Technical specifications
The linked file is named V0.1, while its document cover identifies V1.0. Values below follow the document content, with overview and recommended loading kept separate.
| Application | Fine-pitch LED display receiving card |
|---|---|
| Module interfaces | 8 × HUB320 |
| Recommended load in parameter table | 128 × 768 pixels; recommended width ≤128 pixels |
| Overview control range | 256 × 512 pixels; confirm applicability separately from recommended load |
| Scan / grayscale | Static to 1/64 / 256–65,536 |
| IC support | Common IC modules and most PWM IC modules |
| Network | 2 interchangeable Gigabit Ethernet ports |
| Cable distance | Super Cat5 / Cat6 within 146 m, as stated in the PDF |
| Power interfaces | 2 DC connections; either one may be used |
| Power supply | 5 V recommended; differing PDF voltage ranges noted below |
| Operating temperature | Parameter table −40°C to 85°C; later °C row −40°C to 80°C with incorrect humidity label |
| Storage temperature / humidity | −40°C to 105°C storage temperature; 0–95% operating humidity |
Check revision-specific limits: the document gives different voltage ranges and upper operating temperatures. Its later °C row is incorrectly labelled humidity. Confirm the applicable limits before finalizing the cabinet specification.
Connection diagrams
Either Gigabit Ethernet port can link to the sender or the next receiving card. Cards may be arranged in any sequence, and screen routing can be configured to match the module wiring.
HD-R320 frequently asked questions
What loading resolution is recommended for HD-R320?
The linked document’s parameter table recommends 128 × 768 pixels with width ≤128 pixels. Its overview separately gives a 256 × 512 control range, which the former page treated as recommended. Confirm the applicable module configuration before using the overview figure.
How many HUB320 outputs does the R320 have?
The card has eight HUB320 ports. Match the module pinout, driver IC and scan mode to the connection drawings before wiring the display.
Which sending devices are listed for R320?
The document lists A4/A5/A6/A601/A602/A603 players; A3/A30/A30+/C10/C10C/C30/C15/C15C/C35/C35C asynchronous controllers; T901/T901B/T901S synchronous controllers; and VP210/VP410 processors.
What power supply should I use?
A standard 5 V supply is recommended. The PDF gives 4–6 V in the parameter table, 4.5–5.5 V at the connectors and 4.2–5.5 V in the technical table. Confirm the supplied revision before using another voltage.
Does R320 include a screen test function?
Yes. The test button is described as supporting brightness-uniformity and module-flatness checks. D1 indicates normal running and D2 flashes rapidly when Gigabit data is recognized and received.
