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. Input AFL mode will cause glitches and/or interruptions in the output sync when a new input is selected, or when a new signal has been routed to the selected input, as the DSC 301 HD locks to the new vertical refresh rate.

If no input signal is detected (AFL disabled), or if locking to the input signal is not possible, a free running pixel clock is generated by the DSC 301 HD.

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.

Input x: Auto-Image — Select this to turn the per-input Auto-Imaging mode on or off. Auto-Image automatically attempts to size and position the image to Fill (or Follow the native aspect ratio of the input) the screen every time a new input signal is detected.

When enabled, Auto Image mode is activated by switching physical inputs on the DSC (e.g. IN2 to IN3), or by any interruption in input sync, even if the same input resolution is detected (e.g. disconnecting and reconnecting the same input), or by a power cycle.

Input x: Aspect Ratio — Select this to set the per-input Aspect Ratio to FILL (fills the entire output raster) or to FOLLOW (follows the native aspect ratio of the input).

When in Fill mode, if an Aspect Ratio adjustment for a single input rate is desired, the correct size and center can be manually set up under Picture Controls (Image Size and Position).

When in the Follow mode, each input rate will be displayed with its native aspect ratio (4:3, 5:4, 15:9, 16:9, 16:10) with the correct letter box or pillar box settings visible under the Image Size and Center Picture Controls.

Input x: Auto Memory — Select this to turn the per-input Auto Memory on or off.

The DSC 301 HD has 32 Auto Memory locations per input, for RGB/YUV and HDMI inputs. YUV and RGB signals on the same input have unique Auto Memories; for example 720p YUV and 720p RGB are stored with unique Auto Memory settings.

Auto memory locations store the same Input Config and Picture Control values as an Input Preset, except for Input Type, Preset Name, Film Mode, or Audio Gain/Att.

Overscan — Select this to set the overscan mode (0%, 2.5% or 5.0%) per input type.

This zooms and crops SMPTE inputs to mask edge effects and ancillary data that are common in broadcast signals. Issuing an Auto-Image with overscan enabled, runs an Auto Phase routine (YUV and RGB only) and centers and sizes the input according to table values.

NOTE: Overscan is valid only on SMPTE input rates (NTSC, PAL, SECAM, 480p,

576p, 720p, 1080i, or 1080p, or 2k).

Auto Switch — Select this to turn the Auto Switch mode on or off, and to set the priority.

The Auto Switch setting allows for basic, unmanaged, input switching based on the presence of active input signals. Auto Switch mode options are:

• disabled (off)

• setting priority to “high to low” (input 3 to input 1)

• setting priority to “low to high” (input 1 to input 3).

Factory Reset — This resets the device back to factory defaults (retains current firmware).

NOTE: “FACTORY RESET” is displayed on the OSD for 1 minute after the reset to

allow time for the display device to sync with the DSC 301 HD output.

To reset the DSC 301 HD to factory setting, including original shipped firmware, press and hold the Enter button for 20 seconds while applying power. The message “FIRMWARE RESET” is displayed on the OSD to indicate the reset is completed.

When a FIRMWARE RESET is applied, the loaded current firmware is deleted and only the factory firmware remains on the device.

Figure 15. Resolution and Refresh Rates

When a new custom rate is captured or uploaded, the On-screen Display (OSD) dynamically updates with the new rate for that custom slot. For example, if a custom 480p EDID is uploaded to slot C1, the LCD would read “C1: 720x480”. These three custom slots are shared between custom output resolutions (based on preferred timings 1 block) and custom EDID tables, which can be assigned to any input.

DSC 301 HD • Operation 18

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. This EDID can then be saved and stored in one of three custom EDID slots, which are then available for custom EDID emulation or custom output rate generation (custom rate based on the EDIDs preferred timings). These functions are available via SIS (see the table on page 18).

Power Save

The DSC 301 HD has a power save mode that allows the user the ability to put the unit into a low power state, via SIS command (see “Power Save Mode” on page 31). This state effectively cuts the power consumption of the DSC in half. While in this mode, no audio or video input processing takes place, the HDMI output and all front panel LEDs are disabled.

The user has the ability to exit Power Save mode via any front panel button press, or by disabling Power Save via SIS command.

The Power Save state is entered instantly after the associated command has been received, but 5-10 seconds are required to resume from the Power Save state.

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 @60Hz.

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

Press and hold inputs 1 and 3 simultaneously for approximately 3 seconds. The output rate becomes 1024x768 @60 Hz. Again, press and hold inputs 1 and 3 simultaneously for another 3 seconds and the output rate becomes 720p @60 Hz.

NOTE: The output rate will subsequently toggle between 1024x768 @60 Hz and

720p @60Hz each time inputs 1 and 3 are simultaneously pressed and held down for 3 seconds.

Front Panel Lockout (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. This mode can only be enabled and disabled using SIS commands.

NOTE: When Executive mode 1 is implemented and a front panel button is

pressed, an OSD message indicates that Executive Mode 1 is enabled.

Executive mode 2 (enabled) — The front panel is locked except for input switching. This mode can be enabled and disabled using front panel buttons or SIS commands.

To prevent accidental changes to settings, press the Menu and Next buttons simultaneously for 2 seconds to enable front panel lockout mode (Executive Mode 2). An OSD message is displayed indicating Executive Mode 2 is enabled.

To unlock it via the front panel, press the Menu and Next buttons simultaneously for 2 seconds. An OSD message is displayed indicating Executive Mode 2 is disabled.

DSC 301 HD • Operation 19

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. Topics that are covered include:

• Host to Scaler Communications

• Commands and Responses

The scaler uses a protocol of 9600 baud, 1 stop bit, no parity, and no flow control and the rear panel remote port RS-232 captive screw connector has the pin assignments as shown at right.

Host-to-Scaler Communications

SIS commands consist of one or more characters per field. No special characters are required to begin or end a command sequence. When the DSC 301 HD determines that a command is valid, it executes the command and sends a response to the host device. All responses from the scaler to the host end with a carriage return and a line feed

(CR/LF = ]), indicating the end of the response character string (one or more characters).

REMOTE

RS-232

Tx Rx G

Scaler-initiated Messages

When a local event such as a front panel selection or adjustment takes place, the DSC 301 HD scaler responds by sending a message to the host. No response is required from the host. Example scaler-initiated messages are listed here.

• In X! All ] (where X! is the input number during an input switch).

• Reconfig ] The DSC 301 HD sends this response when a new signal is detected.

• HplgO X@ ] The DSC 301 HD sends this response when a hot plug event on

output X@ is detected.
