Appendix B.REDUNDANT SYSTEMS

The CSAT-6070, 5 to 25 Watt C-Band Tranceiver, is capable of operating in both stand-alone and redundant configurations. The CSAT fully redundant system provides automatic detection, switching, and status for both its configuration and health. The system is designed such that stand-alone operation is a functional sub-set of the fully redundant CSAT system. This provides the user with transparent functionality regardless of the mode or complexity the system has been setup to operate in.

Due to the parallel nature of the M&C interface, only EIA-485 and EIA-422

communications are supported through this device.

Installation guidelines regarding power line quality

As a company with many years of experience selling and servicing equipment installed around the world, Comtech EF Data has become familiar with the varying quality of the AC power grid around the world. The following offers some installation guidelines that should help ensure a reliable installation.

• Surge suppression: High voltage surges can cause failure of the power supply. These surges are typically caused by circuit switching on the main AC power grid, erratic generator operation, and also by lightning strikes. While the transceiver does have built in surge suppression, if the unit will be installed in a location with questionable power grid quality, Comtech EF Data recommends installation of additional power conditioning/surge suppression at the power junction box.

• Grounding: The transceiver provides a grounding terminal. This is provided to allow the user to ground the transceiver to the antenna’s grounding network. All components installed at the antenna should be grounded to a common grounding point at the antenna.

• Electrical welding: If welding needs to take place at the antenna, disconnect all cables from the transceiver except for the ground wire. Cap all RF connections with terminations. This will prevent damage to the input/output circuitry of the transceiver.

• Lightning: Lightning strikes on or around the antenna will generate extremely high voltages on all cables connected to the transceiver. Depending on the severity of the strike, the transceivers internal surge protection combined with the recommended external suppression may protect the transceivers power supply. However, if the installation will be in an area with a high probability of lightning strikes, Comtech EF Data recommends the installation of surge suppression on the RF and IF cables. One source of these suppressors is PolyPhaser (

FULL RATED POWER

The CSAT-6070 delivers the full rated power, or more, measured at the 1 dB compression point and at the output flange. The user now knows the useable output power he is purchasing and receives full value for his investment.

PHASE NOISE

The dual synthesizers in the CSAT-6070 deliver superior phase noise performance, exceeding Intelsat specifications by a very comfortable margin. The user receives the benefits of spectral purity and the ability to go into multi-carrier environments with less concern.

THIRD ORDER INTERCEPT

The design of the CSAT-6070 gives the user a high T.O.I. that allows multi-carrier applications without the concerns normally associated with low power environments. The CSAT-6070 delivers performance usually found only in SSPA systems.

SMALL, COMPACT DESIGN

The CSAT-6070 offers a 5-Watt, 10-Watt, and a 25-Watt transceiver in the same basic outdoor enclosure. This design allows quick, easy installation for all basic units in this family of transceivers. With the use of the EDMAC features of the companion CDM family of modems, even installation can be made without the requirement for expensive, heavy test equipment.

FULL MONITOR AND CONTROL

Designed into the CSAT-6070 are a variety of methods to monitor and control this device. The CSAT-6070 offers full Monitor and Control from a small, convenient Hand-Held Terminal or easy access via EIA-232 or EIA-485 connections. Full remote M&C can be achieved through the companion CDM Modem family or the PC Windows based EDMAC proprietary monitor and control software.

Cable connectors used in outdoors application must be sealed to avoid leakage, particularly, N-type connectors. Moisture can seep into junctions at the plug end of the connector, between the fixed and movable parts, and where the cable connects to the connector. Signal attenuation and possible loss of signal can occur in the presence of moisture. All cable junctions must be sealed with a self-amalgamating tape, such as 3M, Type 23 Scotch Self-Amalgamating tape, or equivalent, including military style (MS) connectors.

3.2 TURNING ON THE CSAT

The CSAT does not contain a ‘Power On/Off’ switch. The CSAT is powered ON by connecting the J3 “AC Power” connector to the appropriate prime power source. See Section 1 for detailed requirements for the ‘prime power source’.

Never turn the unit ON without proper termination on the J7 “RF OUTPUT” port. Individuals can be exposed to dangerously high

WARN ING

In addition, when directly connecting the CSAT to Laboratory Test Equipment, a DC block should be used between the J2 ‘RF IN’ port and RF test source. The reason for this is that the CSAT can be configured to supply a 11 Vdc, 400 milliamp, LNA Current Source output on this port. The DC block will protect any test equipment connected directly to J2.

electromagnetic levels.

