How to read this profile

Read the exact variant view convention. Schematic layouts do not establish physical positions.

Source-scoped identification facts

Each value retains its exact example, role and measurement axis. Facts from different parts must not be combined into an invented component.

Pins & wiring

Pinout

Choose the exact wiring. Pin numbers follow its stated view; a schematic does not establish physical positions. Check your exact device before wiring.

What the status labels mean
Confirmed
Recorded research passes agree within this variant; this is not independent human review or hardware validation.
Single source
Only one underlying document, or one pass, supports this assignment.
Device-specific
Supported for the named equipment or wiring only. Check your device’s manual.
Unverified
Missing or conflicting evidence. Do not wire from this row.
Not connected
The source explicitly says NC, no contact or no pin for this wiring.

  • P246 VHDCI SCSI 68 — **Partial; agree on comparable single-ended functions** — A's Sun single-ended map and B's LSIU40SE J3/J7 map agree on the data, control, power and return assignments that both verify. Sun's `SP(15)-` on 38 remains unverified; LSI independently calls its own 38 SD15/. Preserve cable-sense behavior at 34/50 rather than flattening it to ordinary ground. A's Sun differential and Intel SE7520JR2 maps remain separate; their differing assignments and Intel's six reserved contacts were not repaired with B's single-ended map. Different primary documents and manufacturers.
  • Historical source-specific map; pin 38 label SP(15)- is unresolved.
  • SP(15)- intended function or correction unresolved in both source variants.
  • Six RESERVED contacts have no verified electrical use or internal connection.
  • No universal SE/LVD/HVD wiring or electrical interchangeability is established. Intel spatial view is also unverified.

View and evidence limits

Numbered pins of LSIU40SE external J3/J7 VHDCI receptacles. Table A.3 establishes pin functions; it does not establish a mating-face left/right layout.

  • P246 VHDCI SCSI 68 — **Partial; agree on comparable single-ended functions** — A's Sun single-ended map and B's LSIU40SE J3/J7 map agree on the data, control, power and return assignments that both verify. Sun's `SP(15)-` on 38 remains unverified; LSI independently calls its own 38 SD15/. Preserve cable-sense behavior at 34/50 rather than flattening it to ordinary ground. A's Sun differential and Intel SE7520JR2 maps remain separate; their differing assignments and Intel's six reserved contacts were not repaired with B's single-ended map. Different primary documents and manufacturers.
  • This complete map is specific to the LSIU40SE single-ended SCSI implementation. LVD, HVD and instrumentation/DAQ uses are unverified; no HD68-only appendix was transferred to VHDCI.
  • Table A.3 is an electrical pin-number table. No explicit mating-face versus termination-side numbered drawing was established.

Unknowns stay unknown.

  • Check the exact device manual before wiring or applying power.

Your next step

Use the detail without guessing past its limits.

Read the connector field note Recognition clues and practical checks.Work through a connection Keep exact equipment and cable requirements separate.
