•synthesised Converter Module 5700
•Solid State Power Amplifier 5705/5710/5720/5730/5740
•low noise amplifier
•transmit reject filter
•Power Supply Unit 5582 (optional)
The five outdoor modules of the transceiver can be mounted on the antenna or feed
support structure. Although a protected position is preferable, the modules are designed
to withstand exposure to outdoor weather conditions.
The modules are supplied with brackets and hardware to enable universal mounting.
Diagrams of significant panels and connectors for this equipment are provided in
Chapter 10, Drawings
Overview
.
Converter module
The converter performs the frequency conversion in the transceiver. It is a single,
integrated outdoor-mounted module (see drawing 03-00959 in Chapter 10, Drawings).
The converter uses dual conversion and synthesised frequency control in 1 MHz
increments. It is protected against transmitting on out-of-band frequencies.
All oscillators are phase locked to the internal reference frequency. The status of all
phase locked loops is monitored at all times. If any loop becomes unlocked, the
converter indicates a fault.
The converter also provides automatic gain versus temperature compensation. This
feature is integrated with the SSPA to provide overall system temperature compensation.
A specific feature of the up/down converter is its low spurious output specification. This
feature makes the system ideally suited to multicarrier applications.
C-Band Transceiver 5700 series Reference Manual3-13
Overview
Solid sta t e power amplifier
The Codan C-Band transceiver is available with either a 5 W , 10 W, 20 W, 30 W or 40 W
SSPA.
Each of these SSPAs has a single power output stage that provides high DC power
efficiency while maintaining excellent multicarrier intermodulation performance.
The SSPA is designed to be mounted on the feed support close to the antenna feed to
minimise transmission losses.
The combination of low power consumption and high speed activation from an external
control line makes the transceiver ideal for solar-powered systems.
Low noise amplifier
The LNA is mounted directly on the antenna feed Rx port. In addition to the standard
LNA, an optional higher performance LNA is available. Other LNAs may also be used.
Any LNAs used with this transceiver must receive its power via either the RF output
connector of the LNA or a separate power and alarm connector.
Transmit reject filter
The TRF is mounted directly on the antenna feed Rx port. It can be used when the
antenna feed does not provide adequate attenuation of the transmit signals at the antenna
feed Rx port.
Power supply unit
The PSU provides DC power to the transceiver from a 50/60 Hz, 115/230 VAC source.
The PSU contains a simple transformer/rectifier supply.
The robust design of the module enables the transceiver to operate reliably when the AC
mains supply is fluctuating (see drawing 03-00993 in Chapter 10, Drawings).
3-14C-Band Transceiver 5700 series Reference Manual
Accessories
There are two accessories available for the C-Band Transceiver 5700 series:
•the Hand-Held Controller 5560
•the Remote Controller 5570
The Hand-Held Controller 5560 is a fully-portable controller that is used to display and
change selected operating parameters of the transceiver.
The Remote Controller 5570 is a rack-mounted controller that is used to display the
operating status and change all operating parameters of the transceiver. This controller
has an in-built security function to protect the parameters of the transceiver from being
changed unintentionally or by unauthorised people.
Both controllers connect to the transceiver via the MONITOR/CONTROL connector on
the converter.
The operation of these controllers is covered in their respective user guides.

How the transceiver works
Converter module
The Converter Module 5700 provides the IF/RF frequency conversion functions required
in a C-Band satellite earth station. It consists of an up converter and a down converter.
Up converter
The up converter converts the Tx IF input signals up to the appropriate Tx RF output via
dual conversion. The actual IF frequency, IF bandwidth and RF frequency are dependent
on:
•the options fitted to the converter
•the IF selected (narrow bandwidth option only)
•the Tx frequency selected
The up converter provides a step attenuator and a gain control prior to the first frequency
conversion with the Tx LO. The gain control compensates for gain variations due to
temperature changes in both the up converter and the SSPA.
The first conversion output signal is filtered by a high-Q interdigital filter, amplified,
then applied to the second conversion stage together with the Tx synthesiser output. The
resultant signal is filtered and amplified to provide the final Tx RF output signal.
