What's a USB device tree, and why is it important for conference room A/V? Understanding the USB Device Tree Acroname's ControlRoom web-based software works with our intelligent USB hubs to visualize the USB device tree of the host. USB has the concept of tiers: the host and root hub are on…

Master your USB in Conference Rooms with ControlRoom.Acroname's ControlRoom allows you to remotely enable, disable, monitor, and reset USB ports in the connected conference rooms. This means you can solve many issues that would otherwise require a "physical" reset - without ever…

Discover the Power of USB-C USB Power Delivery (USB PD) is a crucial aspect of USB-C technology, allowing for faster charging and increased power delivery capabilities of up to 240 Watts! If you haven't checked out our blog on The USB-C Connection Statemachine, we recommend reading that first.…

USB-C Specifications: Getting Started The Universal Serial Bus (USB) has become an essential component of modern computing, providing a standard interface for a wide range of devices. The latest iteration of USB technology, USB-C, offers several improvements over the previous generation of USB-A…

What is this "Alt Mode" you speak of?  USB Alternate Modes are a powerful feature of USB-C technology that allows for the transmission of video, audio, and other data formats outside standard USB across a USB-C connector. These alternate modes, such as Thunderbolt 4 and DisplayPort, are…

 Daisy Chain Acroname USB HubsCustomers often ask how many Acroname USBHub3+ hubs can be daisy-chained.The answer is pretty simple: four.However, getting there requires some understanding of the USB specification and the internal topology of Acroname hubs. Also, by following our suggested…

Adding more than two USBHub3+ hubsSome customers who have been using multiple Acroname USBHub3+ hubs have shared with us that they cannot add more than two USBHub3+ hubs to their system or that they need more USB resources. As it happens, this is not a limitation of USBHub3+ itself,…

OVERVIEWA common automation system requirement is to drive or actuate high power loads using low level voltage signals. Motors, solenoids, relays and capacitive loads can be actuated with appropriate circuitry that is only possible using small current/voltage combinations often found in…

INTRODUCTIONThe Sharp family of infrared range finders are used extensively for robotics and automatic distance measurement applications. Unfortunately, the output of these sensors are inherently non-linear. In other words, a big change in output voltage does not always indicate a big change in…

INTRODUCTIONElectromotive force (EMF) refers to the voltage generated by a spinning motor. Measuring this voltage in order to determine the rotational speed of a motor is commonly called Back-EMF since the voltage tends to "push-back" against the circuit driving current into a motor's windings.…
