RLINK
Part 1 Introduction
1.1 Summary
RLINK is a long-distance wireless data link communication module developed by
blicube.LLC, supporting Point to Point and Point to Multipoint. Using two RLINK
modules to form a pair of data links for mutual communication, when one connected to the
device end and the other connected to the computer end. With three or more RLINK
modules, it can be used forPoint to Multipoint.
Based on bulid-in P900 module, RLINK has the characteristics of high transmission power,
high link rate, high receiving sensitivity, etc. The ground-to-air communication distance is
up to 30+KM, the transmitting power can reach 1W, besides the module supports wide
voltage input (5～55V) and high-speed frequency hopping. The module has the operating
temperature range of -40 to 80 degrees, with shell of CNC aviation aluminum alloy
materials.

Part 2 Use Guide
2.1 Interface
The RLINK module has two GH1.25 interfaces, shown in Figure 2 .1, where the left side is
the power supply interface, which is recommended to use the provided circuit board for
power supply, and the right side is a serial interface.
Figure 2.1 The interfaces of RLINK
2.2 Default Parameter
RLINK has been configured when you get it. The default link rate is 115 kbps, the boud
rate of serial interface is 57600, and the default broadcast mode is Point to Point. If you
want to modifythe relevant parameters, please refer to Part 3 for custom configurations.
2.3 Communication
➢Pixhawk Flight Controller
Please connect the RLINK serial interface to controller’s Telem1 or Telem2 interface.
➢Other Devices
Please follow the interface definition to connect the RLINK serial interface to other
device serial interface (RX-TX TX-RX GND-GND), if needed.
2.4 Power Suply
Since output power up to 1W, some controller’s and computer’s interfaces have not the
ability to supply such high power, it is recommended strongly that using a separate battery
to supply power for RLINK forthestability.

2.5 Ground Station
Connect RLINK(the ground end) to computer as a monitor via a data cable, it can be auto
connected when using QGroundControl. While when using Mission Planner as your
ground station, it is necessary to select communication port and baud rate as shown in
figure 2.2 at first, click CONNECTand then wait forthe connection to complete.

Part 3 Configuration
RLINK has been configured at the factory and generally does not require additional
configuration. If you need to modify the parameters, you can customize the configuration
according to the instructions below.
3.1 Enter Configuration Mode
Connect RLINK(the ground end) to the computer via a data cable at first, make sure the
your serial assistant can communicate with RLINK, press and hold the RLINK CONFIG
key with a thimble or other sharp object. The RLINK will enter configuration mode when
the serial assistant pops up theNO CARRIER 0K prompt and then release CONFIG key.
Figure 3.1 Enterconfiguration mode
After entering configuration mode, the configuration can be completed by sending the
relevant parameters via the serial assistant (all with OK after successful configuration).
Noting that every configuration command needs to be followed by a carriage return.
