ID Pushbutton Functions
The ID Pushbutton is located on the right front of the Receiver Module.
The ID Pushbutton can be used to perform four types of initial configuration settings:
Toggle between DHCP and static IP addressing
Assign a device address
Reset the factory default settings
Restore the factory firmware image
The functions performed depend on when and for how long the ID Pushbutton is pressed and held. For complete ID Pushbutton
information, see page 40.
NOTE:
ID Pushbutton functions can also be implemented using Telnet commands (see page 67).
Receiver Module Scaling Button and Scaling Modes
The Scaling button is located on the front of the Receiver Module. Pressing the Scaling button cycles the Module through the three
scaling options: 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 choose the resolution it needs (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 Module 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 Receiver with the Scaling button (see instructions below) or with SEND_COMMANDs (see
page 49).
To set the scaling option (mode):
1.
Press the Scaling button on the Receiver once or twice until the LED for the desired scaling option 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 Transmitters; progressive is only supported out of Receivers unless in
Bypass mode, which is non-scaling.
Auto Mode
At initial power up, the Receiver defaults to the Auto scaling option.
NOTE:
When the output cable is disconnected from the Receiver or if no EDID can be found on the destination device, the last used
Scaling Mode LED will be ON. In either case, the Receiver will continue to hold its output resolution to the last known preferred
resolution until a power cycle or reconnection of a sink with a valid EDID. On power up without a valid EDID, the default preferred
output resolution presented will be 3840x2160,30Hz until a different EDID is detected.
Manual Mode
Manual Mode allows the user to configure the resolution that the video will display through a destination device. Manual Mode
defaults to 1280x1024p,60Hz. This default resolution can be changed in two ways:
Use the SEND_COMMAND VIDOUT_RES_REF to set the resolution and refresh rate (for details, see page 49).
When used as a direct output of an Enova DGX DXLink Output Board, use DGX Configuration Software to set and persist the
Manual scaling resolution for the connector on the DXLink Output Board; the DXLink Output Board sends the scaling
resolution data to the Receiver.
NOTE:
The scaling mode (and the aspect ratio) can also be set on the DXLink Output Board using DGX Configuration Software. The
data is persisted on the board and sent to the Receiver.
Persistence of Scaling Options
The Receiver defaults to “Auto” when power is cycled. The scaling option can be persisted using one of the following methods:
Using the SEND_COMMAND: PERSISTAV (for details, see page 59).
Using DGX Configuration Software to set and persist the scaling option for the connector on the DXLink Output Board on
the Enova DGX Digital Media Switcher; the DXLink Output Board sends the scaling option data to the Receiver.
