As business needs grow, the demand for more efficient, simple and cost effective testing methods increases. A testing system, for hardware, that allows many devices to be tested concurrently and uses automated techniques, is one of these methods. The Ethernet provides one of the best forums for remote access to end devices. By connecting devices to an Ethernet network, they can all be tested using the one system. The result is that the intelligence is centralised and the work distributed throughout the system.
The Ethernet Connected Hardware Tester is a system that allows hardware to be tested from a remote location, using a PC. The device to be tested is connected to a PC through the parallel port, which is running the ‘server’ program. At a remote location another PC running the ‘client’ program tests the hardware based on the user’s requests. The Ethernet Connected Hardware Tester is a prototype of a system that would eventually contain an embedded server.
