Planning the screen connection
Match the transfer-board pinout, driver IC and scan mode before connecting modules. Receiving cards can be cascaded and arranged in any order, and smart settings allow the screen routing to match the display module wiring. The running indicator flashes during normal card operation.
HD-R5S frequently asked questions
What is the HD-R5S used for?
The HD-R5S is a compact receiving card for transparent and fine-pitch LED screens. It uses two 120-pin connectors and a matching transfer board rather than onboard HUB75 output sockets.
How many pixels can one HD-R5S control?
The V0.1 specification recommends 256 × 512 pixels. The existing product guidance also calls for a reduced loading width for indoor modules; confirm the module IC, scan mode and layout before setting the final load.
What sending devices are listed in the R5S specification?
The PDF lists A4/A5/A6/A601/A602/A603 players; A3/A30/A30+/C10/C10C/C30/C15/C15C/C35/C35C asynchronous controllers; T901/T901B/T901S synchronous cards; and VP210/VP410 processors. Confirm compatibility for other models.
Which data arrangements does R5S support?
The PDF provides pin definitions for 32 groups of parallel data and 64 groups of serial data. The transfer board and module wiring must match the chosen arrangement.
What supply voltage and operating temperature apply?
A standard 5 V supply is recommended. The PDF gives 4–6 V and −40°C to 85°C in its parameter table, but 4.2–5.5 V and −40°C to 80°C in its technical table. Confirm the supplied revision before relying on the wider limits.
