Instrument Care and Safety Information
Please read the whole of this section before using your ViaLiteHD product. It contains important safety
information and will enable you to get the most from your Fibre Optic link.
Electrical Safety
The ViaLiteHD enclosure is a Safety Class 1 product (having metal chassis directly
connected to earth via the power cable).
When operating the equipment note the following precautions:
Hazardous voltages exist within the equipment.
There are no user serviceable modules inside.
There are replaceable fuses inside the casing. Replacement should only be carried out
by a PPM technician.
The chassis earth stud SHOULD be connected to the safety earth.
When using a 2 pin power supply cable the chassis earth stud MUST be connected to
the safety earth.
The ViaLiteHD Power Supply Modules do not have an isolating switch on the mains
voltage inlet. For this reason, the ViaLiteHD chassis MUST be installed within easy
reach of a clearly labelled dual pole mains isolation switch, which supplies the
equipment.
PSU modules are fused on the mains live feed only. A second fuse should be used for
the neutral connection where the polarity of the connectors can be reversed; rating
should match those given in section 2.13.
ESD Precautions Precautions for handling electro-static sensitive devices should be observed when
handling all ViaLite modules. Technicians should ensure that they use effective personal
grounding (i.e. ESD wrist strap etc.) when servicing the equipment. Any equipment or
tools used should be grounded to prevent static charge build-up. Good practice should be
observed at all times. For reference see relevant standards.
EN 61340-5-1, “Protection of Electronic Devices from Electrostatic Phenomena – General
Requirements”

1 Introduction
The Outdoor Enclosure type MINI (ODE-MINI), is a cost-effective weatherproof enclosure for ViaLiteHD
systems and associated hardware. It is intended to service the requirements of most GPS timing and satellite
communication systems though can be configured to suit a wide range of other applications.
The ODE-MINI system is comprised of the following key parts:
IP-65 rated external enclosure fitted with:
Dual power supplies (redundancy or power sharing)
Capacity for up to two ViaLiteHD OEM modules with front panel connections
Termination of input power cable (inside the supplied quick release latching connector)
Patch box for termination of optical cable (various quad fibre cable lengths available)
Connectorised RF inputs / outputs.
It has a wide range of optional accessories including:
Lightning suppressor(s)
Optical cable
Wall or pole mount fixings.
ViaLiteHD RF Fibre Optic Links (FOLs) are a family of fibre optically coupled link systems designed for the
transmission of RF analogue signals over long distances for the communications market.
ViaLite is a product brand manufactured by Pulse Power and Measurement Ltd (PPM).
ViaLite Communications is a division of Pulse Power and Measurement Ltd (PPM).
1.1 Typical deployment
A typical system operates as follows.
The ODE-MINI would house a set of FOL TX modules, in a remote outdoor location connected to antenna
equipment. Antenna electrical signals are input to the transmitter modules, which contain RF signal
conditioning and laser control circuitry. The modules modulate the intensity of a beam of light with the RF
signal for optical transport over a fibre optic cable.
The light travels through the optical fibres to corresponding receiver modules. The distance between
transmitter and receiver can range from 1 m to 100 km; distance in excess of 100 km can be achieved with
more complex optical transport systems, depending on the system specified.
The receiver module converts the modulated light back into an electrical signal, which is available at its
output.
1.2 ViaLiteHD compatibility
The RF and optical interfaces are compatible with all ViaLiteHD Blue modules.
Contact ViaLite Communications or your local ViaLite agent for more details.
1.3 Care of fibre optic connectors
When the fibre optic cables are not connected, it is essential that the cable and equipment connectors are
protected by the dust caps provided with the system. Failure to do so may result in damage to the fibre ends,
which are critical to the system performance. Please refer to section 1.4 for fibre optic cable handling details.

OUTDOOR ENCLOSURE TYPE MINI HANDBOOK

1.4 Fibre optic cable & connectors
Connector and cable types
All ViaLiteHD RF modules use singlemode (9µm/125µm) cable terminated in a range of optical connectors
detailed below. Cross-site fibre optic cables are available from ViaLite Communications as either standard
patch leads or heavy-duty multicore cables.
Warning!
Angle polished (APC) and standard (PC) connector must not be confused. The two
connector types are not interchangeable and mating one with the other will damage both the
cable and the module connectors.
The specification of optical connector is critical to the performance of the complete fibre optic
link. System performance can only be guaranteed with fibre optic cables and connectors
supplied by ViaLite Communications. When FC/APC connectors are specified they must
be “narrow key width”.
Connecting and disconnecting
Before connecting optical fibres to the module or to each other, ensure that the mating connectors are clean
(see below).
Cleaning optical connectors, cleaning before every use
Optical connectors MUST be cleaned before use, even where they have been protected with dust caps.
A large percentage of performance issues can be attributed to dirty fibres.
For more details please read the cleaning instruction which accompanies the connector cleaning kit.
Cleaning optical connectors, high levels of contamination
If there are performance issues that are not resolved by basic cleaning in section 1.4.3, then the following
procedure should be used. If the level of contamination is high it will be necessary to repeat this procedure.
Cleaning items required
Lint free fibre cleaning tissues and/or cleaning sticks (normal cosmetic tissues produce dust and are not
acceptable).
Reagent grade Iso Propyl Alcohol (IPA).
Air duster or filtered compressed air line.
Cable Connector Cleaning
Dampen a patch of cleaning tissue with IPA and clean all surfaces of the plug ferrule.
Using a dry cleaning tissue, dry the ferrule and clean the end face.
Using the air duster, blow away any residue from the end of the connector.
Peel the plastic cover from an unused “N”
cleaning pad.
Hold the connector between your thumb
and forefinger
Clean the connector using firm pressure by
swiping in a pendulum motion through each
segment of the “N” shape, following the
diagram
Do not swipe over the same space twice.

