A tiny Bluetooth receiver that hangs on your camera and fires it from your remote or phone.

Thank you for purchasing the ORTTA Io, a small Bluetooth receiver for the shutter-release socket of your camera. Io lets Ortta remotes and the Ortta app fire cameras that have no Bluetooth of their own, and it can run the shooting programs by itself.
Most remote receivers are large. You take one out of the bag, connect it to the camera with a shutter-release cable and mount it on the hot shoe. Io is different. Hang it on the camera strap or on the camera with a small lanyard, with its 2.5 mm socket fitted with the adapter plug for your camera. When you need it, turn the plug and push it into the camera. That is all: no cable, no hot shoe, nothing to take out of the bag.

You can control Io from:

The adapter plug is not in the box. There are about ten different plugs, one or more for each camera model, so buy the one that fits your camera separately. See Camera compatibility.


Io has one button.
| Action | When Io is off | When Io is on |
|---|---|---|
| Click | Turns Io on | Takes a photo |
| Long press (about 2 s) | Turns Io off. The green LED flashes once, long, and then you can let go. |
Connect Io to a USB power source with the supplied USB-A to USB-C cable. The orange LED lights while it charges and turns off when the battery is full. A full charge takes about 30 minutes, and the battery lasts about 8 days while it is connected.
Choose the adapter plug that matches your camera's remote release socket. Camera brands use different plugs. See Camera compatibility.
Push the plug into the 2.5 mm socket of Io, and hang Io from the strap eyelet of your camera with the lanyard. Io now hangs next to the camera with the plug on it, ready to use. The plug turns in the socket, so you can set it at the angle that fits your camera.

When you want to use Io, hold it and turn the plug until it points at the remote release socket of the camera.


Push the plug into the remote release socket of the camera.

Io is connected. It stays on the lanyard next to the camera.

When you do not need Io, pull the plug out of the camera and turn it back, and let Io hang next to the camera.
Io fires the camera over the shutter-release cable, so the camera does not need Bluetooth. Set the camera to a mode in which the remote release works (for most cameras, the drive mode or the self-timer / remote setting; see your camera's manual).

Io pairs with an Ortta remote or with the Ortta app. Io is always ready to pair while it is on, so you do not have to press anything on Io first. Do not pair it in the Bluetooth settings of your phone. The pairing is rejected.
With Jupiter, Jupiter Pro, Pluto 2 or Pluto 2 Pro
Turn on Io.
On the remote, open Settings › Devices › Add. The remote scans for devices.
Select Io from the Discovered list and press OK.

The remote shows Paired. Io now appears in the Devices list.
With the Ortta app
Turn on Io and open the Ortta app.
Open the Device page, either way:

The app scans automatically. Io appears under Discovered devices.

Tap Io. In the dialog, tap Pair Device.

Io now appears under Paired devices.

Io can be connected to two devices at the same time, for example Jupiter Pro and the Ortta app. A third device can connect only after one of them disconnects.
Jupiter, Jupiter Pro, Pluto 2 and Pluto 2 Pro all use Io as a receiver. You pair Io with the remote once (see Pairing). After that the remote finds Io again by itself whenever both are on.




See the manual of your remote for the details: Jupiter, Jupiter Pro, Pluto 2 and Pluto 2 Pro.
Io runs these programs. You set the parameters on the remote, in the Ortta app or on the Apple Watch, and start the program there.
| Program | What it does |
|---|---|
| Shutter | Takes a photo. Has a self-timer and a bulb mode for long exposures. |
| Timelapse | Takes photos at a regular interval. |
| HDR | Takes a series of photos with different shutter times, using the Bulb mode of the camera. |
| Startrail | Takes a long series of photos for star trails. |
| Video | Starts and stops video recording. |
| Timer | Starts a program at a set time. |
| ND Filter | Long exposure, using the ND filter value you choose. |
| Starscape | Calculates the longest exposure for sharp stars (the 500 rule). |
The programs work the same way as on Pluto 2. See the Pluto 2 manual, chapter Shooting Programs, for the parameters of each one.
Because Io only has a shutter-release cable to the camera, it fires the camera but does not change camera settings. Set the exposure, ISO and aperture on the camera first.
For HDR, set the camera to BULB mode. Io only controls how long the shutter stays open, and it changes this time from photo to photo. For Startrail and ND Filter, put the camera in manual mode and set the shutter speed on the camera, or use BULB mode if the program needs it.
Io connects to the Ortta app over Bluetooth, after you pair it. The app can:

