XLINK-30 is a point-to-point data/video wireless transmitting system designed for industrial UAVs, ground
robots and other data communication applications, featuring 30km long transmission distance.
XLINK-30 integrates the technology of 4G, 5G, WIFI, and adopts OFDM technique and multi-path anti-
interference technology, which has the advantages of long distance transmission, low latency, strong
diffraction performance, and big data bandwidth communications.
A great highlight of XLINK-30 is that it supports multi-node interlinked to form a communication mesh, in
which one node is too far from the ground station to receive signals, it is able to transmit data to its nearest
node, by which data can be sent back to the ground station.

Air/Ground Unit Introduction
XLINK-30 needs to be used in pairs. The selection of antenna is determined by the scenarios that it is applied
to. When used on aircraft, the sky end is referred to as the Air Unit, whereas the ground end is called the
Ground Unit.

Quick Start
UI Conguration
XLINK-30 has different data rates, which needs to be congured as needed.
Step 1
Power on XLINK-30, and link it with PC by Ethernet. Then congure IP Address as shown below:
IP Address：192.168.0.1
Subnet Mask：255.255.255.0
Step 2
Search 192.168.0.9 and enter on browser, next it will show a configuration interface as figure 6.
Refer to the chart below for “NOTE”, click “SUBMIT” after conguration is complete.
Step 3
Reboot to activate the congured value.
Step 4
You need to configure the same bandwidth/data rate value for air and ground unit to ensure a
Attention
If the conguration page fails to load, search 192.168.0.9 and reenter browser (Make sure network
cable is well connected).

Pairing
Step 1
After one unit powers on, the SYNC LED indicator turns green. About 30s later, it starts to blink, which means
it is pairing with the other unit.
Step 2
If two units are powered on and paired, the indicator stops blinking and keeps on.
Step 3
If the pairing is failed, the indicator blinks green, during which the unit is still searching until two
devices are successfully paired.
Possible causes of failed pairing
1. One of the unit is powered off.
2. Beyond transmission distance
3. Strong signal interference
