Read Error Message
A Read Error message will appear if the Transmitter has never been programmed with a valid/custom EDID or if the unit
has been programmed with a corrupted EDID. A Read Error message will also appear when attempting to read the EDID
after sending a FACTORYAV SEND_COMMAND, which re-initializes the USER EDID 1 EEPROM and resets the
VIDIN_EDID setting to ALL RESOLUTIONS (which is AMX_HDMI1v3__Standard for HDMI and
AMX_VGA1v2__Standard for VGA).
Note: When a Transmitter is connected to a DXLink Fiber Input Board, the input board will override the "ALL
RESOLUTIONS" EDID and load the last stored EDID.
Writing EDID Data to a DXLink Fiber Transmitter's Input Connector
When DGX Configuration Software discovers and displays "Inputs" for an DXLink Fiber Transmitter, the input is
numbered twice to allow for reading from either an HDMI source device or a VGA (HD-15) source device.
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 Library" of EDID files will be available on at www.amx.com in conjunction with a future
firmware release.
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 131.
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 SEND_COMMAND
VIDIN_EDID-USER EDID 1
Important: You can revert to the factory default EDID for the HDMI or HD-15 input by using the
SEND_COMMAND
for HDMI and AMX_VGA1v2__Standard for VGA).
