General description
LiteSync is designed to supply power to devices on standard Power over Ethernet (PoE).
It is equipped with 2 integrated Gigabit Ethernet ports and can acquire the synchronization pulse via integrated GPS and Sync
Input port.
On the front there is a group of 3 LED that indicates the status of the unit and the synchronization presence.
It has 2 pairs of ports: injectors to power and synchronize devices in the lower part, connectors to connect the LAN network
in the upper part. Each single door has its own status LED.
On the front of the unit there are slots for inserting the GigaKey keys that allow you to select the output pin of the PoE port
without the use of microswitches in order to provide PoE to a wide range of devices.
LiteSync can be powered redundantly via two connectors. Each connector has its own power supply LED indicator. On the
back is the grounding terminal.
The Sync input port allows you to acquire the synchronization pulse from an external source through the RJ12 connector. You
can select the sync source (AUX: Sync input; GPS: GPS Antenna) through the source selector.
An external GPS antenna can be connected to this connector which will be used to generate synchronous pulses.

LiteSync features
Simple installation
The LiteSync unit is ready to be installed. Just insert the GigaKey, connect the GPS antenna (if synchronization is required) and
power the device.
Cambium Networks synchronization
LiteSync can insert into the PoE ports the sync pulse used by Cambium Networks devices to sync the transmission.
Manages any type of PoE
Each port can be configured to handle a different type of injection map, with or without sync pulse. The configuration of the
power supply pinout is simple and does not require any IT skills: just insert the specific electronic GigaKey and the port is
configured.
Certified partners
LiteSync is a standard PoE injector capable to power any device in a range from 24V to 56V.
To offer increasingly heterogeneous and compatible solutions, we have also certified our product with the main vendors in
the TLC world, such as Cambium Networks, Ceragon and Intracom Telecom, who have tested their solutions both in the
laboratory and in the field.
Multiple and redundant temporization source
LiteSync has a built-in GPS receiver and can acts as master or slave with other units such us GigaSync or CMM5 (of Cambium
Networks) through the Sync Input port.
More power
Up to 3A (145W@48V) per port.
Short circuit and overvoltage protection
Connected devices are protected against short circuits, electrostatic surges and electric shocks. The combination of different
types of arresters maximizes efficiency and reduces the action time.
Galvanic isolation
Galvanic isolation protects circuits and people from overvoltage between the input side and the output side. This results in
the best protection for your devices and for you.
Half unit rack mount
LiteSync is 1U tall, can be installed in a rack using the half unit flange or paired with another LiteSync.

IMPORTANT NOTES:
 (*) The typical current of 3 A per port can be achieved if the PoE configuration chosen to power a device is through
one of the GigaKey: GS-K-AB or GS-K-9.S because they both use all four pairs of conductors for power. If instead we
use the other GigaKeys: GS-K-B or GS-K-BR, the typical current per port will be 1.5A2.
 (*) Although the typical value indicates that the current of 3A can flow continuously and indefinitely, this value should
not be exceeded.

Before turning on the device it is advisable to connect the ground terminal, fix the chassis to the cabinet or to the wall, insert
the chosen GigaKey keys and connect the signal cables, in particular:
• Ethernet cables.
• Coaxial cable and GPS antenna or cable with RJ12 connector (in case you need to acquire the sync pulse).
• Wire up the power supply (optional standalone power supply ACDC-48 or ACDC-24 supplied by 9dot).
• Connect the power supply pins of the power supply paying attention to the polarity adopted.
• Connect the power supply to the electricity.
These cables are not supplied with LiteSync and must be purchased separately3.

Blocks diagram
The electronic design shows the presence of two main structures:
 (•) a CPU guarantees the correct operation of all the basic electronics and performs the voltage and current
measurement
 (•) the power components. The isolated converter is powered via one or both pairs of input terminals
The following is a schematic detail of the LiteSync design structure.
The power inputs, connectable through two redundant connectors, they have the negative pole interconnected and no
conversion is made to the applied voltage, so it will be the same voltage that comes out of the PoE port.
In this way it is possible to connect several voltages simultaneously, for example:
 Input power 1

