Section 1: General Information

1.0 Introduction

This section provides the general information for the Teledyne Paradise Datacom LLC line of Redundant Control Panels. The RCP2-1100 and RCP2-1200 are used for 1:1 and 1:2 redundant systems, respectively. The FPRC-1100 and FPRC-1200 are used for Phase Combined Solid State Power Amplifier (SSPA) systems.

This section describes the supplied equipment and safety precautions.

1.1 Description

The RCP2/FPRC controller is used to monitor and control amplifiers configured in 1:1 and 1:2 redundant systems. The RCP2-1100 and FPRC-1100 controllers provide control of two amplifiers and their corresponding transfer switch. The RCP2-1200 and FPRC-1200 controllers monitor and control three amplifiers and two switches.

The RCP/FPRC Series of redundant controller can be used in LNA, LNB, and SSPA systems as well as frequency converter systems. A mimic display on the front panel indicates the RF path and the fault status of the equipment. User interface and control is provided in three forms:

• Front Panel, Local Control

• 37 pin Parallel Control Port with Contact Closures and Opto-Isolated Inputs

• Serial Data Control via RS232 or RS485 (4-wire)

Additional features include:

• Universal Input, Power Factor Corrected Power Supply

• User Friendly Front Panel LCD Display for Local Monitor & Control

• Dual AC Mains Entries with removable power supplies.

1.2 Equipment Supplied

The following equipment is supplied with each unit:

• The RCP2/FPRC Redundant Controller

• (2) IEC Line Cord Sets

• Redundant Controller Operations Manual

Operations Manual, Redundant System Controllers 209351 REV B 9

1.4 Safety Considerations

Potential safety hazards exist unless proper precautions are observed when working with this unit. To ensure safe operation, the user must follow the information, cautions and warnings provided in this manual as well as the warning labels placed on the unit.

1.4.1 High Voltage Hazards

High Voltage for the purpose of this section is any voltage in excess of 30 volts. Voltages above this value can be hazardous and even lethal under certain circumstances. Care should be taken when working with devices that operate at high voltage.

• All probes and tools that contact the equipment should be

properly insulated to prevent the operator from coming in contact with the voltage.

• The work area should be secure and free from non-essential items.

• Operators should never work alone on high voltage devices. There should always

be another person present in the same work area to assist in the event of an emergency.

• Operators should be familiar with procedures to employ in the event of an

emergency, i.e., remove all power, CPR, etc.

An AC powered unit will have 115 VAC or 230 VAC entering through the AC power connector. Caution is required when working near this connector, the AC circuit breaker, or the internal power supply.

1.4.2 High Current Hazards

Many high power devices are capable of producing large surges of current. This is true at all voltages, but needs to be emphasized for low voltage devices. Low voltage devices provide security from high voltage hazards, but also require higher current to provide the same power. High current can cause injury from burns and explosion. The following precautions should be taken on devices capable of discharging high current:

• Remove all conductive personal items (rings, watches, medals, etc.)

• The work area should be secure and free of non-essential items.

• Wear safety glasses and protective clothing.

• Operators should never work alone on high risk devices. There should always be

another person present in the work area to assist in the event of an emergency.

• Operators should be familiar with procedures to employ in the event of an

emergency, i.e., remove all power, CPR, etc.

Operations Manual, Redundant System Controllers 209351 REV B 11

1.4.3 Electrical Discharge Hazards

A spark can not only create ESD reliability problems, it can also cause serious safety hazards. The following precautions should be taken when there is risk of electrical discharge:

• Follow all ESD guidelines

• Remove all flammable material and solvents from the area.

Operations Manual, Redundant System Controllers 209351 REV B 23

3.1 Local / Remote control

Control of the RCP/FPRC can be handled through Front Panel operation, or remotely through Parallel or Serial communication to a computer.

For local (front panel) operation of the controller, simply toggle the Local/Remote key until the yellow LED indicator is illuminated on Local. When in Remote mode the front panel buttons will be inoperative. The indicators and VFD display will still show the status of the system. The Local/Remote key is always operative so that the appropriate mode can be selected. Remote operation enables the serial communication and parallel I/O control.

3.2 Methods of switching

There are three methods of switching converters in a dual 1:1 redundant system.

1. Manual Mode

2. Automatic Mode

3. Physically Rotating either the Tx or Rx Transfer Switch

3.2.1 Manual Mode

The controller is set to Manual mode by toggling the Auto/Manual key so that the yellow LED is indicating Manual mode. Make sure that the Local/Remote key is on Local mode so that the Auto/Manual key is operative. Either unit can be selected online by pressing the amplifier buttons on the mimic display. The online unit is shown by the green LED embedded in the button.

3.2.2 Auto Mode

Automatic Switch mode is entered by toggling the Auto/Manual key until the yellow LED is indicating Auto mode. The online and standby amplifiers can be selected by pressing the appropriate buttons on the mimic display. This configuration will remain until a fault condition occurs. Upon failure, the appropriate fault light will illuminate and switchover will automatically occur.

3.2.3 Physically Rotating Transfer Switch

It is possible to physically rotate the shaft on either the TX or Rx transfer switch to change the online and standby amplifier positions. This can be done either in manual or automatic mode. When the switch is physically rotated in automatic mode the controller will attempt to return the switch to it previous position.

The controller will make two attempts to return the switch before accepting the new position. The front panel mimic display will show the correct switch path settings even when the switch is physically rotated.

26 209351 REV B Operations Manual, Redundant System Controllers

3.3.1.1 Sys Info - Page 1

This page is the system information page of the Sys Info menu. This page shows the

status of both power supplies PS1 and PS2. The controller monitors the output voltage

of each internal power supply. The power supply voltage is considered “Normal” if its output voltage level is above 23V and “Fault” when output voltage drops below 22V. A power supply fault is always considered a major fault.

Also included on page one of Sys Info is the System status. This is the status of the

system summary alarm. The system status will be “Fault” or “Normal” according to the

state of the various fault monitoring circuitry. Aux is the state of the auxiliary fault input. Auxiliary faults are user configurable.

Depending on the system configuration they may be enabled or disabled and track opposite logic states. When auxiliary faults are enabled, they will always trigger a summary fault.

SW1 and SW2 are the position and fault state indicator of the transfer switch / switches

in the system. The possible states are: POS1 - Switch position 1, POS2 - Switch position 2, and Fault. In a system using only one transfer switch SW2 will be displayed as N/A, not available.

Note on Switch Fault:

If the controller cannot read the position indicator lines on the transfer switch it will be considered to be in a fault condition. This can occur when a transfer switch becomes stuck between valid positions. The Summary fault state may or may not be triggered depending on the user settings. The system default is to consider a switch fault as a minor fault and will not trigger a summary alarm.

3.3.1.2 Sys Info - Page 2

This page of the Sys Info menu pertains to the internal monitor and control settings of the RCP controller.

Prtcl is the serial communication protocol settings. The possible settings are:

Auto - Auto detect either Standard or Locus Communications protocol Standard - Standard extended protocol

Baud is the serial communication Baud rate selection. The available Baud rates include:

2400, 4800, 9600, 19200, and 38400.

Interfc is the physical interface used for serial communication. The available interfaces

include RS-232 and RS-485.

