Perform a Stress Test

Perform a stress test before important projects to ensure the reliability and stability of your gear. A stress test subjects your DSMC®  system and equipment to the increased stress of prolonged operation. If any components are developing issues, this test will help identify those problems before you have an equipment failure during a major shoot.

  1. Configure your camera.
  2. Perform a black shade calibration (sensor calibration).
  3. Enable the Sensor Test Pattern in the Maintenance menu.
  4. Select the resolution that you want.
  5. Select the highest available frame rate.
  6. Perform a secure format of the SSD.
  7. Record a full SSD of footage.
  8. Perform a secure format of the SSD.
  9. Repeat step 6 to step 8 to test multiple SSDs.

NOTE: If an error occurs, save a log file and submit a Technical Support request.

NOTE: Problems or dropped frames found during the stress test display as “Errors” in the bottom of the user interface.


Save a Log File

A log file is a detailed text file of the processes and operations performed by the camera. If you contact RED for support, you may be asked to send a log file.

To save a log file, follow the instructions below:

  1. Ensure that a RED MINI-MAG SSD is properly mounted to the camera.
  2. Go to Menu > Settings > Maintenance.
  3. Select Save Log

    The log file is saved as a *.txt file in the SSD root directory.

NOTE: The camera automatically saves a log file when it is turned off properly and an SSD is mounted.


Firmware Does Not Upgrade


  • During an attempt to upgrade firmware, the PWR and REC LEDs flash red.
  • After an attempt to upgrade firmware, the firmware version does not change.

Potential Resolutions

  • After downloading the firmware upgrade file, ensure that you unzip the file before saving it to the SSD.
  • Ensure that the “force_upgrade” folder is saved to the top level of the SSD, and not to a subfolder.


Camera Does Not Turn On


The camera does not turn on (does not boot up), even when powered.

Potential Resolutions

  • Remove all accessories and power the camera using the DSMC AC Power Adaptor.
  • Perform a Hard Restore.
  • Update the camera firmware to the latest release build.


Tighten DC IN Connector


The DC IN connector nut is loose.

Potential Resolutions

Tighten the loose DC IN connector nut using a pair of heavy-duty strong point tweezers.


OPTIONAL: Add a small amount of Loctite 222 (low strength thread locker) to the threads of the DC IN connector nut to prevent the connector from becoming loose again.


Stereo Microphone and Camera Compatibility

The two balanced mono 3.5mm microphone ports on the front of DSMC camera BRAINs are intended for use with a mono mic level signal. If you are using a stereo microphone with a built-in cable, such as the Rode Videomic Pro, you will need to attach a stereo-to-mono adapter in order to receive an audio signal successfully.

The unbalanced stereo 3.5mm microphone port on the DSMC2™ Base Expander and the DSMC2™ V-Lock I/O Expander are intended for use with either a mono or stereo mic level signal.

The XLR Microphone Cable on is for balanced inputs (i.e., +/- inputs). It may not work directly plugged into a standard microphone without another cable in between.

To solve this, you could use a 3.5mm stereo breakout cable to connect two (2) microphones (L or R):

You could also use a 3.5mm stereo to XLR breakout cable:

NOTE: when selecting a cable you will need a "breakout" cable and not a "splitter" or "Y" cable. The"splitter" or "Y" cable will simply duplicate the common connector leaving you with the same potential issue.

If you want to record only one (1) single channel on a DSMC2 camera, you will need to use a stereo breakout cable, a stereo microphone, or mono microphone.


Media is Not Supported


The message “This media is not supported with your current version of DSMC firmware” displays if the camera is not running at the minimum required firmware for the SSD.

Potential Resolutions

Update the camera to the latest firmware. For more information about the firmware requirements, go to the RED MINI-MAG - Media Not Supported Message article.


DSMC Fan 2.0 (Bottom) and the DSMC Mg PL Mount 2.0 Compatibility

For EPIC and SCARLET cameras, the DSMC Fan 2.0 (Bottom) and the DSMC Mg PL Mount 2.0 are not natively compatible with each other, since the fan grill prevents the lens mount locking ring from rotating. To use these devices together, remove the lower tabs from the locking ring using a T8 TORX® driver.


Wireless Monitoring with RED Cameras

Using a third-party wireless monitoring system that is powered from a source external from the camera itself might damage your camera.

Some of the transmitters for wireless monitoring systems require ~7-17V unregulated input voltage.  When this power comes from an external source - such as a third-party battery or battery plate - the HDMI and 3G-SDI output connectors on the camera BRAIN or DSMC2 Base Expander can be damaged.

RED recommends that you avoid using wireless monitoring systems powered by external sources with your EPIC/SCARLET BRAIN or DSMC2™ Base Expander.

The following DSMC2 Expanders offer a USB Power output connector and are intended for use with accessories requiring additional power, such as wireless transmitters:

For more information, download the corresponding Operation Guide for your camera.

If you experience issues monitoring out of your RED camera, save a log file and submit a Technical Support request.
