synthesizer frequency input to mix with
the RF input.
The M&C board controls the frequency selection of the synthesizer.
The synthesizer output frequency band is from 4662.5 to 5242.5 MHz, in 125 kHz steps.
The output of the first mixing process is at a frequency of 1042.5 MHz. The 1042.5 MHz
output is applied to the second mixer, which mixes with an IF Local Oscillator frequency
input at 1112.5 MHz.
The output of the second mixer is the desired baseband 70 MHz IF signal.
The M&C board interpolates the factory preset compensation data that is stored in an
EEPROM inside the down converter. This data allows the M&C board to command and
compensate the down converter’s output power, ensuring proper output power levels
over the entire frequency and temperature range.

The M&C board also supplies the DC power for the LNA, which is subsequently
injected into the RF input connector.
5.6 Up Converter
The function of the up converter is to convert the 70 MHz IF signal from the indoor unit
modem to a C-band signal to be transmitted.

5.6.2 Theory of Operation
The RFT-505 up converter utilizes a dual conversion process to convert from a baseband
70 MHz IF signal to the output RF frequency band. The first conversion requires an IF
Local Oscillator frequency input at 1112.5 MHz from the synthesizer module.
The output of the first mixing process is at a frequency of 1182.5 MHz. The 1182.5 MHz
output is applied to the second mixer which mixes with the synthesizer frequency input.
The M&C board controls the frequency selection of the synthesizer and the U/C
attenuator.
The M&C board also interpolates the factory preset compensation data that is stored in
an EEPROM inside the up converter. This data allows the M&C board to command and
compensate the up converter’s output power, ensuring proper output power levels over
the entire frequency and temperature range.
The up converter synthesizer output frequency band is from 4662.5 to 5242.5 MHz, in
125 kHz steps.
The output of the second mixer is the desired RF frequency band of 5845 to 6425 MHz.

REMOTE CONTROL OPERATION
A
This appendix describes the remote control operation of the RFT-505.
•Firmware number:FW/4644-1
•Software version:1.0
A.1 General
Remote controls and status information are transferred via an RS- 485 (optional RS- 232-C)
serial communications link.
Commands and data are transferred on the remote control com munications link as
US ASCII-encoded character strings.
The remote communications link is operated in a half- duplex m ode.
Communications on the rem ote link are initiated by a rem o te controller or term inal. The
RFT-505 never transmits data on the link unless it is com manded to do so.
Rev. 1A–1
Remote Control OperationCST-5005 C-Band Satellite Terminal
A.2 Message Structure
The ASCII character form at used requires 11 bits/character:
•1 start bit
•7 information bits
•1 parity bit
•2 stop bits
or:
•1 start bit
•8 information bits
•no parity bit
•2 stop bits
Messages on the remote link fall into the categories of commands and responses.
Commands are m essag es w hich are transm itted to an R FT- 505, w hile responses are
messages returned by an RFT-505 in response to a command.
The general message structure is as follows:
•Start Character
•Device Address
•Command/Response
•End of Message Character
A.2.1 Start Character
A single character precedes all messages transmitted on the remote link. This character
flags the start of a message. This character is:
“<”
•
“>”
•
for commands
for responses
A–2Rev. 1
CST-5005 C-Band Satellite TerminalRemote Control Operation
A.2.2 Device Address
The device address is the address of the controller which is designated to receive a
transmitted command, or w hich is responding to a com m and.
Valid device addresses are 1 to 3 characters long, and in the range of 1 to 255. Address 0 is
reserved as a global address which simultaneously addresses all dev ices on a g iv en
communications link. Devices do not acknowledge global commands.
Each RFT-505 which is connected to a common rem ote communications link must be
assigned its own unique address. Addresses are software selectable and must be in the
range of 1 to 255.
Note:
Global address “*” is reserved for the external keypad (i.e., the KP-10).
A.2.3 Command/Response
The command/response portion of the messag e contains a v ariable leng th character
sequence which conveys command and response data.
If a satellite modem receiv es a message addressed to it which does not match the
established protocol or cannot be implemented, a negativ e acknowledg ment message is sent
in response. This message is:
add/?ER1_parity error'cr''lf']
•>
(Error message for EV, OD, or NO parity errors.)
>add/?ER2_invalid parameter'cr''lf']
•
(Error message for a recognized command which cannot be implemented or has parameters
which are out of range.)
add/?ER3_unrecognizable command'cr''lf']
•>
(Error message for unrecognizable command or bad command syntax.)
>add/?ER4_converter in local mode'cr''lf ']
•
(Controller in lock mode. Must go to enable mode first.)
>add/?ER5_not supported by hardware'cr''lf']
•
(Command is a valid command. However, it is not supported by the current hardware
configuration.)
Note:
“add” is used to indicate a valid 1 to 3 character device address in the
range between 1 and 255.

Where: xxx = ON (the default, enable monitor) or OFF.
Where: nnn = DAC set ting from 0 to 255.
Where: nnn = Current DAC s etting.
Where: xx = LK (lock) or EN (enable) (the def aul t).
Lock mode prevents the c urrent settings from being changed.

Allows the user to select any one of three 'PreSet'
configurations. The users must first program (store) a
configuration using the PGM_n command defined below. This
command used without the P reset number (n) will provide the
current programming of each of the three Presets.
Where: xxxxx = INDEP (the de faul t) or DEP.
Note: For use in redundant system only with RSU-503 switch.
(INDEP TX and RX switch independently on fault to backup
terminal. DEP switches both TX and RX on fault to backup
terminal.)
