How to connect your unit to the Robotiq User Interface ?

Sometimes, you need to test a unit on the Robotiq User Interface either for an application purpose or because you suspect there might be something wrong with your gripper.

Context


The Robotiq User Interface (RUI) is a useful tool to test or troubleshoot a gripper outside of its usual application. This method ensures that you’re testing the gripper in isolation, free of possible robot or software interference.

Information

1. Choose Your Coupling Type

Your connection setup depends on the type of coupling your gripper uses.

🟦 A. Standard Coupling

(GRP-CPL-0XX or AGC-CPL-0XX-002)

What you need:

  • Standard coupling with a 1 m pigtail cable

  • 10 m extension cable: CBL-COM-2065-10-HF

  • RS485 to USB converter: ACC-ADT-USB-RS485

  • Power source: 24V 1A (via robot or external supply)

Steps:

  1. Connect the gripper to the 10 m cable, then to the RS485 to USB converter.

  2. Plug the converter into your computer.

  3. Power the gripper via robot or an external 24V 1A source.

  4. In the RUI, select the gripper model you're testing.

🟨 B. I/O Coupling

What you need:

  • I/O coupling with Micro-USB to USB converter (built-in)

  • Power source: 24V 1A (via robot or external supply)

Steps:

  1. Plug the Micro-USB into your computer.

  2. Power the I/O coupling using the robot or external supply.

  3. In the RUI, select “I/O Coupling” instead of a specific gripper model.

3. Use Auto Connect in the RUI

Once your device is powered and connected:

  • Click Auto Connect in the RUI.

  • The software will scan for any connected unit and establish communication automatically.

4. Troubleshoot with “Recover Device”

If auto-connect fails:

  1. Manually select the correct COM port.

  2. Click Recover Device.

  3. Remove the gripper from the coupling and reattach it within 10 seconds.

  4. The RUI will scan for all supported slave IDs and baud rates.

Conclusion


Connecting your gripper to the Robotiq User Interface allows you to isolate and test the hardware independently. Choose the right connection method based on your coupling type, and use “Recover Device” if needed to establish communication.
