1. INTRODUCTION
1.1 General product overview
P7000 L-band Up and DownConverter
This Manual covers the installation and operation of the P7000, P7001, P7001D, P7021 and P7002 family of L band Up and Down frequency converters. A specification for the P7000 L band up and downconverter is incorporated in this manual but is not guaranteed to be the latest specification so please visit our website www.peakcom.co.uk for up to date specifications.
All P7000 series converters are housed in a 1U high 19" rack mount chassis and are designed to connect between a Modem IF, and provide an L band interface as required. The P7000, P7001, P7001D, P7021 and P7002 units are especially suitable for systems requiring an IBS and Eutelsat SMS compliant high stability low phase noise frequency converter for both data and analogue TV signals.
The P7000 P7001, P7001D, P7021 and P7002 units are under constant development and new features may not be included in this manual.
Models covered in this manual:-
P7000 L-Band Up and DownConverter
P7001 Dual L-band to IF DownConverter
P7001D L-Band to IF DownConverter
P7021 S-Band to IF DownConverter
P7002 IF to L-Band UpConverter
The P7000, P7001, P7021 and P7002 units provide a high stability 10 MHz reference signal and 22.5V DC power for both the transmit and receive paths to power an external Block Up and Downconverter. The P7000 series of converters will interface with the Peak CANBUS redundancy units for 1:1, 1:2 and 1:N systems (see RT1000 RT2000 and RCU1800 data sheets)
1.2 Functional description
The P7000 will up convert a 70 ฑ 18 MHz (or optionally 140MHz ฑ36MHz) signal to a frequency within the band 950 to 1700 MHz and will down convert signals within the range of 950 to 2150 MHz to 70 ฑ 18 MHz (or optionally 140MHz ฑ 36 MHz). Both transmit and receive paths feature two stage frequency conversion and can be set to a frequency resolution of 1 Hz. The unit features a large graphic LCD display, membrane keyboard and menu driven software for control and configuration of the unit. The units have built in 1:1 and 1:2 redundancy control and can be remotely controlled via a RS232/485 port.
The P7000 is fully software controlled; there are no links or switches used to configure the unit. This enables all control and configuration to be programmed either locally or by remote control. All the configuration parameters are stored in non-volatile memory that will retain data for a minimum of 5 years with no power applied.
The P7021 will function in exactly the same way as a P7001 down converter, with an input of S-Band 2200MHz to 2300MHz.

1.4 Review of P7000 Specification parameters
1.4.1 Upconverter Input
70 18 MHz or option 140 36MHz
If the converter is set to output a frequency of 1200MHz then the centre frequency at 70 MHz (or 140MHz) will convert to this frequency. If you change the input frequency across the IF input band at 70MHz (using for example the modem frequency output control) without changing the output frequency then the output will be correspondingly lower/higher in frequency. If you input, for example 65MHz with the converter frequency set to 1200MHz the output will actually be 1195MHz. At all times the bandwidth of the signal should be calculated / measured so the 18 MHz at 70MHz (or 38MHz at 140MHz) is not exceeded.
1.4.2 Upconverter Output
950 - 1700 MHz
Centre frequency for a 70MHz (or 140MHz) input. A consideration of your signal bandwidth should be made because at 950MHz the lowest available frequency is 950-18MHz=932MHz which means you could transmit out of band.
1.4.3 Downconverter Output
70 18 MHz or option 140 36MHz
As above for an upconverter output, if the converter is set to input a frequency of 1200MHz then the centre frequency at 1200MHz will convert exactly to 70MHz (or 140MHz). If you input a frequency not exactly at the input frequency then the output will be similarly lower or higher by the same amount
1.4.4 Downconverter Input
950 - 2150 MHz
Range of limit of input
1.4.5 Frequency resolution
1 Hz
Output frequency step size. On the LCD screen this is 0.000001MHz if the L-Band frequency is viewed or 0.000000001GHz if the SHF LO addition feature is switched on.
