How to get image string through tool communication(RS485)


I’m trying to get image string from USB camera connected to Tool I/O(RS485)
I have an RS485 to USB adapter in the tool that I can connect the TCI RS485+/RS485- wire pair to.

To receive pictures from the tool to the usb camera, I need to send a commend to the camera via RS485.
I installed [rs485-1.0.urcap] and tried to connect robot ip with tool_tcp_port(54321) but it didn’t work. (Universal_Robots_ROS_Driver/rs485-1.0.urcap at master · UniversalRobots/Universal_Robots_ROS_Driver · GitHub)

The camera connected to the usb port of the CB3 was able to receive video streaming via ROS.

Do I miss something?

Hi Wrenn,

Welcome to the UR community!

You setup is not really clear to me. The adapter is a USB device from you description is also sound like your camera is a USB device? If that is the case your camera will only work if you connect it to a USB host.

If that is not the case, please share some details on your setup.

Best regards
