7.6.1 Powering 12 V Accessories
One 12 V output with a 2-pin LEMO connector is located on the right
side of the camera. It is limited to 12 V and can supply a device with a
current of up to 2.2 A, depending on the camera power supply.
7.6.2 Powering 24 V Accessories
Two 24 V remote start/stop (RS) outputs with 3-pin Fischer connectors
are located on the right side of the camera. They can supply two
devices with a combined load of up to 2.2 A (shared with the EXT
connector power out), depending on the camera power supply. When
the camera is powered from a source with a voltage below 24 V, they
output 24 V. If the camera's power source supplies more than 24 V, this
voltage level is also present on the RS outputs.
Besides powering accessories, the RS outputs can also be used to send
a remote start/stop signal to the camera.
