Product Compliance
Safety
To ensure safety of the operator the TLTR3100 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 TLTR3100 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 TLTR3100 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 TLTR3100 remote mounted Test Loop Translator from Peak Communications are designed to be fully
compatible with a wide range of equipment, to provide a monitor path from the output of the SHF amplifier.
These high grade units are designed to accept the signal at SHF and provide a further conversion to the
appropriate output band.
The TLTR3100 are designed to operate over a wide range of SHF power level inputs. The internal con
struction of the unit is modular which gives some flexibility in accommodating customers’ requirements such as
gain and frequency. The unit is powered from the Power / Alarms / Remote connector (see section 1.4).
The incoming RF is passed to the mixer which is fed with an LO which is in turn referenced from an
internally fitted OCXO. At all stages the components have isolators and attenuators to ensure correct matching
is maintained. The receive band signal is then passed out to the RF Out connector with no filtering unless this
has been specified.
The TLTR3100 units are not fitted with amplifiers as standard and have a through loss of 20dB nominal.
Maximum input power with no damage is standard at +15dBm with a non compressed signal level of above
5dB nominal.
The TLTR3100 has an electronically variable KaBand attenuator, with a range of 0  30 dB, and a step
size of 0.125 dB.
1.1 Specification
Please refer to the TLTR3100 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.

Operation
Attach the feed wire carrying the RF signal to the socket marked ’RF In’. Output of the unit is a KType socket
marked ’RF Out’. Check out all cables for shorts before connecting and ensure the connections are weather
proofed. DC must not be introduced to the RF input or output connectors.

Section 3
Remote Control
This section describes the various ways it is possible to monitor and control the TLTR3100 unit.
3.1 Serial Communications RS232 / RS485
The TLTR3100 unit is capable of being controlled remotely using the P7xxx protocol format as described in
section 3.2, through the RS232 / 485 connection, the baudrate of which is variable and is setup via one of the
remote control interfaces.
TLTR3100 Peak Communications Ltd. 5

Installation and Operating Handbook
3.2 P7xxx Protocol
The TLTR3100 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 3.1, 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