Down converter
The down converter converts the Rx RF input signals from the LNA down to the
appropriate Rx IF output via dual conversion. The actual RF frequency, IF bandwidth
and IF frequency are dependent on:
•the options fitted to the converter
•the IF selected (narrow bandwidth option only)
•the Rx (dual synthesiser) or Tx (single synthesiser) frequency selected
The Rx RF input signal is band-pass filtered and applied to the first conversion stage
together with the Rx synthesiser signal. The resultant signal is amplified and filtered
again, then applied to the second conversion stage together with the Rx LO. The second
conversion output is then further amplified and passed through the Rx step attenuator
control to provide the final Rx IF output.
5-2C-Band Transceiver 5700 series Reference Manual
Synthesisers
The synthesisers contain two phase locked loops to produce the required SHF LO
outputs. The resolution of the frequency control is 1 MHz.
For a single synthesiser converter, only one synthesiser is provided and its output is
actively split to produce the required Tx and Rx SHF LOs. In this situation, only the
transmit frequency is programmed. The receive frequency is the transmit freque ncy with
an offset of 2225 MHz.
All oscillators and synthesisers are phase locked to the internal reference frequency.
Control and fault detection
A microprocessor in the converter provides all the control logic and fault detection for
the converter, LNA and SSPA.
The status of all phase locked loops in the converter is monitored and a converter fault is
indicated if any loop becomes unlocked. During an up converter fault period, the
converter inhibits transmission by shutting down power to the final transmit stages.
How the transceiver works
The converter monitors the supply current of the LNA to detect LNA failure and
incorporates overcurrent shutdown circuit protection.
A separate LNA DC/ALARM connector is provided on the converter. It uses a contact
closure from the LNA and current monitoring to detect failure of the LNA.
C-Band Transceiver 5700 series Reference Manual5-3
How the transceiver works
Solid state power amplifier
The SSPA modules 5705 (5 W), 5710 (10 W), 5720 (20 W), 5730 (30 W) and
5740 (40 W) use GaAs FETs to amplify signals in the specified frequency range.
The SSPAs incorporate either a CPR137-G waveguide output, or a N-type connector
output and an integral heatsink.
A cooling fan and shroud are standard on the 10 W, 20 W, 30 W and 40 W SSPAs. The
fan operates whenever the SSPA is activated.
All SSPAs feature high speed activation (<10 ms) from the external REQ SSPA Activate
control line.
The SSPAs are internally protected from damage in conditions of:
•overcurrent
•high temperature
•output short circuit
•output open circuit
5-4C-Band Transceiver 5700 series Reference Manual
Low noise amplifier
The LNA uses HEMT FETs to amplify signals in the specified receive frequency range.
The input is via a CPR229-G waveguide flange and connects directly to the feed to
maintain a low noise input.
Two types of LNA are recommended for operation with the C-Band Transceiver 5700
series—a standard LNA and an optional LNA. The choice is dependent on the system
requirements of the earth station.
The standard LNA has a noise temperature of 40 K and receives its DC supply via the Rx
RF cable.
The optional LNA has a noise temperature of 45 K or 35 K (depending on the version).
This LNA receives its DC supply via a separate DC/Alarm connector.
The LNA can be powered via the Rx RF I/P connector of the converter and the Rx RF
coaxial cable.
How the transceiver works
C-Band Transceiver 5700 series Reference Manual5-5
How the transceiver works
Transmit reject filter
The TRF is a low-pass, waveguide filter. It has a low insertion loss in the specified
receive pass band and high attenuation in the specified transmit reject band.
The increased isolation between the receive and transmit ports provided by the TRF
ensures that the transmit signals will not enter and overload the LNA or down converter.
Depending upon the isolation provided by the OMT, a TRF may not be necessary on
some antennae.
5-6C-Band Transceiver 5700 series Reference Manual
Power supply unit
The Power Supply Unit 5582 is a robust, wide-range power supply. It is specifically
designed to provide the nominal 48 V DC supply required by the C-Band transceiver.
The supply source is 50/60 Hz, 115/230 VAC mains.
The PSU is unregulated and behaves like a simple transformer/rectifier supply. The DC
voltage output to the transceiver will be somewhere between 37 V (at very low mains)
and 72 V (at high mains).
The positive output of the PSU is earthed for protection. An auxiliary 48 V DC output is
provided for powering a redundancy system.

