Writing EDID Data to a DXLink Fiber Transmitter's Input Connector
This section contains information that applies to DXLink Fiber Transmitters (all Directional Modes) with attached
downstream RX. For procedures that address writing EDID data to a DXLink Fiber board, rather than a Transmitter, see
the Instruction Manual – Enova DGX 8/16/32/64 Digital Media Switchers at www.amx.com.
When DGX Configuration Software discovers and displays "Inputs" for an DXLink Fiber Transmitter, the input contains
two options to allow for reading from either an HDMI or a VGA (HD-15) input.
Use the instructions that follow in conjunction with the EDID Programmer view to write user defined EDID information
to the HDMI or HD-15 input connector on a DXLink Fiber Transmitter. User defined EDIDs are currently available from
technical support. An AMX EDID Library is also available at www.amx.com (search "EDID Library").
To write EDID data to a DXLink Fiber Transmitter input:
1.
Download the EDID set (either HDMI or VGA) from the EDID Library* (or an EDID set provided by technical
support).
2.
On the PC, open the DGX Configuration Software and select the EDID Programmer tab.
3.
Under Inputs/Outputs on the left, expand the device tree, and select the HDMI or HD-15 Input.
4.
From the File menu, select Open File to select the .edid file that was downloaded in Step 1.
5.
Click Write to write the EDID information to the selected Input (either HDMI or HD-15).
6.
Analog (VGA) only – The source must be power cycled to detect the new EDID.
* For information on the EDID Library, see page 142.
Tip: You can confirm that the new EDID data was written to the HD-15 or HDMI input by selecting the input
and clicking on the Read button or by using the
VIDIN_EDID-USER EDID 1
Important: You can revert to the factory default EDID for the HDMI or HD-15 input by using the
VIDIN_EDID-ALL RESOLUTIONS
and AMX_VGA1v2__Standard for VGA).
Note: DXLink Fiber, Duplex Transmitter in Bidirectional Mode only –
connected sink is mirrored to the HDMI Input of the Transmitter by default. Any changes made to that EDID
on the Transmitter (via ICSLan or DGX Configuration Software) will not persist through a change that causes
a reprocessing of video (e.g., power cycle, hot plug of the source or sink devices, or hot plug of fiber optic
cables), but will cause the EDID on the Transmitter's HDMI input to revert to the EDID of the Receiver-
connected sink.