Operations Manual, Redundant System Controllers 209351 REV B 27

SysAddr sets the controller unique network address. The address range is 1 to 255.

As with any RS-485 network the RCP address must be unique within every serial network. The controller will answer on serial commands only if its address matches the address sent in the serial packet.

Logic refers to the fault state logic for the External Alarm Input port, J8. The factory

default setting is a logic high state for external alarm fault status. This is consistent with (contact open = fault ) logic used in most systems. However if used in a system that employ reverse logic, this setting can be used to adjust the RCP controller accordingly.

Latch refers to the fault latching function. The possible states are “Enb” and “Dis” for

fault latching enabled and fault latching disabled. The factory default state is for fault latching to be enabled. This means that after a fault has been detected, the RCP controller will continue to indicate an alarm even after the external fault may have been removed. To clear a latched fault the user must press the “Enter” button when the controller is in the Sys Info page.

3.3.1.3 Sys Info - Page 3

This page pertains to the internal monitor and control settings of the RCP controller.

Track refers to the system fault tracking method. Available selections include LNA, EXT

(External), and Both. This option specifies which elements are to be included into the redundant system. The user can select fault tracking based only on internal current monitoring such as in LNA / LNB systems, by external inputs from External Alarm port, J8, or both.

Prior is the Priority control of the system. This option is only used in 1:2 redundant

systems in which priority must be assigned to polarity 1 or polarity 2 of a given antenna system. This is only used if both on line amplifiers fail in a 1:2 redundant system. The priority setting determines the polarity, or switch position, the system should assign to the standby amplifier.

Ctrl specifies Local or Remote mode of controller operation. This function can also be

accessed by the dedicated Local/Remote key on the front panel. When in Remote mode, all other front panel keys are disabled with exception of the Local/Remote key.

Mode indicates and selects the Automatic or Manual mode of the controller. This

function can be accessed by the dedicated Auto/Manual key on the front panel.

Window allows the user to select the current window setting for fault detection in an

LNA / LNB redundant system. The possible selections are: 8%, 12%, 15%, and 20% of the nominal operating DC bias current. The factory default setting is 12%.

Buzzer allows the user to enable or disable the internal audible alarm. The factory

default setting is enabled.

28 209351 REV B Operations Manual, Redundant System Controllers

3.3.1.4 Sys Info - Page 4

This page pertains to the advanced system diagnostic features of the RCP controller.

LNA/LNB Faults refers to state of the controlled state of the LNA/LNB system. This

item shows the fault state of the individual LNA/LNB. If no faults are detected, the word, “None” will be displayed. If fault tracking wasn’t enabled (e.g., if Track option set to Ext – External faults only), the state will be indicated as “N/A” – Not Available. If any LNA related faults are present in the system, this item will show them in format X-X-X, where X could be the number 1, 2 or 3. For example, if LNA1 is in the fault condition, the display will indicate “1----”; if all three LNAs are faulted, “1-2-3” will be displayed.

SSPA Faults refers to the state of the controlled state of the SSPA system. This item

shows the fault state of each individual SSPA. If no faults are detected, the word, “None” will be displayed. If fault tracking wasn’t enabled (e.g., if Track option set to LNA – LNA/LNB faults only), the state will be indicated as “N/A” – Not Available. If any SSPA faults are present in the system, this item will show them in format X-X-X, where X could be the number 1, 2 or 3. For example: if SSPA1 is in the fault condition, the display will indicate “1----”; if all three SSPAs are faulted, “1-2-3” will be displayed.

PS1Out(V) indicates the output voltage of the RCP’s internal power supply 1. The

indicated value shows an instant reading of the power supply voltage with accuracy of

0.1V. Normally, this value should be in a range from 22V to 27V.

PS2Out(V) indicates the output voltage of the RCP’s internal power supply 2. Indicated

value shows instant reading of the power supply voltage with accuracy of 0.1V. Normally, value should be in range from 22V to 27V.

3.3.1.5 Sys Info - Page 5

This page pertains to the advanced system diagnostic features of the RCP controller

Unit1; Unit2; Unit3 – Items refer to the summary fault state of individual units attached

to the RCP. The possible state is “Normal” for non-fault condition, “Fault” or “N/A” as not available.

ExtFaults refers to the state of individual contacts on the RCP external input port. This

item has a subdivision for Auxiliary faults and major SSPA faults. Auxiliary faults are represented as AuxXXX where X indicates the state of individual auxiliary fault sense contacts and could be “1” for “open” state or “0” for shorted to ground state. The leftmost digit indicates the state of Auxiliary Alarm 3 contact and right-most digit shows the state of Auxiliary Alarm 1. For example: if the display shows AUX101, it means Auxiliary ports 1 and 3 are in “open” state (logic “1” state, not connected to the ground) and port 2 is in logic “0” state and are “shorted” to the ground. The actual fault state depends on RCP fault logic and fault handling.

Operations Manual, Redundant System Controllers 209351 REV B 29

Major SSPA faults are represented as HPAXXX, where “X” could be “1” or “0” depending on the state of the individual pin of external faults port. The left-most digit serves as the indicator for SSPA Unit 3 and the right-most for SSPA Unit 1. The fault state of the RCP unit depends on the selected fault logic and selected system type.

For more information about advanced troubleshooting, see Section 4.7. Ux Standby refers to the selected default standby unit. “x” can be a digit from 1 to 3 and

indicates which unit was selected as the default standby unit. This unit is usually selected by the user in the initial RCP setup. The selected unit will remain on standby under RCP manual mode or Auto mode (in condition when all units considered in “Normal” non-faulted condition). Of course, under “Auto” mode, the default standby unit will be put “Online” if required. Under Auto mode, the RCP always keeps track of the unit’s reliability record and can reassign default standby state to the unit with the worst reliability record. The unit will be assigned automatically to the default standby state if its fault state was switched from “Normal” to “Fault” more then 2 times since last user intervention. Any user intervention to the units standby setup will clear all reliability record.

3.3.1.6 Sys Info - Page 6

This page provides additional system information (firmware version 3.7.0 or better).

Operation Mode provides information regarding the current controller operation mode

and switching logic. Indicated status: 1:1 Mode; 1:2 Mode; 1:1 Phase Combined; Dual 1:1 Mode.

Fault Tolerance refers to advanced controller behavior. There are three settings, “None”, “1 Fault” and “2 Faults”, which are set via the Options menu (Section 3.3.5.7).

“None” pertains to no fault tolerance schema. Every fault occurred to the online unit will

take this unit offline permanently. Even after the fault condition is cleared, the unit will stay off line until the user selects otherwise, or other control units develop a fault. No fault tolerance schema is implemented to minimize switching, but not establish preferences to the selected system configuration.

“1 Fault” is the factory default schema, and pertains to one fault tolerance. A faulted

online unit will be automatically set online after the fault is cleared. In case of two sequential fault occurrences, the unit will be set offline permanently. This configuration provides a balanced compromise between minimal fault switching and favoring a particular unit online/standby selection.

“2 Faults” is similar to the “1 Fault” schema, but requires the occurrence of two

sequential faults before changing the favored system configuration.

4.0 Introduction

This section describes various redundant system setups utilizing features available with the Teledyne Paradise Datacom Redundant System Controller.