Installation
Installing the outdoor equipment
Ensure you follow all sealing precautions listed in this chapter. If the modules or
cable connections are not sealed correctly, the equipment may be damaged or the
performance of the satellite station may deteriorate over time.
Converter module
The converter can be mounted on a flat surface adjacent to the SSPA, on the antenna
support structures, or on the antenna feed support boom. Although a protected position is
preferable, the module is designed to withstand exposure to outdoor weather conditions.
However, you should avoid areas where water runoff is likely to be channelled into
concentrated streams across any connectors.
The converter is supplied with brackets for mounting on a flat surface. The locations of
the four M8 clearance mounting holes for mounting on a flat surface are shown in
drawing 03-00958 in Chapter 10, Drawings.
Where a flat surface is not available, use the appropriate boom mounting kit for
mounting onto circular or rectangular structures. Fitting instructions for mounting the
converter onto circular or rectangular structures are shown in drawing 15-42000-001
sheet 1 in Chapter 10, Drawings.
Mount the converter so that you have easy access to and a clear view of the control
panel. Also, ensure that the position of the converter allows interconnecting cables to be
run neatly.
For cable interconnection information, see Table 6-1 on page 6-21.
The DC power input is floating. Therefore, either polarity output may be earthed when
connecting the converter to a battery or regulated supply.
The converter has a removable transparent front cover that is sealed with a gasket. There
is a second seal between the control panel and the internal sections of the converter.
T o minimise the chance for moisture to enter the module, the front cover should be taken
off the equipment only when absolutely necessary. Great care should be taken not to
allow rain to enter the control panel area.
Ensure that you use the connector covers supplied with the converter to weatherproof
any unused connectors.
You need to set up the converter after you have installed it (see page 7-2, Setting the
converter option switches).
6-4C-Band Transceiver 5700 series Reference Manual
Solid state power amplifier
Mount the SSPA on the antenna feed support boom with the Tx output as close as
possible to the feed. Ensure that the fan shroud (if fitted) is in the lower-most position
and that the open end of the shroud is facing downwards. You can reverse the shroud by
unscrewing the six M5 socket cap screws (three each side) a few turns.
Although a protected position is preferable, the module is designed to withstand
exposure to outdoor weather conditions. However, you should avoid areas where water
runoff is likely to be channelled into concentrated streams across any connectors.
The SSPA is supplied with brackets for mounting on a flat surface. The locations of the
four M8 clearance mounting holes for the 5 W SSPA and the 10 W, 20 W, 30 W and
40 W SSPAs are shown in drawings 03-00938 and 03-00978 respectively in Chapter 10,
Drawings.
Where a flat surface is not available, use the appropriate boom mounting kit for
mounting the SSPA onto circular or rectangular structures. Fitti ng instructions are shown
in drawing 15-42000-001 sheet 1 or 15-42000-001 sheet 2 in Chapter 10, Drawings.
SSPAs with a waveguide output can be connected to the antenna feed transmit flange
with a length of flexible WR137 waveguide and waveguide bends as required. Ensure all
waveguide joints are correctly gasketed. If you are joining two waveguide flanges that
are both grooved (CPRG type), use a full-thickness gasket. Only use half-thickness
gaskets if one surface is flat, such as with antenna feed flanges.
Installation
If the SSPA has an N-type connector output, use a length of low-loss coaxial cable to
connect it to the antenna feed transmit connector.
You do not need to set up or adjust the SSPA after you have installed it.
C-Band Transceiver 5700 series Reference Manual6-5
Installation
Low noise amplifier and transmit reject filter
T o maintain a good station G/T performance, the LNA should be mounted directly on the
feed receive port.
If a TRF is required, you can bolt the LNA and TRF together before connecting them
directly to the feed receive port.
Ensure all waveguide joints are correctly gasketed. If you are joining two waveguide
flanges that are both grooved (CPRG type), use a full-thickness gasket. Only use halfthickness gaskets if one surface is flat, such as with antenna feed flanges.
DC power through the Rx RF I/P connector of the down converter allows the LNA to be
connected by a single coaxial cable.
Optional LNAs with separate RF output and DC power/alarm connectors can be
powered via the converter by connecting the LNA supply/alarm directly to the LNA DC/ALARM connector on the converter.
