How to change the presets of the I/O Coupling?

Configure up to four gripper actions using the Robotiq User Interface for optimal automation control.

Context

The Robotiq I/O Coupling lets you control a gripper without external cabling by using digital input signals. However, control is limited to four preset actions that must be configured in advance. This article explains how to use the Robotiq User Interface (RUI) to define these presets and upload them to your I/O Coupling device.

You can use this method with both Adaptive Grippers (2F‑85, 2F‑140, Hand‑E) and Vacuum Grippers.

1. Prepare the Software

  • Download the Robotiq User Interface (RUI) from the Robotiq Support site.

  • Install it on a Windows computer.

 

2. Connect Your I/O Coupling

  • Use a micro-USB to USB cable to connect the I/O Coupling to your PC.

  • Launch the RUI software.

 

3. Auto-Connect the Device

  • In the Robotiq User Interface:

    • Select "I/O Coupling" from the device list.

    • Click “Auto Connect”.

  • The device will be detected, and its configuration window will open.

 

4. Select Gripper Type

  • Choose the correct gripper category:

    • Adaptive Grippers – for 2F or Hand‑E grippers

    • Vacuum Grippers – for EPick or AirPick

  • This will display relevant parameters based on your device.

5. Configure Up to Four Presets

You can define four action presets triggered by robot I/O signals. Each preset can include:

  • For Adaptive Grippers:

    • Position (open/close %)

    • Speed

    • Force

  • For Vacuum Grippers:

    • Vacuum level

    • Blow-off setting

    • Gripping mode

 

Example for Adaptive Gripper:

  • Preset 1: 0% closed, 100% speed, 50% force

  • Preset 2: 80% closed, 50% speed, 100% force

 

6. Enable I/O Control Mode

  • Check the option: “Device Controlled by I/O Digital Inputs”

    This setting tells the I/O Coupling to trigger actions using robot digital outputs.

 

7. Save Configuration to the I/O Coupling

  • Click “Save presets configuration to I/O Coupling”

  • Wait for confirmation that the write is complete.

  • You can now disconnect the USB cable and mount the I/O Coupling back onto your robot.

 

8. Trigger Presets via Robot I/O

Each preset is activated by a binary combination of two digital inputs:

  • 00 = Preset 1

  • 01 = Preset 2

  • 10 = Preset 3

  • 11 = Preset 4

You can control these outputs directly from your robot program.

For UR and TM Robot, you can use the plugin available to control the I/O Coupling. 

 

Conclusion

By using the Robotiq User Interface, you can preconfigure four I/O Coupling presets for your Adaptive or Vacuum gripper. This enables simple, cable-free robot control using only digital signals—ideal for compact setups with basic automation needs.
