*Consumer Electronics Control (CEC): Atlona has conrmed 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 “o” command,
and older displays use proprietary commands. Atlona only supports displays that use the CEC command structure dened 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 Conguration
The AT-UHD-CAT-2 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-2 is 192.168.1.254.
If the AT-UHD-CAT-2 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-2 is receiving a DHCP IP address, and the IP mode is changed to
static, then Telnet and web GUI communication will be lost.
Setting the IP Mode
1. Make sure the AT-UHD-CAT-2 is powered.
2. Connect an Ethernet cable between the LAN port of the AT-UHD-CAT-2 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 ash. The number of ashes will indicate the currently selected IP mode.

Basic Operation
EDID Management
The AT-UHD-CAT-2 provides two EDID modes: INT and LEARN. The default EDID mode is INT mode. In this mode,
the AT-UHD-CAT-2 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 18) 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-2.
2. Connect an Ethernet cable from the HDBaseT OUT 1 port on the AT-UHD-CAT-2 to a receiver (e.g. AT-UHD-EX-

RS-232 Control
The AT-UHD-CAT-2 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 two 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, such a computer or control
system, to communicate with Data Communication Equipment (DCE) devices, such as the AT-UHD-CAT-2 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 dened 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.

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.
Voltage levels between -3 V and -15 V DC represent a logic “1”.
Voltage levels between +3 V and +15 V DC represent a logic “0”.

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-2 will use only TxD, RxD, and GND signals
when communicating with a control system or computer.

1. Identify the DE-9 connector that will be attached to the control system or computer (DCE) equipment.
2. Remove the DE-9 connector at the opposite end of the cable with wire cutters.
3. Remove at least 1” of the cable insulation to expose each of the nine wires.
4. Locate a multimeter and set it to the “continuity” function.
5. Attach one of the leads from the multimeter to pin 2 on the DE-9 connector.
6. Take the other lead and probe each of the wires on the opposite end of the cable. When the wire connected to
that pin is detected, the multimeter will emit an audible tone. Once this occurs, identify the current wire, and
move it to the side.
7. Repeat step 6 for pin 3 and pin 5 on the DE-9 connector.
8. Group the remaining wires and pull them aside. Electrical tape can be use to secure the wires to the outside of
the RS-232 cable.
9. Remove at least 3/16” (5 mm) of insulation from the TxD, RxD, and GND wires.

Pass-through mode
In pass-through mode, RS-232 commands are passed-through the AT-UHD-CAT-2, transmitted over HDBaseT to a
receiver unit, and then to the display (sink) device. Note that each RS-232 / IR port is assigned to an HDBaseT OUT
port. This assignment is xed and cannot be changed, as shown in the table below.
RS-232 / IR Port HDBaseT Port
RS-232 / IR 1 HDBaseT OUT 1
RS-232 / IR 2 HDBaseT OUT 2
1. Connect the RS-232 cable from the control system to the desired RS-232 / IR port on the AT-UHD-CAT-2.
Refer to Cable Assembly (page 22) 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-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 conrmed 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 “o” command,
and older displays use proprietary commands. Atlona only supports displays that use the CEC command structure dened 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.
