Installation Guidelines Regarding Power Line Quality
Comtech EF Data has become familiar with the varying quality of the AC
ower grid around the world. The following offers some installation guidelines
IMPORTANT
• 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 LPOD 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 LPOD provides a grounding terminal. This is provided to allow the user to
ground the LPOD to the antenna’s grounding network. All components installed at the
antenna should be grounded to a common grounding point at the antenna.
that should help ensure a reliable installation.
ix
LPOD C-/Ku-Band Outdoor Amplifier/Block Up Converter (BUC) Revision 0
Preface MN-LPOD
• Electrical welding: If welding needs to take place at the antenna, disconnect all cables from
the LPOD except for the ground wire. Cap all RF connections with terminations. This will
prevent damage to the input/output circuitry of the LPOD.
• Lightning: Lightning strikes on or around the antenna will generate extremely high voltages
on all cables connected to the LPOD. Depending on the severity of the strike, the LPOD’s
internal surge protection combined with the recommended external suppression may protect
the LPOD’s 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
(www.polyphaser.com).

1.1 Overview
Comtech EF Data’s LPOD C-/Ku-Band Outdoor Amplifier/Block Up Converter (BUC) – referred
to throughout this manual as the LPOD – delivers its rated power, guaranteed, to the transmit
waveguide flange at the 1 dB compression point. It provides a cost effective, more reliable
replacement for Traveling Wave Tube (TWT) amplifiers in satellite communications.
Comtech EF Data’s extensive experience in the design of outdoor RF transceivers led to the
LPOD family’s efficient thermal and mechanical package. Recognizing the evolution of L-Band
IF systems, the LPOD is designed to eliminate the traditional requirement for the modem to
supply a DC power source and a 10 MHz reference to the BUCs and LNBs.

PS-1 Model PS-2 Model
Figure 1-1. Comtech EF Data LPOD C-/Ku-Band Outdoor Amplifier / BUC

LPOD C-/Ku-Band Outdoor Amplifier / Block Up Converter (BUC) Revision 0
Introduction MN-LPOD
1.2 Functional Description
The compact size and weight of the LPOD lends itself to any installation with limited available
mounting space. These include ship-borne antenna systems, small “flyaway” systems, and
Satellite News Gathering (SNG) installations. The addition of the optional internal reference and
LNB bias T facilitates multi-carrier and redundant operations required of small-to medium-sized
hub installations.
As shown in Figure 1-1, Comtech EF Data’s LPOD is available in two package styles: the PS-1
model and the PS-2 model. Each LPOD consists of a CEFD SSPA module with the
Monitor/Control Processor (MCP), a power supply, and a fan assembly. The amplifier features a
Comtech EF Data low loss combining technique and MCP-based temperature-versus-gain
compensation.
The PS-1 model is always configured as a BUC/SSPA (L-Band in, RF out) with available power
levels to 50W; the PS-2 version can be configured as an integrated BUC/SSPA or solely as an
SSPA (RF in, RF out) at power levels to 250W.
1.3 Features
1.3.1 The Solid-State Advantage
The LPOD is constructed with highly reliable gallium arsenide field-effect transistors (GaAs
FETs). With third order intermodulation products that are 4 to 6 dB better than TWT ratings, the
CEFD unit replaces TWTs with saturated power levels of up to twice the LPOD’s rated output.
The LPODs also provide mean time between failures (MTBF) that is four to five times greater
than the typical TWT MTBF.
1.3.2 Enhanced Standard Features
The LPOD comes equipped with useful features that other manufacturers offer only as options.
Included in the base price are temperature compensation, sample ports (on the PS-2 only), power
monitor, power factor corrected supply, and full remote monitor and control (M&C) capabilities
(including Ethernet and serial).
1.3.3 Built-In Redundancy Controller
The LPOD has the ability to function as a 1:1 (one ba ckup for one primary) redu ndant controller in
a redundant mode without the use of an external device. The optional redund ancy configuration is
implemented by attaching a ganged waveguide/coax transfer switch(es) to the input and output
connectors of the amplifiers, using a combination coaxial cable and waveguide kit.
When the backup LPOD is commanded into redundant mode, it monitors the online LPOD for
faults and status, and automatically maintains a configuration based on the online unit.