1.4.6 Phase noise (dBc/Hz)
-73 @ 100 Hz; -76 @ 1 kHz; -85 @ 10 kHz; -93 @ 100 kHz; -110 @ 1 MHz
At 100Hz away from the carrier the average relative intensity of the carrier in CW mode at that point is 73dB lower than the centre frequency
1.4.7 Group delay
Linear 0.025nS, Parabolic 0.015nS/MHz2 , Ripple 1nS p-p.
The relative timing distortion imposed on a signal passing through the converter within the 18MHz band at 70MHz. This is due mainly to the internal filters. The group delay profile is described mathematically as follows
The linear function describes the straight line slope across the 36Mhz range. At 0.025nS over 36MHz the slope across the pass band calculates to 0.025x36=0.9nS.
The parabolic function is a quadratic function and can be converted at any point to a linear function by multiplying the specification parameter by the square of the frequency offset. For example for a Parabolic specification of 0.015nS/MHz2 at a frequency of 60MHz the offset is 10MHz (70-60). This can be expressed in the form of an actual delay by calculating (70-60) squared times 0.015nanoseconds which is 100x0.015=1.5nS. This figure is always positive and the corresponding frequency at 80MHz calculates in this example to the same figure of 1.5nS. Note that the group delay is defined for a 70MHz IF and the group delay for a 140MHz is considerably improved especially the parabolic function.
The ripple parameter defines the limits of the balance of the group delay distortion after the linear and parabolic functions have been subtracted. This distortion is not necessarily a sinusoidal waveform and is important when considering high symbol rates
1.4.8 Upconverter Conversion gain
-10 to +20dB ฑ 2dB min stepped 0.1dB
The gain of the converter can be set to lose 10dB through the conversion process or gain 20dB. The finite gain set is specified to be within 2dB of the setting and the step size is 0.1dB. The tolerance of the step size is not specified but should not exceed 0.05dB per step.
1.4.9 Downconverter Conversion Gain
0 to 30dB ฑ 2dB min stepped 0.1dB
The gain of the converter can be set to have no gain at 0dB or a gain of 30dB. The finite gain set is specified to be within 2dB of the setting and the step size is 0.1dB. The tolerance of the step size is not specified but should not exceed 0.05dB per step.
1.4.10 Gain flatness
ฑ 1 dB full band, ฑ 0.5 dB, across any 36 MHz in band
The slope and variation of power across L-Band should be within 2dB top to bottom but 1dB across any 36MHz
1.4.11 1 dB comp. point
Output +10 dBm, Input -10 dBm
The 1dB compression point is a finite point in the power scale where a 1dB input only gives 0.5dB increase in power. At full gain of +20dB the output stage of the unit will compress before the input stage and conversely at gains of less than 20dB the input stage will compress before the output stage. Note also the values specified are for total composite power and not single carrier.
1.4.12 Upconverter Output spurious
<-60 dBm (in band non-carrier related), <-60 dBc in band (in band carrier related)
All converters generate spurious signals due to Local Oscillator leakage inside the unit and possibly some mixing products of these oscillators. These signals are always present to some degree and are not related to the carrier signal being present so are specified as a maximum finite power in dBm and are always measured at full gain.
Other signals associated with the carrier are also specified but relative to the carrier (dBc) and again measured at full gain. During manufacture only out of band signals in the minimum/2 and maximumx2 range are considered. Note that these spurii will be seen to change in finite value when gains other than full gain are selected due to switching of some internal attenuators.
A typical setup is to set a converter input power of -20dBm and an output of 0dBm. Consideration of spurii should be made if the input power is significantly reduced as low input power will give a worst spurious to signal ratio.
1.4.13 Invert Spectrum
In a conversion process if the Local oscillator used is of higher frequency than the Input frequency then the output will be spectrum inverted. This means that the High Frequency side of an FM signal will come out at the Low Frequency side of the centre frequency. To decode a signal the decoder must know whether the signal is inverted and somewhere in the system there must be a mechanism to re-invert the signal.
