EDID Set Up
When the matrix is completely connected and turned on it will load the default EDID, which is
the highest common native resolution of the devices. (i.e. With devices connected that range from
720p, 1080p, 2 channel audio, multi-channel audio and 3D, the default resolution will be 720p.
Multi-channel audio and 3D are not available on default unless all devices have these
features.)
There are two options when setting up EDID: Default and Copy. In order to have any options other
than default different EDIDs must first be copied. The AT-H2H-88M can copy up to 4 EDIDs to
memory.
To save an EDID
If you’re having compatibility issues the H2H has a built in EDID management system to enable
specific resolution or audio format to be locked in to a source. The first step is to save an EDID to
the H2H’s built in memory. Save up to 4 unique display EDIDs.

To load a saved EDID
Once the display’s EDID has been saved, the second step is to load it to the input to lock
the EDID to the source. Once the EDID is locked down, the highest resolution and audio
format will be passed.
Example: If Dolby TrueHD is the highest common audio in the saved EDID then no selected
displays with 2Ch audio will receive audio. This is commonly used for AVRs.
Example: If 1080p 3D is the highest common resolution in the saved EDID then only
selected displays with 3D will receive picture from the input the EDID is saved to.

Matrix Settings
When installing or troubleshooting it’s important to verify settings, or be able to come back to
a project and see how it was set up. The AT-H2H-88M has matrix settings viewable through the
front panel. View current I/O settings, firmware version, FPGA version, and the baud rate of the

S/PDIF
The S/PDIF port is used for two audio options, ARC or matrix source audio loop-out. When using
one, the other is disabled. By default the matrix comes with ARC turned off on all ports, this
enables the S/PDIF to loop-out the audio from the matrix source. To switch between ARC and
matrix source audio, ARC must be turned on or off. Enable or disable ARC through RS-232 (see
page 15) or front panel (see below).

Audio Return Channel (ARC)
ARC enables a source connected to a display to route audio to an AVR or zone amp.
Steps
1. Check to be sure the display supports ARC
2. Enable ARC on the HDMI output of the matrix through RS-232 (see page 14) or front panel
(see steps above)
3. Connect the HDMI Matrix output port to the ARC labeled input port on the display
NOTE: The Matrix must be connected to the display’s HDMI ARC input
4. Connect the source to a non ARC HDMI input port on the display
5. Connect the S/PDIF port to an AVR or Zone Amp
NOTE: The S/PDIF port used must be the same output number as the HDMI port connected
to the display

Matrix source audio loop-out
By default the matrix is enabled to de-embed source audio out through the S/PDIF port to an AVR
or zone amp.
NOTE: If audio does not pass through, check to make sure ARC is turned off.
NOTE: HD audio formats are not supported through S/PDIF.

RS-232 Set Up
To set up the RS-232 hyperterminal (if not using 3rd party software) the first thing needed is to
find the RS-232 communications port under the computer’s device manager. Once there right click
the port and select properties. Under the properties menu select the port settings tab and update
the menu to the matrix default: Bits Per Second: 115200, Data Bits: 8, Parity: None, Stop Bits: 1
and Flow Control: None.
Baud Rate
To change the baud rate of the matrix an RS-232 hyperterminal will be needed. Once the RS-232
hyperterminal is set up changing the baud rate will be done with a command line. The baud rate
for the matrix is for matrix control.
Note: Baud Rate must be only 2400, 4800, 9600, 19200, 38400, 57600, or 115200
Command for Matrix baud rate
CSpara[baudrate,data-length,parity,stop-bit] (data, parity, and stop for matrix must be 8,0,1)
For example if you wish to change the baud rate to 38400 the command would look like this:
CSpara[38400,8,0,1]

Updating and Resetting
Updating firmware
At times there will be new firmware to update, fix, or change functionality of products. Atlona has
made this as easy as possible for updating on the job by simply downloading from Atlona.com and
uploading the file onto the matrix.
Needs:
• Verify the current firmware version (See page 11)
• RS-232 9 Pin to 9 Pin cable.
• PC (not compatible with MAC)
• OS that supports USB mass storage devices
• USB A to USB B cable (i.e. AT11008)
To view the current firmware use RS-232 command “Version”.
Preparing the Matrix:
• Unplug the power cable.
• Hold the Cancel button while plugging the power back in.
• Connect the USB B to USB A cable into the Matrix and the Computer.
Updating the Matrix:
The computer should auto detect the connection, if it does not, open the USB device from “my computer”.
• Click open in a new folder. (if auto run detects connection)
• Delete the file in the folder. (there should be only one file, if more delete all files)
• Copy and Paste the new firmware file into the USB folder.
• Unhook the Matrix from the computer.
• Unplug the power cable from the AT-H2H-88M
• Plug the power back in and start the matrix normally. Your update should be complete
If you wish to verify the new firmware, use the RS-232 command “Version” or front panel.
Resetting to factory settings
Atlona understands that settings sometimes get mixed up and at times its just easier to set things
back to factory settings. To make things easier a simple one step reset was created.
To reset the matrix, hold down the buttons 1 and 4 while powering on. If done correctly the matrix will be back to factory settings when it turns on.