LPOD C-/Ku-Band Outdoor Amplifier / Block Up Converter (BUC) Revision 0
Introduction MN-LPOD
A faulted online unit may be disconnected and replaced without affecting the online power
amplifier.
1.3.4 “Smart BUC” Functionality
Comtech EF Data’s unique approach to L-Band/RF frequency conversions eliminates DC and 10
MHz from the input coax. This simplifies redundant and multi-carrier operation. Full 13.75 to
14.5 GHz Ku coverage and 5850 to 6725 MHz C band coverage is offered while supporting
industry standard FSK modem/BUC communications, as well as Comtech EF Data proprietary
commands.
Both LPOD models have a self-contained power supply, eliminating the requirement for the
modem to supply the BUC voltage on the center conductor of the RF cable, simplifying multicarrier operation and modem spares maintenance.
1.3.5 Data Logging Capability
To greatly enhance system maintainability, the LPOD includes a built-in data logging capability.
By recording critical operational parameters (such as temperature, output power, mute status, etc.)
at time stamped intervals, the user can quickly gather intelligence not only about the unit itself,
but also the unit’s operational environment.
1.3.6 Optional Internal 10 MHz Reference
With the optional high stability, oven-controlled crystal oscillator (OCXO) installed, one more
signal is removed from the TX IF cable. This ensures optimum RF performance of the BUC by
eliminating any reference degradation caused by IF combiners, interconnections, or rotary joints.
1.3.7 Optional LNB Support
The LPOD was designed with the evolution of L-band systems in mind. No longer relegated to
low power single carrier installations, L-band IF topologies are now found in larger multi-carrier
installations. A challenge presented by multi-carrier L-band systems is the presence of DC and
reference components on the Tx/Rx L-band interfaces. The LPOD design, by default, eliminates
the DC component from the Tx IF and can eliminate the reference requirement with the optional
internal OCXO. The LNB bias/reference option completes the solution by eliminating DC and
reference signal requirements from the Rx L-band interface.

1.4 Theory of Operation
1.4.1 SSPA Block Diagrams
Block diagrams for the LPOD PS-1 and PS-2 SSPAs are shown in Figure 1-2 and Figure 1-3.
The major components of an LPOD unit are:
• SSPA Module
• Cooling System
• Monitor and Control (M&C)
• Power Factor Corrected Power Supply
Figure 1-2. LPOD PS-1 Block Diagram
1–4
LPOD C-/Ku-Band Outdoor Amplifier / Block Up Converter (BUC) Revision 0
Introduction MN-LPOD
1.4.2 SSPA Module
The amplifier module performs the core function of the unit. An isolator is at the RF input to
ensure good voltage standing wave ratio (VSWR). The RF signal then passes through an
electronically controlled attenuator that adjusts the overall attenuation according to the user input.
After some amplification, a second attenuator is automatically controlled via a look-up table to
maintain the amplifier gain at a constant level over temperature variations.
The RF signal is then amplified by a multi-stage design that utilizes proprietary combining
techniques to meet the rated power requirements. The output circuitry contains a coupler to
provide a sampled signal for monitoring purposes. A power detector circuit also is included and
the reading can be accessed via remote communication. A high power circulator and load is
located at the output to provide good VSWR and protection from external mismatch.
Figure 1-3. LPOD PS-2 Block Diagram

