Product overview
The Linsn RV905H is an LED receiving board with 30-pin module interfaces and selectable RGB data modes. Its attached V1.1 manual documents 16-group RGBR′, 24-group RGB and 28-group RGB output, together with brightness calibration and cabinet monitoring. Loading must be matched to the screen design and card configuration.

Select the correct 30-pin data mode
The normal, 24-group and 28-group modes have different signal assignments. Use the relevant pinout in the manual and match the receiving-card mode in LEDSet or LEDStudio to the module design.
The original listing says 1024 × 256 pixels, while the RV905H V1.1 manual says 512 × 448. These values are retained with their sources and should be checked against the actual revision. The old “479 mm × 1365 mm” size is also not used as a verified installation dimension.
The manual’s model table distinguishes RV905H front-side outputs from RV925H rear-side outputs. Check connector orientation and mounting clearance before substituting cards. Humidity, smoke and LCD monitoring need additional modules.

Frequently asked questions
1. What connector does RV905H use?
The V1.1 manual provides 30-pin module-output pinouts. Its model table identifies front-side output interfaces and a 90-degree RJ45 orientation for RV905H.
2. What is the RV905H pixel capacity?
The linked manual specifies 512 × 448 pixels, with recommended values depending on screen design. The original page says 1024 × 256, so verify the hardware revision and required loading.
3. Are the 24-group and 28-group RGB modes wired identically?
No. The manual gives separate pinout tables for each mode. Use the matching receiver configuration and module wiring.
4. Which cabinet-monitoring parts are optional?
The humidity sensor, smoke module and LCD monitoring module are separately sold in the manual. Temperature, door, fan and voltage monitoring also require the appropriate cabinet connections.
