USB-2 MASTER
This port permits the camera to operate as the Slave camera in a Master / Slave camera pair. To establish
control, plug the square end of a USB-2 cable into the lower USB port of the RED ONE camera to act as a
Slave, and the rectangular end of a USB-2 cable into the upper USB port of the RED ONE camera to act
as the Master. Then power cycle both cameras. On boot up the two cameras will automatically establish
Master / Slave mode.
Once connected using the USB cable, User Interface commands and remote triggers received by the
Master camera are transmitted to the Slave camera.
