  • Insert SD card, label side facing up, until it clicks into place.
  • To remove SD card, press the edge of the card until the spring mechanism unlatches.
NOTE
An SDHC Class 10 SD card with a write-speed capability of at least 45 MB/s is required (32 GB SanDisk Extreme recommended). SDXC SD cards are not compatible with the RedEdge-M camera.

External Connections

Refer to RedEdge-M Integration Guide for details on connectors, pin-outs, and voltage specifications. When removing the cables that plug into these connectors, use a small flathead screwdriver to pry off the connector at the plastic interface. Do not pull on the wires to unplug these connectors.

Connect DLS and GPS Module

The Downwelling Light Sensor (DLS) is a 5-band light sensor that connects directly to a MicaSense RedEdge-M camera. The DLS measures the ambient light during a flight for each of the five bands of the camera and records this information in the metadata of the images captured by the camera. When properly installed and calibrated, the information sensed by the DLS can be used to correct for lighting changes in the middle of a flight, such as those that can happen due to clouds that cover the sun during a flight.

  • Connect DLS to the camera port labeled “DLS/GPS”using the 6-pin cable. The other end of the 6-pin cable is connected to the “CAM” port in the DLS.
  • Connect the GPS module to the DLS using the two cables that are attached to the GPS module (4-pin and 6-pin).
  • If stand-alone GPS module is used (without DLS):
    • Connect 6-pin cable that is attached to GPS module to camera connector labeled “DLS/GPS”. The 4-pin cable attached to the GPS module is left unconnected.
  • For more advanced integrations where GPS data is provided by the autopilot or other GPS source, refer to RedEdge-M Integration Guide.
  • To remove connectors, do not pull on wires; instead use a small flathead screwdriver to pry out the connector. See “External Connections”.

DLS and GPS connected

 

CAUTION
Always connect the DLS or the GPS module to the camera before turning on the camera. Failure to do so may damage the DLS or the GPS module.

 

Connect Power Cable

rem-pwr-trig-sm.png

  • Refer to RedEdge-M Integration Guide for details on power requirements and connector pinout.
  • Connect either the USB power cable, or another power cable to connector labeled “PWR/TRIG”.
  • To remove connector, do not pull on wires; instead use a small flathead screwdriver to pry out the connector. See “External Connections”.

 

CAUTION
Power must not exceed 15.8V DC. Ensure correct pinout and polarity before connecting power. Failure to follow these instructions may result in permanent damage to the camera, the DLS, or the GPS module.

 

Using the RedEdge-M Camera

Power ON the Camera

rem_power_button_sm.png

  • The camera starts automatically when power is connected.
  • Alternatively, press and release the Power Button.
  • The Status LED will remain OFF while the camera is initializing (approx. 15 seconds).
  • After initialization has completed, Status LED will flash at approximately once every 1.5 seconds.

 

NOTE
The camera will automatically turn ON when power is first applied to the external power connector. If the camera is manually turned OFF, it can be re-powered ON by pressing the Power Button.

 

To Power OFF the Camera

  • Press and hold the Power Button for at least 5 seconds.
  • The Status LED will stop flashing once the camera has shut down.

Camera LED Signals

One flash indicates normal behavior, that the camera is operating as expected. More than one flash indicates an issue as outlined in the following table:

Color

Type

Meaning

Green

1 Flash

Camera is ready for operation (it has a GPS fix and more than 2 GB available on SD card)

Blue

1 Flash

Capture completed

Yellow

2 Flashes

GPS unit detected, but does not have a fix

Red

3 Flashes

GPS timeout

Red

4 Flashes

No SD card installed

Red

5 Flashes

SD card is full (or almost full)

 

DLS LED Signals

There are two green LED lights on the DLS, one on either side of the unit. The meaning of the LEDs is as shown in the table below. The LEDs are small and may not be easy to see without getting close to the unit. Refer to the following table for signal meanings:

DLS LED Signal Type

Meaning

4 simultaneous flashes on both LEDs

This occurs upon boot-up of the DLS

Sporadic flashing

Communications received. This is normal behavior

Alternating blinking between the two LEDs

Indicates a software/hardware problem. If the problem persists, contact MicaSense at support@micasense.com

Both LEDs solid ON

 

CAUTION
Power OFF the camera before removing the SD card. Failure to do so may corrupt some of the files in the SD card if they are still being written.

 

Capturing Images (Manual Trigger)

With the camera turned ON and SD card installed, press and release the Manual Trigger button.

rem_power_button_sm.png

NOTE
Captures created using the manual trigger are taken using a mode designed for panel pictures. Images taken this way may appear significantly darker than images taken using other trigger methods.
