Overview

The MRV308 is a new receiving card developed by NovaStar. A single MRV308 loads up to 256x256 pixels.

The MRV308 supports pixel level brightness and chroma calibration, which effectively removes color difference, greatly improves display consistency of LED images, and presents finer displays to users.

Software and hardware designs of the MRV308 have fully concerned users'

deployment, operating and maintenance scenarios, enabling easier deployment, more stable operating and more efficient maintenance.

Hardware design:

● Integrates 8 standard HUB75 connectors, which makes the HUB board unnecessary.

●

Adopts the Gigabit Ethernet port, which can connect to the PC.

Software design:

● Supports pixel level brightness and chroma calibration. ● Supports setting of images pre-stored in the receiving card. ● Supports status detection of temperature, voltage, Ethernet cable communication and video source signals. ●

Supports the 5-pin LCD module.

6 Typical Networking The MRV308 is applied to the LED display synchronous system which is generally composed of the LED display, receiving card, LED display controller (optional) and controller peripherals. The receiving card is connected to the LED display over HUB connectors.

The synchronous system requires connecting a computer to display the computer’s images and texts on the LED display. The synchronous system's structure is shown
