•Timelapse –user defined interval for shutter release

•PWM INPUT

•Digital Capture –*shutter release only for Sony camcorders

#REC CHANNEL VALUE TABLE

Setting up and using #REC is very simple. It can be controlled via transmitter or flight controller. Below you will find a table that

illustrates #REC functions, which channels they are allocated to and the values for engaging the functions.

a still camera because of legal reasons from Sony Corp.

FLIGHT CONTROLLER / TRANSMITTER INTEGRATION

TRANSMITTER

#REC can be controller via transmitters PWM output interface.

If utilizing PWM based receivers simply plug in the channels that you wish to control on #REC into the receiver and adjust the output

values required for activating the functions.

Conversion tables for most common transmitter brands can be found on the following link: https://www.seagulluav.com/transmitter-

pwm-conversion-table/

PIXHAWK / PIXRACER / ARDUPILOT BASED FC

#REC can be connected to a Flight Controller to control functions automatically or setting the Flight Controller to act as a passthrough

for the signal activated by transmitter.

Please note that none of the Ardupilot based flight controllers output power through the rails - therefore #REC needs a power supply.

To achieve this, it is recommended to utilize an external BEC of 5V to ensure proper functionality for #REC or any other accessories.

Below is an illustration of usable channels for connecting #REC for AUTOMATED TRIGGERING:

MISSION PLANNER

If you wish to trigger Seagull #REC from a Flight Controller, setting it up in Mission Planner is also straight forward.

Start Mission Planner and follow the steps below:

1. Click on INITIAL SETUP >> OPTIONAL HARDWARE >> CAMERA GIMBAL

2. "SHUTTER" - in the drop-down list, chose the channel that Seagull #REC CH1 SHUTTER RELEASE channel is connected to.

3. "PUSHED" - Set the "Value" as in the table:

State / Function

Value

Range

NEUTRAL

1500 μS

1400 <> 1600 μS

AF-T

1330 μS

1266 <> 1399 μS

IS-T

1200 μS

1132 <> 1265 μS

4. "NOT PUSHED" –Set the value "1500" ( Neutral state –see table above )

5. "DURATION" –Set the value "1" for AF-T mode or "10" for IS-T mode

(values may vary depending on how long it takes for your specific camera model and lens configuration to lock focus. Try increasing or

decreasing the values to find the sweet spot where the camera can keep up with the duration time that the shutter is held pushed/triggered

for)

DJI Flight Controllers / A3

#REC can be controller via DJI A3 flight controller. It is very easy to setup automated flight photo capturing via DJI Assistant 2

software. For controlling more features of #REC an expansion kit is required, since by default it is not possible to utilize other F ports

and bind them to the channels of LB transmitters.

Below is an example of integrating #REC and configuring via DJI Assistant 2:

AUTOMATED CAMERA ON / OFF

If you wish to integrate "Camera On/Off" into your Survey / Mission plan with Ground control or Mission Planner software, simply

follow the steps below. (Please note that you might need to setup the Flight Controllers channels in the parameters to function as

SERVO/PWM OUTPUT. As well as some of the Sony cameras require the power switch to be set onto ON position –then powered OFF

via #REC command for below scenario to work)

In this scenario we want to turn on the camera after take-off.

NOTE: Repeat the sequence at the end of the mission in order to retract the lenses to protect the mechanism before landing. Very helpful on plane platforms as well as multirotor