OUTDOOR ENCLOSURE TYPE MINI HANDBOOK
6
Module Female Receptacle Cleaning (only recommended if problems are being experienced)
Either use an optical cleaning stick or twist a cleaning tissue to form a stiff probe, moisten either with IPA.
Gently push the probe into the receptacle and twist around several times to dislodge any dirt.
Repeat the above process with a dry tissue.
Using the air duster, blow away any residue from the receptacle.
Important Notes
IPA is flammable. Follow appropriate precautions / local guidelines when handling and storing.
IPA can be harmful if spilt on skin. Use appropriate protection when handling.
It should only be necessary to clean the female receptacles on the modules if problems are being
experienced.
Never inspect an optical fibre or connector with the naked eye or an instrument unless you
are convinced that there is no optical radiation being emitted by the fibre. Remove all
power sources to all modules, and completely disconnect the optical fibres.
SC/APC Connectors
To connect SC/APC optical connectors follow these steps:
Remove the plug protective cover.
Align the connector keyway slot in the adaptor to the key of the plug.
Gently push the plug-into the adapter until a click is heard and the connector locks.
To disconnect follow these steps:
Grip the body of the plug and gently pull the plug from the adaptor, replace the protective cover.
Only connect SC/APC cable to SC/APC.
Minimum bend radius
Because optical fibre is made of glass, it is important not to subject it to excessive stress. For this reason,
each type of cable has a minimum bend radius (MBR) specification, beyond which the cable cannot be bent
without permanent damage occurring.
The minimum bend radius (MBR) of fibre optic cable fitted to ViaLite modules is 50mm. MBR specifications
for ViaLite Communications supplied fibre optic cables are given in the ViaLiteHD RF Link Handbook.

2 Setting up the ODE-MINI
This section describes the connections between your ODE-MINI and external systems and steps that must be
taken to set it up. Your ODE-MINI should be delivered preconfigured and ready, but will require connections
to external services. This will generally require that you take the following steps:
Mount the ODE-MINI and the patch box in the required locations
Terminate the fibre connections within the patch box
Terminate the RF connections at the ODE-MINI base plate
Terminate the input power at the ODE-MINI base plate.
2.1 ODE-MINI external features
The ODE-MINI is closed via four M4 screws; this can be torqued with a 4mm AF hexagonal key. The rear
provides fixing points for mounting the unit to either a wall mount plate or a pole mounting kit. The unit may
also be fitted with a solar shield; this is advisable for any application where there may be significant solar gain.

Humidity control/ventilator gland
The enclosure incorporates a side mounted vent that allows the air pressure inside the enclosure to equalise
with the external environment. Furthermore, it allows excess humidity to leave the enclosure whilst preventing
moisture from entering.
Upon installation and sealing of the enclosure, this vent facilitates a stable low pressure differential to ease
stress on the seals and a natural continual drying of the internal humidity for improved reliability of the
electronics.

2.5 Antennas
A range of GPS antennas are available that are compatible with the ODE-MINI. A selection are shown below.
70005 GPS marine active antenna, 5 dBi plus 28 dB amplifier.
70040 GPS active antenna, 3.5 dBi plus 50 dB amplifier.
2.6 Termination of RF Connections
The main enclosure terminates the RF input/output via N-Type female connections located on its baseplate.
N-Type connectors are available in both 50 and 75 ohm variants. 50 ohm N-Types are used in the majority of
applications, though if 75 ohm connectors are fitted, you MUST ensure that both halves are the same
impedance; mating dissimilar connectors will cause permanent physical damage.
RF inputs and outputs should not be exposed to DC voltage levels in excess of ±36 V.
Absolute maximum no damage RF input level is nominally +13 dBm
(some units may tolerate more power, please see module handbook).
Some transmitter modules are pre-configured to have a DC voltage present on the RF input connector to
power low noise amplifiers and similar equipment. All receiver modules will create up to 2 V peak DC
transient from the RF output at start up into a 50Ω load (approximately 5 V into a 1 MΩ load). This may cause
failure in some very sensitive equipment.

