Interface Connectors:
All units employ industry-standard 64-pin dual-row latch headers, 0.1" pin spacing. Order identical male headers (Item 851), mating sockets (Item 855), and 64-conductor flat cable (Item 854) for custom interface projects.

CableEye's Test Logic: All mathematically possible combinations of test points are measured to exhaustively check wiring connections. Complex networks of wiring, and wiring harnesses with many connector heads, may be measured, stored, and compared to matching wiring even when the graphic image becomes too involved for clear presentation.

Printer Requirements: Any printer with a Windows driver will suffice.
