The ScanPCI-280 is a test module that enables boundary-scan (JTAG) testing of PCI cards. This product adds boundary-scan test coverage to the circuit traces that are directly connected to the card edge connector pins. The module takes advantage of the JTAG interface built into the PCI bus to access the boundary-scan components of the PCI-based unit under test (UUT). The system fully supports 3.3- and 5-V compatible PCI cards. During the test, the PCI card UUT edge connector plugs into the ScanPCI-280 module mating connector. This enables access to the boundary-scan controllable digital I/O pins provided by the company's ScanIO-280LV companion product.