Female Black, Yellow 2P+E Power Connector Mains 20A Socket Cable Mount, 250 V ac
Polyamide.
This equipment must be earthed in accordance with the local codes. Incomplete or incorrect earthing will
cause a safety hazard. The incoming power cable must have a diameter between 6 and 12 mm to be correctly
retained by the connector. The electrical conductor cross sectional area should be within the range of 1 - 2.5
mm2to ensure sufficient current handling of up to 2 Amps. This equipment is not intended for direct
connection to building installation wiring; ensure connection is via an overcurrent protection breaker and/or
residual current device.
Ensure that the power cable is isolated and no power is present during installation.
Follow the steps below to fit the power connector

ODE-MINI, internal features
The internals of the ODE-MINI are presented as follows:
The top section houses the dual power supplies which sit directly above the power distribution bar. Within this
bar are the power sharing electronics to support the redundant power supply feature and the LNB voltage
generator. LEDs indicating the presence and state of each PSU module are presented to aid both installation
and diagnostic processes. A replaceable fuse is present also.
The main module bay, supports up to 2 ViaLiteHD blue or yellow modules or a single purple module.
Standard layout is TX in slot 1 and RX in slot 2. Item 5 in the list above - Module 1 - is usually TX, and item 6
- Module 2 –is usually RX.
Connect RJ45 and interrogate the site controller to confirm part numbers, serial numbers and settings (gain
etc.).
If using a standard ODE-MINI at both ends of the link, you must ensure your Neutrik cable is a crossover, with
the module ports 1 and 2 crossed over and the SFP ports 1 and 2 crossed over.
2.9 LNB Voltage selection
ViaLiteHD Blue modules have the option to pass a voltage via the internal bias T to any connected RF
equipment (e.g. LNBs).
There are options for (NONE), (Fixed 12V), (Fixed 48V) and customer variable (13V, 15V, 18V or 24V) as

An option for 13V output is also available. This can be partnered with the customer selectable voltage (usually
18 V) to power LNBs with voltage defining polarisation switching. The user can then operate two optical links,
one serving each polarisation from a dual LNB.
LNB Customer variable voltage source
The ODE-MINI incorporates an optional, selectable voltage power supply to facilitate antenna LNB powering if
required.
The user must ensure that the power requirements of their LNB(s) do not exceed the ODE-MINI power
capacity which is labelled internally. To drive external equipment with very high power requirements (e.g. a
BUC) the option for dual redundant power supplies can be substituted for a dedicated supply to provide this
function which bypasses this selector. See next section (ODE-MINI power supplies) for details.
The ODE-MINI LNB voltage setting is factory set to match the customer requirement prior to shipping, but
should it need changing, the following procedure should be performed:
Power down the enclosure by switching both power supplies off.
Using a 2.5 mm flat blade screwdriver or small crosshead, adjust the 4 position switch such that its arrow
head is pointing toward the desired voltage.
Re-establish power by switching on the power supply switches.

2.10 High voltage or high power LNB/BUC supply options
When the on-board variable supply is not suitable for an application, the option for using a dedicated PSU can
be considered.
Power supply redundancy for the ODE-MINI is then no longer possible, but the option for 12V or 48V at up to
15 W is possible or even 25 W for temperature environments < 45 Degrees Centigrade.
Please consult with the factory for this arrangement as it will be built to order and there are no customer re-
configurable options.
2.11 ODE-MINI power supplies
The ODE-MINI is equipped with internal power supply modules. They are generally used in a dual redundant
configuration with identical modules in the left hand (LH) and right hand (RH) positions. It can optionally be
equipped with either just a single main PSU module (LH) or with a main PSU (LH) and LNA/BUC PSU (RH).
The voltage inputs for the various power supplies’options have the following requirements.
AC input wide range 88 –264 VAC 47-63 Hz Power supply: LPS-MINI
DC input 18-75 VDC Power supply: LPS-MINI-DC
2.12 Replacement of Power Supply Modules
The outdoor housing can be fitted with either one or two power supply modules, the latter provides dual
redundant power supply protection for the housing. The power supplies come pre-installed in the outdoor
housing. Should it be necessary to replace a power supply module, the procedure is as follows:
First isolate the unit from the mains power inlet by switching the power isolation switch adjacent to the
unit OFF.
Disconnect the electrical connections between the power supply module and the switch bar.
Undo the two nuts holding the power supply unit in place. Retain the nuts to refit the new power supply.
Locate the new module on the studs on the rear plate. Replace the nuts to hold the power supply
module in place.
Reconnect the electrical connector between the power supply module and the switch bar.
Apply power by switching the power isolation switch ON.