3.3 CONFIGURING THE CSAT

The CSAT is a complete RF Down Converter Terminal, RF Up Converter Terminal, and RF High Power Amplifier (HPA) in a single weather safe package. The following paragraphs will define the meaning and use of all of the controllable parameter of the CSAT.

3.3.1 F

3.3.2 A

REQUENCY

Both the Receiver frequency and the Transmitter frequency are user configurable. The receiver frequency can be selected to any frequency divisible by either 1.0 MHz or 2.5 MHz in the valid Rx frequency range. The transmitter frequency can be selected to any frequency divisible by either 1.0 MHz or 2.5 MHz in the valid Tx frequency range.

Associated Remote Command(s): DFQ= , UFQ= Example(s) DFQ= 4622.5, UFQ=6836.0

TTENUATION

Both the Receiver attenuation and the Transmitter attenuation are user configurable. The receiver attenuation can be selected between 00.00 and 20.00 dB in 0.25 dB increments. The transmitter attenuation can be selected between 00.00 and 25.00 dB in 0.25 dB increments.

Associated Remote Command(s): DAT= , UAT= Example(s) DAT= 12.75, UAT=12.75

3–3

5 to 25 Watt C-Band Transceiver Revision 0 System Operation MN/XSAT607025.IOM

3.3.3 G

Both the Receiver and the Transmitter Gain Offsets are user configurable. The Gain Offset are only used in redundant configurations. The user can use these parameters to adjust for gain difference between two CSAT Transceivers used in a 1:1 redundant configuration. The offset can be selected between 0.00 and –4.00 dB in 0.25 dB increments.

Associated Remote Command(s): DGO= , UGO= Example(s) DGO= 1.75, UGO=1.00

3.3.4 M

The CSAT offers two operating modes with regards to frequency changes and unit muting. The two modes are; ‘muted after frequency change’ and ‘unmuted after frequency change’.

Associated Remote Command(s): MUT= Example(s) MUT= 0

AIN OFFSET

UTE MODE

• If the Mute Mode is set to ‘1’, the firmware will leave the IF or RF muted following a change to either the Down Converter Frequency or Up Converter Frequency respectively. The operator can then ‘unmute’ the unit using the commands in the next section.

• If the Mute Mode is set to ‘0’, the firmware will automatically ‘unmute’ the IF or RF following a change to the Down Converter Frequency or Up Converter Frequency respectively. This assumes that the unit was ‘unmuted’ prior to the frequency change and that there are no faults following the change. The factory default for this mode is ‘1’.

3.3.5 M

The output state of both the Receiver and the Transmitter are user controllable. The receiver output state (the ‘IF IN’ port, J1) will be ON only if the following two requirements are met:

1. The receiver hardware must be fault free (i.e. No Synthesiser or IFLO faults).

2. The receiver must be unmuted (i.e. DMU=0 ).

The transmitter output state (the ‘RF OUT’ port, J7) will be ON only if the following three requirements are met:

1. The transmitter hardware must be fault free (i.e. No Synthesiser or IFLO faults).

2. The transmitter must be unmuted (i.e. UMU=0).

3–4

UTE

3. The transmitter Amplifier must be ON (i.e. AMP=1).

Associated Remote Command(s): DMU= , UMU= Example(s) DMU=0, UMU=0

3.3.6 TX A

The Tx amplifier ON/OFF state is user controllable. Turning the Tx amplifier OFF removes the 10Vdc supply to the RF Power FETs. The TX Amplifier must be ON in order for the CSAT to transmit a RF signal.

Associated Remote Command(s): AMP= Example(s) AMP=1

3.3.7 C

3.3.8 C

HANNEL SLOPE ADJUST MODE

Comtech EF Data’s CSAT transcievers provide two operating modes for the Receiver IF and Transmitter RF output channel slopes; ‘Calibrated’ and ‘Manual’ modes.

• In Calibrated mode, the CSAT firmware uses a calibration ‘lookup’ table based

• In Manual mode, the customer adjusts the channel slope using the DSA and USA

commands defined in the next section.

Both the Receiver IF output and the Transmitter RF output channel slopes are user controllable.