48V
 Input power 2

Input power
The technical information of the input power is detailed below:
Input voltage Self-consumption Max load
Main input power +/- 24 - 60V DC 4W 360W
Table 3 - Voltage range, self-consumption and maximum load of the input power
To turn on the device it must be powered via redundant terminals on the front (optional standalone power supply ACDC-48
or ACDC-24 provided by 9dot).
The main input has an isolated DCDC converter that powers the CPU. In this way, maximum immunity from voltage surges
present on the power supply lines is guaranteed.
The main input admits polarity inversion, that is, a negative voltage can be connected to its terminals without problems.
IMPORTANT NOTES:
• The negative poles of the power connectors are directly connected. The reverse polarity protection does not protect
the device in the event that the two negative poles are connected to voltages not suitable for being short-circuited
together.
• The redundant power supply terminals can be used simultaneously, even with different voltages. In the case of two
different power supplies (for example 48V and 24V), LiteSync will power the output devices with the highest active
voltage.
Special case -48V
If you have a voltage of -48V (as often happens in some telecommunication systems), just connect the 0V cable to the positive
(+) terminal and the -48V to the negative (-) terminal according to the indications on the LiteSync silk-screen printing.
Output power
The main function of the PoE injector of this device is to allow the powering of other equipment on the network. LiteSync is a
passive injector.
IMPORTANT NOTES: Unlike active PoE, passive PoE does not use any protocol to determine the type of device to be powered;
it simply applies a type of voltage to its port without identifying which type of PoE standard or supply voltage the connected
load is compatible with. Using an unsuitable voltage and / or wrong pin out can cause irreparable damage to the powered
device.
It is possible to power a wide range of devices that accept different voltages as this cartridge essentially replicates the voltage
from the power terminals to the PoE output ports without applying any conversion.
This offers great versatility when it comes to connecting several PoE devices in the same infrastructure as each cartridge can
be powered at a different voltage than the rest.
In addition to supporting different voltages, the PoE Injector has the possibility to select the pin out of the PoE output ports,
by inserting a simple key, called GigaKey, thus allowing it to power a wide range of devices on the market.
To find out if your PoE device can be powered via LiteSync, just check the pin out that the GigaKey allows you to select and see
if it matches the input pin out of your equipment.4.

See the "GigaKey" section

13
LITESYNC MANUAL VER. 2 REV. 0
Special case -48V
There are facilities that require -48V power over the network, this option is perfectly feasible with LiteSync. We simply have
to connect the -48V to the input
5
and then choose the correct GigaKey in order to get -48V on the PoE ports based on the input
pin out of the devices we want to connect.
Protection
LiteSync detects the applied load value in real time. In the event of a sudden overload or short circuit, the protection intervenes
and interrupts the supply of the output voltage for 10 seconds. At the end of the period of inactivity, the voltage is supplied
again. During the period of suspension due to overload, the LED of the corresponding port flashes red.
On each port there are double phase surge arresters TVS (Transient Voltage Suppression) and GDT (Gas Discharge Tube).
Synchronization pulse
LiteSync offers the possibility to inject, through the same PoE port, the synchronization pulses compatible with the proprietary
Cambium Sync method that allows you to work with Gigabit Ethernet (1000BaseT). This means that the injector will allow
you to take advantage of the synchronization
6
of network devices compatible with the method mentioned above.
GigaKey
This is the generic name which identify the selection keys of the output pinout of each PoE port.
The GigaKey has been designed to avoid handling with the microswitches or jumpers that normally perform this function, but
are subject to errors. This simplifies selection, executable simply by inserting the chosen key into the slot corresponding to
the PoE port.
If desired, you can select a different GigaKey for each PoE port on the same cartridge.
At the moment, 4 different GigaKey have been developed that allow a wide range of compatibility between devices on the
market. They are easy to identify by their code and different colors.

(*) These are just some of the devices that can work with LiteSync. The list is very long, if you want to know if your equipment can connect to LiteSync, do not
hesitate to contact us.
Pay attention to the direction of insertion of the GigaKeys in the slots: the correct position is with the screen printing facing
upwards.
Synchronization
Many telecommunication networks require synchronization precision for their correct operation and, therefore, avoid self-
interference and reduce noise generated by the network. In this way, frequencies can also be reused and spectrally efficient.
This is possible to achieve if co-located devices are synchronized.
To synchronize the equipment, you must have a standard signal that serves as a reference to accurately determine the
corresponding data send and receive slots. This signal is known as a sync pulse and it will allow all synchronized devices to
send and receive data in the same period of time: uplink (sending data) and downlink (receiving data) so that when one
receives information, none of the others are sending.
The reference signal to generate the synchronization pulse, also known as "1PPS" or "pulse per second", can be obtained in
different ways:
 Through the external GPS antenna
 Through the LiteSync “Sync Input” port, connecting:
o “Sync output” port of GigaSync
o Cambium Networks uGPS
o Cambium Networks cnPulse
o Cambium Networks CMM5
With this sync pulse, the LiteSync can perfectly replicate the Cambium Networks sync mode as described in the following
table:

(§) It depends on the source of synchronization that provides the pulse.
GPS antenna
The external antenna must be connected to the N-type female connector that is installed on the front of the LiteSync and
requires a good view of the sky. It does not need to be mounted at the highest point of the tower.

The antenna connected to the LiteSync must be active; the GPS chip integrated in the LiteSync supplies a 3.3V DC voltage on
the N connector, to power the filters and amplifiers inside the antenna; for the same reason it is essential, to ensure the
operation of the GPS system, that the RF protections inserted between LiteSync and GPS antenna allow the power to pass
through (DC Pass).
