Safety Ring Switch from Sonoss is, as the name suggests, an Ethernet switch used in a ring configuration. For big events where double ring Ethernets are often employed, the switch has a response of less than 35 millisecs to an interruption. Luminex Products, who make the switch, also showed a prototype lighting desk - Hummingbird - a 'soft' desk where any function of the desk can be subordinated to any module in an Ethernet system.
