Replication of testing environments is a known challenge in the Functional Circuit Test world. Wiring an FCT fixture using wire wrap can take hours, and the validation of a tester itself, to ensure simple continuity and function, can take days. Anyone setting up a fixture-based test bench or rack-…

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,…

Create and Deploy Wireless Test FixturesOne of the benefits of using Acroname's BrainStem/MTM series modules in functional circuit test is being able to create and deploy "wireless" test fixtures - a fixture with no wire-wraps or cables. The small form-factor and low power of MTM modules can be…

Two example projects for USBHub2x4 With National Instruments We've recently been getting questions regarding the use of the Acroname USBHub2x4 from within National Instruments TestStand test management software. So we put together two example projects which wraps the BrainStem2 library…

Connecting multiple USB hubsIn this week's video we answered the popular question of: "Can I connect more than one USBHub2x4/BrainStem device to my computer?".  Not only did we prove that the answer is yes, but we also wanted to see exactly how many devices we could connect using our…

Not only do we make Manufacturing Test Modules (MTM), we also use them to test our own products. Using BrainStem® MTM modules to make a functional board level test system is incredibly simple. For the USBHub2x4, MTM allows us to make a test system that requires no external test equipment…

Using BrainStem Python for Turning USB Device On And Off Simple task automation for repetitive actions can be powerful aids in product development. Automatically connecting and disconnect devices from a USB bus is commonly done in manufacturing test and software regression test systems.…

Controlling data and power lines independently with HubTool applicationNotice that when the power line is enabled, the Android device indicates it as "charged". After enabling the data lines, the device then indicates that it enumerates as a media device from the USB Hub. Doing…

Acroname's BrainStem® technology is a foundational tool for bridging the gap between hardware and software systems. BrainStem controllers gather and relay peripheral information to other systems, which may be a host computer, additional microcontrollers or an array of sensors and testing equipment…

Today's mobile devices continue to integrate more features and functions into ever smaller packages. Features usually win over battery life during the design phase. In order to help quantify and develop test methods, Acroname was contracted by a major cellphone manufacturer to design a mobile…