Damage may be caused to optional LNAs with separate RF output and
DC power/alarm connectors if DC voltage is present when the LNA is connected
to the Rx RF I/P connector of the converter.
If you are connecting an LNA with separate RF output and DC power/alarm connectors,
check that the appropriate configuration DIP switch on the converter is set to the OFF
position prior to connecting the RF output of the LNA to the RF input of the converter.
To set the LNA +15 V DIP switch:
1Use a 2.5 mm Allen key to remove the transparent cover on the control panel of the
converter.
1Ensure that the LNA +15V switch is OFF (see Figure 6-2).

1Replace the transparent cover on the control panel of the converter.
When you are replacing the transparent cover, ensure the gasket is in place
and that the screws are not overtightened.
For cable interconnection information, see Table 6-1 on page 6-21.
Ensure that you use the connector covers supplied with the converter to weatherproof
any unused connectors.
Power supply unit
You may mount the PSU on the antenna support. Although a protected position is
preferable, the module is designed to withstand exposure to outdoor weather conditions.
However, you should avoid areas where water runoff is likely to be channelled into
concentrated streams across connectors.
The PSU should be positioned with the cable glands at the bottom.
There are two mounting flanges on the top and bottom of the PSU, with six mounting
holes in each flange. The location of the mounting holes is shown in drawing 03-00994
in Chapter 10, Drawings. You can use these holes to secure the PSU to an appropriate
flat surface.
Where a flat surface is not available, use the appropriate pole mounting kit for mounting
the PSU onto circular structures. Fitting instructions are shown in drawing 15-40128-001
in Chapter 10, Drawings.
C-Band Transceiver 5700 series Reference Manual6-7
Installation
Before applying power to the PSU, ensure the installation complies with the
safety precautions listed on page 2-3, Complying with the European Low Voltage
Directive.
The PSU may be damaged if an incorrect voltage is selected or an incorrect fuse
is used.
A protective cover is mounted above the AC input terminal block.
Selecting the operating voltage and checking the fuse
To select the correct operating voltage and check the fuse:
1Locate the Voltage Selector switch on the internal panel of the PSU.
1Using a small flat-bladed screwdriver, position th e Volt age Selector switch for the
required AC mains voltage.
1Using a flat-bladed screwdriver, depress and rotate the cap of the fuse holder 1/8th
of a turn counter-clockwise. Remove the cap.
1Ensure the correct AC line fuse is fitted:
Power supplyFuse
115V5A/250V Delay
230 V2.5 A/250 V Delay
1Re-insert the fuse and cap into the fuse holder.
1Using a flat-bladed screwdriver, depress and rotate the cap of the fuse holder 1/8th
of a turn clockwise. Ensure the cap is locked into position.
For cable interconnection information, see Table 6-1 on page 6-21.
The connection details of the 48 V DC power cable to the PSU or other DC source can
be found in drawing 08-05634 in Chapter 10, Drawings.
The positive output of the nominal 48 V DC supply from the PSU is connected to
the chassis of the PSU and hence the mains supply input earth. Do not connect the
negative output to earth or connect the supply output to equipment in which the
negative supply is earthed.
6-8C-Band Transceiver 5700 series Reference Manual
Grounding recommendations
Precautions must be taken to ensure the installation is adequately protected
against voltage potential differences that may occur between the outdoor and
indoor equipment.
These potential differences may occur:
•if there is a fault in the AC mains reticulation system
•when high power electrical machinery located nearby is switched on or off
•if a lightning strike occurs in the area
It is highly recommended that the antenna metal structures and the cases of the outdoor
equipment be connected together and grounded with earth stakes, or in the case of
rooftop sites, be connected to the lightning grid and earth system of the building. The
chassis grounding screws on the transceiver modules are provided specifically to provide
this protection. This practice will also reduce the likelihood of the mains supply or RF
interfering with the serial interface signals.
Installation
In the case of lightning strikes, huge ground currents occur for several hundred metres
around a strike area, causing large voltage potentials between separate earth points. For
this reason, some lightning engineers recommend the use of large copper earth straps (or
braid) to connect the indoor and outdoor equipment earth systems.
For critical installations in lightning-prone areas, it is strongly advised that you
seek expert advice on lightning protection.