The controller allows monitor and control of all types of amplifiers, from Low Noise Amplifiers (LNAs), Low Noise Block Converters (LNBs), Solid State Power Amplifiers (SSPA), Solid State Power Amplifiers with Block Up Converters (SSPBs) or vBUC

amplifiers.

4.1 Operation of 1:1 System with RCP2-1100

Figure 4-1 shows the basic block diagram of a 1:1 redundant system. In normal opera-

tion one of the Amplifiers, 1 or 2, is considered the on-line amplifier and the other is in standby. If a fault condition occurs in the on-line amplifier the standby unit can be switched into the circuit by moving the transfer switches on the input and output side of the amplifiers.

Figure 4-2: Indoor/Outdoor Components, 1:1 Redundant System

The LNAs or LNBs are powered by the RCP2-1100 Controller via the control cable. Two power supplies are included in the controller for total system redundancy. The power supplies are diode connected so that only one supply can operate the system.

The RCP2-1100 supplies +15 VDC to power the LNA / LNB and +26 VDC to operate the transfer switch. A failure in an LNA or LNB is typically noted by a change in the DC bias current. The RCP2-1100 has current window comparators that monitor the current drawn by each unit and will report a fault if the current falls outside of the preset current window. The nominal current and window width setting are factory preset to the particular LNA / LNB system, however both are easily adjustable via the front panel

control. A typical 1:1 Redundant LNA system is shown in Figure 4-3.

selections. Press the Main Menu key; select 4.Flt. Setup and press the Enter key; select 1.Mjr. Faults and press the Enter key; select 1.LNA/LNB and press the Enter

key. This puts the RCP2-1100 in LNA/LNB current monitor mode.

4.1.1.2 LNA / LNB Current Calibration

After the RCP2-1100 has been put in the LNA/LNB fault tracking mode, the LNA or LNB nominal current should be calibrated by the controller. To perform the current

calibration, press the Main Menu key; select 6.Calibr and press the Enter key; select

3.Calibrate and press the Enter key. This calibrates the normal current consumption

of the LNA/LNBs.

To select the sensitivity of the alarm detection, select 1.Flt.Window and press the Enter key. Select from four window settings which represent a percentage of the total

current being consumed by the LNA/LNB. The 8% setting is the most sensitive and 20% is the least sensitive. The factory default setting is 8%.

Note: Caution should be used when changing Fault Window settings from the factory

preset. Current variations will occur in equipment naturally as a result of changes in operating temperature. Consideration should be given to environmental conditions and, in particular, to operating temperature extremes.

4.1.2 SSPA 1:1 Redundant System Operation

The RCP2-1100 can be configured to accept external fault inputs at connector J8. The external alarm inputs operate with a closure to ground input. The alarm inputs are opto

-isolated inputs, exposing +5 VDC (open circuit voltage) at 5 mA maximum short circuit current. The external alarm inputs can be driven with an appropriate open collector device or relay contacts. Solid state power amplifier redundant systems typically use a form C relay summary alarm output to drive the RCP2 external alarm input. A

schematic representation of such a system is shown in Figure 4-4.

4.2 Operation of 1:2 System with RCP2-1200

Figure 4-5 shows the basic block diagram of a 1:2 redundant system. In normal oper-

ation amplifiers 1 and 3 are considered the on-line amplifiers while amplifier 2 is in standby. If a fault conditions occurs in either one of the on-line amplifiers, the standby unit can be switched into the circuit by moving the transfer switches on the input and output side of the amplifiers. The amplifiers could be Low Noise Amplifiers (LNAs), Low Noise Block Converters (LNBs), Solid State Power Amplifiers (SSPA), or Solid State Power Amplifiers with Block Up Converters (SSPBs).

The LNAs or LNBs are powered by the RCP2-1200 Controller via the control cable. Two power supplies are included in the controller for total system redundancy. The power supplies are diode connected so that only one supply can operate the system.

The RCP2-1200 supplies +15 VDC to power the LNA / LNB and +26 VDC to operate the transfer switches.

The RCP2-1200 will keep track of the three independent LNA/LNB systems, keeping the link with the most failures in a given time offline. This is reset each time the user manually overrides the system by selecting one of the units from the front panel of the RCP2-1200.

A failure in an LNA or LNB is typically noted by a change in the DC bias current. The RCP2-1200 has current window comparators that monitor the current drawn by each unit and will report a fault if the current falls outside of the preset current window. The nominal current and window width setting are factory preset to the particular LNA / LNB system, however both are easily adjustable via the front panel control.

4.2.2 SSPA 1:2 Redundant System Operation

The RCP2-1200 can be configured to accept external fault inputs at connector J8 (See

Section 2.4.6). The external alarm inputs operate with a closure to ground input. The

alarm inputs are opto-isolated inputs that expose +5 VDC, open circuit voltage, at 5 mA maximum short circuit current. The external alarm inputs can be driven by an appropriate open collector device or relay contacts. Redundant systems typically use a form C relay summary alarm output to drive the RCP2 external alarm input. A typical

block diagram representation of such a system is shown in Figure 4-8.

Figure 4-8: Block Diagram, 1:2 SSPA Redundant System

The external alarm inputs are not limited to SSPA systems. Any device with the appropriate alarm output circuitry could be connected to the external alarm inputs.

To use the external alarm inputs on the RCP2-1200 they must first be enabled from the front panel using the following procedure.

4.2.2.1 External Alarm Tracking

Press the Main Menu key; select 4.Flt. Setup and press the Enter key; select 1.Mjr. Faults and press the Enter key; select 2.External and press the Enter key. This puts

the RCP2-1100 in external alarm monitor mode.

4.3 Operation of 1:1 Fixed Phase Combined System with FPRC-1100

The 1:1 Fixed Phase Combined Redundant System is a popular system architecture that enables two Solid State Power Amplifiers to operate as a normal 1:1 redundant system or a phase combined system. The basic system topology is very similar to a

1:1 redundant system and is shown in Figure 4-9. An additional switch is included

which allows either amplifier to be individually routed to the antenna or connect both amplifiers to a waveguide combiner. The combined system output power is then routed to the antenna. The operation is very similar to the older generation variable phase ratio combiner (VPRC) techniques.

Figure 4-9: Block Diagram, 1:1 Fixed Phase Combined System

System designers find that the 1:1 Fixed Phase Combined Amplifier System topology is a cost effective solution to realizing higher power amplifier systems. For slightly more investment over a traditional 1:1 redundant system, the operator can have the capability of doubling the individual amplifier output power when conditions may require additional power. This is helpful when either atmospheric conditions require more power or if additional satellite traffic requires higher power capacity.

The FPRC-1100 controller is specifically designed to handle such an amplifier system. It not only handles all of the traditional fault monitoring and switching duties but also provides an overall system monitor and control facility. The FPRC-1100 can adjust the system gain over a 20 dB range without the need to adjust each of the amplifiers individually. It also provides a convenient display of the overall system output power. Individual amplifier monitor and control can all be achieved through the FPRC-1100 either locally via the front panel or by remote serial communication.

