The Lightware Protocol #3 (LW3) is implemented in almost all new Lightware devices (matrix switchers,
signal extenders and distribution amplifiers) since 2012. The protocol is APSC

-based and all commands
are terminated with a carriage return (Cr, '\r') and line feed (Lf, '\n') pair.
t is organized as a tree structure
that provides outstanding flexibility and user-friendly handling with 'nodes', 'properties' and 'methods'. The
Advanced View of the Lightware Device Controller software is the perfect tool for browsing and learning how
the LW3 protocol can be used in practice.

▪
▪ The nodes are separated by a slash ('/') character.
▪ The node name can contain the elements of the English alphabet and numbers.
Use the TCP port no. 6107 when using LW3 protocol over Ethernet.
▪
▪ When a command is issued by the device, the received response cannot be processed by the CPU.
▪ The node paths describe the exact location of the node, listing each parent node up to the root.