C-Band Transceiver 5700 series Reference Manual6-9
Installation
Welding precautions
When arc welding on or near the antenna structure, take the following precautions to
minimise the danger of large welding currents flowing through the communications
cables:
1Disconnect all cables from the indoor equipment, including power, control and IF
cables.
1Disconnect all cables between the PSU, converter, SSPA and LNA.

Serial interface
The serial interface can be configured for either RS232 or RS422/RS485 interface
standard. The protocol can be configured for either ASCII or packet mode. The most
common mode of interface operation is with RS232 interface and ASCII protocol
selected. All four operating modes are summarised as follows:
Interface/ProtocolApplication
RS232/ASCIINormal RS232 interface for use with a dedicated control
RS422/ASCIIRS422 interface for use with a dedicated control computer

RS422/PacketRS485 interface for use in a multidrop bus computer
Installation

or a ‘dumb’ terminal (long distances)
such as a standard data modem
control environment
When RS422/Packet is selected, four packet protocol options are available:
•CODAN (see page 8-14, Packet protocol)
•Mode 1
•Mode 2
•Mode 3
If you want to use a packet protocol other than CODAN, contact your Codan
representative for more information on the specifications of the alternative
protocols.
The appropriate packet protocol can only be selected when in the ASCII protocol.
When RS422/Packet is selected, there is an option of either 2-wire or 4-wire interface
available.
Set the mode of operation of the serial interface using the appropriate configuration DIP
option switch on the control panel of the converter. The options that can be set include
the data rate, parity, number of bits per byte and the packet address. The packet protocol
and packet address range are not set using the DIP option switches.
C-Band Transceiver 5700 series Reference Manual6-11
Installation
RS232 interface
The RS232 interface is specified as a DCE connection. The RS232 interface is a general
purpose interface for local point to point communications. Descriptions of the interface
connections are as follows:
•RD (receive data)—receive data from the transceiver to the controlling source.
•TD (transmit data)—transmit data to the transceiver from the controlling source.
•CTS(clear to send)—set to the inactive state immediately upon power-on. It is not
•RTS (request to send)—the transceiver transmits serial data either after receiving a
set to the active state until the transceiver is able to accept serial data (that is, it is
held inactive during the power-on reset period and until the transceiver has
performed all its initialisation functions). When it is ready to accept serial data, the
transceiver uses this output to control the data flow from the controlling source.
request for information, at a periodic time for temperature logging, or following a
change in status of the transceiver. In all cases, the amount of data is minimal and
the need to control data transmission from the transceiver is not required. Although
this signal is received, no action is taken by the converter.
•GND (ground)—reference ground connected to the chassis and 0 V.
RS422 interface
The RS422 interface uses a pair of signal lines operating in a differential mode. This
provides much greater distance and noise immunity than the RS232 interface. No
external data flow control signals are used with the RS422 interface.
The RS422 interface is also suitable for multidrop bus applications, where multiple
transceivers or modems are connected to the one controlling source, such as a computer.
In this situation, each RS422 driver on the bus must only switch on when a transmission
from that device is required.
Although no external data flow control signals are used with the RS422 interface, each
bus device internally controls the transmit status of its RS422 driver.
When ASCII protocol is selected in the converter, the RS422 driver is permanently
enabled.
When packet protocol is selected, the RS422 driver is enabled only during the
transmission periods. This method of operation also allows the driver and receiver lines
to be connected together, thus requiring only two wires to interconnect the bus devices
and the controlling source. However, 4-wire operation is preferred as it places less
restriction on the operation of the controlling source.
6-12C-Band Transceiver 5700 series Reference Manual
Installation
Descriptions of the interface connections are as follows:
•Rx+(receive data +)—receive data at the transceiver from the controlling source.
•Tx+(transmit data +)—transmit data from the transceiver to the controlling source.
•Rx– (receive data –)—complement of the receive data at the transceiver from the
controlling source.
•Tx– (transmit data –)—complement of the transmit data from the transceiver to the
controlling source.
•GND (ground)—reference ground connected to the chassis and 0 V.
When operating in a 2-wire mode, the Tx+ and Rx+ signals are connected together and
the Tx– and Rx– signals are connected together.
