Compact synchronous & asynchronous controller with four gigabit ports — indoor and outdoor versions.
LDU4100 packs the same synchronous & asynchronous DNA into a more compact brief: four gigabit Ethernet outputs, each driving up to 650,000 pixels — 2.6 million pixels in total.
An optional 3G modem keeps remote screens connected where wired internet never reaches, making it the practical controller for distributed signage networks.
