Instruction Manual – DXLink Fiber Transmitters and Receivers

DXLink Fiber RX Scaling Button and Scaling Modes

The Scaling button is located on the front of the DXLink Fiber Receiver. 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 79).

Important: To use SEND_COMMANDs, DXLink Fiber units in Unidirectional or Data Link-lost Mode require a

LAN connection to an Enova DGX Digital Media Switcher via the unit’s ICS LAN 10/100 port (DIP switch #1

and #3 in the ON position).

To set the Scaling Mode:

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 79).

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.

Important: To use ICSP commands, DXLink Fiber units in Unidirectional or Data Link-lost Mode require a

LAN connection to an Enova DGX Digital Media Switcher via the unit’s ICS LAN 10/100 port (DIP switch #1

and #3 in the ON position).

Note: The aspect ratio conversion policy (see page 81) 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.