Operations Manual, Redundant System Controllers 209351 REV B 49

4.4 Operation of 1:2 Fixed Phase Combined System with FPRC-1200

The 1:2 Fixed Phase Combined Redundant System is a popular system architecture that enables Solid State Power Amplifiers to achieve higher output power levels while building in a level of redundancy. The basic system topology is similar to a 1:2

redundant system and is shown in Figure 4-10. Amplifiers #1 and #3 are normally

online. The outputs of #1 and #3 are directed by the waveguide switches into a fixed phase combiner such as a waveguide “magic tee” style combiner. In the event of a failure of either on line amplifier, the standby amplifier, #2, can be switched in place of either #1 or #3 and the system maintains full output power.

Figure 4-10: Block Diagram, 1:2 Fixed Phase Combined System

System designers find that the 1:2 Fixed Phase Combined Amplifier System topology is a very cost effective solution to realizing higher power amplifier systems. For example, it is less expensive to configure a 1 kW C-Band redundant system using (3) 500W Compact Outdoor Amplifiers in a 1:2 Fixed Phase Combined redundant system than it is to use (2) 1 kW amplifiers in a traditional 1:1 Redundant System.

The FPRC-1200 controller is specifically designed to handle such an amplifier system. It not only handles all traditional fault monitoring and switching duties but also provides an overall system monitor and control facility. The FPRC-1200 can adjust the system gain over a 20 dB range without the need to adjust each of the three amplifiers individually. It also provides a convenient display of the overall system output power. Individual amplifier monitor and control can also be achieved through the FPRC-1200 either locally via the front panel or by remote serial communication.

4.5 RCP Remote Control of System SSPAs

RCP units that meet certain conditions are capable of remote control of system SSPAs through the RCP Local Serial Port (J5).

Note: The following features are supported only with RCP2/FPRC/RCPD firmware

version 2.2.00 and above. To verify your unit firmware version browse to the SysID screen on the front panel. If the firmware version is below 2.2.00, the unit’s firmware can be upgraded to the proper version by the user.

Systems may contain up to three amplifiers (consisting of the Teledyne Paradise Datacom Compact Outdoor, Rack Mount SSPAs, or vBUC amplifiers) and a remote RF Power Meter. The SSPAs and RF Power Meter must be connected to the RCP Local Serial Port (J5) via RS485 4-wire or 2-wire interface. All connected components must utilize Teledyne Paradise Datacom String Serial Protocol at 9600 Baud.

If properly configured, the RCP will allow the user to remotely change the Mute Status and Attenuation Level of the connected units, and monitor the Output RF Power. Under such control, all connected units are exclusively controlled by the RCP unit and any new unit added to the system will be automatically adjusted to the selected Attenuation Level and Mute State.

RCP2/FPRC/RCPD units equipped with firmware version 3.30 or later have extended remote system monitoring features, including the ability to monitor and display individual unit temperature and ambient temperature (if the system is equipped with a Teledyne Paradise Datacom remote RF Power Meter). Moreover, the RCP has an additional option to mute a unit sub-system during the period of switchover (see the Switch Mute option description for your particular controller).

Note: The SSPA fault status is not controlled via the serial line, therefore all controlled

SSPA summary alarm lines still have to be connected to the RCP External Alarms Port (J8). A Teledyne Paradise Datacom Remote RF Power Meter can be powered up either from the RCP unit (when remote control mode is enabled, the RCP will automatically turn on its 15V Power supplies) or from an external DC power source with the following characteristics: Output voltage +15V (+/- 3V); Minimum Output Current 300 mA.

Starting with RCP firmware version 3.40, the RCP supports External Reflected Power Monitoring. Monitor unit supports measurement of overall system Reflected Power within 20 dBm range with +/-1 dBm accuracy. The current value of the Reflected power can be viewed on the first informative screen of subsystem menus or accessed through the remote control interface. Outside of specified range, the accuracy of measurement is not guaranteed. If the supplied system is not equipped with this feature, the monitor value of reflected power on the front panel VFD will indicated as “N/A”.

All attached units must be properly configured in order to work under RCP Remote Control. The following parameters must be set for each unit:

1. Serial Protocol to “Normal” or “String”;

2. Selected Baud Rate to 9600;

3. Type of Serial Interface to “RS485”;

4. Unique address selected as follows:

A. SSPA1=1; B. SSPA2=2; C. SSPA3=3 D. Remote RF Power Meter=4.

Refer to your amplifier manual for details.

4.5.2 Using M&C features of RCP to control a SSPA system

All SSPA control-related functions are grouped on the same menu, the SSPA control menu. To access the SSPA control menu, perform the following sequence on the RCP front panel:

1. Press the Main Menu key;

2. Select 5.Options and press the Enter key;

3. Select 6.More and press the Enter key;

4. Select 3.SSPA and press the Enter key.

The SSPA control menu will be displayed on the front panel VFD as follows:

1.Mute 3.Sys.Type

2.Attenuation 4.View

All of the following steps describe RCP remote operation of an SSPA, and assume the user has already selected the SSPA control menu.

4.5.2.1 Change Mute State

To change the overall mute state of a controlled SSPA system from the RCP, perform the following steps:

1. Select 1.Mute and press the Enter key;

2. Select desired Mute state and press the Enter key;

54 209351 REV B Operations Manual, Redundant System Controllers

4.5.2.2 Change Attenuation Level

To change the overall attenuation level of a controlled SSPA system from the RCP, perform the following steps:

1. Select 2.Attenuation and press the Enter key;

2. Select the desired level of attenuation and press the Enter key;

4.5.2.3 Change Switch mute option value

The following option was introduced into the RCP control setup to overcome a problem with microwave arcing, which may potentially damage a switching component if switching RF power exceeds 400 Watts. This particular problem becomes a critical issue if coaxial RF pass switches are used.

In general, all Teledyne Paradise Datacom SSPAs are well protected against high reflected power conditions which may take place during output microwave switchover. But with certainty, waveguide or coaxial switches will develop an internal electrical arc during switchover if the output power is significant. Such conditions, will not lead to instant failure, but over time may diminish some critical RF switch characteristics.

If this option is enabled, the system ability to output RF power will be bonded to the switch position sensing circuitry. This circuitry consists of the following components: a RCP electronic switch position detector; a wiring harness between the RCP and RF switch; and RF switch position sensors. Failure of the above components will lead to break in transmission.

Paradise Datacom LLC strongly recommends not to enable this option unless absolutely necessary.

Note: In order to enable switch muting, the system sub type must be selected to

either CO SSPA, RM SSPA or vBUC! If the system type set to “None,” the switch muting setting will be inhibited.

There are four selections under this option: No muting (“1.SWMute OFF”); internal muting (“2.Internal On”); external muting (“3.External On”) or all switch muting is on (“4.All ON”).

Internal muting refers to the particular RCP unit itself. If the position of one of the controlled RF switches changes or is about to change, the RCP will mute the SSPA subsystem by issuing a special “mute command” over the RS485 serial interface.

When the RF switch position indicator detects that the switch reliably reached Position1 or Position2, a “Mute Off” command will be issued to the SSPA subsystem over the serial interface. If the switch gets stuck between positions, the system will remain muted until the situation is resolved or the Switch Mute option is turned off.

