Keys with programmable LCD tops and programmable backlighting are grouped in a self-contained 3 x 4 cluster. The cluster is equipped with an Ethernet interface, and is allocated a unique IP address and UDP port number. Key images are sent to the cluster via UDP frames from a server. All key presses are broadcast via on the network. Any number of these clusters can be deployed on the same network because of the unique IP addresses. The clusters are typically used in man-machine interface consoles.