A classical example is the 5.15GHz oscillator used in a C-Band LNB. To convert the 3.4 to 4.2GHz band to 950MHz to 1750MHz a 2.45GHz LO is the calculated frequency. Unfortunately this 2.45GHz LO gives a problem due to twice the LO mixing with the input to give an interfering signal (4.9-3.4=1.5). A 5.15GHz LO is therefore used to avoid this problem and consequently the L-Band to 70MHz converter (P7001) has to have INVERT enabled to preserve the spectrum. It is not normal to transmit inverted.
1.4.14 Auxiliary DC output
22.5 volts regulated @ 0.5 amp, software switchable
This facility is used for driving an external L-Band to SHF Block Up Converter on an Upconverter and an LNB on a Downconverter. This voltage is integrated with the L-Band signal (and 10MHz). This voltage is out of a regulator and will pull down to zero without damage however the internal fuse may be damaged if this happens.
1.4.15 10MHz reference output
0 dBm nominal, software switchable
This facility is used for stabilising the output frequency of an external L-Band to SHF Block Up Converter. This signal is integrated with the L-Band output signal. An outdoor BUC will drift in frequency due to ambient temperature changes causing changes to the BUC locking crystal inside the unit. Inside Peak BUCs and BDCs the facility is made to pick up the 10MHz locking signal sent by the P7000 and lock to the internal crystal. With the BUC locked to the indoor unit the stability of the BUC unit is as good as the internal P7000 crystal. With very long cables caution should be taken not to attenuate the 10MHz (and DC) too much.
1.4.16 L band output/input monitor
Provides monitoring of the L-Band signal at -20dBc.
Cannot be used as an input.
Full band spectrum is available
1.4.17 Reference frequency
Internal 10 MHz frequency, trimmed by software.
Uses a high grade OCXO at 10MHz.
External reference input: Will accept either 5 or 10MHz.
Stability <5 x 10-11 per second, ageing <7.5 x 10-8 per yr, 5 x 10-10 per 12 hrs
1.5 Mechanical description
The P7000 Series of converters are housed in a 19 inch 1U high chassis, suitable for rack mounting. It is 534 mm deep and may be fitted with rack slides if required. Figure 2 shows views of the front and rear panels of the P7000 series L-Band Up/Down converters.
At the front of the unit is the keyboard, LCD display and LED indicators. The operator is prompted by messages displayed on the LCD to enter data via the keyboard. In this way the P7000 may be configured for use, and the set up changed, if necessary. The LEDs provide a quick visual indication of the operational status of the unit.

1.7.10 Redundancy
This is a 9 pin male 'D' type connector. The P7000 has a built-in 1:1 and 1:2 redundancy controller. A pair of P7000 units is required for correct operation plus R1000/2000 and T1000/2000 units.
1.8 Fault philosophy
Fault conditions are divided into two categories;
a) MAIN UNIT COMMON FAULTS; Faults with internal items that on a P7000 are common to both the Up & DownConverter (Main power supply assembly etc).
b) DEVICE SPECIFIC FAULTS; Faults that are specific to the Up or DownConverter assembly. These can include external fault inputs.
Most faults as shown below activate the summary ALARM on the unit, this will force a change-over if used in a normal redundant system.
The only fault that does not cause the unit to go into ALARM is the External Mute.
All faults shown below are reported on the front panel LCD and turn the tri-colour fault LED to red.
Green No faults

Avoid exposing the packaged or unpackaged product to extremes of humidity or moisture (including condensation). In the event that this does occur, the product should be left at room temperature for in excess of 5 hours to dry naturally before application of prime power.
2.1.4 Cleaning & Maintenance
The product is designed to be installed and operated in a clean air environment. Apart from occasional cleaning of the front panel, no regular cleaning &/or maintenance is necessary.
Always ensure that the product is off-air and that the mains supply is isolated before attempting to clean the front panel. Cleaning of the front panel can be accomplished with a damp cloth. Do not use excessive amounts of water & do not use detergents or other cleaning agents without first consulting Peak Communications.
2.2 Mechanical Installation Considerations
2.2.1 Mounting
This product has been designed to mount in a standard IEC 19 inch racking system, but can also be used free standing or mounted in a standard IEC flight case.
The product is of standard 1U height (1.75 inch) and depth of 534mm (21 inches). Standard connector mating parts with cable bend radii, plus space to uncouple connectors, can add a further 80mm (3.15Inches) to this depth & should be considered when designing the installation.