Operations Manual, Redundant System Controllers 209351 REV B 55

4.5.2.4 Units

This option allows the user to select the RF Power measurement units (measured in either dBm or Watts) reported on the front panel and remote interface. Both Forward and Reflected RF power sensor measurements will be affected.

To return to the SSPA control menu, press the “Up” key; to return to the main menu, press the “Main menu key”.

Note: The Forward RF Power Level can be displayed only if a Paradise Datacom

remote RF Power Meter was included in your system. Otherwise, this item will display “N/A” for not available.

SSPA sub system info page 1 pertains to conditions and settings common to all

SSPAs in a subsystem (RCP firmware version 3.10 or better).

Atten.(dB) is the current level of subsystem attenuation. All SSPAs in the system are

adjusted simultaneously and have same level of attenuation.

Mute – indicates the overall mute state of the subsystem. Mute state is applied to all

connected SSPAs, the mute state of an individual SSPA can’t be different then the system mute state.

FrwrdRF(Watts/dBm) – readout from system forward RF power detector (if equipped).

The readout can be represented in Watts or dBms. (see Units menu selection). If the subsystem is not equipped with this power detector, the readout will display N/A.

Ref.RF(Watts/dBm) (RCP firmware version 3.40 or better) – readout from system

reflected RF power detector (if equipped). The readout can be represented in Watts or dBms. (see Units menu selection). If the subsystem is not equipped with this power detector, readout will display N/A.

SSPA sub system info page 2 (RCP firmware version 3.60 or better) pertains to

individual SSPA output power levels.

UnitRFx(dBm) – is the forward RF output level of each individual SSPA. The readout

can be represented in dBms only. The value of an individual forward RF power is measured on the output flange of a particular SSPA. If the SSPA unit is not present in the system, readout will indicate N/A.

56 209351 REV B Operations Manual, Redundant System Controllers

Important! Real system output power most likely will be different from this parameter.

In 1:1 or 1:2 systems, losses in switching and waveguide systems are not accounted. In phase combined systems, real output power will depend on the combining

configuration. For system output power, refer to FrwrdRF(Watts/dBm) on SSPA

4.7 Advanced system level troubleshooting with RCP

The RCP controller offers the ability to control various systems, which can include various subcomponents. In some cases it is important to quickly pinpoint a faulty component without system disintegration. The RCP controller offers such capabilities. The following section describes the troubleshooting procedure for some systems.

4.7.1 Scenario 1

A 1:2 system contains devices connected to the RCP external port (SSPA) as well as an array of LNA devices connected to the Plate assembly port. Major faults are configured to track both types of fault. Fault logic is set to “High”. The RCP indicates a Unit1 fault. To determine which component of the controlled setup is failed, scroll down to System Info Page 4 and verify the status of the “LNA faults” and “SSPA faults” items. One or both items should indicate “1----”.

If the faulted element is found in the LNA setup, the user can double-check what

caused it. Perform the following steps: Press the Main Menu key; select 6.Calibration and press the Enter key; select 4.View CalPoints and press the Enter key. The VFD

will display the advanced LNA/LNB debugging screen, which will show calibration points and current consumption for each LNA. Note the difference between the “LNA1 (mA)” and “Cal1(mA)” values displayed on the screen.

If the faulted element is found in the SSPA setup, double-check the fault causing the problem by selecting Info page 5. Note the state of the “ExtFaults” item, which should indicate “Aux-111 HPA001”. This explains why unit 1 was considered as faulted (note logic “high” state “1” in “HPA001 “).

4.7.2 Scenario 2

In a 1:2 SSPA system with 5 auxiliary devices connected to the RCP external faults port, the RCP utilizes “fault on high” logic. Auxiliary faults are enabled.

An auxiliary fault indicates “Fault” condition. To find which auxiliary line indicates fault, browse to Info page 5. Note the value of “ExtFaults” item.

AUX-[Unit 3][Unit 2][Unit 1], where the “#” in “Unit #” is either “1” or “0”. A “0” indicates a fault and “1” indicates no fault.

So if the value shown on the display is “AUX-011 HPA000”, that indicates a fault state for auxiliary devices connected to auxiliary port lines 2 and 1.

58 209351 REV B Operations Manual, Redundant System Controllers

Section 5: Theory of Operation

5.0 Design Philosophy

The RCP series of redundant controllers was designed to achieve a new level in high reliability, maintenance free operation. A tightly integrated modular assembly approach has been used to realize an extremely versatile controller while maintaining its user friendly operator interface. Five basic building blocks are combined in the RCP redundant controller:

1. Redundant Power Supplies

2. Digital Core Board Assembly

3. I/O Board Assembly

4. Vacuum Fluorescent Display

5. Front Panel Mimic Display

5.0.1 Redundant Power Supplies

A block diagram of the controller is shown in Figure 5-1. Two power supplies are

provided in the controller. These supplies can be connected to two independent AC sources for absolute system redundancy. Either supply is capable of operating the controller and its associated transfer switches. Both power supplies have universal input capability operating over an input voltage range of 85 to 265 VAC and line frequencies of 47 to 63 Hz. The power supplies have a power factor of 0.93 ensuring minimum line harmonic products. Each power supply produces +26 VDC.

The RCP2 provides three channel power outputs for connecting external LNA/LNB units. In standard configuration, each LNA/LNB channel can be selected to supply 13V or 17V with up to 900 mA DC current output. Output voltage is user-selectable either from the front panel menu or over the remote control interface. The -HP model provides an additional 26V 1500 mA output option for use with higher power external equipment.

All channels are protected from overload and will reduce output if the maximum power output capacity is exceeded by an external load.

Note for 26V 1500 mA channel output: In order to provide an equal

load to both internal AC/DC supplies, channels derive their power asymmetrically: Channel 1 from PS2, Channel 3 from PS1; and Channel

2 from either PS2 or PS1. See Figure 5-1. This configuration allows

default standby Channel 2 to power up in case one of the AC/DC power supplies fails. In order to conserve power from the remaining power supply, the LNA/LNB channel will reduce its power output to 13V, 900 mA.

5.0.2 Digital Core Board

The digital core board is the heart of the redundant controller. At the center of the digital core board is the Atmel AVR Mega 103 microcontroller. The microcontroller operates at a clock speed of 7.68 MHz. It provides control functions through the use of an 8 bit wide data bus and 16 bit addressing bus for most of the peripheral devices. A separate UART and collision detector is provided for extremely robust serial interfacing with multi-host networks. All digital I/O lines are protected by opto-coupling or transient absorbing devices. The power supply lines are protected by current limiting devices. The digital core board also contains the interface circuitry that allows the RCP to be firmware upgradeable in the field. A block diagram of the Digital Core Board is shown in

Figure 5-2.

60 209351 REV B Operations Manual, Redundant System Controllers

Figure 5-2: Block Diagram, RCP Digital Core Board

5.0.3 I/O Board Assembly

The I/O Board Assembly contains the primary parallel (hardware) interface circuitry of the controller. It is physically attached to the Digital Core Board by a 40-pin header. The I/O Board provides the +15 VDC supply for the LNB units. Each output can supply up to 600 mA and is completely short circuit protected. The 10 form C relays and opto isolated inputs for the parallel I/O interface are included on this board assembly. A series of rugged N-channel enhancement mode Mosfet devices provide the current sink circuitry to drive either one or two waveguide transfer switches.