• The receiver channel slope can be varied for approximately 2dB of positive slope. The parameter for controlling this is the ‘Down Slope Adjust’ which can be varied from 0.0 to 1.0 in 0.1 steps. 0.0 is the default setting and also is the value used when the channel flatness is tuned and tested in the factory. 1.0 corresponds to approximately 2dB of positive slope.

• The transmit channel slope can be varied for approximately 2dB of positive slope. The parameter for controlling this is the ‘Up Slope Adjust’ which can be varied from 0.0 to 1.0 in 0.1 steps. 0.0 is the default setting and also is the value used when the channel flatness is tuned and tested in the factory. 1.0 corresponds to approximately 2dB of positive slope.

Associated Remote Command(s): DSA= , USA= Example(s) DSA=0.0, USA=0.8

3–5

5 to 25 Watt C-Band Transceiver Revision 0 System Operation MN/XSAT607025.IOM

3.3.9 R

A manual, fine adjustment of the internal 10MHz reference frequency is provided as a user controllable parameter. This parameter can be varied within the range 000 to 255, with the factory default setting at 087. Varying this parameter from 000 to 255 will result in a change of approximately 6.5kHz and 4.0kHz at the RF and IF output ports respectively.

Associated Remote Command(s): REF= Example(s) REF=087

3.3.10 E

The CSAT allows the user to select whether or not the summary fault relay is activated if the internal 10MHz reference loses lock with the external reference attached to ‘EXTERNAL REF IN port’ J4.

(The factory default is 0) Associated Remote Command(s): XRF= Example(s) XRF=0

3.3.11 C

The CSAT provides an optional ‘Cold Start’ feature that will ensure that the internal 10MHz reference signal is at a stable temperature prior to allowing the RF and IF outputs to be turned ON. A fixed cold start interval of 15 minutes is used.

EFERENCE FREQUENCY ADJUST

XTERNAL REFERENCE FAULT LOGIC

OLD START FUNCTION

Associated Remote Command(s): CLD= Example(s) CLD=1

3.3.12 A

This parameter defines how the CSAT responds to momentary fault conditions.



If ‘Cold Start’ is ON when the CSAT is powered ON, the IF and RF outputs will remain muted for 15 minutes even if all the conditions defined in 3.2.5 are satisfied. At the end of the 15 minute interval, the RF and IF output will automatically be turned ON if the conditions of 3.2.5 are met.



If a CSAT was powered ON with ‘Cold Start ON’, the operator can override this function by setting ‘Cold Start OFF’.

UTO FAULT RECOVERY



If ‘Auto Fault Recovery ’ is OFF and a fault condition occurs that causes either the RF or IF output to be muted, then that fault condition clears, the CSAT will remain muted. In this mode, operator intervention is necessary to return the CSAT to normal operating mode.

3–6

5 to 25 Watt C-Band Transceiver Revision 0 System Operation MN/XSAT607025.IOM

 If ‘Auto Fault Recovery’ is ON and the same situation occurs, the CSAT will

automatically be unmuted and return to normal operating mode. To protect against repetitive, momentary faults, if the CSAT experiences five occurrences of the same fault, the ‘Auto Fault Recovery’ parameter will automatically be set to OFF.

Example: If the Up Converter IFLO synthesizer goes unlocked and starts sweeping while Auto Fault Recovery is ON, the CSAT would see a unlocked / locked condition at the sweep rate of the IFLO synthesizer. After the 5th occurrence the firmware will set Auto Fault Recovery to OFF and keep the CSAT RF output muted.

Associated Remote Command(s): AFR= Example(s) AFR=1

3.3.13 LNA C

The CSAT has the circuitry necessary to source current, at 11 Vdc, up the “RF IN” port J2, to power a LNA. This current source can be turned ON/OFF via the user. This source is capable of providing up to 400 mA.

WARN ING

IMPORTANT

Associated Remote Command(s): LCS= Example(s) LCS=1

3.3.14 LNA C

The CSAT provides the capability to monitor the LNA current when configured to supply current to a LNA. In addition, an adjustable window detect for the LNA current is provided. After attaching the LNA and turning on the current source, the user can ‘Calibrate’ the current and set a window from ±20% to ±50% to trigger an alarm. The user can disable the ‘window detect’ feature by setting the window value to ±99%. (The factory default is 99)

Associated Remote Command(s): CAL= , LCW= Example(s) CAL= , LCW=40

URRENT SOURCE

Never turn the unit ON without proper termination on the J7 “RF OUTPUT” port. Individuals can be exposed to dangerously high electromagnetic levels.

