Rev. 1 1–3

Introduction CST-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.

1–4 Rev. 1

CST-5005 C-Band Satellite Terminal Introduction

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

Rev. 1 2–9

Single Thread System Installation CST-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.

3. Install the 20” unistruts as follows:

Note:

The placement of the pipe blocks may interfere with the inner or center unistrut attaching bolts. Be sure to determine the pipe block placement locations before bolting the 20” unistruts in place. It may be necessary to eliminate the center or inner 20” unistrut mounting spring nuts and bolts.

a. Insert a spring nut between

the unistrut mounting bolts on both RFTs, as illustrated.

b. To install each spring nut:

(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.

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.

CST-5005 C-Band Satellite Terminal Theory 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 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.

6.2 Fault Isolation

Once the terminal has been set up for operation, troubleshooting faults can be accomplished by monitoring the terminal faults remotely, via the optional KP-10 external keypad, or by removing the cover and observing the LEDs on the M&C board.

The following table should be used in isolating a problem and deciding the appropriate action to be taken.

Refer to Figures 6-1 and 6-2 for the locations of the various modules mentioned in this list.

Fault Possible Problem and Action

+5 VOLT +5V power supply fault. Indicates the +5V power supply on the M&C board is at

a high or a low voltage condition. Allowable level variation is ± 5%. Check for a short on the +5V line, or faulty connection at P4 on the M&C board.

+12 VOLT +12V supply fault. Indicates the +12V power supply is at a high or low voltage

condition. Check for a short on the +12V line, or faulty connections between any of the internal modules.

HPA High Power Amplifier fault. Verify that the RF output is programmed ON. Check

for a loose connection at J3. If acceptable, replace the U/C-HPA module. Once the problem has been corrected, the transmitter must be turned back ON.

OSC Reference Oscillator fault. Check RF cable from reference oscillator module to

synthesizer/IFLO module. Check P4 on M&C and P13 on oscillator module. If acceptable, replace the reference oscillator module.

D/C Down Converter fault. Indicates either faulty connection of module or missing

temperature/frequency compensation. Check P4 (at M&C) and J8 (at U/C). If acceptable, replace D/C module.

U/C Up Converter fault. Indicates either faulty connection of module or missing

temperature/frequency compensation. Check J3 (at M&C) and P12 (at U/C). If acceptable, replace U/C-HPA module.

SYNTH Synthesizer fault. Indicates that the synthesizer if out of lock. Check the RF

cable from reference oscillator module to the synthesizer/IFLO module. Check J9, J8, and P7. If acceptable, replace the synthesizer/IFLO module.

IFLO IF Local Oscillator fault. Indicates the IFLO is out of lock. Check the connection

of the RF cable from reference oscillator module, J9, J8, and P7. If acceptable, replace the synthesizer/IFLO module.

LNA Low Noise Amplifier fault. Check the RF cable from the LNA to J4 of the

RFT-505 terminal. If acceptable, replace the LNA.

Appendix A.

REMOTE CONTROL OPERATION

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. 1 A–1

Remote Control Operation CST-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–2 Rev. 1

CST-5005 C-Band Satellite Terminal Remote 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.

Rev. 1 A–3

Remote Control Operation CST-5005 C-Band Satellite Terminal

A.2.4 End Character

Each message is ended with a single character which sig n als the end of the m essag e:

“cr”

•

“]”

•

Note:

For the external keypad (i.e., the KP10), the end of message character is:

Carriage return character for commands End bracket for responses

• “cr]” Carriage return and end bracket for commands

• “]” End bracket for responses