5.0.4 Vacuum Fluorescent Display

Rarely found in redundant controllers, the RCP provides a large 2 line by 40 character alphanumeric display. This provides an extremely user friendly interface. The VFD is directly interfaced to the microcontroller via the address and data bus. Virtually all of the controller’s setup and adjustments are accessible from the VFD display. There is no need to access the interior of the controller to make any setup changes.

Operations Manual, Redundant System Controllers 209351 REV B 61

5.0.5 Front Panel Mimic Display

The front panel display is a densely integrated array of LEDs and switches that comprise an important part of the user friendly interface. A great deal of human engineering has gone into the design of this membrane panel. A full complement of alarm indicators are provided along with the mimic display which shows the switch positions of the redundant system. Four separate navigation buttons along with a separate “Enter” button allow the user to easily navigate the firmware menu on the Vacuum Fluorescent Display. Separate buttons have been provided for frequently used functions further enhancing the controller’s ease of use.

5.1 Control Cable Considerations

The RCP series of redundant controllers is designed to drive negative 28 VDC latching style transfer switches. Latching means that the switch has a self cutoff and does not require continuous current consumption. Some commonly used waveguide transfer

switches used in Paradise Datacom Redundant Systems are given in Table 5-1.

Sector -20 to -30 VDC 4 Amps

As Table 5-1 shows, the switch drive current is dependent on the frequency band which determines the physical size of the switch motor. Therefore the system designer must consider the resistive cable losses when choosing a control cable length.

Similarly, the system designer must ensure use of the proper cable insulation for the particular installation. Paradise Datacom uses both Standard Service and Burial Grade for redundant system control cables. Standard Service cable has a PVC jacket which is ultra violet ray (UV) stable in outdoor use. However, Standard Service cable should not be immersed in water or be buried underground for long periods of time. For such applications, Burial Grade cable should be installed.

The RCP controller sources +26 VDC @ 5 Amps maximum to the transfer switch. A typical -28 VDC waveguide switch will operate over a range of -20 to -30 volts. Therefore, the minimum voltage required at the waveguide switch is -20 VDC. Using this as a design guideline, the control cable should be sized so that it does not drop more than 6 VDC from the controller to the switch.

62 209351 REV B Operations Manual, Redundant System Controllers

Paradise Datacom control cables utilize 20 conductors of #18 AWG stranded wire. The control cable schematic is shown in Figure 5-3. The resistance of #18 AWG stranded wire is 6.5 ohms per 1000 feet. The controller switch connector (J3) allows contacts for 2 wires per switch connection. Therefore, two conductors can be paralleled for both the source and return lines for the transfer switch. With a maximum allowable voltage drop of 6 volts, this equates to a 3 volt drop in the source wires and 3 volt drop in the return

wires. This is shown schematically in Figure 5-3. Using four (4) parallel #18 AWG

conductors gives a resultant cable resistance of 1.6 ohms per 1000 feet, or 0.0016 ohms per foot.

SYSTEM CONTROLLER

Figure 5-3: Cable Losses to Transfer Switch

To calculate the maximum cable length that can be accommodated to the transfer switch, first consider the current draw by the switch either from the manufacturer’s data

or from Table 5-1. Next divide this current into 6 volts. This gives the maximum cable

resistance to and from the switch. Finally, divide this cable resistance by 0.0016 ohms/ ft. to find the maximum cable length. This is shown in the following example:

Switch Current draw = 3 Amps 6 V / 3 Amps = 2 ohms 2 ohms/1,250 ft. = 0.0016 ohms/ft.; maximum cable length using (4) #18 AWG connectors

Table 5-2 gives the maximum cable length for some popular switches.

Section 6: Maintenance & Troubleshooting

6.0 Introduction

The RCP series of redundant controllers has been designed to be maintenance free. The only user replaceable parts are the AC input fuses.

6.1 Fuse Replacement

The AC input fuses are 2 Amp Slow Blow style fuses and are accessible at the AC

input entry module. Figure 6-1 shows the location of the input fuses as well as internal

part identification. Note that there is also an on/off switch located on the AC input entry module. The fuse part number is Littlefuse 217002, 2 Amp.

Operations Manual, Redundant System Controllers 209351 REV B 65

6.2 Firmware Programming

The internal firmware is field programmable in the RCP redundant controller. This section details the procedure required to load new firmware into the RCP controller.

6.2.1 Hardware Interface

A connection from J6 of the controller and the parallel (LPT1, LPT2 or LPT3) port of a host PC must be established. This port must be configured for EPP/ECP or bidirectional mode. Connect using an IEEE-1284 Compliant cable (DB25 Female – DB25 Male straight through. This cable is available for purchase in most electronic supply stores). The PC should be running Windows OS (98, NT, 2000 or XP are supported).

6.2.2 RCP Flash Upgrade

Use RCP Flash Upgrade only if a new official copy of firmware is released. Contact the Paradise Datacom U.S. office if you need to upgrade your unit's firmware.

The RCP firmware can be easily updated from the user's PC. A valid copy of the firmware HEX file must be obtained from Paradise Datacom’s U.S. office.

The following files will be provided for the firmware upgrade:

• _code.zip: this zip file contains the programmer software (avreal32.exe); firmware

hex file (~code.hex); executable batch files (prg_LPTx.bat). prg_LPT1.bat for LPT1 prg_LPT2 for LPT2 and prg_LPT3 for LPT3

• dlportio.zip: this zip file contains the parallel port drivers required by Windows OS.

• DisableWarmBoot.reg and EnableWarmBoot.reg - Parallel port behavior manage-

ment utilities.

Step 1: Unpack dlportio.zip onto the target PC. Run the file, Setup.exe.

Step 2: Run DisableWarmBoot.reg. Select OK to add Windows registry key. The key will forbid the Windows parallel port driver from scanning parallel port after system reboot. Reboot the computer.

Step 3: Unpack _code.zip into a temporary folder on the PC (for example, C:\temp). After the files are unpacked, locate the \_code subfolder.

Step 4: Turn off the RCP unit. Connect the PC’s LPT port to the Program Port (J6) at the rear of the unit using an IEEE1284 compliant cable (a “straight-through” DB25 female to DB25 male parallel cable). Turn on the unit’s power.

66 209351 REV B Operations Manual, Redundant System Controllers

Figure 6-2: Firmware Upgrade Terminal Window

Step 5: After all connections have been made and all zip files unpacked, locate the batch file within the \_code subfolder which suits your LPT port designation (For example: prg_LPT1.bat for LPT1 parallel port) and run it. The batch file will open a Command prompt console window and execute the firmware update. Do not interfere with the program until the entire process is complete.

A terminal window with a black background will appear (See Figure 6-2). Watch for

messages on that window while your unit is being updated.

The new firmware becomes active immediately.

Step 5: Optional step. To restore default Windows parallel port behavior run the EnableWarmBoot.reg utility.

6.3 Restoring Factory Pre-set Settings on RCP2/FPRC

The Teledyne Paradise Datacom Redundant System Controller comes with factorypreset settings specific to the default system specifications. This factory setup can be restored at any time either automatically or manually.