The product is provided with standard 19 inch rack front panel fixing points, however these should not be solely relied upon to support the entire weight of the unit. Four (two on each side) additional M3 mounting points are provided along the sides of the unit, These can be used to support the unit from rack slide rails or other side support mechanisms, alternatively shelving brackets can be used to provide rest support for the units.
Cooling slots are provided on the sides of the unit, care should be taken to avoid blocking these when designing the installation (see Cooling section below).
When several products are to be mounted on top of one another in a rack system, they should not be stacked without individual support. Stacking of units without adequate mechanical support and isolation can degrade microphonic performance of the overall system and hamper maintenance activities.
2.2.2 Cooling
These products dissipate <100W internally and contain an internal forced air cooling system. Air intake and exhaust apertures are provided on the side panels of the chassis, care should be taken to avoid blocking these when designing the installation
Although these products have been designed to operate with a full rack packing density in an ambient of 50ฐC, for operational reasons it may be necessary to allow extra space if the unit is sandwiched between two longer chassis, or if the rack ambient increases above 50 degrees C. This will be necessary if adjacent equipments transfer significant heat to the Converter surfaces, through either conduction or convection.
A thermal sensor is fitted to the unit which provides an over temperature alarm
2.3 Prime Power Supply & Connection
The safety notes provided in the product compliance section of this handbook should be read before connecting this product to the mains supply.
This product can be operated from mains supplies of 100-132Va.c. or 200-230V a.c. (50/60Hz), the appropriate voltage range is automatically selected by the unit and requires no user intervention. The IEC standard mains inlet on the rear of the unit includes a double pole switch.
The typical power requirement of these units is <100W.
The equipment is classified in EN 60950 as pluggable equipment, class A for connection to the mains supply, as such it is provided with a mains inlet cord suitable for use in the country of operation. In normal circumstances this will be of an adequate length for installation in the rack. If the mains cord proves to be too short, then any replacement must have a similar fuse type (if fitted) and be manufactured to similar specifications: check for HAR, BASEC or HOXXX-X ratings on the cable. The connector ends should be marked with one of the following : BS1636A (UK free plug 13 amp); BSI, VDE, NF-USE, UL, CSA, OVE, CEBEC, NEMKO, DEMKO, SETI, IMQ, SEV and KEMA-KEUR for the IEC 6 amp free socket. Schuko and North American free plugs must have similar markings.
The installation of the equipment and the connection to the mains supply must be made in compliance to local or national wiring regulations for a category II impulse over voltage installation. The positioning of the equipment must be such that the mains supply socket outlet for the equipment should be near the equipment and easily accessible or that there should be another suitable means of disconnection from the mains supply.
2.3.1 Fuses
The equipment is provided with short circuit fuse protection of both the Live and
Neutral conductors, both fuses must be functional before the unit will operate.
The fuses are accessible from the rear of the unit and are fitted into the IEC mains
inlet. To check or replace a fuse, switch off and isolate the mains supply before
removing the fuse cover. If a replacement fuse is required, then an equivalent type and
rating must be used. The fuse size is 5 x 20 mm, rated at 5A anti-surge (T5A).
2.3.2 Earthing
The equipment is designed to operate from a TN type power supply system as specified in EN 60950. This is a system that has separate earth, line and neutral conductors. The equipment is not designed to operate with an IT power system which has no direct connection to earth.
An external protective earth, providing protection against RF and transient currents, should be connected between the rear panel earth stud (adjacent to the prime power inlet point and fitted with an M4 nut) and a local system earth point.
2.4 Other Interface Connections

These are provided on the rear panel and have the following characteristics;
Converter Type Connection Type Panel Label Impedance
UpConverter N-type (F) Tx Out 50Ω
DownConverter N-type (F) Rx In 50Ω
The use of high quality cables and connectors for L-band signals is strongly recommended. Cables and connectors should be rated for operation up to 2200MHz. Care should be taken when handling these cables, avoiding stress to connections, tight bend radii and damage from sharp objects, all of which can degrade system performance.
