The PRS-M30 is composed of one (1) main component, with four (4) internal functional components:

1. The EM, which houses the capacitor, sensors, and controller. These electronics also control the Autonomous Triggering System (ATS) that will deploy the parachute.

2. The non-removable Parachute Pod™, which contains an energetic charge, a push plate, and a folded parachute.

3. The Flight Termination System (FTS) Module (Internal), a module that enables the EM to communicate with the PRS-M30’s Payload Source Development Kit (PSDK) for motor shutoff.

4. The mounting bracket, strap, and mounting screws, which attach the PRS-M30 to the DJI M30/T and allow for easy removal.

First Time Setup:

When the user receives the product, the PRS will come fully assembled and ready for installation. The required hardware for installation will be included in an accessories bag. For first-time installation on a DJI M30/T drone, strap attachment hardware must be installed on both forward arms of the DJI M30/T.

General Use

To use the PRS-M30 for a flight, the DJI M30/T shall be inspected prior to flight. Once configured for flight and installed in the DJI Dock 1 (if applicable), you will be ready to begin. Once the aircraft is in its flight configuration, the AVSS PRS-M30 can be mounted to the DJI M30/T. Once the PRS-M30 is secured to the DJI M30/T as per the Installation instructions, the PRS-M30 will be ready for use. The PRS-M30 will turn on automatically when the DJI M30/T is turned on.

The Manual Triggering Device (MTD) is initiated through the DJI M30/T transmitter using the PSDK onboard interface. The manual trigger function is provided through the PSDK interface and has a dedicated arm icon/button that must be activated before the parachute can be deployed. To perform a manual trigger of the PRS-M30, the system will need to be armed (see the "Status Indications" section for instructions), and the deploy button will need to be held down for three (3) seconds. During flight, the PRS-M30 MTD can only be armed once an altitude of 5 metres (16.4 ft) AGL is achieved, as measured by the onboard barometer.

Any error with the PRS-M30 will be communicated to the user via the DJI M30/T transmitter. During the flight, the PRS-M30 ATS will arm itself only once it has reached the minimum deployable barometric altitude above takeoff. Afterwards, if the DJI M30/T experiences a failure, the ATS detects the failure using a suite of sensors, forces the motors to shut off, and deploys the parachute without the need for pilot input.

Onboard Power

• The PRS-M30 EM is equipped with an independent capacitor to supply power to the PRS-M30 in the event of a power loss from the DJI M30/T.

• The PRS-M30 EM interfaces and charges directly from the DJI M30/T on drone startup.

• If left in unsuitable environments, the system and/or components may be damaged, the warranty shall be void, and the items may not properly function.

The PRS-M30 has been designed to easily integrate with the DJI M30/T. The PRS mounting holes and screws secure the PRS-M30 without interfering with onboard sensors or DJI Dock 1 usage. The system includes an integrated EM to power the PRS and FTS. The FTS is initiated when either the pilot instigates a deployment through the MTD or when the ATS, using the onboard sensors located in the EM, determines that the DJI M30/T has breached the safe flying parameters. Once the FTS is initiated and stops the motors from spinning, the Parachute Pod™ is deployed and will result in the DJI M30/T descending under an inflated parachute.

Firmware updates must be performed when a new version is released by AVSS. Check the AVSS website regularly for firmware updates, and contact AVSS customer support if you have any questions.

Accessing Firmware Updates

Installation Using AVSS Assistant

Upon accessing and downloading the latest firmware file, users can then import the firmware update onto their PRS using the AVSS Assistant. The AVSS Assistant can be downloaded from the AVSS website (usually in a ZIP format file). The current version number of the software will be included in the file name, as shown below.

The AVSS Assistant can then be installed on a local computer by extracting the "setup.exe" file (as indicated below) and following the installation instructions (also indicated below).

Upon completing the installation, users should see the following screen when they open the AVSS Assistant. The red coloring of the charging cord in the "PRS Connect" box (at top left of screen) indicates that there is presently no PRS-M30 attached to the computer. If the PRS-M30 is connected via USB cord to the computer (see second image below), this icon will turn green to indicate a successful connection.

Upon a successful connection between the PRS-M30 and the AVSS Assistant program, the updated firmware file can be imported into the PRS-M30 by first placing the PRS-M30 into "SD Mode".

Once the PRS-M30 is placed into "SD Mode", the PRS-M30 should automatically disconnect from the local computer, which is indicated to the user with a dialog box.

When in "SD Mode", the PRS-M30 acts as a standard USB device, where its file directory is visible as an external connection to the local computer.

To apply the firmware update, simply navigate to the .sfb files (located within the updated firmware's ZIP file) and copy/paste these files into the PRS-M30's main directory.

Upon pasting the firmware update into the PRS-M30's main directory, the user should close the SD card directory window and then cycle the PRS-M30's power by unplugging the PRS-M30 from the computer and then re-plugging it in.

The PRS-M30 will then update the firmware accordingly, which is indicated to the user by the PRS-M30's status LED displaying as white.

Upon successful completion of the firmware update, the PRS-M30 status light will change from white to green. Leave the PRS-M30 connected to the computer and navigate to the "Device Information" tab in AVSS Assistant to verify the current firmware version.

Download Logs

AVSS Assistant also contains a function to download flight logs to a local computer. To initiate this process, click on the “Download Log” button. A new box “Download Log” will appear. In the “Number of Logs” box type the number of the most recent logs that are to be downloaded and click on the “DOWNLOAD” button. The download will always start from the most recent log and work backward.

At this time, the PRS-M30 will disconnect from the AVSS Assistant application and initiate the log recovery and transfer indicated by the blinking blue colour of the PRS LED. This process might take several minutes.

Clearing Error Codes

Error codes will appear on the PRS-M30 whenever a critical error occurs in flight. These error codes will appear in the PSDK display window until they have been cleared. When a critical error shows up, contact AVSS first. After AVSS analyzes the error, if it is safe to do so, you will be advised to manually clear the error.

To clear the error, click on the “Clean Error Code” and click on the “Clean” button.

IMU Calibration From The DJI M30/T Transmitter

To properly calibrate the IMU, the PRS-M30 must be rotated through the six physical orientations, with a minimum of five (5) seconds spent in each orientation. Note that this actually results in seven (7) changes in orientation. The easiest way to accomplish this is simply to rotate the DJI M30/T through each orientation with the PRS-M30T attached, as shown below.

After an additional thirty (30) seconds, a successful calibration will be signaled by the disappearance of the calibration warning from the main screen of either the DJI M30/T transmitter or DJI FlightHub 2. The LED status light will also change to green to indicate normal operations. If a successful calibration is not indicated, restart the DJI M30/T to re-pair the PRS-M30 with the DJI-M30/T.

Compass Calibration From the DJI M30/T Transmitter

Independently, the DJI M30/T may prompt a user that the on-board compass needs to be calibrated. In this case, a user shall simply follow the instructions displayed either on the DJI M30/T transmitter screen or in FlightHub 2. It is recommended that while calibrating the compass, the PRS-M30 be attached to the DJI M30/T to avoid changes to the DJI M30/T's magnetic field readings.

IMU Calibration From AVSS Assistant

It is also possible to calibrate the PRS-M30's IMU by using the "Calibrate Mode" function in AVSS Assistant. To access this feature, click on the “Calibration Mode” button to calibrate the PRS’s sensors. Note that if using this option, there is a 300-second time window to complete the calibration maneuver; otherwise, the calibration is automatically cancelled.
