DXLink Fiber RX Scaling Button and Scaling Modes
The Scaling button is located on the front of the DXLink Fiber Receiver, Duplex. Pressing the Scaling button cycles the
RX through the three Scaling Modes: Bypass, Auto, and Manual.
Bypass Mode – allows the video signal to display over the destination device without altering the signal’s
resolution.
Auto Mode (default) – allows the destination device to automatically scale the signal to its preferred or native
resolution (this mode is AMX’s SmartScale
®
Technology in action).
Manual Mode – allows the user to configure the resolution that the video will display through a destination
device.
Selecting a Scaling Mode results in the unit maintaining or altering the source device’s resolution as it is passed along to
the destination device.
The Scaling Mode can be set on the DXLink Fiber RX with the Scaling button (see instructions below), with DGX
Configuration Software, or with SEND_COMMANDs (see page 68).
To set the Scaling Mode:
1.
Press the Scaling button on the DXLink Fiber RX once or twice until the LED for the desired Scaling Mode
illuminates solid green.
Bypass Mode
Bypass Mode allows the video signal to display over the destination device without altering the signal’s resolution.
Note:
Interlaced and progressive video are supported into the Transmitters; the Receiver only supports
progressive out unless it is in the Bypass Mode, which is non-scaling.
Auto Mode
At power up, the DXLink Fiber RX defaults to Auto Scaling, unless a different Scaling Mode has been persisted. In Auto
Mode, the DXLink Fiber RX uses the EDID found on the destination device to automatically determine the best
resolution to scale to. If an EDID is not found on the destination device, the DXLink Fiber RX will revert to a default
resolution of 1280x1024 @ 60 Hz.
Manual Mode
Manual Mode allows the user to configure the resolution that the video will display through a destination device. Manual
Mode defaults to 1280x1024 @ 60 Hz.
The default resolution can be changed in two ways:
Use the VIDOUT_RES_REF SEND_COMMAND to set the resolution and refresh rate (for details, see
page 68).
When used as a direct output of an Enova DGX Switcher’s DXLink Fiber Output Board, use
DGX Configuration Software to set and persist the Manual Scaling resolution for the connector on the
DXLink Fiber Output Board; the DXLink Fiber Output Board sends the scaling resolution data to the
DXLink Fiber RX.
Note:
The aspect ratio conversion policy (see page 70) can also be set on the DXLink Fiber Output Board
using DGX Configuration Software. The data is persisted on the board and sent to the DXLink Fiber RX.
