Instruction Manual – DXLink Fiber Transmitters and Receivers
USER EDID 1
This EDID is empty until an EDID is programmed/uploaded by using DGX Configuration software (see page 143). It
can be programmed either through the switcher and Input board that the Transmitter is connected to or through the USB
Program port on the Transmitter. If the command is sent to load USER EDID 1 prior to any EDID being programmed,
then the previously loaded EDID will remain on the input.
USER_EDID_MODIFIED
This EDID is empty until a preferred timing is set through the SEND_COMMAND: VIDIN_PREF_EDID. For a table
listing supported input resolutions that can be made the preferred EDID timing, see page 130. This EDID modifies the
current active EDID by replacing the preferred timing with the format desired.
MIRROR OUT 1
This EDID mirrors the downstream EDID of the connected DXLink device. When connected to a DXLink Input Board,
this EDID will be the same as USER EDID 1.
* When the Transmitter is connected directly to a Receiver, the EDID from the RX’s connected display will be
presented to the digital input. This is only supported when both of the units are Duplex hardware operating in full
Bidirectional Mode with the return data path established.
MIRROR_OUT_LOCAL
This EDID is the digital EDID from the last sink attached to the local out port. This can only be applied to the HDMI
input. This EDID does not persist over a power cycle. If you wish this EDID to persist, you can load it onto the HDMI
input using the SEND_COMMAND: VIDIN_EDID-MIRROR_OUT_LOCAL, read it using DGX configuration
software from the HDMI input and then writes it back to the HDMI input. The EDID will then be saved as
USER EDID 1.
Note:
A Duplex Transmitter in Bidirectional Mode will use the ALL RESOLUTIONS default EDID until it
receives information from the display device (or SEND_COMMAND or DGX Configuration Software) that
requires a different EDID. Since a Transmitter in Unidirectional Mode (or connected to a Receiver or Input
Board in Unidirectional Mode) has no return data path to receive EDID information from the display device,
the EDID will always be the default EDID, ALL RESOLUTIONS, for the Digital input.
AMX EDID Library
An AMX EDID Library is available at www.amx.com (search for EDID Library). This library provides EDID files that
can be used with AMX products. A report is provided for each EDID file, which describes the EDID features in detail, in
order to assist you in selecting the most appropriate EDID for your system needs.
Check the Library to determine if one of the custom EDID files meets your needs. (The custom EDID files
are variants of base/standard EDIDs.)
DGX Configuration Software can be used to reprogram the EDID on the input port with one of the .edid files
provided in the EDID library (see page 143).
