Overview

The RC−74DL is a 12−button control keypad, with knob and LCD displays. It is a versatile device that connects to powerful control tools: over Ethernet it connects to Kramer's Site−CTRL™, a remote AV control, site management & monitoring system. For extended controlled device capacity it connects to LAN−connected control gateways. For remote keypad control it connects via KNET™ to master room controllers and auxiliary keypads. It flexibly serves either as a standalone room controller, part of multi−units KNET™ system, or part of multi−unit Ethernet system managed by Kramer Site−CTRL™ site management platform. The RC−74DL is ideal for auditoriums and meeting rooms, for convenient control of their complex multimedia systems and other room facilities such as screens, lighting and shades.
