*Consumer Electronics Control (CEC): Atlona has confirmed proper CEC functionality with several current models of Samsung, Panasonic, and
Sony displays. However, it is not guaranteed that CEC will work with all displays. Many manufacturers do not support the CEC “off” command,
and older displays use proprietary commands. Atlona only supports displays that use the CEC command structure defined in HDMI 1.2a. It is
recommended that dealers request an evaluation product from Atlona, before designing a system using the CEC protocol. If this is not possible,
then other control methods will need to be considered, in order to control displays using Atlona products.

Installation
IP Configuration
The AT-UHD-CAT-4ED is shipped with DHCP enabled. Once connected to a network, the DHCP server (if available),
will automatically assign an IP address to the unit. Use an IP scanner, along with the MAC address on the back of
the unit, to identify both the unit and its IP address on the network. If a static IP address is desired, the unit can be
switched to static IP mode. Use one of the following procedures to switch between DHCP and static IP mode.
The default static IP address of the AT-UHD-CAT-4ED is 192.168.1.254.
If the AT-UHD-CAT-4ED is unable to detect a DHCP server within 15 seconds, then the unit will set all IP settings to
zero.
IMPORTANT: If the AT-UHD-CAT-4ED is receiving a DHCP IP address, and the IP mode is changed
to static, then Telnet and web server communication will be lost.
Setting the IP Mode
1. Make sure the AT-UHD-CAT-4ED is powered.
2. Connect an Ethernet cable between the LAN port of the AT-UHD-CAT-4ED and the Local Area Network (LAN).
3. Press and hold the POWER button for approximately 15 seconds. Release the POWER button once the LOCK
LED indicator begins to flash. The number of flashes will indicate the currently selected IP mode.

Device Operation
EDID Management
The AT-UHD-CAT-4ED provides two EDID modes: INT and LEARN. The default EDID mode is INT mode. In this
mode, the AT-UHD-CAT-4ED will automatically create an EDID based on the capabilities of all connected displays.
INT mode is recommended for the best results when the capabilities of all connected displays are unknown. INT
mode can also be used to select any of 16 EDID presets. Refer to Selecting EDID Presets (page 16) for more
information on this topic. LEARN mode can be used to capture an EDID from any sink device. Once the EDID is
learned, it will be used by the connected source device to determine what video and audio formats can be sent to
the sink device.
Learning an EDID using the Front Panel
1. Power the AT-UHD-CAT-4ED.
2. Connect an Ethernet cable from the HDBaseT OUT 1 port on the AT-UHD-CAT-4ED to a receiver (e.g. AT-UHDEX-100CE-RX).
3. Connect an HDMI cable from the receiver to the display (sink) device. Make sure that the sink device is powered.

Device Operation
RS-232 Control
The AT-UHD-CAT-4ED provides two methods of RS-232 control: Pass-through mode and control mode. The master
RS-232 / IR port, allows the unit to be directly controlled using a control system. In addition four pass-through RS232 / IR ports allow sink devices, at the viewing location, to be controlled using a control system.

RS-232 is serial data protocol that allows Data Terminal Equipment (DTE) devices,
system, to communicate with Data Communication Equipment (DCE) devices, such as the AT-UHD-CAT-4ED or a
display. Although IP control is available, RS-232 still plays an integral part of many control systems.
The 25-pin D-type connector (DB-25) was defined as the RS-232 standard, but is now commonly implemented in a
nine-pin (DE-9) connector package. Each pin is numbered, as shown below.

Determining the Port Type
Most DTE devices provide a male connector, while DCE devices have a female connector. However, this is not
always the case. If the port type is unknown, then a multimeter can be used to determine whether the port is DTE or
DCE:

1. Turn on the multimeter and set it to measure DC voltage.
2. Connect the positive and negative leads to pins 3 and 5, respectively.
3. Check the voltage reading:
If the voltage is between -3 V DC and -15 V DC, then the device is DTE.
Otherwise, it is DCE.

Cable Assembly
When connecting a DTE device to a DCE device, a straight-through cable should be used. A straight-through cable
is wired in such a way that the pins on one side of the cable are connected to the corresponding pins on the opposite
side of the cable, as shown in the table below. However, the AT-UHD-CAT-4ED will use only TxD, RxD, and GND
signals when communicating with a control system or computer.

1. Connect the RS-232 cable from the control system to the desired RS-232 / IR port on the AT-UHD-CAT-4ED.
Refer to Cable Assembly (page 20) for instructions on preparing the cable.
2. Connect an Ethernet cable from the desired HDBaseT OUT port to a receiver. In this example, the HDBaseT
cable is connected from HDBaseT OUT 2 to an AT-UHD-EX-100CE-RX receiver (the RS-232 cable is connected
from the control system to the RS-232 / IR 2 port).
3. Connect an RS-232 cable between the display (sink) and the receiver.
4. Adjust the RS-232 settings on the control system to match the requirements of the sink device. For example, if
the RS-232 settings for the display device are 9600, N, 8, 1, then set the control system to the same settings.
If the control system and sink device settings do not match, then RS-232 control will not function.

*Consumer Electronics Control (CEC): Atlona has confirmed proper CEC functionality with several current models of Samsung, Panasonic, and
Sony displays. However, it is not guaranteed that CEC will work with all displays. Many manufacturers do not support the CEC “off” command,
and older displays use proprietary commands. Atlona only supports displays that use the CEC command structure defined in HDMI 1.2a. It is
recommended that dealers request an evaluation product from Atlona, before designing a system using the CEC protocol. If this is not possible,
then other control methods will need to be considered, in order to control displays using Atlona products.

Cable Termination
Atlona recommends EIA/TIA-568-B termination. Connector type and size is very important to ensure extenders work
correctly. Always use the matching cable type with the correct RJ45 connector.
•
CAT5e cables should use only CAT5e RJ45 connectors
•
CAT6 cables should use only CAT6 connectors
•
CAT6a cables should use only CAT6a connectors
•
CAT7 cables should use only CAT7 connectors
Using the wrong size connectors may result in interference causing loss of signal.
WARNING: EZ RJ45 connectors are not recommended with HDBaseT extenders. Doing so may result
in interference with audio and video transmission.
