How this DMX-512 UV Bar simulator works
The simulator mirrors a real LED UV bar fixture across all 8 DMX channels of its 8-channel mode. Drag any fader and the on-screen output updates live — same channel allocations, dim curves and strobe behaviour as our hardware. Use it to plan cues without a console, demo a fixture to a client, or see how the three UV zones blend at different intensities before you spec a rig.
DMX-512 channel layout (8-channel mode)
| CH |
Function |
Range |
| 1 | Main brightness | 0–255 (0–100%) |
| 2 | Grid 1 brightness | 0–255 (0–100%) |
| 3 | Grid 2 brightness | 0–255 (0–100%) |
| 4 | Grid 3 brightness | 0–255 (0–100%) |
| 5 | Strobe | 0–214 synchronised (slow → fast) · 215–255 random (slow → fast) |
| 6 | Dimmer mode | 0–255 — four fade in/out curves |
| 7 | Refresh frequency | 0–255 — selectable LED refresh rates |
| 8 | Fan | 0–127 fan runs for cooling · 128–255 fan off |
The B18xUV offers three channel modes, selectable from its LCD menu: 1-channel (single master brightness), 3-channel (Grid 1, Grid 2 and Grid 3 brightness independently) and 8-channel as listed above. This simulator reproduces the 8-channel mode. All three grids are UV — the fixture carries 18 UV-A emitters and no RGB channels. DMX addresses run from 1 to 508, and the bar also speaks RDM, so address, channel mode and device name can be set remotely from a compatible console instead of walking the truss.
