  The unit will not do ARC?
 
    • ARC is a feature that has to be activated by pushing the desired input button 2 times or you can send a command “x0AVx1” ending with a carriage return via RS-232.
      • Note: On AT-HD4-V42 ARC is only available on output #1.
      • Note: Unit needs to be running on firmware version VS91GA or higher.

  Unit is not auto-switching?
 
    • With the latest firmware update (VS91GA or higher) the auto switching feature is added, but must be activated via RS-232 command. To turn on auto switching send command “AUTOON” ending with a carriage return; to turn off auto switching send command “AUTOOFF” ending with a carriage return.
      • Note: To find what firmware is on the unit connect via RS-232 and send command “VER” ending with a carriage return and the feedback would be the firmware version.

  What is the difference between the 3 different EDID modes?
 
    • INT: Internal EDID of the AT-HD4-V41/V42
    • EXT: External EDID reads the EDID of the display that is connected to output #1
    • Copy: EDID learn feature that can be done from any output.
      • When using extenders or long HDMI cables, it is recommended to do an EDID learn.

  How do I get the unit into ISP mode for a firmware update?
  With the device unplugged from the wall, hold down the power button and apply power. As soon as the lights turn off release the power button.

  Can you de-embed audio from the S/PDIF out?
 
    • The latest firmware (VS91GA or later) for the AT-HD4-V41/V42 allows the unit to de-embed audio from the S/PDIF.
      • Note: To find what firmware is on the unit connect via RS-232 and send command “VER” ending with a carriage return and the feedback would be the firmware version.
