Colorlight N6 Mini Receiving Card

Colorlight N6 Mini Receiving Card is a mini receiver card developed by Colorlight for outdoor fixed displays and lighting screens. With a size of 66mm×25.4mm, N6 is suitable for light bar screens, net screens, dot lights and special-shaped screens, and it can effectively save space and reduce the difficulty in designing screen structure. Additionally, the N6 receiver card can work in a wide range of temperature, which is up to 75℃, and thus it is applicable to harsh outdoor environment.

Colorlight N6 Mini Receiving Card supports 100BASE-T and 1000BASE-T Ethernet modes. The N6 card can be connected in series with 1000BASE-T Ethernet cables, or be used with the R8 distributor. It supports the two or four-cable 100BASE-T cascading mode when used in conjunction with the distributor.
