Diagnostic Breakout Switch Board USB A/B Female
Best diagnostic tool for engineers troubleshooting USB connectivity and power issues.
This Diagnostic Breakout Switch Board from Winford Engineering is designed for seamless integration into existing USB cable connections. It provides a pass-through function while exposing all signals via accessible test points and headers. Individual DIP switches allow for the disconnection of data and shield lines, crucial for diagnostics, troubleshooting, and fault tolerance testing. The 5V power signal can be managed with an included jumper, and the ground connection remains permanently active for safety. Utilizing USB 2.0 A-Female and B-Female connectors, this compact board enables live system probing and manipulation without interrupting normal operation.

Know before you buy
Yes, the board is designed for live system probing. You can use the inline DIP switches to isolate specific data or shield lines while the device remains connected, allowing you to identify faults without breaking the entire signal path.
No, this board is specifically engineered for USB 2.0 standards. It will not support the higher data transfer rates or additional pins found in USB 3.0 or USB-C connections.
Yes, the board features a jumper that allows you to manually disconnect or reconnect the 5V power line. The ground connection, however, remains permanently active to ensure the system stays safely referenced.
The board provides clearly labeled test points and headers for all data and shield signals. You can easily attach oscilloscope probes or logic analyzer leads to these points while the device is in operation.
Yes, the board is available in a DIN rail-compatible version, making it suitable for integration into industrial environments. If you prefer a desktop setup, a version with rubber feet is also available.
No, the unit is bus-powered. It draws its operating power directly from the USB connection, so no additional power cables or adapters are required.
