Product Compliance
Safety
To ensure safety of the operator the PBU2000 series of units have been designed to comply with the following
safety standard;
EN 60950: Safety of information technology equipment, including electrical business machines.
Operation of the equipment in a non standard manner will invalidate compliance to this standard. The
equipment MUST BE OPERATED WITH ITS LID ON AT ALL TIMES. If it is necessary to remove the lid for any
purpose then it is essential that the lid is fitted back correctly before normal operation.
DEPENDANT UPON UNIT TYPE, DANGEROUS VOLTAGES MAY BE PRESENT AROUND THE POWER
SUPPLY AND PRECAUTIONS MUST BE TAKEN.
THE EQUIPMENT IS MEANT TO BE OPERATED BY TRAINED PERSONNEL ONLY.
EMC
The PBU2000 units have been designed to comply with the following standards;
Emissions
EN 55022 Class B: Limits and methods of measurement of radio interference characteristics of Information
Technology Equipment.
Immunity
EN 50082 Part 1: Generic immunity standard, part 1: Domestic, commercial and light industrial environ
ment.
Damage to the chassis, controls or interfaces will invalidate compliance; please contact the factory under
these circumstances for advice on continued operation. Interfaces to the PBU2000 series of units must be
made with suitably screened connectors and double screened coaxial cable. Data cables must be double
screened.

Installation and Operating Handbook
Section 1
Unit Description
The PBU2000 incorporates two fixed block up conversion stages along with microprocessor control and moni
toring of internal functions. Switching between the bands is accomplished via. one of the interfaces. If option
11 is supplied, then both band outputs are available simultaneously.
Remote control is available from the front panel connections, RS232/RS485 and ethernet, as well as via
the local wired interface. The internal oscillator is fed from an internal reference, which can also be locked to an
externally provided 10MHz reference frequency to ensure the system is stable and the changeover from one
PBU2000 converter to another, minimises traffic interruption.
1.1 Specification
Please refer to the PBU2000 datasheet for the current standard performance, or contact technical support for
specific technical enquiries.
1.2 Chassis
The unit is housed in a sealed die cast aluminium box. See Appendix A for the dimensions details.
1.3 Mounting
The unit comes with two mounting options:
Flat surface
Two small brackets are supplied for fixing of the unit to a flat surface. The brackets need to be screwed
to the unit’s underside in the appropriate place.
Pole
A kit to mount the unit to a circular pole is supplied.
See Appendix A for details.

Section 2
Operation
Customer supplied DC at +27V to +36V DC is internally fused to 2 Amp and internally reregulated to supply
required voltages to the RF and supervisory circuitry. A form C summary alarm connection is available for
monitoring the PBU2000 unit via an M&C system.
Attach the feed wire carrying the RF signal to the socket marked ’RF In’. Output of the unit is a NType
socket marked ’RF Out’. Check out all cables for shorts before connecting and ensure the connections are
weatherproofed. DC must not be introduced to the RF input or output connectors.
The selection of the internal band is done via one of the enabled interfaces.
Care must be taken when starting the units from cold, as sufficient time must be allowed for the OCXO
to stabilise before introducing an external reference. A suggested, suitable, time is 5 minutes from cold, if this
warm up period is not allowed for, alarms can occur.

Installation and Operating Handbook
Section 3
Redundancy
This section gives a basic overview of the redundancy system with regards to this PBU2000 unit.
The PBU2000 unit interface with the Peak CAN bus™ redundancy system for 1 for 1, 1 for 2 and 1 for N
redundancy systems.
3.1 1 for 1 Redundancy
For 1 for 1 switched redundant operation, a pair of PBU2000 units are required along with an T1000HR(Ka)
(or equivalent) for redundancy applications. In use, the redundancy type on the PBU2000 units is set to 1 for
1, one unit is set to identifier ’A’ and the other to identifier ’B’. The T1000HR(Ka) units are connected to the
PBU2000 ’redundancy’ connectors with the supplied cables, the units will self detect and automatically set one
unit to online and the other to standby / offline.
When an alarm is detected in the online unit, the this will result in the configuration of the online unit being
adopted by the standby and then the standby will be switched to the RF path, becoming the online unit.
The standby unit can be made to go online by the changeover option via one of the remote interfaces.
3.2 1 for 2 Redundancy
For 2 for 1 switched redundant operation a trio of PBU2000 units are required along with an T2000HR(Ka) (or
equivalent) for redundancy applications. In use, the redundancy type on the PBU2000 units is set to 2+1, one
unit is set to identifier ’A’, the second to identifier ’B’ and the third to ’Standby’. The T2000HR(Ka) units are
connected to the ’redundancy’ connectors with the supplied cables and the units self detect. A changeover will
be caused by an alarm detected in an online unit or changeover, via a remote interface has been initiated, this
will result in the configuration of the online unit being adopted by the standby unit and then the standby will be
switched to the RF path, becoming an online unit. Priority can be set on paths A and B, so that if there is a
second failure the higher priority path will remain operational, if both units are set to priority 1 then this function
will be ignored. A larger priority number equates to a higher priority.
3.3 1 for N Redundancy
For 3+1 to 8+1 switched redundant operation the RCU1000 series of redundancy units are available (see
appropriate data sheet for specification).

Installation and Operating Handbook
Section 4
Remote Control
This section describes the various ways it is possible to monitor and control the PBU2000 unit.
4.1 Serial Communications RS232 / RS485
The PBU2000 unit is capable of being controlled remotely using the P7xxx protocol format as described in
section 4.2, through the RS232 / 485 connection, the baudrate of which is variable and is setup via one of the
remote control interfaces.
PBU2000 Peak Communications Ltd. 7

Installation and Operating Handbook
4.2 P7xxx Protocol
The PBU2000 transmits and receives data serially in an asynchronous format using the ASCII character set
(includes the extended ASCII set). The serial data consists of message frames composed of the following
message characters:
STX, number of bytes, unit address, instruction number, message body, checksum, ETX.
All characters are compulsory except for the message body. The presence of a message body is deter
mined by the message type (instruction number). The total number of message characters in a message frame
may range from a minimum of 6 to a maximum of 255. All messages to and from the unit follow the protocol,
as described in table 4.1, with a character format of 8 data bits, one stop bit, no parity, baud rate selectable.
Note that all numeric values are shown as decimal unless otherwise stated.

Checksum
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, begin
ning with the 3rd byte (Unit 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 trun
cated to a single byte

4.2.1 Device
This group of remote messages allow the user to monitor and control the various modifiable parts for the
PBU2000 unit. In order for the unit to accept changes made via the remote control it must be placed in REMOTE
mode.
If the unit doesn’t have any band attenuation options fitted, then the attenuation sections in these messages
are missing.
