Page 7: Installation
Parachute Manual DRS-M210-V2 5 Installation Unmount all propellors and detach all batteries and other power supplies before starting the installation! Mounted propellors may cause any injuries or damages. It is mandatory to verify the correct operation with an assembly test right after the installation! See chapter 5.6 Assembly test for details. -

Page 9: Mount The Cords
Parachute Manual DRS-M210-V2 Mount the cords Make sure the drone is in a stable upside position. Select one of the front arms of the UAV. Mount one Parachute cord to the arm and pull it around close to the hinge. Thread one end of the cord through the other end’s loop. - Page 10 Parachute Manual DRS-M210-V2 Now fasten the Hook and loop fastener. Take both Parachute cords and thread the ends through the central hole in the Cord box lid. Then push the lid downwards. Thread the open ends of both Parachute cords through the Hook’s...

Parachute Manual DRS-M210-V2 Configure the M210-V2 5.4.1 Configure Onboard SDK in DJI Assistant Application Onboard SDK is used to switch off the UAV motors before the parachute is deployed. • Connect the UAV with a PC and use DJI Assistant 2 to configure the output (see DJI M210 user manual for details). -
Page 13: Configure Pwm Signal In Dji Pilot App
Parachute Manual DRS-M210-V2 5.4.2 Configure PWM signal in DJI Pilot App The deployment can be triggered manually with a PWM signal which is generated by the UAV. Therefore, you must configure the PWM output before use. • Enter the settings in the DJI Pilot app (top right corner;... - Page 14 Parachute Manual DRS-M210-V2 • Enable “Power Supply Port”, “OSDK Communication Port”, and “Time Sync and PWM” settings. Then enter the settings for “Port 4” • Switch to PWM mode, set the duty ratio to 50‰ (= 5%) and the frequency to 50 Hz.

Page 15: Onboard Sdk Activation
Caution: If the activation is skipped or if it fails, then the DRS cannot turn off the motors and the parachute or the cords can get tangled up in the propellors when the parachute is deployed. It is therefore absolutely inevitable to verify that the motors stop at the assembly test. - Page 16 • Turn on the UAV and perform the usual takeoff procedure until the motors are spinning but without taking off. • Verify the correct status of the DRS by observing the LED and the buzzer signals. The DRS should be in the ARMED MANUAL state.

Parachute Manual DRS-M210-V2 Loading and unloading the parachute First open the release mechanism of the Container, which is the small shutter at the bottom. The easiest way to do so is to get underneath the shutter using your fingernail and lift it to the stop. When lifted, place the... - Page 19 Parachute Manual DRS-M210-V2 Remove the bottom rubber band (the one at the jagged edge) from the Parachute but keep the plastic cover shut or the parachute will unfurl. Insert the Parachute halfway into the Container with the jagged edge first.

Page 23: Device
Parachute Manual DRS-M210-V2 Device The DRS-M210-V2 is equipped with a micro SD memory card slot. The SD card is FAT32 formatted and used to store logfiles, perform firmware updates, and load configuration parameters. Device states and signals An indication light and a buzzer are used to inform the pilot about the DRS-M210- V2 internal system states as described in Error! Reference source not found.. - Page 24 Parachute Manual DRS-M210-V2 example take a look at the following few lines which modify the values for the maximum banking-angle as well as the maximum sink-rate to values different from their defaults: set MAX_BANK_ANGLE 45 set MAX_SINKRATE 800 Table 3 shows a list of available parameters.

Page 25: System Time
System Time The DRS-M210-V2 is capable of naming the log-files based on the current date and timestamp. Therefore the system’s time has to be set in advance. This is done once after fabrication but might be repeated if the system was not supplied with power for a very long time or you want to change it to your time zone. -
Page 26: Firmware Update
Store a file (.bin extension), provided by Drone Rescue Systems GmbH, in the root directory of the micro SD card to perform a firmware update. When the DRS powers up, the file will be found and the update process will start automatically. The status LED blinks violet during the update process which takes about 5 to 10 seconds (see 7.1 Device states and signalsError! Reference source not found.). -
Page 27: Storage
Always store the system in a dry environment to prevent moisture accumulating inside of the parachute canopy increasing the inflation time in case of a deployment. 10 Maintenance The DRS-M210-V2 parachute rescue system needs to be maintained once a year. The maintenance includes the following steps: • Repacking the parachute •...