LPOD C-/Ku-Band Outdoor Amplifier / Block Up Converter (BUC) Revision 0
Introduction MN-LPOD
1.4.3 Cooling System
The LPOD contains a robust heat sink and thermal design to maintain a low operating
temperature. The LPOD PS-1 contains one fan that is always on, and the LPOD PS-2 contains
two temperature-controlled fans that are monitored by the M&C board. The fans draw cool
outside air in across the power supply and specialized heat sink. The amplifier module
temperature is monitored and, if for any reason the amplifier temperature exceeds a safe preset
limit, the amplifier module supply is shut down to protect the unit from thermal failure.
1.4.4 Monitor and Control (M&C)
The LPOD includes a microprocessor-based system that provides monitoring and control of the
essential parameters of the unit. The user interfaces with the unit through the M&C system via the
remote control/discrete communications port. The unit is capable of either RS-232, RS-485, or
Ethernet remote communication. A discrete mute control and relay status output is also available.
The M&C system monitors the fan speed (PS-2 only), unit temperature, all power supply
voltages, power transistor currents, output power, etc. Should a critical monitored parameter fail,
the unit will mute the RF signal and report a fault. The details of the fault can be accessed via
remote communication.
The M&C is also capable of acting as a controller in a 1:1 redundant system. When configured as
the back-up SSPA in such a system, it communicates with the other SSPA and toggles the
waveguide switches as necessary.
1.4.5 LNB Operation
Either LPOD package style may be ordered with an optional internal 10MHz reference and Low
Noise Block (LNB) converter bias tee. With these options installed, the user has control of the
bias tee enable (LNB On/Off) as well as the DC bias voltage (On/Off).
1.4.6 Power Supply
The LPOD features a power supply that is power factor corrected. It supplies several voltages
necessary for the unit to operate. The output state of the 10V power supply is controlled by
circuitry within the RF module. If the RF module does not have the –5.8V supply for any reason,
it will not allow the 10V power supply to turn on. This protects the power transistors within the
RF module from failure due to improper power supply sequencing. The +24V output powers the
cooling fans, is the source of power for waveguide switching when the SSPA is used in redundant
configurations, and is dropped to +22V for LNB bias. The +5.8V, -5.8V, +7.8V and +13.5V are
used to operate the M&C board and other overhead functions.

Introduction MN-LPOD
1.4.7 Block Up Converter (BUC) Input
The LPOD translates an L-Band input carrier to the desired output frequency (C-, X-, or KuBand). LO frequencies are as follows:
BUC C, X, Ku, Ka LO Frequencies
Band Frequency LO Frequency Inverting
C-Band 5850 to 6650 MHz 4900 MHz No
X-Band 7900 to 8400 MHz 6950 MHz No
Ku-Band-W 13.75 to 14.50 GHz 12.800 GHz No
Unlike most BUCs, no DC bias voltage should be provided on the center conductor of the L-Band
coax. In addition, the LPOD is available with an internal 10 MHz reference. As, such, no 10 MHz
reference is required on the center conductor of the L-Band coax. If a reference is provided on the
coax, the internal reference will detect and lock to it.

Chapter 3. REMOTE COMMANDS
3.1 Introduction
This section describes the operating features of the LPOD C-/Ku-Band Outdoor Amplifier /
Block Up Converter (BUC). A few key parameters and procedures are summarized, followed by
detailed instructions of remote control communication commands.
3.1.1 RF Input Level
The required RF input level to reach the full rated output power of the SSPA is determined by the
individual amplifier maximum gain and power rating. For example, if the test data of an SSPA rated
for 250W (54 dBm) indicated a gain of 75 dB, then a signal of 54 dBm – 75 dB = -21 dBm would
approximately give the rated output power. Increasing input power beyond this level would result in
an output signal with increasingly higher levels of distortion. Of course, if the LPOD attenuation
control is utilized, a higher level input signal level can be accommod ated. The maximum input level
should never exceed 15dBm, or permanent damage to the unit may occur.
3.1.2 Attenuator Control
The LPOD gain can be attenuated over its specified ra nge by exercising the AT T command. The
details for the format of this command are found later in this chapter.
3.1.3 Mute Control
The LPOD may be muted via software or discrete control. Exercising the MUT=1 command will
“software” mute the unit. The LPOD also may be “hardware” muted by pulling Pin S on the Com
1 / Discrete control connector (J6) to ground (See Chapter 2. SYSTEM CONNECTIONS and
OPERATION).
The Mute command provides over 75 dB of RF on/off isolation. However, the Mute command
only turns off the first few low power stages of the amplifier, the high power stages remain on.
By allowing the higher power transistors to stay on, the LPOD remains in more thermally stable
state should the mute condition be removed.
3–1
LPOD C-/Ku-Band Outdoor Amplifier / Block Up Converter (BUC) Revision 0
Remote Commands MN-LPOD
If the user desires to completely turn off the bias to the entire amplifier (perhaps to conserve
energy in a redundant system), both the
normal transmit operation,
MUT=0 and AMP=1 are required.
MUT=1 and AMP=0 commands should be executed. For
3.1.4 Faults
The M&C system monitors certain key functions of the LPOD for proper operation. Should any
of these parameters exceed predetermined limits, the M&C system will declare a fault. The
conditions that trigger a fault are:
• Any power supply more than ± 10% outside its nominal value
• Fan less than 25% of maximum speed (PS-2 Only)
• I2C internal bus communications fault
• Thermal Shutdown - A temperature fault is indicated if the unit is +>90°C. This creates a
summary fault and will cause the unit to mute itself and switch to the back-up unit (if in a
redundant system). However, the 10V supply to the FET transistors will remain on until
the unit reaches the thermal shutdown temperature of ≥ >95°C. For protection reasons,
the unit will shut down the 10V supply to the power transistors at temperatures >95°C.
3.1.5 Power Detector
A power detector is provided to monitor the output power. It has a useful range of over 20 dB,
referenced to the unit’s rated P1dB point, and its value can be read by exercising the
command. The test data supplied with each unit gives an indication of the excellent accuracy and
flatness of the power monitor over the frequency band of operation.
3.1.6 Some Common Commands
A few of the most common commands and queries are listed below. Full details for each of these
are listed at the end of this section.
•
RMS: Retrieve Maintenance Status. Displays voltages, fan speeds, Heatsink temperature,
output power monitor reading, etc.
•
RCS: Retrieve Configuration Status. Displays current attenuation, mute, amplifier,
online, etc. status.
•
RAS: Retrieve Alarm Status. Displays current alarm or fault status.
3.2 Remote Control Protocol and Structure
This section describes the protocol and message command set for remote monitor and control of
the LPOD.
The electrical interface is either an RS-485 multi-drop bus (for the control of many devices) or an
RS-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 struc ture a nd pro tocol define d i n later s ections .

