Model Version Description Part #
Annotator 300 Annotation Processor with DTP Extension 60-1316-01

The Extron Annotator 300 is a high performance, hardware-based annotation processor that allows a presenter to draw, point, or type over live presentations using a touch display, graphics tablet, or a keyboard and mouse. The HDCP-compliant Annotator 300 includes HDMI and DisplayPort inputs, a universal analog video input, and three simultaneous outputs including two HDMI and a DTP® twisted pair output. It also features advanced Extron video signal processing with a high performance scaling engine and fast, reliable switching. The DTP twisted pair output extends HDMI and bidirectional control signals to a DTP receiver over a shielded CATx cable up to 330 feet (100 meters). The Annotator 300 offers a wide range of annotation tools and controls, all easily accessible by the presenter using an intuitive on-screen GUI.

Create Real-Time Annotations with a User-Friendly Interface

User-friendly graphical icons and menus provide quick access to essential annotation tools for drawing freehand or lines, adding rectangular or elliptical shapes, typing text, highlighting an area of the presentation, and pointing to objects on-screen, with various customization tools. A presenter can also isolate a specific area of the presentation for emphasis by creating a spotlight with the image darkened around it. Additional annotation options include the ability to use a touch flat-panel display as a whiteboard, zoom and pan within the image, and freeze a live image. Annotated images may be captured and saved to internal memory, a removable USB flash drive, or a network location. These images can also be printed using a network printer.

Compatible with Popular Touch Displays and Graphics Tablets

Annotating over live video or presentations is easy using common touch displays, graphics tablets, as well as any standard keyboard and mouse. A total of 25 devices can be connected via USB hubs. The Annotator 300 is ideal for collaboration applications requiring simultaneous on-screen annotation from two users.

High Performance Video Processing

The Annotator 300 features an advanced scaling engine that can scale HDMI, DisplayPort, RGB, component, and standard definition video signals to a common high resolution output. It provides high performance deinterlacing of all interlaced signals up to 1080i, and Deep Color processing to deliver optimal image quality. The universal analog video input automatically detects incoming RGB, component video, S-video, or composite video. Automatic 3:2 and 2:2 pulldown detection maximizes image quality for content sources originating from film. The Annotator 300 accepts signals up to 1920x1200 and 2K, plus DisplayPort input signals at resolutions up to 2560x1600. The output can be set for various resolutions up to 1920x1200, including 1080p/60 and 2K.

The Annotator 300 provides three simultaneous outputs – two HDMI and one DTP that enable three displays to be driven simultaneously. Selectable FILL and FOLLOW modes are available to set the preferred aspect ratio of the output. FILL mode provides full screen output, while FOLLOW mode preserves the original aspect ratio of the input signal.

Built for Digital Video Integration

To simplify integration of HDMI sources and displays, and to help ensure optimal system performance and dependability, the Annotator 300 features three Extron-exclusive technologies: EDID Minder®, Key Minder®, and SpeedSwitch®. EDID Minder manages EDID communication between the display device and input sources to ensure that the correct video formats are displayed reliably. For HDMI signals with protected content, Key Minder authenticates and maintains continuous HDCP encryption between input and output devices to ensure quick and reliable switching. With SpeedSwitch Technology, the Annotator 300 delivers exceptional, virtually instantaneous switching speeds for HDCP-encrypted content.

Integrated Digital Twisted Pair Extension

The Annotator 300 includes one DTP twisted pair output. This output can be used to extend HDMI, analog audio, and bidirectional control signals to a DTP 230 or DTP 330 receiver in a remote location, such as behind a flat-panel display on a wall or above a ceiling-mounted projector. DTP 230 and DTP 330 receivers are available in compact, low-profile enclosures or decorator-style wallplate versions to suit the installation requirements of a specific application. The Annotator 300 can also be integrated into a larger AV switching system with a DTP-enabled switcher or matrix switcher, such as the Extron IN1608 or DTP CrossPoint 84.

When the Annotator 300 is paired with a DTP 330 receiver, HDMI, analog audio, and control signals can be extended up to 330 feet (100 meters) over a single shielded CATx cable. With a DTP 230 receiver, signals can be extended up to 230 feet (70 meters).

The DTP twisted pair output includes additional convenient, integrator-friendly features designed to help simplify installation. Bidirectional RS-232 and IR signals can be inserted from a control system and transmitted over the single shielded CATx cable together with the video, enabling control of a display. The Annotator 300 can also send power to the DTP receiver over the same shielded CATx cable, streamlining system design and installation.

HDBaseT-Compatible Output

The DTP output can be configured for compatibility with an HDBaseT-enabled display to send digital video and embedded audio, plus bidirectional RS-232 and IR signals up to 330 feet (100 meters) over a shielded CATx cable.

Configurable Main and Confidence Outputs

The outputs of the Annotator 300 can be configured as separate Main and Confidence outputs, with the ability to selectively control visibility of the annotations and on-screen menus. One of the three outputs can be used as a dedicated Confidence output for the presenter, while the remaining two serve as Main outputs for the audience. The Confidence output can be configured so that only the presenter can view the annotation GUI. The presenter can also use the Confidence output to preview annotations before making them live through the Main outputs for the audience.

Multiple Options for Control and Operation

The Annotator 300 features front panel controls for quick access to functions. Remote configuration and control are available via USB, RS-232, and Ethernet, plus contact closure to control input switching. The Annotator 300 can be configured using Extron's PCS - Product Configuration Software with a user-friendly GUI that is very easy to navigate. This allows for expedited setup and commissioning, as well as real-time operation and monitoring. The Annotator 300 can also be monitored using the integrated Web interface. Housed in a 1U, full rack width metal enclosure, the Annotator 300 can be easily integrated into many environments.