Exercise care when directly connecting the CSAT to Laboratory Test Equipment. A DC block should be used between the J2 “RF IN”’ port and RF test source to protect the test equipment in case the source is accidentally turned ON. (The factory default is OFF).

URRENT CALIBRATION AND CURRENT WINDOW

3.3.15 LNA F

The CSAT allows the user to select whether or not the summary fault relay is activated if the LNA current moves out the prescribed window. This allows the user to control

Associated Remote Command(s): LFL= Example(s) LFL=0

3.3.16 R

The Operating mode of the Comtech EF Data Redundant Switch Unit (RSU-5060) can be set via a command to the ONLINE CSAT. The RSU-5060 initializes to the AUTO mode when power is first applied.

Associated Remote Command(s): RAM= Example(s) RAM=1

3.3.17 R

The User can cause the RSU-5060 Redundant Switch Unit to switch the position of both the Tx and Rx transfer switches using this command.

Associated Remote Command(s): RTG= Example(s) RTG=

EDUNDANCY CONTROLLER AUTO/MANUAL

• In AUTO mode the RSU-5060 monitors the state of the two CSATs and will automatically switch the OFFLINE unit online if the ONLINE unit faults.

• In MANUAL mode, the RSU-5060 will only switch the position of the Tx and Rx transfer switches when commanded to do so via either the RTG= command or via Pin V on the ‘M&C Control’ connector (J5) on the RSU-5060. The user sets AUTO mode by sending a ‘1’ in the data field and MANUAL mode with a ‘0’ in the data field.

EDUNDANCY CONTROLLER TOGGLE

• If the RSU-5060 is in AUTO mode, the command will only cause a switchover if the OFFLINE unit is currently UNFAULTED.

• If the RSU-5060 is in MANUAL mode, the command will cause a switchover independent of the state of the OFFLINE unit.

Appendix A. REMOTE CONTROL

A.1 INTRODUCTION

This document describes the protocol and message repertoire for remote monitor and control of the CSAT Outdoor terminal.

The electrical interface is either an EIA-485 multi-drop bus (for the control of many devices) or an EIA-232 connection (for the control of a single device), and data is transmitted in asynchronous serial form, using ASCII characters. Control and status information is transmitted in packets, of variable length, in accordance with the structure and protocol defined in later sections.

A.1.1 EIA-485

The EIA-485 interface is provided at the 19-pin circular J5 connector. The interface is a 4-wire EIA-485 interface using the pin out shown in the table below. Since a half-duplex communication protocol is used, the +Tx and +Rx as well as the –Tx and –Rx signals can be tied together at the user end to support a 2-wire interface. The EIA-485 driver is only active during transmission and is tri-stated when not is use.

A.1.2 EIA-232

The EIA-232 interface is provided at the 19-pin circular J5 connector. The interface provides the five signals shown in the table below. The CSAT only requires three wires (TD, RD, and Ground), the other two signal are provided for terminal equipment that requires RTS/CTS handshaking. The CSAT simply ties these two signals together.

Table A-2. EIA-232 interface

Pin Signal Name I/O Notes E EIA-232 RD Input CSAT Rx line G EIA-232 TD Output CSAT Tx line T Ground Passive

A.2 BASIC PROTOCOL

Whether in EIA-232 or EIA-485 mode, all data is transmitted half-duplex as asynchronous serial characters suitable for transmission and reception by a UART. In this case, the asynchronous character format is fixed at; 8 data bits, 1 stop bit, no parity. The baud rate may vary between 1200 baud and 19,200 baud.

All data is transmitted in framed packets. The master is assumed to be a PC or ASCII dumb terminal, which is controlling the process of monitor and control. The master is the only device that is permitted to initiate the transmission of data. Slaves are only permitted to transmit when they have been specifically instructed to do so by the master.

All bytes within a packet are printable ASCII characters. In this context, the Carriage Return and Line Feed characters are considered printable.

All messages from master to slave require a response (with one exception). This will either be to return data that has been requested by the master, or to acknowledge reception of an instruction to change the configuration of the slave. The exception to this is when the master broadcasts a message (such as Set time/date) using Address 0.

