Chauvet ÉPIX D4 IP troubleshooting
The Chauvet ÉPIX D4 IP problems live-event techs bring to Ask Roadie most (also called EPIX D4, EPIX D4 IP, EPIX Mapping System, ÉPIX Mapping System). Pick your symptom, or describe your own in plain words, and get the likeliest fix first, with the manual page when there is one.
Common ÉPIX D4 IP errors & problems
What techs run into most, and what's usually behind it. The step-by-step fix for your exact unit is in Ask Roadie.
- Step-by-step fixGet the fix →
A port shows ERROR (not OVERLOAD, not SHORT)
Likely cause: ERROR is the catch-all for a damaged/faulty port or a faulty internal connection.
- Step-by-step fixGet the fix →
A port shows OVERLOAD on the Port State screen and that port is dead
Likely cause: Each port has a fixed 48 VDC current budget.
- Step-by-step fixGet the fix →
A port shows SHORT on the Port State screen
Likely cause: The drive isolates a shorted port rather than letting it take down the whole supply.
- Step-by-step fixGet the fix →
Changes to universe, address, IP, or subnet do not stick after leaving the menu
Likely cause: The drive stages edits and only commits them on Save Changes, so a tech who sets an address and immediately backs out to check the home screen sees the old value and assumes the unit is faulty.

Conflicting published specs for ÉPIX D4 IP weight, power and temperature
Likely cause: The product page appears to carry pre-production figures while the Rev.
- Step-by-step fixGet the fix →
Display shows KLSTR FAULT
Likely cause: The D4 IP runs a KLSTR.one subsystem as a distinct processor from the drive control board, so the fault can originate in the PC app, the subsystem, or the master PCB - and the escalation order goes cheapest to most expensive.
- Step-by-step fixGet the fix →
Display shows OVER TEMPERATURE FAULT and all output is dead
Likely cause: The drive self-protects by disabling output before heat damages the supply.
- Step-by-step fixGet the fix →
Display shows SENSOR FAULT and output is disabled
Likely cause: The drive cannot trust its thermal protection if the sensor is bad, so it fails safe by disabling all output rather than risking running hot blind.

Drive came off a cold truck into a warm venue - safe to power it up?
Likely cause: Condensation on energised electronics causes immediate shorts.
- Step-by-step fixGet the fix →
Fast onboard diagnosis without a laptop - what the 5 home screens tell you
Likely cause: Global Color plus Test Patterns bypass the console entirely - if the strips respond there, the drive and the 4-pin runs are healthy and the problem is upstream in the network or the desk.
- Step-by-step fixGet the fix →
Flicker, dropout, or dead pixels at the far end of a long EPIX Line run
Likely cause: End-of-run flicker on a 48 V constant-voltage pixel system is nearly always voltage drop from undersized conductors or over-length runs, not a data problem - which is why the spec sets a power-conductor gauge separate from the data gauge.

Getting ÉPIX Line fixtures patched on the console without hand-building the rig
Likely cause: MVR/GDTF removes the hand-patching step that used to dominate EPIX prep, and Art-RDM gives a way to change drive settings from FOH without walking to the rack.
