Product overview
The Linsn RV998 LED receiving card has eight integrated HUB75 connectors and outputs sixteen RGB data groups. It supports brightness calibration, single-card color-space conversion, configuration readback and network-cable testing. The attached manual describes hardware V5 and specifies a 256 × 512-pixel capacity.

Match the loading specification to the card
The original page’s larger loading figures do not match the attached hardware V5 manual. Confirm the card revision and supported module configuration before choosing a screen size; do not treat these values as interchangeable.
The integrated HUB75 connections remove the need for a separate HUB board for this interface. Check the pin assignment, scan mode and driver IC against the screen’s configuration file before replacing a receiver.
The manual describes high-refresh and high-grayscale operation without a numerical rating. Actual settings should be established for the connected modules rather than inferred from the maximum pixel dimensions.


Frequently asked questions
1. How many HUB75 outputs does RV998 have?
The RV998 integrates eight HUB75 connectors and supports sixteen RGB data groups.
2. What is the RV998 maximum pixel capacity?
The attached V3.0 manual for hardware V5 specifies 256 × 512 pixels. The original product page says 256 × 1024 or 512 × 512, so confirm the revision and configuration before selecting the card.
3. Can the RV998 read back its configuration?
Yes. Configuration-file readback and network-cable BER testing are both listed in the model-specific manual.
4. What voltage and power does the documented RV998 use?
The hardware V5 manual lists DC 4.5–5.5 V input and 3 W rated power consumption.
