The same connector does not guarantee the same interface
An interface record needs the pin assignment, signal direction, supply relationship and connected device, not just the connector shape. Drawings should state the viewing direction. Photographs help with location but do not replace pin or wiring definitions. Use consistent identifiers across equipment, cables and files.
Document the operating states
After checking the physical connection, review power-up, standby, running, shutdown and fault states. Specify when commands may be sent, what feedback confirms completion and how communication failures or inconsistent states are recovered. This gives hardware and software a shared basis for verification.
Give files a revision and changes a destination
Drawings, firmware, software and configuration files should have revisions and identify the equipment or sample they apply to. A change record should explain what changed, which interfaces are affected and whether older files remain applicable. A clear handover directory is easier to use than scattered message attachments.
Make the handover reviewable by the receiver
Before handover, check that files open, links work, connection drawings match the equipment and the receiver has the required environment. List unfinished items separately, with the responsible party and an agreed next step.