The general requirement for wiring the RS422 interface is a low impedance (120 Ω)
transmission line (twisted pair) from the controlling source to the bus device that is
farthest from the controlling source.
Connections can be made to the other bus devices along the length of the transmission
line. Under these conditions, only the controlling source and the far end device should be
terminated. All other bus devices should be unterminated. Use the TERM option switch
on the control panel of the converter to terminate the RS422 lines as required.
C-Band Transceiver 5700 series Reference Manual6-13

Monitor and control interface
The MONITOR/CONTROL connector interface of the converter provides relay
contacts to indicate the faults and operational status of the transceiver. The following
contacts share a common contact connection.
SSPA FaultClosed when there is an undervoltage or overcurrent
condition in the SSPA, or if the SSPA is disconnected

To LNA
If you want to use an LNA with the transceiver, and it cannot be powered via its RF
output connector, contact your Codan representative for the appropriate cable
requirements.
If the LNA does not provide the necessary alarm contacts, the alarm contact pins C and
D should be wired together. In this situation, the current monitoring provides the alarm
input.
The LNA DC/ALARM connector of the converter is a MIL-C-26482 10-6S socket.
C-Band Transceiver 5700 series Reference Manual6-17
Installation
Cables
You must use standard shielded Codan cables to make the interconnections as shown in
Table 6-1 on page 6-21.These cables conform with the EMC Directive(see Chapter 2,
C-Band transceiver compliance).
The last three digits of each some part numbers (shown as xxx in Table 6-1) represent a
code for the cable length. This will vary with different cables and systems.
In installations where the cables are not supplied by Codan, the cable requirements in the
Cable fabrication section below should be noted.
For details of the installation requirements, see page 6-19, Cable installation.
Cable fabrication
The 48 V DC power cable is the only cable that does not require shielding (see
page 6-18, 48 V DC power cable (5582 to 5700)).
For connector requirements, see the ‘Cable type’ column in Table 6-1 on page 6-21.
To conform with the EMC Directive(see Chapter 2, C-Band transceiver
compliance), all cables must be assembled as shown in drawings 08-05301,
08-05634 and 08-05618 in Chapter 10, Drawings.
48 V DC power cable (5582 to 5700)
The 48 V DC power cable should be wired as shown in drawing 08-05634 in Chapter 10,
Drawings. The total cable loop resistance must not exceed 0.35 Ω.
Ensure that you use the wire colours specified in drawing 08-05634 to comply
with the EMC Directive (see Chapter 2, C-Band transceiver compliance).
The minimum input voltage required by the transceiver is 37 V DC. Y ou must ensure the
voltage at the DC POWER connector of the converter does not fall below this voltage.
Ensure you take into account the DC power cable resistance and battery/power supply
regulation at full load.
For example, to manufacture a 50 m (164 ft) cable, use 4-core cable, with each wire
50/0.25 (2.5 mm2), approximately 13 AWG. Connect the wires in parallel to produce two
conductors, each with a total cross-sectional area of 5 mm2.
6-18C-Band Transceiver 5700 series Reference Manual
IF cables
The transmit input IF and receive output IF impedances of the converter can be set to
either 50 Ω or 75 Ω. However the converter is only fitted with 50 Ω N-type sockets.
The 75 Ω N-type connector has a centre pin of smaller diameter than that of the 50 Ω
N-type connector. Due to this, the 75 Ω N-type plugs cannot be connected to the 50 Ω
N-type sockets on the converter. If you want to use 75 Ω IF cables, you must fit 50 Ω
N-type plugs to the converter ends of the IF cables.
Cable installation
Installation
When purchasing a 50 Ω N-type plug to use with a 75 Ω cable, ensure the size of
the cable entry point at the rear of the plug is sufficient to fit the thicker 75 Ω
coaxial cable.
The use of 50 Ω connectors in a 75 Ω system operating at IFs of 70 MHz or
140 MHz does not affect performance.
General guidelines
Use the most direct route possible for the cable runs. Secure the cable runs with cable
ties or other suitable clamps.
You may install the indoor/outdoor interconnecting cables underground (for example, in
75 mm PVC pipe), or supported by an overhead catenary wire. Since the transmit and
receive IF coaxial cables are identical, mark the cables at each end before you install
them. Also, ensure that there is enough slack left to make antenna adjustments without
straining the cables.