LPOD C-/Ku-Band Outdoor Amplifier / Block Up Converter (BUC) Revision 0
Remote Commands MN-LPOD
3.2.1 RS-485
For applications where multiple devices are to be monitored and controlled, a full-duplex (or
4-wire) RS-485 is preferred. Half-duplex (2-wire) RS-485 is possible, but is not preferred.
In full-duplex RS-485 communication there are two separate, isolated, independent, differentialmode twisted pairs, each handling serial data in different directions. It is assumed that there is a
‘controller’ device (a PC or dumb terminal), which transmits data, in a broadcast mode, via one of
the pairs. Many ‘target’ devices are connected to this pair, which all simultaneously receive data
from the controller. The controller is the only device with a line-driver connected to this pair – the
target devices only have line-receivers connected.
In the other direction, on the other pair, each target has a tri-stateable line driver connected, and
the controller has a line-receiver connected. All the line drivers are held in high-impedance mode
until one (and only one) target transmits back to the controller.
Each target has a unique address, and each time the controller transmits, in a framed ‘packet’ of
data, the address of the intended recipient target is included. All of the targets receive the packet,
but only one (the intended) will reply. The target enables its output line driver, and transmits its
return data packet back to the controller, in the other direction, on the physically separate pair.
RS-485 (Full Duplex) Summary:
Two differential pairs
Controller-to-target pair
Target-to-controller pair
3.2.2 RS-232
This is a much simpler configuration in which the controller device is connected directly to the
target via a two-wire-plus-ground connection. Controller-to-target data is carried, via RS-232
electrical levels, on one conductor, and target-to-controller data is carried in the other direction on
the other conductor.
3.2.3 Basic Protocol
Whether in RS-232 or RS-485 mode, all data is transmitted as asynchronous serial characters,
suitable for transmission and reception by a UART. The character format should be 8N1 (8 data
bits, no parity, 1 stop bit). The baud rate may vary between 1200 and 38,400 baud.
All data is transmitted in framed packets. The controller is assumed to be a PC or ASCII dumb
terminal, which is in charge of the process of monitor and control. The controller is the only
device that is permitted to initiate, at will, the transmission of data. Targets are only permitted to
transmit when they have been specifically instructed to do so by the controller.
One pair for controller to target, one pair for target to controller.
Pair has one line driver (controller), and all targets have line-
receivers.
Pair has one line receiver (controller), and all targets have tri-state
drivers.

Remote Commands MN-LPOD
All bytes within a packet are printable ASCII characters, less than ASCII code 127. In this
context, the Carriage Return and Line Feed characters are considered printable.
All messages from controller-to-target require a response – with one exception. This will be either to
return data that has been requested by the controller, or to acknowledge reception of an instruction to
change the configuration of the target. The exception to this is when the controller broadcasts a
message (such as Set time/date) using Address 0, when the target is set to RS-485 mode.

