GPIO Connector

The GPIO connector provides two general-purpose inputs (GPI) and two general-purpose outputs (GPO). The figure below shows the pinout of this connector and the color coding of the Mōvi Pro Wave Remote Control Cable (Freefly P/N 910-00661).

Mōvi Pro Wave Remote Control Cable

The settings to use for remote start/stop with the Mōvi Pro and Mōvi Controller are shown below:

Custom Remote Start/Stop

A custom remote start/stop cable can be created by following the wiring diagram below. The GPIO are optically isolated, so the host must supply a voltage (3.3V or 5V is okay) to power its side of the optocoupler. The current drawn will be <20mA.

The user input connects to Pin 6: GPI2/RS. It can be a simple switch, as in (a). In this case, the switch connects the GPI2/RS pin to GND (0V). By default, each single press will toggle the recording state on or off, just like the dedicated Record Button. For wireless remote start/stop, a relay- or transistor-based RC switch can also be used.

Alternatively, a logic signal from a host device can be used to drive Pin 6: GPI2/RS, as in (b). The host device should be connected to the same ground (0V) as Pin 1: GND, and the logic high voltage should match the voltage supplied to Pin 2: VIN. GPI2/RS is internally pulled-up to VIN, so open-drain logic can also be used.

The behavior of the input is determined by the GPI Setting:

Edge-Triggered, GPI:EDGE (Default)

The recording state is toggled on or off at each rising edge of the GPI2/RS input, as illustrated in the figure below. In the case of a simple button, recording would start or stop each time the button is released, since the button connects GPI2/RS to GND (0V). There are some restrictions on the pulse width and frequency implemented to prevent glitches, also shown in the figure below.

Level-Triggered, GPI:LVL

The camera records when the GPI2/RS signal is low and returns to standby when the GPI2/RS signal is high, as illustrated in the figure below. In the case of a simple button, the camera would record while the button is held down, since the button connects GPI2/RS to GND (0V). There are some restrictions on the pulse width and frequency implemented to prevent glitches. These are detailed in the figure below.

The Mōvi Pro Wave Remote Control Cable (Freefly P/N 910-00661) is available on the . You can use this now for remote start/stop on your Mōvi Pro. It will also enable full camera control via UART in a future firmware update. You can also use this as a donor cable to wire up a custom remote start/stop for other systems (see below).
