Package Content
The Atlona HDMI 4 by 2 Switcher is wonderful for watching media on multiple displays
without the need to move devices. Great for home theatres with two mirrored video outputs,
such as: flat panel display and video movie projector. The Atlona switcher supports two HDMI
100Mbps Ethernet ports for HDMI Ethernet Channel (HEC) and two Audio Return Channels,

1. Place your switcher within 60 feet (18.29 meters) of your displays.
Note: If using the supplied IR remote control, remember you need to be within 23 feet (7
meters) and within a 60° angle of the infrared receiver.
2. Connect the HDMI cables to your sources and the switcher’s inputs labelled HDMI IN.
a. If the auto switching feature is turned on (through RS-232) the AT-HD4-V42 will
change inputs to the source that was powered on last. The source will switch to the
previously turned on device when the current input is turned off.
Note: The Ethernet Channel will not pass to your devices if the HEC feature is not supported or
you are not using the correct HDMI cables.
3. (Optional) Plug the supplied Infrared module into the IR IN port and place the receiver end
somewhere that is within 23 feet (7 meters) of where you will be using remote.
Note: The supplied infrared module will allow you to control the Atlona AT-HD4-V42 when
placed in a cabinet.
4. Plug the power cord into the DC 5V labelled port and then plug the other end into the wall.
5. (Optional) Plug the Ethernet cables into the Ethernet ports. If your devices and cables are
HDMI Ethernet Channel compatible you will be able to pass the internet signal through the
HDMI cables.
Note: Please verify that your devices are HDMI Ethernet Channel compatible, most ports will
be labelled HEC for easy identification.
6. (Optional) Plug the Digital (S/PDIF) cable into the S/PDIF port. If you have an audio system
this will allow for 2 channel and multichannel support.
Note: If the Digital Audio is plugged in it will take first priority over the HDMI audio
connection. Neither Dolby TrueHD or DTS-HD Master Audio will work with this option.
a. (Optional) ARC Mode – The Audio Return Channel can be accessed through the
switcher, by reselecting the source you currently have selected (all source lights will
go off). The switcher will then pass through the audio from your video display to
your A/V Receiver as an ARC signal (this will only work with ARC capable displays).
Your video display will pass through audio from either its internal tuner or from any
device plugged into it.
7. Connect the ends of the HDMI cables into the video displays and the other ends into the
ports labelled HDMI OUT on the switcher.
8. Press the power button (on either the remote or the switcher) to turn on the
AT-HD4-V42.
9. (Optional) If using the RS-232 connection, plug the cable into the switcher, then your
computer or third party control.
Note: You can purchase the RS-232 cable at: http://www.atlona.com/
a. PC control will need a hyperterminal program. If you do not have one then you will
need to download or purchase one and follow their instructions for the program’s
installation.

RS-232
To set up the RS-232 hyperterminal 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 switcher default:
Bits Per Second: 9600, Data Bits: 8, Parity: None, Stop Bits: 1 and Flow Control: None.
Connection
RS-232 is connected through a 9-pin female D connector. The pins will have functions
associated with them, some will be unassigned.

Command
The command codes are very sensitive, do not change capitalization, spacing, or lettering.

PWON PWON Power on
PWOFF PWOFF Power off
x1AVx1 x1AVx1 Route input 1 to the outputs
x2AVx1 x2AVx1 Route input 2 to the outputs
x3AVx1 x3AVx1 Route input 3 to the outputs
x4AVx1 x4AVx1 Route input 4 to the outputs

AUTOOFF AUTOOFF Turns the auto switching feature off
Status x1AVx1 Displays which input is currently connected to the outputs
Mreset Mreset Returns the switcher to its default settings
VER V0.91a Displays current firmware version
Each command or feedback is terminated with a carriage return.
Note: If the command fails or is incorrect the feedback should be “Command FAILED”
EDID (Extended Display Identification Data)
EDID is the exchange of capabilities between a source and display. This handshake ensures the audio
and video signals sent are supported by both source and display.
The AT-HD4-V42 has 3 EDID modes. Internal picks the highest common audio/visual signal between
the devices and the available EDIDs within the switcher. External selects the highest common
resolution between the current input and the display connected to output 1. Learned saves the EDID
from the current output 1 display and locks it to the output.
Internal EDID
The Internally loaded EDID settings are the most common A/V signals that come standard in most TV
displays and computer monitors. The AT-HD4-V42 will pick the highest common resolution between
the devices.
External EDID
External EDID is the highest common audio/video signal between the current source device and
display. It is useful for devices with uncommon resolutions that are not stored internally.
Learned EDID
Learned EDID allows for a display’s EDID to be saved to the switcher. The saved EDID will not reset
when power cycled or the display is replaced.
NOTE: Hold the EDID button for 5 seconds to save a new EDID to memory.
