Introduction This guide contains information about the Extron DSC 301 HD Digital Scaling Converter with instructions for experienced installers on how to install, configure, and operate the equipment. In this guide the terms “digital scaler” and “scaler” are used interchangeably and refer to the DSC 301 HD model. This section gives a basic description and the key features of the DSC 301 HD scaler.
Key Features Inputs • Video — The DSC 301 HD has the following connectors: one HDMI connector, one 15-pin HD connector for RGBHV or HD/SD component video, and one BNC connector for composite video. • Auto-Image setup — When activated, the unit automatically detects the resolution of the incoming video signal and sets the total pixels, phase, active pixels, and active lines, as well as the horizontal and vertical starting points.
• HDCP Visual Confirmation — This provides a full screen green output signal when HDCP-encrypted content is transmitted to a non-HDCP compliant display, providing immediate visual confirmation that protected content cannot be viewed on the display. • HDMI to DVI Interface Format Correction — Automatically enables or disables embedded audio and infoframes, and sets the correct color space for proper connection to HDMI and DVI displays.
• Front panel security lockout — This feature can block all front panel control, or limit front panel to input selection only. All functions however, are available through RS-232 control. • RS-232 control port — Enables the use of serial commands for complete control and configuration or integrated into a control system. Extron products use the SIS™ Simple Instruction Set command protocol, a set of basic ASCII code commands that allow for quick and easy programming.
Rear Panel Connections This section describes how to connect cables to a DSC 301 HD scaler. Rear Panel Cabling The illustration below shows the rear panel features of the DSC 301 HD. DSC 301 HD POWER POWER 12V 12V 1.0A 1.0AMAX MAX 22 11 1 DSC DSC301 301HD HD INPUTS INPUTS 33 11 22 VIDEO VIDEO RGB/R-Y,Y,B-Y RGB/R-Y,Y,B-Y HDMI HDMI AUDIO AUDIO 2 3 4 5 Figure 1.
d Input 3 — Connect an HDMI source to this HDMI connector. Audio from the HDMI input can be de-embeded from the HDMI source. This allows the user to choose to select audio either from the HDMI input or the analog audio 3.5 mm TRS inputs. The default selection is 2-channel digital audio from the HDMI input. Secure the HDMI input to the HDMI connector c using the LockIt bracket as follows: 1. Plug the HDMI cable into the panel connection. 2.
Operation This section of the manual discusses the operation of a DSC 301 HD device, and is divided into the following sections: • Front Panel Overview • The DSC 301 HD Menu System — Configuration and Adjustments • Front Panel Lockout (Executive Modes) Front Panel Overview 1 4 11 22 33 HDCP HDCP ADJUST ADJUST INPUT INPUT CONFIG CONFIG OUTPUT OUTPUT Extron Extron MENU MENU 3 2 Figure 2.
The DSC 301 HD OSD Menu System — Configuration and Adjustments Scaler configuration and adjustments can be performed by using the On-screen Display (OSD) menu or the Extron Simple Instruction Set (SIS) of commands (see the “SIS Communication and Control” section). The OSD menu can be seen on the connected display device. OSD Menu Navigation Using Front Panel Controls Menu button — Press the Menu button to activate or deactivate the main menu.
To navigate and use the OSD menu: 1. Press the Menu button once to open the menu on the display, The menu opens with the Quick Setup submenu (see figure 3). Figure 3. OSD Menu — Quick Setup Submenu 2. If the desired submenu is not showing, use the Adjust knobs ({, [) to navigate to the desired menu. 3. Press the Enter button to access the submenu. 4. Rotate either Adjust knob to cycle through the submenu to the desired option. 5. Press the Enter button to access the submenu item. 6.
IN2: EDID — Select this to match the output rate or to set a discrete EDID (see the table on page 18 for EDID data). IN3: EDID — Select this to match the output rate or to set a discrete EDID (see the table on page 18 for EDID data). Output Resolution — Select this to set the resolution and refresh rate for the output. There are 83 factory installed output resolutions and rates, and 3 custom user defined blocks. See the table on page 18 for details.

Input Submenu This submenu allows the user to configure the active input. Figure 7. OSD Menu — Input Submenu Auto-Image — Select this to start a one-time Auto-Image on the active input. Input x: Input Format — Select this to change the active input format. NOTE: Only input 2 can be changed (RGB or YUV). Input 1 is always composite video and input 3 is always HDMI. Input x: Film Mode — Select this to turn Film Mode on (auto detect mode) or off.
Output Submenu This submenu allows the user to configure the output. Figure 8. OSD Menu — Output Submenu Resolution — Select this to change the resolution and refresh rate for the connected output display (see the table on page 18 for details). HDMI Format — Select this to set the HDMI output format.
Input AFL — Select this to turn the Extron Accu-Rate Frame Lock (AFL) on or off. When enabled, this mode locks the output vertical refresh rate to the vertical refresh rate of the currently selected input using Accu-Rate Frame Lock technology. This ensures no frames of the input are repeated or dropped due to frame rate conversion.
An Example of Audio Setup using an Extron Cable Cubby® • The Extron cable cubby has three video inputs (composite, RGB, and HDMI), and are connected to the DCS 301 HD, inputs 1-3. • A single 3.5 mm TRS audio cable is connected to the analog TRS 3 input on the DSC 301 HD. • Configure input 1 and input 2 to use audio from the analog TRS 3 input. • Configure input 3 to LPCM-2Ch Auto to use digital audio when present, or when not present, to use analog TRS 3.
Screen Saver and Timeout — Select the screen saver to mute the video output when no active video is detected. The screen saver can be set to a black (default) or a blue background for a specific (time-out) duration, before the output sync is disabled. The time-out duration can be set to Never (default), or to any duration from 1-500 seconds. The screen saver option allows connected display devices to go into a low power standby mode when the DSC 301 HD has no active input.
Communication Submenu This submenu allows the remote port settings for the unit to viewed. No adjustment is possible via the OSD menu. Figure 13. OSD Menu — Communication Submenu Device Submenu This read-only menu allows the user to view the current device status. Figure 14.
The viewable device status information is: • device internal temperature (in degrees F and C) • the current active input details (resolution, signal format, and total lines) • output resolution and refresh rate and output format • AFL status (locked or disabled) • HDCP status (input status and HDMI output status) • Display Info (resolution and refresh rate) • Firmware build details Resolutions and Refresh Rates In addition to the 83 factory rates, there are also three custom, user-defined or captured rates
Custom EDID or Custom Output Resolution The user has the ability to capture EDID or upload EDID files to make custom EDID available for emulation on inputs, or for the generation of custom output resolutions. The user can import a 128 or 256 byte EDID “.bin” file from a PC or can capture the EDID from an attached sink (display) device.
SIS Communication and Control The DSC 301 HD can be configured and controlled via a host computer or other device (such as a control system) attached to the rear panel RS-232 connector or the front panel USB port. Control is made using the Extron Simple Instruction Set (SIS) of commands. Commands can be entered using a Telnet application such as the Extron DataViewer, available at www.extron.com. See the DataViewer Help file for use. This section describes SIS communication and control.
Error Responses When the DSC 301 HD receives a valid command, it executes the command and sends a response to the host device. If the unit is unable to execute the command because the command contains invalid parameters, it returns an error response to the host.
