Mounting and Cabling

Step 1 — Mounting

Turn off or disconnect all equipment power sources and rack mount the

DSC 301 HD unit with either an optional shelf mounting brackets (RSU 126 or

129, RSB 126 or 129) or optional furniture mounting brackets (MBU 125); see

ﬁgures 1 and 2 at right. When rack mounting, an optional rack false face plate

(RFF 052) can be ﬁtted on top of the low proﬁle DSC, improving the overall look

within the rack.

Step 2 — Connecting inputs

Connect inputs from video sources to the applicable connectors marked “Inputs”:

bComposite video, cRGB, R-Y, Y, B-Y, dHDMI (with or without embedded

digital audio).

Connect inputs from analog audio sources to the TRS inputs e.

Step 3 — Connecting outputs

Connect a suitable output display device to the connector marked “Output”

(see fabove) for HDMI output with embedded audio.

Step 4 — Connecting control devices

RS-232 — For serial RS-232 control, connect a host computer or control

system to the 3-pole captive screw connector g.

RS-232 protocol (default values): 9600 baud, 1 stop bit, no parity, 8 data bits,

no ﬂow control.

USB — Connect a host computer or control system to the front panel mini USB

port for conﬁguration and control via Extron Conﬁgurator software.

Step 5 — Connecting power

DC power connector — Plug in a 12 VDC, 1A max power source into this

2-pole captive screw connector a.

DSC 301 HD • Setup Guide

•Flash amber when the video output has been disabled (such as when in sync mute of screen saver mode).

eMenu navigation buttons (Menu, Enter) — These buttons allow navigation through the OSD menu system of the DSC 301 HD.

fAdjust knobs — These are used with the menu navigation buttons to adjust the device settings and picture controls.

Setting the Front Panel Locks (Executive Modes)

The DSC 301 HD has three modes of front panel security lock that limit the operation of the unit from the front panel.

Executive mode 0 (disabled) — The front panel is fully unlocked. This is the default setting.

Executive mode 1 (enabled) — The front panel is completely locked. Can only be enabled and disabled using SIS commands, or

Extron Conﬁgurator software. See the online DSC 301 HD User Guide or the rear page of this guide for SIS commands.

Executive mode 2 (enabled) — The front panel is locked except for input switching.

Configuring the DSC 301 HD

DSC 301 HD devices can be conﬁgured through a host connected via RS-232 or USB and using Extron Conﬁgurator software or Extron

Simple Instruction Set (SIS) commands (see rear page for a selection of basic commands).

On-Screen Display (OSD) Menu System

The scaler has an OSD menu consisting of nine submenus that can be accessed

using the front panel Menu and Enter buttons. The Communication menu and the

Device Info menu are read-only menus. The menus are:

• Quick Setup • User Presets • Picture Controls • Input • Output

• Audio • Advanced • Communication • Device Info.

To use any menu:

1. Press the Menu button to access the main menu.

2. Rotate either Adjust knob to cycle through 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 adjust a submenu variable.

Using the OSD menu to configure the DSC 301 HD

zUse the Quick Setup menu to Auto-Image the current input, set video input format, input EDID settings, set output resolution,

audio mute and video test patterns.

zUse the User Presets menu to save the picture control adjustments to each input for later manual recall.

zUse the Picture Controls menu to adjust the image horizontal and vertical position and size, the brightness and contrast

settings, the color and tint levels, and the detail settings as needed.

zUse the Input menu to perform an Auto-Image on the current input, set the video input format and film mode, horizontal and

vertical start, the number of active horizontal pixels and vertical lines, set the total pixels and phase, set HDCP authorization to on or

off, and set the EDID for the current input.

zUse the Output menu to set output resolution, set the HDMI output format, set HDCP notification, and set the Accu-RATE Frame

Lock™ (AFL™) to on or off.

zUse the Audio menu to set and control the

audio mute, the audio input format for the

DSC 301 HD Configuration Software

To conﬁgure the unit using the DSC 301 HD

Conﬁguration software, the software must be

installed (from the included DVD or from

www.extron.com) on a PC connected to the

DSC 301 HD via an RS-232 or via the front panel

USB conﬁg port. Installation creates a

C:\Program Files\Extron\DSC 301 HD

folder and installs the program, a help ﬁle, and an

uninstall utility. After installation, start the program

and either connect via the comm (RS-232) port or

by USB. For full instructions press <F1> or click on

Help>Contents.

Upgrading the Firmware

The onboard ﬁrmware of the DSC 301 HD unit can

be upgraded via the conﬁguration software when

connected via the front panel USB port.

Alternatively upgrades can be made using the Extron Firmware Loader program, which is available online at www.extron.com.

Output Rate Reset

If an output image cannot be displayed due to an incompatible output rate, the DSC 301 HD can be reset via the front panel to either

1024x768 @ 60 Hz or 720p @ 60 Hz.

To set the rate, or to toggle between 1024x768 @ 60 Hz and 720p @ 60 Hz:

Press and hold input buttons 1 and 3 simultaneously for approximately 3 seconds. The output rate becomes 1024x768 @ 60 Hz. Again

press and hold input buttons 1 and 3 simultaneously for another 3 seconds and the output rate becomes 720p @ 60 Hz.

NOTES: The output rate will subsequently toggle between 1024x768 @ 60 Hz and 720p @ 60 Hz every 3 seconds each time inputs 1

and 3 are simultaneously pressed and held for 3 seconds.

Output Scaler Rates

Output rates can be set using the OSD menu or SIS commands. The table below gives the most commonly used rates and the

corresponding SIS variables. See rear page for SIS command input.

The command to set the output rate is EX2!RATE}, where X2! is the output scaler rate as given in the example table below (* = default).

See the DSC 301 HD User Guide (available at www.extron.com) for the full SIS and output scaler rate details.

Audio Input Format Details
