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.
