In this paper, the authors present a new server system for a wireless LAN DMX to enhance diverse LED lighting effects. In order to enhance the capability to send DMX packets to the large number of DMX client devices, a new WDMX server system is proposed based on a NDIS mini-port driver. Through the NDIS miniport driver rather than raw Transmission Control Protocol/Internet Protocol (TCP/IP) socket, the throughput of the server is increased because header sections of TCP/IP stack are removed. Even, the format of Ethernet frame is modified to use a new type of addressing scheme which can address the devices by universe ID and DMX ID value.
