Id Pushbutton Functions; Hdmi Rx Scaling Button And Scaling Modes - AMX DXLink Multi-Format Wallplate Instruction Manual

ID Pushbutton Functions

The ID Pushbutton is located on the right front of the modules, on the left edge of the Wallplate TX, and on the front of
the Decor Wallplate TX.
The ID Pushbutton can be used to perform four types of initial configuration settings:




The functions performed depend on when and for how long the ID Pushbutton is pressed and held. For complete
ID Pushbutton information, see page 67.
Note: ID Pushbutton functions can also be implemented using Telnet commands (see page 108).

HDMI RX Scaling Button and Scaling Modes

The Scaling button is located on the front of the HDMI Receiver Module. Pressing the Scaling button cycles the module
through the three scaling options: Bypass, Auto, and Manual.



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 HDMI RX with the Scaling button (see instructions below), with DGX
Configuration Software, or with SEND_COMMANDs (see page 80).
To set the scaling option (mode):
1.
Press the Scaling button on the HDMI RX 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 the Transmitters; progressive is only supported out
of the Receiver unless it is in the Bypass mode, which is non-scaling.
Auto Mode
At initial power up, the HDMI RX defaults to the Auto scaling option.
Note: When the output cable is disconnected from the HDMI RX or if no EDID can be found on the
destination device, the last used Scaling Mode LED will be ON. In either case, the HDMI RX 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
1280x1024 @ 60 Hz 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 @ 60 Hz. This default resolution can be changed in two ways:



Toggle between DHCP and static IP addressing
Assign a device address
Reset the factory default settings
Restore the factory firmware image
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.
Use the SEND_COMMAND VIDOUT_RES_REF to set the resolution and refresh rate (for details, see
page 80).
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 HDMI RX.
