Abstract:
A test fixture includes a first RS-232 connector and a second RS-232 connector. The data terminal ready (DTR) pin of the first RS-232 connector is connected to the DTR pin of the second RS-232 connector, and the clear to send (CTS) pin of the first RS-232 connector is connected to the CTS pin of the second RS-232 connector. The DTR pins are further connected to a power pin of each of the test computers. The test fixture sets a high level voltage for the connected DTR pins, and sets a low level voltage for the connected CTS pins according to the commands of turning on the test computers sent by the control computer, to turn on the test computers. An auto shutdown software included in each of the test computers is executed to shut down the test computers.
