General Description
Insert this diagnostic Breakout Test Board into existing cable connections to get access to signals or to re-map connections via test points and spring terminals; this is the pass-through function of this board. This board comes with no connection between the two connectors, each connector pin is brought out to spring terminals allowing for signal cross-wiring or pin re-mapping. This aids in diagnostics, troubleshooting, fault tolerance testing, or re-routing specific signals within a cable. This compact design is meant to be inserted into the cabling of a system during operation.
This board contains dual DB9 connectors (1 Male, 1 Female). This connector selection generally allows for very convenient insertion into existing cable configurations, without the use of gender changers, etc.

Technically, the correct term for a DB9 connector is DE9, but that term is not commonly used.

A breakout test board may also be referred to as a "measurement breakout", "pass-through board", "test breakout", "inline test adapter", or "breakout testing board".
