Downloads, wiring notes and the numbers behind the listings
The documents a technician actually asks for: cabinet wiring diagrams, card pinouts, power sizing sheets and the software versions that match older screens.
Power supply sizing sheet
Module average load, supply derating and cabinet ambient in one table. The arithmetic behind every power quote we send.
Read the method SelectorPixel pitch and viewing distance
Pitch against minimum viewing distance, with the camera-work multiplier and the cost step between pitches.
Open selector NoteCabinet flatness and visible seams
Why a 0.3 mm step reads as a shadow line at five metres, and the test to run before accepting a container.
Read the note NoteNovastar or Colorlight
How to pick a control platform on software tolerance, spares and local support rather than on image quality.
Read the note TemplateParts list template
A one-page format for sending a BOM: part, model, quantity, pitch, destination port. Ask and we send the spreadsheet.

- One HUB75 ribbon per module on a 1/32 scan board; two 16P ribbons on most 1/16 outdoor boards. Count the connectors on the module before ordering cable.
- Keep ribbon under 500 mm where possible. Beyond that, signal integrity drops and the far end of the chain flickers at low grey.
- Power the cabinet from one end, not both, unless the supply has a current-sharing bus. Feeding both ends of a chain from one supply creates a loop.
- Ground the cabinet frame to the building earth, not to the power supply negative. The two are not the same point.

Send the cabinet model and the card you plan to use. We will send the wiring diagram that matches that combination, not a generic one.