These connections can also be used to interface the 10 MHz reference signal (at a nominal 0dBm level) and the DC power (22.5V @ 0.5A) to the external Block Upconverter/DownConverter.
2.4.2 L-band Monitor Output Connections
These are provided on the rear panel and have the following characteristics;

When using this product with the serial communications interface, a 120Ω bus termination should be fitted externally between the Rx + (pin 1) and Rx (pin 9) connections of the 15-way remote connector. If used in conjunction with other equipment on a multi-drop system, the bus termination is only required on one equipment, typically the furthest from the master device.
A screened cable, terminated to the back-shell of the remote connector should be used to prevent RF interference from adversely affecting operation. When connecting the cable screen to the back-shell, ideally a full 360ฐ contact should be made.
For short cable runs (up to 10m), a cable containing a twin twisted pair conductor arrangement is ideal. Typical conductor characteristics would be size 24 AWG, screened with an overall tinned copper braid. For cable runs above 10m, an insulated signal return connection should also be made.
2.4.7 Redundancy Interface Connector
This is provided on the rear panel and is a standard 'D' type 9-pin (M).
The redundancy interface is a standard feature of these units and can be easily configured so that the converters communicate with each other for 1:1 and 1:2 redundancy systems or with the Peak redundancy controller for 1:n redundancy systems. The units communicate using the CANBUSฎ interface system.

3. EQUIPMENT OPERATION
The P7000, P7001, P7001D and P7002 models are L-Band based and have additional features for integration with SHF Block converters.
A typical simple Upconverter system incorporating a P7002 could consist of a P7002 connected directly to a remote outdoor Block Up converter. The P7002 powers and controls the Block converter by supplying DC Power, a Locking frequency for the BUC internal oscillator and the correct L-Band input power and frequency. The P7002 monitors the alarm status of the Block converter to give the operator indication of the state of the outdoor unit. A similar simple Downconverter system could also consist of a P7001 being connected to an LNB on the antenna and providing DC Power, a locking frequency for the LNB oscillator and receiving the L-Band signal. In these situations the DC and 10MHz signals can be switched on and off and the frequency on the P7000 unit can be set to include the frequency of the remote Block converter so input output at SHF is possible.

TX and RX configuration
Remote control
Redundancy
Internal fan control
3.3.1 TX Configuration
On this menu you can
Change frequency
Change Gain
Modify SHF settings
Switch TX output on and off
Switch 10MHz on and off
Switch TX DC feed on and off
3.3.1.1 Frequency
Pressing 1 takes you to a screen which shows the full allowable range and gives you a flashing cursor over the frequency. In L-Band a frequency below 1000MHz must start with a zero. If the current number is invalid an out of range message is shown. Press YES/ENTER to change. You can press YES/ENTER at any time in input to leave remaining numbers unchanged.
3.3.1.2 Gain
Pressing 2 takes you to a screen showing current gain. You can enter a number on the keypad directly but if you press UP or DOWN you are in variable mode which increments or decrements the shown value by 0.1dB. The RIGHT and LEFT arrows allows you to highlight the +/- character and UP and DOWN will change the sign. The gain change is instant.
3.3.1.3 SHF
SHF stands for SUPER HIGH FREQUENCY and in this context refers the SHF stage which is following this L-Band unit.
This feature does not change any controls inside the unit but is a convenience to mathematically add the effect of the following converter on the uplink chain.
For a block up or down converter or an LNB the local oscillator should be determined. This is the number which is added in this menu. To apply this value the SHF has to be switched ON
With Peak Communications equipment the following Local Oscillators apply
PBU600, IBU600 C Band Upconverter 4.95GHz
PBU137, IBU137 Ku Band Upconverter 12.80GHz
PBU140, IBU140 Ku Band Upconverter 13.05GHz
PBD725, IBD725 X Band Downconverter 6.25GHz
PBU790, IBU790 X Band Upconverter 6.95GHz
L510 C-Band Downconverter 5.15GHz (inverts spectrum)
L520 Ku Band Downconverter 10.0GHz
L521 Ku Band Downconverter 10.75GHz
L522 Ku Band Downconverter 11.30GHz
Use of this feature allows the user to manipulate the unit to show the overall SYSTEM frequency and output power levels. This is achieved by selecting both the Local Oscillator frequencies of the external SHF Block Upconverter and the Gain/Loss between Upconverter output and antenna. The SHF LO frequency and Gain/Loss are added/subtracted to the L Band output frequency (not if SHF is ON) and power to obtain the SYSTEM output frequency and power level.