Because this is used to provide a reliable indication of the start of packet, these two characters
may not appear anywhere else within the body of the message.
3.2.4.2 Address
Up to 9,999 devices can be uniquely addressed. In RS-232 applications this value is set to 0. In
RS-485 applications, the permissible range of values is 1 to 9999. It is programmed into a target
unit using the front panel keypad.
The controller sends a packet with the address of a target – the destination of
the packet. When the target responds, the address used is the same address, to

its own address.

3.2.4.3 Instruction Code
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: GAC
for Glocal Amplifier Configuration; IPA for IP Address, etc. This aids in the readability of the
message, should it be displayed in its raw ASCII form. Only upper case alphabetic characters
may be used (A-Z, ASCII codes 65 - 90).
3.2.4.4 Instruction Code Qualifier
This single character further qualifies the preceding instruction code. Code Qualifiers obey the
following rules:
1. From Controller-to-target, the only permitted values are:
=
(ASCII code 61
?
(ASCII code 63)
The = (ASCII code 61) is used as the assignment operator, and is used to
indicate that the parameter defined by the preceding byte should be s et to the
value of the argument(s) that follow it. For example: In a message from
controller-to-target, MUT=1 would mean ‘enable the Mute function’.
The ? (ASCII code 63) is used as the query operator, and is used to indicate that
the target should return the current value of the parameter defined by the
preceding byte. For example: In a message from controller-to-target, SWR?
would mean ‘returns the value of the internal so ftw are revision in stalled in the uni t’.
2. From Target-to-controller, the only permitted values are:
=
(ASCII code 61)
?
(ASCII code 63)
The = code is used in two ways:
First, if the controller has sent a query code to a target ( for example: MUT?,
meaning ‘is the Mute enabled or disabled?’), the target would respond with
MUT=x, where x represents the state in question: 1 being ‘enable’ and 0 being
‘disable’.
Second, if the controller sends an instruction to set a parameter to a particular
value, and if the value sent in the argument is valid, then the target will
acknowledge the message by replying with MUT= (with no message arguments).
The ? code is only used as follows:
If the controller sends an instruction to set a parameter to a particular value,
then, if the value sent in the argument is not valid, the target will acknowledge
the message by replying, for example, with MUT? (with no message arguments).
This indicates that there was an error in the message sent by the controller.
!
(ASCII code 33)
*
(ASCII code 42)
The ! code is only used as follows:
If the controller sends an instruction code which the target does not rec ognize,
the target will acknowledge the message by echoing the invalid instruction,
followed by the ! character. Example: XYZ!
The * code is only used as follows:
If the controller sends an instruction to set a parameter to a particular value,
then, if the value sent in the argument is valid, BUT the target is in the wron g
mode (e.g., standy mode in redundancy conf iguration) and willl not permit that
particular parameter to be changed at that time, the target will acknowledge the
message by replying, for example, with MUT* (with no message arguments).
3–5
LPOD C-/Ku-Band Outdoor Amplifier / Block Up Converter (BUC) Revision 0
Remote Commands MN-LPOD
#
(ASCII code 35)
The # code (target-to-controller) is only used as follows:
If the controller sends an instruction code which the target cannot currently
perform because of hardware resource issues, then the target will acknowledge
the message by echoing the invalid instruction, followed by the # c haracter. 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. For example, if the operator
issued commands to change both the frequency and the attenuation with les s
than 100 milliseconds between commands, and if this response is returned,
then the command has not been accepted and the operator must resend the
command.
3.2.4.5 Message Arguments
Arguments are not required for all messages. Arguments are ASCII codes for the characters 0 to 9
(ASCII 48 to 57); period (ASCII 46); and comma (ASCII 44).
3.2.4.6 End of Packet
Controller-to-target: This is the 'Carriage Return' character (ASCII code 13).
Target-to-controller: This is the two-character sequence 'Carriage Return' (ASCII code 13), and
'Line Feed' (ASCII code 10).

Certain commands (denoted by an * in the Parameter Type field) are being marked as EOL.
While these commands are fully supported in this product, it is highly recommended that the
equivelant new commands be used for new implementations. The new commands will generally
follow the outdated commands.

