  • Bidirectional RS-232 port for universal display control — The MLC 104 IP has a dedicated port for communicating with virtually any projector or flat panel display via IR or RS-232. Control drivers can be downloaded or created using the intuitive software.
  • IP Link® Ethernet monitoring and control — An IP integration technology developed by Extron specifically engineered to meet the needs of professional AV environments that enables the MLC 104 IP to be controlled and proactively monitored over a LAN, WAN, or the Internet.
  • Discrete ON and OFF display power controls — Simplify system operations and eliminate the need for an external display remote.
  • RS-232 port for MLS - MediaLink Switcher support — For controlling an optional Extron MLS - MediaLink Switcher.
  • Configurable buttons — Can be assigned to trigger a variety of functions such as selecting an input or sending a serial command or IR command signal.
  • Macro capability — Any button can be configured to execute multiple actions through the serial and IR control ports. For instance, the touch of a single button could trigger commands to turn on the display, select the display's RGB input, and select an input on the MLS - MediaLink Switcher.
  • Tri-color, backlit, easy-to-label buttons — Can be customized for each installation and provide easy operation for presenters in low-light environments.
  • Inactivity timer for display shutoff — Adjustable timer controls automatic shutdown to conserve energy, prevent plasma burn-in, or extend projector lamp life.
  • Front panel security lockout — When the security lockout mode is engaged, the MLC 104 IP's front panel becomes inoperable unless a user-defined PIN number is entered. No controller functions can be activated.
  • Volume control with volume indication for display or MLS - MediaLink Switcher — Allows for convenient, centralized control without additional remotes. The five LEDs provide a clear indication of the current audio setting.
  • Optional wireless remote control — When used in conjunction with a DVCM 50 Stand-Alone, Dual-Function IR Learning Control Module, the MLC 104 IP can be controlled via IR using an IR 452 Remote Control with an IR Link Wall-Mountable IR Signal Repeater or IRL 20 IR Signal Repeater.
  • Optional SCP 104 Secondary Control Panel, part # 60-672-xx — Duplicates the MLC 104 IP's front panel buttons and offers a second access point within a room.
  • 7.25 MB flash memory
  • Available in black, white, or RAL9010 white
  • Mounting options — There are a variety of optional mounting kits available for installing the MLC 104 IP virtually anywhere, including walls, lecterns, or tables.
  • Includes MR 200 two-gang mud ring
  • External universal ENERGY STAR® qualified power supply available, part # 70-775-01 — Provides worldwide compatibility, low power consumption, and reduced operating costs.