Example: If a P7000 Up converter 70MHz unit is connected to a PBU137 the P7000 display can be set to show the actual output frequency at Ku Band. The Block converter calculation in this case is simply the addition of the BUC Local Oscillator value to the L-Band frequency. If the output is set to 1200MHz (1.2GHz) and the LO is 12.80GHz the output is 1.2+12.8=14.0GHz. IF the 12.80 value is entered as an SHF LO and the feature switched on with SHF ON/OFF you will see that any frequency shown on the unit is at Ku Band which also means you would have to input any new frequency at Ku Band.
3.3.1.4 Carrier
You can switch the transmitter/output on or off with this feature by pressing 4 which toggles ON or OFF.
3.3.1.5 10MHz
You can switch the 10MHz on or off with this feature by pressing 5 which toggles ON or OFF
The 10MHz and DC are sent up the L-Band connection to lock and power the outside block converter. Note that it may take a few minutes after switching on power and Reference for the outside unit to stabilise and the alarm to clear.
3.3.1.6 DC
You can switch the DC on or off with this feature by pressing 5 which toggles ON or OFF
The 10MHz and DC are sent up the L-Band connection to lock and power the outside block converter. Note that it may take a few minutes after switching on power and Reference for the outside unit to stabilise and the alarm to clear.
3.3.2 RX configuration
The only addition to the TX configuration is spectrum invert. As previously described the invert spectrum issue only arises when there is a problem with in-band interfering signals. This happens mainly when C-Band LNBs are used with a 5.15GHz LO and spectrum inversion occurs.
The inversion is corrected in a P7000 downconverter by changing the 2nd LO in the unit to make P7000 invert. The LNB inverts and the P7000 inverts it back again. The whole system has then preserved the spectrum.
3.3.3 Remote Control
This screen provides access to all setup parameters for the remote interface.
3.3.3.1 Set remote mode
Pressing 1 will toggle the unit into either local or remote mode.
Note: In remote mode only the redundancy option is available to be configured from the configuration menu via the front panel, if you try to access the configuration menu while in remote the screen shown below will be displayed.
3.3.3.2 Setup RS485
The RS485 bus address can be set by entering in the number using the numeric keypad.

3.3.4.6 List of units on CANBUS
This lists the converters that are connected to the CANBUS.
3.3.4.7 CANBUS for Passive Redundancy Systems
If a simple 1:1 passive redundant system is required, the converter units can still be connected via the CANBUS interface. This will result in the units monitoring each other and the off-line unit un-muting if the on-line unit fails.
As a passive system has no tellback facility (from relay contacts), this normal feature has to be disabled to allow the passive redundant system to function correctly, this is done as follows;
From the HOME menu, press 9 to access the hidden SETUP menu.
Note; This menu and all sub-menus are factory set and it is not recommended that the user changes other parameters within this menu without consulting the factory.

5. REDUNDANCY
The P7000 series of frequency converters interface with the Peak CANBUS redundancy system for 1:1, 1:2 and 1:N redundancy systems.
5.1 1 for 1 Redundancy (switched & passive)
For 1:1 switched redundant operation a pair of P7xxx units is required along with an R1000 for receive applications and for Transmit applications a T1000 is required, for full P7000 transmit and receive applications a RT1000 is available.
In use, the redundancy type on the configure / redundancy menu is set to 1:1 and one unit is set to identifier A and the other to identifier B. The R/T1000 is connected to the rear panel 9 way connector with the supplied cables and the units will self detect and set one unit to online and the other will be set to standby. A changeover will be caused by an alarm detected in the online unit or changeover (keypad 4) being selected, this will result in the configuration of the online unit being taken over by the standby and then the standby will take over the RF path, making itself the online unit.
