2 Overview
The SkyHopper PRO offers a bi-directional Data Link specically designed for commercial and industrial drones, and provides the
best solution for eet management and autonomous UAV systems. By employing leading wireless technologies, SkyHopper PRO
delivers long range and Non-Line of Sight (N-LOS) communication that supports broadcast, multicast and unicast transmission
modes.
SkyHopper PRO supports Point-to-Point and Point-to-Multipoint communication, thereby enabling various modes of operation
such as communication for multi-drone operations and drone communication to multiple ground units and viewers (receivers).
An additional benet of your SkyHopper PRO is that it offers Control, Telemetry and Payload all in one RF channel. No need for
separate solutions for each, no need for excess items to weigh down your drone.

2.1. Network Topologies and Applications
2.1.1. Point-to-Point (PTP)
A Point-to-Point system includes 2 units, with the bandwidth ratio between the two units congurable according to the ap-
plication. It can be symmetric when a full duplex communication is required (50% to each unit) or asymmetric up to 10% to
one unit (Controller or Remote Unit) and 90% to the other unit (i.e. drone/robot that transmits video to the ground/controller
unit and that controls the camera).
Example for an asymmetric link: 6Mbps conguration, where 10% of available BW is allocated for uplink and 90% is allocat-
ed for downlink.
Downlink 10% = 0.6 Mbps
Downlink 90% = 5.4 Mbps
Uplink 10% = 0.6 Mbps
Uplink 90% = 5.4 Mbps

2.3. Packets supported by the SkyHopper PRO network
The SkyHopper PRO physical link supports Ethernet (IEEE 802.3) which includes:
1. Ethernet, VLAN Services, VPN and any other Protocol over IP.
2. Real-time applications using RT Protocols such as: Voice, Video, Data
3. Broadcast, Multicast, Unicast
Any Ethernet packet received by the unit’s Ethernet port is encapsulated internally with a standard frame for transmitting via
the Data Link to the remote unit. The remote unit recovers the original Ethernet packet and forwards it to the Ethernet port.
►NOTE – The unit is similar to Ethernet layer 1 (physical layer), which makes integration with your
equipment nothing more than connecting the Ethernet cable.

6 TDMA
Time Division Multiple Access(TDMA) is achannel access methodfor shared medium networks. It allows several units to share
the samefrequency channelby dividing the signal into different time slots. The units transmit and receive on the same frequency
in a synchronized manner. Every unit transmits in its own dedicated time slots. On the other time slots said unit receives the trans-
mission sent by the other units that are members of the same network (which are also transmitting on their own dedicated slots).
TDMA requires a synchronization system. The system is synchronized internally, externally or via GPS (synchronization varies
between topologies and method used).
The SkyHopper PRO unit uses TDMA regardless of the application type, PTP or PTMP.
7 PTP (Point-to-Point)
A PTP network is a radio link between 2 SkyHopper PRO units. The conguration (frequency and prole) of both units must be
the same with only one difference - one unit is congured as a Remote Unit while the other unit is congured as a Controller Unit.
The Remote Unit works with its internal clock and synchronizes the Controller Unit. After power-up, the Remote Unit starts trans-
mitting regardless of link status. The Controller Unit however, does not transmit and stays in Rx mode, trying to acquire synchroni-
zation by nding a preamble (synchronization pattern). As soon as the Controller Unit recognizes the pattern, it starts to transmit
according to its allocated time slot.
The transmission bandwidth ratio is predened as part of the prole conguration. It can be symmetric when full duplex commu-
nications are required (50% to each unit) or asymmetric up to 10% to one unit (remote or controller) and 90% to the other unit.
Downlink 10% = 0.6 Mbps

7. 1. PTP Link Step-by-Step Conguration
In order to build a PTP link, two SkyHopper PRO units are required. One unit acts as a remote unit, while the other as a
controller unit.
1. Connect antennas to RF1 and RF2 connectors, and power up the unit.
! CAUTION – Powering up a unit without connecting the antennas can cause irreparable damage to the unit.
2. Connect the unit to a PC using a standard Ethernet Cat 5 cable.