AC input connection (AC supply to 5582)
Connect the AC mains cable to the PSU using flexible 3-core cable. The cable should be
secured and sealed with the sealing gland supplied. This gland is suitable for cables with
an outer diameter between 5 mm and 10 mm.
Before connecting the PSU to the mains, ensure you take the precautions listed on
page 2-3, Complying with the European Low Voltage Directive.
The mains cable (including any fixed building wiring) should be of sufficient gauge to
ensure that the mains voltage at the mains input of the PSU does not fall by more than
1% when the transceiver is switched on and the SSPA is activated (i.e. 1.2 V @
120 VAC input or 2.4 V @ 240 VAC input).
C-Band Transceiver 5700 series Reference Manual6-19
Installation
Connector sealing
All cable connection points require special care during installation, particularly the
N-type connections. The slightest amount of water in a microwave coaxial connection
will almost completely attenuate the signal.
There are three main areas where N-type connectors leak:
•around the connector junction, where the plug is screwed onto the socket
•the plug itself, between the turning and fixed parts of the plug
•the cable (or heliax) connection to the back of the plug
The connector junction must be well taped with a self-amalgamating tape, such as
3M type 23 Scotch self-amalgamating tape. The tape must cover the connector junction
so that no water can creep into the thread between the plug and socket.
T o prevent water entering the plug, cover between the turning and fixed parts of the plug
with self-amalgamating tape.
It is not sufficient to rely on heatshrink tubing over the connector body to seal the cable
(or heliax) connection to the back of the plug. Even the best heatshrink glues do not
adhere reliably to the outer sheath of the cable or to the shiny metal connector body. It is
essential to tape this area with self-amalgamating tape to prevent water getting into the
back of the N-type plug.
The N-type connections should be carefully taped from the plug/socket junction right to
the cable itself.
All other connectors must also be taped. Although many control and power connections
are made with MS connectors, it is still recommended t hat these junctions are fully taped
in the same way as the N-type connections outlined above. Tape from the fixed
equipment socket (or plug body), right over the cable connector, to the cable sheath.
When using self-amalgamating tape, do not stretch it too much, especially over
the protruding parts of MS connectors. If the tape is over-stretched, it tends to
break away after a few weeks or months.

7-2C-Band Transceiver 5700 series Reference Manual
Selecting mains or battery operation
The Mains/Battery option enables you to select the turn-on voltage of the transceiver.
Selecting the correct turn-on voltage provides clean switch-on and switch-off
characteristics during unreliable voltage supply conditions.
The turn-on voltage required by the transceiver depends on which supply source is used.
If you are using an unregulated supply source, such as the PSU 5582, a high turn-on
voltage (52 V) is required. In this situation, set the MAINS/BATT swit ch to MA INS. For
switch positions, see Figure 7-1.
If you are using a 48 V DC battery system, or a regulated 48 V DC supply, a low turn-on
voltage (42 V) is required. In this situation, set the MAINS/BATT switch to BATT.
The turn-off voltage is 37 V in both cases.

Serial interface control during setup
To set the remaining operating parameters of the transceiver, the transceiver must be
connected to either:
•a Hand-Held Controller 5560
•a Remote Controller 5570
•a terminal (either a dedicated terminal, a personal computer, a laptop or an or ganiser
emulating a terminal)
The connection may be permanent as part of the installation, or temporary, just for the
purpose of setting the operating parameters of the transceiver.
The Hand-Held Controller 5560 or the Remote Controller 5570 provide the simplest and
most convenient way to set the parameters of the transceiver. For details of how to use
the Hand-Held Controller 5560 or the Remote Controller 5570, see the user guides for
these items of equipment.
A serial interface cable is available to connect the transceiver to the serial port of a
personal computer. Connect the appropriate cable (Codan part number 08-05301-002)
between the MONITOR/CONTROL connector of the converter and a PC. This cable
provides a 9-way D-type female connector for connection to the PC. Details of the
wiring of this cable are shown in drawing 08-05301 in Chapter 10, Drawings. If
connection to a 25-way D-type serial port is required, use a standard 25-way female to
9-way male adaptor.
