Here at Tru-Tronics our engineers link custom interfaces for wire harnesses, equipment cabinets, or PC boards directly to the tester with 64-conductor IDC flat cable. Connector boards do need not be used in this case. The Pin Map software We use with probe lets us easily configure your custom interface for any test point assignments you need and apply custom labels to each pin. We use the special software for Guided Assembly to ensure that the harness is assembled correctly the first time.