If a simple 1:1 passive redundant system is required, the converter units can still be connected via the CANBUS interface. This will result in the units monitoring each other and the off-line unit un-muting if the on-line unit fails.
As a passive system has no tellback facility (from relay contacts), this normal feature has to be disabled to allow the passive redundant system to function correctly. To perform this task please refer to redundancy in the equipment operation section.
5.2 1 for 2 Redundancy
For 1:2 switched redundant operation a Trio of P7xxx units is required along with an R2000 for receive applications and for Transmit applications a T2000 is required, for full P7000 transmit and receive applications a RT2000 is available.
In use, the redundancy type on the configure / redundancy menu is set to 1:2 and one unit is set to identifier A and the other to identifier B and the third set to Standby the R/T2000 is connected to the rear panel 9 way connector with the supplied cables and the units will self detect. A changeover will be caused by an alarm detected in an online unit or changeover (keypad 4) being selected, this will result in the configuration of the online unit being taken over by the standby and then the standby will take over the RF path, making itself the online unit. Priority can be set on paths A and B, so that if there is a second failure and this unit is set to a higher priority it will take control of the standby path, if both units are set to priority 1 then this function will be ignored.
5.3 1 for N Redundancy
For 1:3 to1:8 switched redundant operation the RCU1000 series of redundancy units are available, see data sheets for specifications.

6. REMOTE CONTROL
The unit transmits and receives data serially in an asynchronous format using the standard ASCII character set. The serial data consists of message frames composed of the following message characters: STX, BYTE COUNT, DEVICE ADDRESS, INSTRUCTION, BODY, CHECKSUM, ETX. All characters are compulsory except for the message body. The presence of a message body is determined by the message type (INSTRUCTION). The total number of message characters in a message frame may range from a minimum of 6 to a maximum of 255.
The remote control follows the following protocol: (in byte form)
[STX] start of message character #02.
[B] char defining how many characters are in the message including the STX & ETX parts.
[A] Address of unit. Address ranges from ASCII character 001 to 255.
[I] Instruction number.
See List below
[MESSAGE]
Numerous characters from length 0 upwards.
[CHKSUM]
The checksum is used to verify the accuracy of the message frame. The checksum is defined as the summation of all the bytes in the message, beginning with the 3rd byte (DEVICE ADDRESS) and extending through the body of the message, ending with the last byte before the checksum. The total of the bytes is then ANDed with 255 so that the checksum is truncated to a single byte.
[ETX] End of transmission character #03
All message to and from the unit follow the above protocol with a character format of 8 data bits, one stop bit, no parity, baud rate 19200, 9600, 4800, 2400, 1200 or 300. Note that all numeric values are shown as decimal.

Some parts of the message are not applicable for both an up and a down converter eg.:
Spectrum invert is not used on the upconverter but is on the downconverter.
Where in the table it is specified that a particular parameter is not used for that type of converter, that particular parameter in the remote message is filled with xs this allows the control software to be simpler as the message doesnt change from unit to unit.
Instruction 22 (Rx/Tx Reconfiguration Request):
The message body for this message is a truncated form of the Rx/Tx Status Request Reply (instruction 21)
i.e. no information after the SHF Gain I/P power parameter is sent.
Not all parameters have to be set, if the user doesnt wish to change a particular parameter then a number of xs can be sent in the parameters place. Sending such data will make the unit ignore that particular parameter.
xs should also be sent in place of parameters that are not used by that particular unit type.
The unit MUST be in remote mode to allow reconfiguration of parameters via the remote control. Setting the unit in Remote mode can be done either by the front panel or remotely using the following command:

Alarm Log message routines & Remote Interrogation of the Alarms log.
The unit will remember the number of new LOG entries that have been added since the user last requested LOG entry status.
If instruction 30 is sent, it will respond with the number of new LOG items since the last request.
Instruction 36 can be sent to get the list of currently unread LOG items, when there are no more unread LOG items the unit will respond with *!END!*.
Alternatively the user can ask for LOG item [n] using instruction 32.
