N3 Receiving Card

Overview

N3 is a mini receiving card developed by Colorlight for lighting screens. N3 adopts a small-sized hardware design and its size is 70×24mm, suitable for light bar screens, net screens, dot lights and special-shaped screens. It can effectively save space and reduce the difficulty in designing screen structure. The N3 receiving card can be widely applied in such scenarios as urban beautification, landscape lighting, and shopwindow dressing.
 

Features

• Loading capacity: 8192 pixels
• Supports 24 sets of RGB data serial output or 8 sets of RGB data parallel output
• Supports signal extension
• Supports brightness and chromaticity point-by-point calibration
• Supports any scan mode from static up to 1/16 scan
• Supports firmware backup and safe firmware upgrade
• Support loop backup
• Supports arbitrary offset of data group
• Supports the display image of single card to rotate 90, 180 or 270 degrees so as to achieve the display of special-shaped screen
• Signal transmission requires only 2 core twisted pair, and the peripheral cascade connection line supports going from one input to one output
• Fully enclosed design, effectively shielding electromagnetic wave, allowing the display to pass EMI testing
• Compatible with the relay card of Colorlight