Valid attenuation level (00.00 to 20.00), in dB, in 0.25
dB steps as factory default.
Example: <1/ATT=12.25’cr’
>0001/ATT=’cr’’lf’
Default Value: 00.00
Valid attenuation level (00.00 to 20.00), in dB, in 0.25
dB steps as factory default. This value is not copied to
the offline unit in a redundant system, but will be
added to the attenuation value upon a switchover. This
provides a unit specific fine-tune to maintain power
levels appropriately in a redundant system.
Example: <1/AOF=12.25’cr’
>0001/AOF=’cr’’lf’
Default Value: 00.00
The LPOD output will automatically be muted in the
event of detected fault. If auto fault recovery is
enabled, it will cause the output return to its pre-fault
mute condition if all faults are cleared. If disabled, the
output will remain muted even if all faults are cleared.
Example: <1/AFR=1’cr’
>0001/AFR=’cr’’lf’

installed in the unit, in the form:
Boot:x.y.z Bulk1:x.y.z Bulk2:x.y.z
-orBoot:x.y.zz Bulk1:x.y.zz Bulk2:x.y.zz
The CLC command stores the value of the LNB
Current Supply (in mA) as a reference point. The LNB
current alarm point is then based on this point +/- the
LCW setting.
Note: this command will return a mode error if the LCS
output has not been enabled first.
Example: <1/CLC=’cr’
>0001/CLC=’cr’’lf’
The CLC query will return the value that was stored
during the LNB current calibration.
Example: <1/CLC?’cr’
>0001/CLC=xxx.x
Where:
xxx.x is the calibrated LNB current value in mA.
This command enables, or disables the LNB current
source. Note: LCS must be enabled before the LNB
current can be calibrated with the CLC command.

1: 22kHz enabled, 13V
2: 22kHz disabled, 18V
3: 22kHz enabled, 18V

Example: <1/LDC=0’cr’
>0001/LDC=’cr’’lf’
Default Value: 0
LCW= 2 bytes Command or Query.
This command allows the user to set the alarm window
in ± % of the calibrated LNB Current. Valid inputs are
20 to 50 in increments of 1%. In addition, setting the
value to 99
1
disables the alarm function.
*Note: A return value of 99 indicates that the current
window is disabled. This may be because a value of
99 was set for LCW, or it may be because the CWE
has been disabled. Since the method of setting 99 to
this command is being obsoleted, it is recommended
the user utilize CWE instead of 99.
The following example will set the alarm window to
±30%.
Example: <1/LCW=30’cr’
>0001/LCW=’cr’’lf’
Default Value: 30
CWE= 1 bytes Command or Query.
This command allows the user to enable the current

Alarm mask conditions. If the mask value for a certain
parameter is set to fault then a fault condition will be
registered if specified hardware conditions are not met.
If the mask value is set to alarm then a fault condition
will only appear to be an alarm that will not trigger a
switchover in a redundant system. If the mask value is
set to masked then the fault will never be reported to
the user.

Appendix A. REDUNDANCY
(PHASE 2 RELEASE)
A.1 Introduction to Redundancy Operation
The LPOD can be used in a redundancy configuration by connecting the appropriate 1:1
redundancy cable to the J6 COM1 Connector (see Chapter 2. SYSTEM CONNECTIONS
OPERATION). Once the cable is attached, with the unit placed in redundancy mode via the
correct remote command the system automatically configures the backup (offline) unit by
copying the configuration from the online unit.
A.2 1:1 Redundancy Mode
In 1:1 redundancy mode, the unit that is currently not the active unit (determined by the switch
position) will be the controlling backup unit. The serial command
operation. If
Automatic Redundancy mode. In this mode, if a fault is detected with the active unit, either by
loss of communications between the offline and online unit, or via the summary fault, the backup
(offline) unit will switch the waveguide switch and become the active (online) unit (assuming the
backup unit is not faulted). The backup unit will also poll the active unit at regular intervals in an
attempt to maintain configuration compatibility with the online unit. This ensures that should a
fault occur, the backup unit is configured exactly the same as the active unit.
The
ESW serial command can be used to put the system in Manual mode (redundancy mode off).
With
ESW=0 set in both units, the system is set to manual redundancy mode and no switchovers
will occur upon fault detection. The switch position is determined by which unit receives the
RED=1 command. This command forces the unit to go online, and will force the switch to throw.
Note that a unit may not be forced offline, only an online force is accepted. The user may mute
(MUT) the online unit if required to go offline.
ESW=1 (TX Only) or ESW=2 (TX + RX) in both units, the system will be in
AND
ESW determines system
