The DSMC2™ V-Lock I/O Expander offers a variety of Input/Output connections, as well as an industry standard V-Lock mount to power your DSMC2 camera using RED BRICK® or other v-mount batteries.

Constructed from lightweight and durable magnesium, this expander module mounts directly to the rear of the camera BRAIN® and offers connections for the following:

  • DC Power input (DC IN)
  • HDMI 1.2 output (Type A socket)
  • 3G-SDI output (HD-SDI, 75 Ω BNC)
  • CTRL & SYNC ports (2x 00B LEMO 4-Pin, Timecode and Genlock support)

The DSMC2 V-Lock I/O Expander also features a selector switch that enables the BRAIN to automatically boot when power is provided via the DC IN connector on the expander. This feature allows you to use a connected DC input supply to turn the BRAIN on and off when the camera is mounted in remote or difficult to maneuver locations. This expander is an ideal solution for a wide variety of production environments—from low-profile run-and-gun situations to studio shoots that require mobility.
