Choosing the HUB adapter and sender
Select the adapter to match the module interface and verify its pinout, driver IC and scan mode. Smart settings support the screen wiring arrangement, receiving cards can be ordered as needed, and the card includes a test button for brightness-uniformity and module-flatness checks.
Storage rating: the PDF contains a mixed-unit storage-humidity entry (−40~90%℃); confirm the intended rating before specifying storage conditions.
HD-R500S frequently asked questions
Does HD-R500S connect directly to a HUB75 module?
The card has two 50-pin universal HUB interfaces for installing a matching HUB adapter board. The PDF lists HUB75, HUB08, HUB12, HUB320 and HUB40 adapter types; select the correct adapter and pinout for your module.
What is the recommended R500S loading capacity?
The R500S V1.0 PDF specifies 65,536 pixels (128 × 512), with outdoor width ≤256 pixels and indoor width ≤128 pixels. The former R500-labelled text on this page gave different limits and should not be used as the R500S specification.
Does R500S need a sending device?
The R500S specification describes operation with a dual-mode sending box, asynchronous sending card, synchronous sending card or VP-series video processor. It does not substantiate the former R500-labelled claim that a computer can replace the sending device.
How many power inputs does the R500S have?
The V1.0 document lists one DC power interface accepting 4.2–5.5 V. Its two Gigabit Ethernet ports are interchangeable for connecting a sender or another receiving card.
Is the storage environment rating confirmed?
No. The PDF storage-humidity row contains the mixed-unit value “−40~90%℃”. It cannot be treated as a valid humidity or temperature rating; obtain confirmation for storage requirements.
