ETC GigaPix troubleshooting

Common GigaPix 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.

• Getting GigaPix onto wireless DMX (City Theatrical Multiverse)

  Likely cause: SHoW ID, SHoW Key, universe, and antenna type must all match the transmitter or the fixture simply never sees data - and the failure looks identical to a dead module.

• GigaPix fans too loud for a studio or quiet theatre cue, or output dropped unexpectedly

  Likely cause: Two places set fan mode and DMX wins, so a fixture can sit in Studio - and therefore 20% down on output - with a front panel that says Standard.

• GigaPix flickers, drops out, or behaves erratically on DMX - especially the last fixture in the run

  Likely cause: Unterminated DMX runs reflect the data signal back down the line and corrupt it.

• GigaPix ignores console colour, or macros/pixel content override the base look (the modules fight each other)

  Likely cause: All three modules drive the same nine LED engines, so the fixture needs an explicit arbiter.

  Step-by-step fixGet the fix →

• GigaPix LEDs and motors shut down on their own when the console is off or DMX is pulled

  Likely cause: Crews read a hibernating fixture as a dead fixture and pull it from the rig.

• GigaPix real-world output, beam and colour numbers for plotting and rental spec

  Likely cause: Rental and plot decisions turn on candela at angle and on the honest distinction between the 16,700 lm sphere figure and the 7,574-15,777 lm field figures.

• GigaPix shows a "Pan" error on the display after power-up, or the head will not home / find position in pan

  Likely cause: The lock is the only field-fixable cause, so rule it out first; errors persist in error history until cleared, so a stale code can look like a live fault.

• GigaPix shows a "Tilt" error after power-up, or the head will not tilt / hunts on tilt

  Likely cause: Crews routinely miss the tilt lock because vertical looks like the "off" position on many fixtures; on GigaPix vertical means locked.

• GigaPix shows a "Zoom" error, or zoom will not move through the 4.5-55 degree range

  Likely cause: ETC documents only three causes for Zoom: indexing-circuit malfunction, defective stepper/driver IC, or the zoom wheel not parked at default after reset.

• GigaPix strobes or banding shows up on camera

  Likely cause: GigaPix offers three flicker-control frequencies (2.4, 16, 25 kHz).

  Step-by-step fixGet the fix →

• GigaPix will not pass DMX out to the network, or will not convert network data to DMX for downstream fixtures

  Likely cause: Techs habitually use one moving light as a protocol gateway for the next.

  Step-by-step fixGet the fix →

• How much DMX footprint does a GigaPix need, and why do fixtures overlap addresses in the patch

  Likely cause: Address collisions on GigaPix are almost always because the Pixel module was enabled in Compound mode after the plot was addressed, silently adding 36 channels per fixture.
