Trace a lighting fault through its controller, Ethernet or DMX path, node mapping and fixture addressing. HJ checks the saved channel and universe baseline before changes, isolates supported causes and retests the affected cues; Art-Net transport is not proof of correct fixture personalities or wiring.
Conceptual planning path — not an as-built drawing or project photograph.
Tell us the fault and your location. Diagnostic attendance, repairs, parts and any travel charges are confirmed with you before work.

It sits in Architectural Lighting Service under Architectural Lighting. The final deliverable is shaped by the intended outcome, the installed or proposed environment and the interfaces that must be owned, supplied, integrated and tested.
Controller/node/fixture models, show-file version, universe/address/channel map, DMX and network route, symptom timing, recent changes and safe diagnostic window.

Controller/node/fixture models, show-file version, universe/address/channel map, DMX and network route, symptom timing, recent changes and safe diagnostic window.
Map fixture personalities, DMX addresses, Art-Net or other supported transport, controller outputs and power to the approved zone schedule. The show-file owner and electrical, structural and safe-access parties retain their assigned responsibilities.
Verify agreed channels, dimming, colour, cues and schedules at the actual viewpoints. Rehearse approved stop/restart and loss-of-control behaviour in a safe window; preserve field protection and record any discontinued or mismatched equipment.
Retain fixture/driver IDs, address/channel and network map, versioned show files where owned, authorised change list and witnessed visual tests. Document safe access, specialist responsibilities, remaining limits and approved follow-up.
HJ coordinates assessment, engineering, installation, integration, testing and lifecycle support only for the scope recorded in the quotation. ISD handles catalogue, model, datasheet, supply and availability enquiries. Customer, consultant, builder and appointed-specialist responsibilities remain explicit.
Regulated or multi-discipline work proceeds only after site assessment and confirmation of the competent, qualified or appointed persons, approvals, safe isolation and responsibility required for that scope.
Installed platform, authorised ownership, parts compatibility and serviceability are checked before any repair or restoration outcome is proposed.
See related systems, how HJ installs them, and support for equipment you already have.
Use the answers as a planning boundary; site conditions and written scope remain decisive.
Network reachability alone does not prove universe routing, DMX addressing or fixture personality. Compare the authorised map and show file, isolate the supported path and verify the required channels and cues before restoring service.

Tell us what the system is, what is going wrong or what you want checked. HJ will confirm the work needed, explain who is responsible for what, and agree the next step with you before any work starts.
