Abstract
A service redirect operation mode allows a tester device to perform software burn-in, firmware upgrade, and other related device interrogation via a USB Type-C connection. The service redirect operation mode is implemented by modifying a termination state of the configuration channel pins of the USB Type-C receptacle of the device under test. Software and/or hardware executing on the device under test re-configure the resistive arrangement of the configuration channel pins, causing one pin to be connected to a reference voltage via a pull-up resistor and the other pin to be connected to ground via a pull-down resistor. When operating in the service redirect operating mode, two additional signal lines of the USB Type-C receptacles may be used to exchange information between the tester and the device under test using a user-specified interface protocol.
