Abstract

A two port bi-directional diagnostic wrap cable assembly is disclosed. The assembly has connectors on each end that mate with communications I/O adapter connectors. One end of the assembly has a Printed Circuit (PC) board with uniquely wired bi-directional circuits, allowing either end of the assembly to be plugged into either communications I/O adapter port.

Bi-Directional Wrap Assembly for 2 Port I/O Adapters

      A two port bi-directional diagnostic wrap cable assembly is
disclosed.  The assembly has connectors on each end that mate with
communications I/O adapter connectors.  One end of the assembly has a
Printed Circuit (PC) board with uniquely wired bi-directional
circuits, allowing either end of the assembly to be plugged into
either communications I/O adapter port.

      The PC board (1) has components (2), a compatible I/O adapter
connector (3), plus a header connector (not shown) to terminate the
cable (4) leads.

      The circuits are designed on the PC board (1) so the signal
lines of one port are present on the other port when diagnostic tests
are performed by the I/O adapters (5) (for example, local loopback
tests).

      The other end of the wrap assembly (6) has an equivalent
connector (3).  The cable leads are terminated directly to the
connector (3) per the manufacturers instructions.

      Both ends are encased in a plastic overmold or boot (7) for
protection.  Thumbscrews (8) retain the wrap assembly to the mating
I/O connectors (see the figure).