Important: Automatic restoration will restore complete factory setup

(including COM settings and miscellaneous fault handling). Manual restoration has to be done one item at a time and only settings critical to system operation will be restored.

6.3.1 Automatic restore

To restore settings automatically, follow these simple steps:

1. On the front panel keypad, press the Main Menu key;

2. Select menu item 5.Options and press the Enter key;

3. Select menu item 2.Restore and press the Enter key;

4. Select menu item 2.Restore Fctry and press the Enter key;

Default factory setup is now restored; sequentially press "Main Menu" and "Enter" to return back to the informative menu sublevel.

6.3.2 Manual restore

Manual setup restoration is dependant on the makeup of your specific system. To undertake a manual setup restoration, follow these directions:

Skip the following steps if the controller is not configured as a primary power source for the system's LNBs.

Re-calibration of LNB's fault window:

14. Make sure the LNBs are reliably connected to the controller;

15. Make sure that all LNBs are normally operational prior to system calibration;

16. Make sure the controller is configured for tracking both LNA/LNB and external faults, if not sure, repeat steps 8 to 14;

17. Press the Main Menu key;

18. Select menu item 6.Calibr. and press the Enter key;

19. Select item 1.Fault Window and press the Enter key;

20. Select item 1.8% and press the Enter key;

21. Press the Main Menu key;

22. Select menu item 6.Calibr. and press the Enter key;

23. Select item 3.Calibrate LNAs and press the Enter key.

The controller should now be configured to work in a VSAT 1:1 Redundancy system.

6.4 Identifying and Replacing a Failed Power Supply

A power supply fault is always considered a major fault, and will cause the front panel Summary Alarm and Power Supply Alarm LEDs to illuminate. To identify which power supply module is faulted, follow these steps:

1. On the front panel keypad, press the Main Menu key.

2. Select menu item 1.Sys Info and press the Enter key.

3. The resulting screen shows the status of both power supplies PS1 and PS2

on the left side of the display. The controller monitors the output voltage of each power supply module. If the output voltage level for a power supply is

above 23V, the display will read Normal. If the output voltage drops below 22V, the display will read Fault.

When looking at the back panel of the RCP, PS1 is on the left and PS2 is on the right.

6.4.1 Removing a Faulted Power Supply Module

To remove a faulted power supply module from the RCP chassis, perform the following steps:

1. Loosen the two captured thumbscrews securing the module to the chassis;

2. Slide the module out of the chassis;

3. Unplug the quick-disconnect power pole connectors.

Operations Manual, Redundant System Controllers 209351 REV B 69

6.4.2 Installing a New Power Supply Module First, ensure that the new power supply module is the same type as the one

beng replaced! See Section 2.6 to review the different power supply module types.

To install a new power supply module into the RCP chassis, perform the following steps:

1. Plug together the quick-connect power pole connectors;

2. Slide the module into the chassis, taking care not to pinch the power cables;

3. Tighten the two captured thumbscrews to secure the module to the chassis.

Section 7: Remote Control Interface

7.0 Overview

A system, which includes a RCP2, can be managed from a remote computer over a

variety of remote control interfaces (see Figure 7-1).

Figure 7-1: RCP2 Remote Control Interface Stack

The parallel port on the RCP unit provides a simple form of remote control. There are 10 form C relay contacts for remote monitoring. There are six opto-isolated inputs for remote control commands. To enable the remote parallel interface simply select remote on the front panel “Local/Remote” button. When in Remote mode all front panel

commands are disabled with the exception of the “Local/Remote” button. See Section

7.1 for details.

The serial interface supports both RS-232 and RS-485 standards. The control protocol

supports two formats: the Normal serial protocol (as detailed in Section 7.2); and an ASCII based protocol suitable for HyperTerminal applications (see Section 7.5).

The Ethernet interface provides the ability to control the system through: IPNet

interface (UDP encapsulated Normal serial protocol – Section 7.6.2); SNMP V1 (Section 7.6.3) or HTTP Web interface (Section 7.6.4).

Operations Manual, Redundant System Controllers 209351 REV B 71

The SSPA subsystem units can also be accessed directly through a packet wrapping

technique described in Section 7.3.1.

Serial protocol format is set at no parity, 8 bit with 1 stop bit. Baud rate is selectable through the front panel.

If using a Terminal mode protocol, the RCP2 provides remote menu access through a HyperTerminal program or through an actual hardware terminal.

The Ethernet interface is fixed to the 10Base-T standard. Normally, straight-through Cat5 cable is used to connect the RCP2 to a network hub, and crossover Cat5 is used to connect directly to a computer’s Ethernet port.

7.1 Remote Control - Parallel

7.1.1 Control Outputs

The hardware behind the form C relay is a single pole, double throw relay. Under normal operation (no alarms) the relays are in an energized state. When a fault occurs or the controller is powered off, the relays are in a de-energized state. The relay contacts are capable of handling a maximum of 30 VDC @ 1A . The form C relay is

shown schematically in Figure 7-2. The form C relay contact outputs are listed in Table 2-2.

7.1.2 Control Inputs

The parallel control inputs are opto-isolated inputs with pull up resistors. To trigger a remote input command, the input should be pulled to ground. The input does not need to be held to ground continuously but it is acceptable to do so. The input only need be pulled low for a minimum of 100 msec. For example, to make amplifier #2 the standby amplifier, pulse pin 36 to ground for 100 msec. If the operator then chooses to make amplifier #1 the standby amplifier, simply pulse pin 37 to ground for 100 msec. The

schematic representation of the control input is shown in Figure 7-3.

The external alarm and auxiliary alarm inputs use the same opto-isolated input circuitry

shown in Figure 7-3.

7.2 Serial Communication

This section describes the normal communication protocol between the RCP2 and a host computer over RS232/RS485 serial interface. Serial port settings on host computer must be configured for 8-bit data at no parity, with 1 stop bit. Baud rate should match selected baud rate parameter on RCP2 unit.

The unit will only respond to properly formatted protocol packets. Figure 7-4 shows the

basic communication packet. It consists of a Header, Data, and Trailer sub-packet.

7.2.1 Header Packet

The Header packet is divided into 3 sub-packets which are the Frame Sync,

Destination Address, and Source Address packets, as shown in Figure 7-5.

7.2.1.1 Frame Sync Word

The Frame Sync word is a two byte field that marks the beginning of a packet. This value is always 0xAA55. This field provides a means of designating a specific packet from others that may exist on the same network. It also provides a mechanism for a node to synchronize to a known point of transmission.

7.2.1.2 Destination Address

The destination address field specifies the node for which the packet is intended. It may be an individual or broadcast address. The broadcast address is 0xFF or 0xAA

(see Section 7.2.5 Multiple Device Access). This is used when a packet of information

is intended for several nodes on the network. The broadcast address can be used in a single device connection when the host needs to determine the address of the amplifier. The RCP2 unit will reply with its unique address.

74 209351 REV B Operations Manual, Redundant System Controllers

7.2.1.3 Source Address

The source address specifies the address of the node that is sending the packet. All unique addresses, except the broadcast address, are equal and can be assigned to individual units. The host computer must also have a unique network address.

7.2.2 Data Packet

The data sub-packet is comprised of six to 32 bytes of information. It is further divided

into seven fields as shown in Figure 7-6. The first six fields comprise the command

preamble while the last field is the actual data.

