Loading note: the product information lists both 512 × 512 at 60 Hz and a 260,000-pixel overview figure. These are not numerically identical. Confirm the supported load for the actual module and interface configuration before finalizing a screen design.
Calibration, Monitoring and Backup
- Smart setup and screen-wiring configuration support different module wiring arrangements, with data-group exchange and offset adjustment.
- The built-in display test checks module brightness uniformity and flatness.
- With a grayscale correction system, point-by-point brightness and color calibration supports bright/dark line adjustment. Independent RGB gamma adjustment is also supported.
- Monitor card temperature and voltage without external monitoring devices, and record running time.
- Store configuration parameters in the factory area for restoration. Receiver-card backup supports switching to the backup card if the primary card fails.
- For LED boards with Flash memory, correction coefficients can be stored and read back.

Frequently Asked Questions
Which scan modes does the HD-R5S Plus support?
It supports static modules and scan modes through 1/128, including conventional driver chips and mainstream PWM chip modules.
What is the maximum load of the R5S Plus?
The load-range specification is 512 × 512 at 60 Hz, depending on interface count and module resolution. The overview also gives 260,000 pixels; confirm the applicable configuration rather than treating these figures as identical.
Can the receiving card rotate the displayed image?
Yes. Rotation in 90-degree steps is supported: 0°, 90°, 180° and 270°.
Does it support pixel calibration?
Yes. In conjunction with the grayscale correction system, it supports point-by-point brightness and color correction, bright/dark line adjustment and independent RGB gamma adjustment.
What cable type and distance are specified?
The listed communication distance is within 80 m using Cat5e or Cat6 network cable.