TART OF PACKET

A–3

5 to 25 Watt C-Band Transceiver Revision 0 Remote Control MN/CSAT607025.IOM

A.2.1.2 A

Up to 9999 devices can be uniquely addressed. In EIA-232 and EIA-485 applications, the permissible range of values is 1 to 9999. It is programmed into a slave unit using the Set Physical Address (SPA) command.

A.2.1.3 I

This is a three-character alphabetic sequence that identifies the subject of the message. Wherever possible, the instruction codes have been chosen to have some significance.

For example UAT for Up Converter attenuation, UFQ for Up Converter Frequency, etc. This aids in the readability of the message, should it be displayed in its raw ASCII form. All command are case sensitive, only upper case alphabetic characters may be used (A-Z, ASCII codes 65 - 90).

A.2.1.4 I

This is a single character that further qualifies the preceding instruction code. Code Qualifiers obey the following rules:

1. From Master to Slave, the only permitted values are:

= (ASCII code 61) ? (ASCII code 63)

They have these meanings:

The = code (master to slave) is used as the assignment operator, and is used to indicate that the parameter defined by the preceding byte should be set to the value of the argument(s) which follow it.

The ? code (master to slave) is used as the query operator, and is used to indicate that the slave should return the current value of the parameter defined by the preceding byte.

DDRESS

IMPORTANT

NSTRUCTION CODE

The master sends a packet with the address of a slave - the destination of the packet. When the slave responds, the address used is the same address, to indicate to the master the source of the packet. The master does not have its own address.

NSTRUCTION CODE QUALIFIER

For example, in a message from master to slave, UAT=12.50 would mean set the transmit attenuation to 12.50 dB.

For example, in a message from master to slave, ‘UAT?’ would mean return the current value of the transmit attenuation.

A–4

5 to 25 Watt C-Band Transceiver Revision 0 Remote Control MN/CSAT607025.IOM

2. From Slave to Master, the only permitted values are:

= (ASCII code 61) ? (ASCII code 63) ! (ASCII code 33) * (ASCII code 42) # (ASCII code 35)

They have these meanings:

The = code (slave to master) is used in two ways:

• First, if the master has sent a query code to a slave (for example UAT?, meaning what’s the Transmit Attenuation?), the slave would respond with UAT=xx.xx, where xx.xx represents the attenuation in question.

• Second, if the master sends an instruction to set a parameter to a particular value, then, providing the value sent in the argument is valid, the slave will acknowledge the message by replying with UAT= (with no message arguments).

The ? code (slave to master) is only used as follows:

• If the master sends an instruction to set a parameter to a particular value, then, if the value sent in the argument is not valid, the slave will acknowledge the message by replying with (for example) with UAT? (with no message arguments).

• This indicates that there was an error in the message sent by the master.

The * code (slave to master) is only used as follows:

• If the master sends an instruction to set a parameter to a particular value, then, if the value sent in the argument is valid, but the CSAT will not permit that particular parameter to be changed at that time, the slave will acknowledge the message by replying with (for example) with UAT* (with no message arguments).

The ! code (slave to master) is only used as follows:

• If the master sends an instruction code which the slave does not recognise, the slave will acknowledge the message by echoing the invalid instruction, followed by the ! character. Example: XYZ!

A–5

5 to 25 Watt C-Band Transceiver Revision 0 Remote Control MN/CSAT607025.IOM

The # code (slave to master) is only used as follows:

• If the master sends an instruction code which the slave cannot currently perform because of hardware resource issues, the slave will acknowledge the message by echoing the invalid instruction, followed by the # character.

• This response can only occur if the operator sends two or more ‘hardware configuration’ type commands without allowing adequate time between commands for the hardware to be configured.

Example; the operator issued commands to change both the Up Converter frequency and the down converter frequency with less than 100 milliseconds between commands

• If this response is returned the command has not been excepted an the operator must resend the command.

A.2.1.6 E

ESSAGE ARGUMENTS

Arguments are not required for all messages. All arguments are ASCII codes for the characters 0 to 9 (ASCII 48 to ASCII 57), period (ASCII 46) and comma (ASCII 44).

ND OF PACKET

Master to Slave: This is the Carriage Return character (ASCII code 13)