7.2.2.1 Protocol ID

This field provides backward compatibility with older generation equipment protocol. It should normally be set to zero. This field allows the unit to auto-detect other protocol versions, which may exist in the future.

7.2.2.2 Request ID

This is an application specific field. The amplifier will echo this byte back in the response frame without change. This byte serves as a request tracking feature.

7.2.2.3 Command

The RCP2 protocol is a table based protocol. It allows the user to view and modify data tables located on the controlled device. Throughout the remainder of this description, “sender” will refer to the host PC, and “receiver” will refer to the RCP2 unit.

Sender and receiver are limited to two commands and two command responses. The Get Request command issued by a command sender allows monitoring of existing conditions and parameters on the receiver. The Get Request frame should not have any bytes in the Data Filed and be no longer than 11 bytes.

Operations Manual, Redundant System Controllers 209351 REV B 75

The Response frame from the receiver will contain a Get Response designator in the Command field. If the receiver does not detect any errors in the Get Request frame, the requested data will be attached to the response frame. The length of the Get Response frame varies by the amount of attached data bytes. It may contain 11+N bytes where N is the amount of requested data bytes from a particular table, specified in the Data Length field.

The Set Request command allows the sender to actively change parameters for the receiver’s internal configuration. The Set Request frame must contain a number of bytes in the Data Field as specified in the Data length field. The frame size must be 11+N bytes, where N is the length of the attached data structure. The receiver will respond with a frame where the command field will be set to a Set Response designator. The frame length is equal to the Request frame.

The byte value for each command is given in Table 7-1.

Table 7-1: Command Byte Values

Command Name

Get Request 1

Set Response 2

7.2.2.4 Data Tag

The RCP2 internal structure is organized in several tables, all of which share similar functionality and internal resources. To access the various tables, the data tag must be specified in the request frame. The data associated with certain tags is read only. Therefore only the “Get” command request would be allowed to access these data tags. The RCP2 will return an error on attempts to issue a “Set” request to a read-only table tag. Various tables may contain values formatted either in 1 or 2 bytes format. The Packet Wrapper Tag provides direct access to the RCP2 Local Port and has no

table association. The data tag byte values are given in Table 7-2.

This tag allows access to the unit’s internal Analog to Digital converter. Host access status: Read only. This type of the data cannot be set or modified remotely.

Bytes in Data fields under this tag will be redirected to a RCP Local Port without any change. Data Address field indicates how many bytes (if any) RCP should return from remote device response. Response frame for this tag is not guaranteed. It will depend on remote device response.

7.2.2.5 Data Address / Error Status / Local Port Frame Length

This field is a tag extension byte and specifies the first table element of the tagged data. If the Data Length is more than 1 byte, then all subsequent data fields must be accessed starting from the specified address. For example, if the requestor wants to access the amplifier’s unique network address, it should set data tag 0 (System set-

tings tag) and data address 8 (see Table 7-6, System Settings Details table). If the fol-

lowing Data Length field is more than 1, then all subsequent Settings will be accessed after the Unique Network Address.

Important! In the Response Frame Data Address filed replaced with the Error Status information. The various error codes are given in Table 7-3.

In case of Packet Wrapper request frame (Tag 6), data address field used to specify amount of bytes returned by RCP unit in response frame from local port. Byte collecting from local port starts immediately after wrapped frame being send out. There is no time-out and response frame is not being sent back to host PC until specified amount of bytes collected from Local Port. New request sent by PC host will cancel byte collecting and all collected bytes will be discarded.

7.2.2.6 Data Length

This byte value specifies amount of bytes attached in Data Filed. For Get command it specifies the number of data bytes that has to be returned by RCP unit to a host PC in Response frame. For Set command value of this byte specifies number of data fields to be accessed starting from the address specified in the Data Address byte. In general, Data Length value plus Data Address must not exceed the maximum data size particular tag.

7.2.2.7 Data Field

The actual data contained in the packet must be placed in this field. The “Get Request” type of command must not contain any Data Field. “Get Request” will be rejected if any data is present in the Data Field. Generally, the Bad Checksum error code will be added to the response from the unit. In case the data length is 2 bytes, each data word is placed in the frame with its least significant byte first. All data with length of 2 bytes must be represented as integer type with maximum value range from 32767 to (-32767). Formatting of data bytes for the Packet Wrapper frame is not important for the RCP unit. All data bytes will be redirected to the RCP2 local port without any modification.

78 209351 REV B Operations Manual, Redundant System Controllers

7.2.3 Trailer Packet

The trailer component contains only one byte called the Frame Check Sequence. This

field provides a checksum during packet transmission. See Figure 7-7.

Figure 7-7: Trailer Sub-Packet

7.2.3.1 Frame Check Sequence

This value is computed as a function of the content of the destination address, source address and all Command Data Substructure bytes. In general, the sender formats a message frame, calculates the check sequence, appends it to the frame, then transmits the packet. Upon receipt, the destination node recalculates the check sequence and compares it to the check sequence embedded in the frame. If the check sequences are the same, the data was transmitted without error. Otherwise an error has occurred and some form of recovery should take place. In this case the amplifier will return a packet with the “Bad Checksum” error code set. Checksums are generated by summing the value of each byte in the packet while ignoring any carry bits. A simple algorithm is given as:

Chksum=0

FOR byte_index=0 TO byte_index=packet_len-1

Chksum=(chksum+BYTE[byte_index]) MOD 256 NEXT byte_index

Operations Manual, Redundant System Controllers 209351 REV B 79

7.2.4 Timing issues

There is no maximum specification on the inter-character spacing in messages. Bytes in messages to amplifier units may be spaced as far apart as you wish. The amplifier will respond as soon as it has collected enough bytes to determine the message. Generally, there will be no spacing between characters in replies generated by units. The maximum length of the packet sent to the amplifier node should not exceed 64 bytes, including checksum and frame sync bytes. Inter-message spacing, must be provided for good data transmission. The minimum spacing should be 100 ms. This time is required for the controller to detect a “Line Cleared” condition with half duplex communications. Maximum controller respond time is 200 ms.

7.3 Access optional SSPA subsystem with Packet Wrapper technique

Features introduced in firmware version 4.03 allow send requests directly to a remote SSPA subsystem. In this mode, the RCP redirects requests from its Serial Main or

Ethernet port to its Local serial port, connected to the SSPA (see Figure 7-8). Packet

wrapper requests are associated with longer response times, which have to be accounted in the host M&C software. This mode can be useful for advanced remote diagnostic of the attached SSPA subsystem.

All Packet Wrapper request frames must be “Data Set” command requests.

Each frame intended for redirection must be included in request packet Data Fields.

Packet Wrapping frame M&C should follow the same rules as for any other request frames with one exclusion — the Data Address field will represent the number of bytes expected back from the remote SSPA. These bytes will be redirected back to the Host M&C in the Data Field response packet. The response packet will not be sent until the specified number of bytes is collected in the RCP2 buffer.

Maximum length of the data fields in both directions should not exceed 32 bytes.

In the diagram represented in Figure 7-8, Request frame A is the Packet Wrapper

frame. It contains Request frame B, intended to be redirected to the remote SSPA.
