Appendix H – EDID Programming
146 Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver
DXLink Equipment and EDID
In cases where the HD-15 (VGA) input on a DXLink Transmitter are used and a resolution incompatibility
exists (or if the source device needs a specific resolution or a limited set of resolutions), the DXLink
Transmitters have the ability to update the VGA EDID emulation file (by updating the EEPROM chip) which
comes preloaded with an AMX VGA EDID set.
The AMX VGA EDID set consists of a number of common EDID settings (for VGA timing details, see
page 131). In most cases, the DXLink Transmitter can be used as is from the factory with no adjustments.
The DGX Configuration Software with EDID programming functionality has been provided for cases where
a user defined VGA EDID set is desired (this
must be a subset of the supported input resolutions shown in
Appendix E; see page 131).
The EDID Programmer view can be used for writing user defined VGA EDID data to the DXLink
Transmitter’s HD-15 input.
Reading and Saving EDID Data from a DXLink TX’s HD-15 (VGA) Input Connector
The DGX Configuration Software reads the EDID data from the USER EDID 1 EEPROM location,
regardless of the VIDIN_EDID setting.
Important: Unless a custom EDID has been previously written to the input, attempting to read the EDID
will result in a Read Error message.
The EDID data can be read to confirm the correct EDID has been programmed.
To read and save EDID data from a DXLink Transmitter:
1.
On the PC, open the DGX Configuration Software and select the EDID Programmer tab.
2. Under Inputs/Outputs on the left, expand the device tree, and select the HD-15 input.
3.
Click Read to read the VGA EDID information currently on the HD-15 input.
The EDID data appears in the EDID read-only field on the right.
Tip: In the EDID Programmer view, the Save to File option under the File menu can be used to save the
EDID information as an .edid file. The saved file can be opened as a text file (from the File menu, select
Open File) and edited or opened and written to an input (click the Write button).
Read Error Message
A Read Error message will appear if the Multi-Format 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 VGA USER EDID 1 EEPROM and resets the VIDIN_EDID setting to
ALL RESOLUTIONS (which is AMX_0500_003).