Smart Sensors use the sensors of your phone to fire the camera through Io. The phone must be near Io while the program runs.
| Mode | How it triggers |
|---|---|
| Sound | Uses the phone's microphone. |
| Vibrate | Uses the phone's accelerometer; fires when vibration exceeds the set threshold. |
| Motion | Uses the phone's camera to detect motion. Zoom in and out to define the watched area, and adjust the sensitivity to the size of the subject. |
| Distance | Fires every set distance travelled. Good for road-trip time-lapses. |
| Voice | Recognizes a spoken command. Say "jarvis", "photo", "cheese" or "shoot" to take a picture, or "video" to start or stop recording. English only. |
| Smile | Detects a smile (or, in Blink mode, a blink) and fires 1.5 s after a notification sound. Good for selfies. |
The pages are the same as on Pluto 2. See the Pluto 2 manual, chapter Ortta App, section Smart Sensors, for the screenshots and the settings of each mode.
The Ortta Camera app turns a phone into a camera. Io connects to it over Bluetooth and works as a manual Bluetooth remote: click the button on Io to take a photo with the phone. It cannot record video. This does not fire your camera, and it does not need the shutter-release cable.
Pair Io with the Ortta Camera app the same way as with the Ortta app (see Pairing): open the Device page, tap Io under Discovered devices and tap Pair Device.

The Ortta Watch app controls Io from your Apple Watch. The watch connects to Io directly over Bluetooth, so you do not need your phone in the field.

With Io connected, you can start and watch the Intervalometer programs from the wrist: Shutter, Timelapse, Startrail, HDR and ND Filter. Set the parameters on the watch and start the program there. The sensor programs of Pluto 2 (such as Sound and Lightning) do not work with Io. The watch pages look the same as with Pluto 2; see the Pluto 2 manual, chapter Watch App.
The watch shows no photos with Io, because Io only releases the shutter. Photo review needs an Io Pro.
The standard Io only releases the shutter. It cannot write the position into your photos.
Nikon. Nikon cameras get the position through the Ortta Io for Nikon, a dedicated Io with a 10-pin or GPS terminal connector. The 10-pin version is for high-end Nikon cameras that use the DC0 cable; the GPS terminal version is for cameras that use the DC2 cable. Pair it the same way as an Io (see Pairing) and plug it into the camera. Jupiter Pro, Pluto 2 Pro and the Ortta app can send GPS data to it. On the remote, set Geotag rate to anything other than Off.
The Io Pro cannot geotag Nikon cameras. It geotags Canon cameras over USB.
New firmware adds features and fixes bugs. You update Io over Bluetooth with the nRF Connect app; no computer or cable is needed.
What is the difference between Io and Io Pro? Io fires the camera over a shutter-release cable. Io Pro connects to the camera over USB: it can show live view, send photos to Jupiter/Jupiter Pro, Pluto 2/Pluto 2 Pro and Ortta app and write the phone position into Canon photos. The programs are the same.
Does my camera need Bluetooth? No. Io uses the shutter-release socket, so it works with any camera that has one.
Do I need Io if my camera has Bluetooth? No. Jupiter and Pluto 2 can control cameras with Bluetooth remote support directly. Io is for cameras without Bluetooth, and for running programs on the camera side.
Can I leave Io on the camera? Yes. Io hangs on a lanyard and plugs into the camera only when you need it. When no remote or app is connected, Io turns itself off after 30 minutes, so it does not drain the battery while it hangs on the camera.
| Problem | What to do |
|---|---|
| Io is not found when pairing | Check that Io is on. Stay close to Io while pairing. Io can connect to two devices at a time, so disconnect one if two are already connected. Do not pair in the Bluetooth settings of your phone. |
| The camera does not fire | Check that the adapter plug is fully in the camera socket and that it matches your camera. Check that the camera is on and set to a drive mode that works with a remote release. |
| The remote loses Io | Io has a shorter range than your remote. Move closer, and keep Io away from metal and the body. |
| I turned off the remote or the app and the camera is still shooting | This is normal. A program runs on Io, so it keeps going after the remote or app disconnects, and Io does not turn itself off while it runs. When you reconnect, the remote shows the running program again and you can stop it there. You can also long-press the button on Io to turn it off. |
