The SL−1N is a master room controller that can operate over Ethernet (LAN) with control ports that include two bidirectional RS−232, two IR and three relay. It controls devices such as scalers, video displays, audio amplifiers, DVD players, sensors, screens, shades, door locks, and lights. Multiple Kramer Ethernet gateways can be used to add remote I/O ports.

The SL−1N includes a KNET™ connector interface which enables access to the master controller from auxiliary room controllers such as control keypads. The SL−1N can also provide power to auxiliary room controllers via the KNET™ connectors.
