USB-C ports have to handle a variety of functions including data transfer, power delivery, and DisplayPort (DP) Alt Mode video output. Device manufacturers need to perform factory End-of-Line (EOL) testing to make sure that their products meet specifications In this blog post, we'll be looking at how to automate and speed up EOL testing of DisplayPort (DP) Alt Mode with Acroname's USB-C-Switch.
In modern manufacturing environments, devices often rely on local USB storage for configuration and firmware updates, data logging, and backup. It is often necessary to update or process this data by connecting the drives to another host, usually by manually unplugging the drives.
USB-C functional tests involve a lot of cable plugging and unplugging, connector flipping, and device swapping. Acroname's USB-C-Switch handles those connections for you, providing control through our HubTool GUI application or BrainStem API, even remotely!
Suppose you’re a test engineer working on USB compliance testing. You have a well-equipped lab with some high-end test equipment. But you’d rather be in your office doing other work than in the lab plugging, unplugging, and flipping cables while stepping through test scripts.
Acroname USB-C switch lets you virtually swap equipment, cables, connect, disconnect, and even perform cable flip tests. Even remotely!
Often a simple USB switch with a physical button is used to switch USB devices between two different host computers. In many cases it would be nice to execute the host switch without physically pushing a button on the device. The Acroname Programmable USBHub2x4 hub allows a user to switch hosts programmatically without pushing a button.
Acroname’s BrainStem-enabled programmable USB-C-Switch can be very useful to help automate and monitor USB connections in test environments. USB-C-Switch handles USB connections differently than a USB hub and also introduces the MUX entity to the BrainStem function libraries.
In this blog post, we will illustrate the connectivity and control aspects and show a control example in Python.