12
3. Set static IP in the 192.168.131.xxx subnet (For more information, see the Web GUI Instructional Manual).
4. Using the Web GUI: Open a web browser installed on your PC / laptop (Chrome, Firefox, Internet Explorer, etc.) and
input in the address line: 192.168.131.241. That should connect you to the Web GUI interface, as shown on Figure 6:
Figure 6: Web GUI main screen
5. To change the frequency to the required frequency, click on “Advanced Conguration”(third tab on the left corner) and on the
“Frequency” line and write the desired frequency within the frequency range set in your unit.
6. Set the prole as required (RF bandwidth, bitrate and ratio) and click on the “Apply” button as shown on Figure 7. The
unit will reboot.
7. Repeat stages 1-4 with the 2nd unit.
Figure 7: Web GUI “Advanced conguration” screen

7.2. SkyHopper PRO LED indicator
By following the LED on the unit, the power and link status can be monitored. It is described as follows:
1) ACTV LED:
A) Off – Power Down
B) On - Booting Up
C) Slow Blinking – Remote unit is transmitting, controller unit receiving (P2P search)
D) Fast Blinking – Air Link is up
1) DATA LED
A) Off – No Ethernet detected
B) On – Ethernet Cable is connected to a working device on host – No Data
C) Slow Blink – Error (synced to ACTV LED)
D) Fast Blink –Tx & Rx Air Traffic active
Should there be an error in your SkyHopper PRO unit, both the ACTV and DATA LEDs will be simultaneously slow blinking.
Link status, CINR, RSSI, throughput and unit log information is available in the Web GUI, which can be found online at www.

8.2. Connecting the Antennas
Antennas for installation vary in size, shape, requirements and mounting methods.The antennas should be as close to the
SkyHopper PRO as possible and can be connected to it directly.
Cables should be chosen according to their attenuation (lower attenuation gives better results) and exibility (according
to the path they pass through). Each cable should have an MMCX Male connector on the SkyHopper PRO end, and a
connector matching the antenna’s connector on the other.
8.3. Connecting the Power
SkyHopper PRO has a dual power feed enabling hot-swap battery replacement during operation.
! CAUTION – Powering up a SkyHopper PRO without connecting the antennas can cause irrepairable
damage to the unit.

Appendix D – Setting up a Pixhawk based system
In this section we will describe how to setup a network for a drone using a Pixhawk ight controller.
The Pixhawk ight controller uses a UART interface and runs the MAVlink protocol over it. SkyHopper PRO has an RS232 inter-
face which is similar in its word structure to RS232 but there is a difference in the voltage levels.
D. 1. SkyHopper Setup
The rst stage is to setup the SkyHopper link to enable the UART interface on the link. The conguration should be setup on
both units (Remote/Aerial and Controller/Ground).

2. Enable the UART and choose UART-to-UART
3. Setup the Baud rate to 57600
4. Choose protocol C
5. Reboot the unit
6. Repeat on both Remote and Controller units
D.2. Physical Connection
After the units are congured, the Pixhawk ight controller should be connected to the unit.
On the remote (Aerial) unit Use the Pixhawk adapter accessory which can be purchased on our website and connect it to
the serial cable provided with the SkyHopper PRO unit. Connect the adapter to the Pixhawk ight controller and the serial
cable to the unit.
On the controller (Ground) unit, connect the D-Type/9-pin accessory adapter to the serial cable supplied and connect the
cable to the unit. If the Tablet/PC has a serial port, connect it directly, if not, a USB-RS232 adapter should be used.
D.3. UART to Ethernet
There is an option to congure the system to work with a UART-to-Ethernet conguration, which eliminates the use of the
serial cable on the Ground Unit.
Please refer to the UART-to-Ethernet Connection Guide online at www.skyhopper.biz/prosupport.
