Two-Output HDMI to HDBaseT™ Distribution Amplier
AT-UHD-CAT-2
The Atlona AT-UHD-CAT-2 is a 4K/UHD HDMI to HDBaseT distribution amplier featuring pass-
through HDMI input connections, two HDBaseT outputs, and display control capability. Each
output transmits AV and control signals up to 230 ft. (70 m) @ 1080p and 130 ft. (40 m) @ 4K/
UHD. Features include 4K/UHD @ 60 Hz with 4:2:0 color subsampling, HDCP 2.2 compliance,
EDID management, and PoE for powering remote receivers. A wide variety of consumer
displays may be controlled by the UHD-CAT-2 using CEC. Designed for commercial distribution
applications, the UHD-CAT-2 is control system-friendly and integrates with any TCP/IP, RS-232,
or IR control system and features a 1U, half-rack width enclosure with external, international
power supply. The UHD-CAT-2 is ideal for use with the AT-UHD-EX-70C-RX HDBaseT receiver,
AT-HDVS-200-RX HDBaseT receiver and HD scaler, or AT-HDVS-SC-RX HDBaseT receiver and
4K/UHD scaler.

Installation Guide
AT-UHD-CAT-2
The AT-UHD-CAT-2 provides three RS-232 ports. The RS-232/IR MASTER port is used to
control the AT-UHD-CAT-2 using a control system or other DTE equipment. RS-232/IR 1 and
RS-232/IR 2 ports are used in conjunction with the HDBaseT OUT 1 and HDBaseT OUT 2
ports. RS-232 data is passed through over the the respective HDBaseT OUT port (zone) to a
sink device connected to a PoE-compatible the receiver. This step is optional.
1. Use wire strippers to remove a portion of the cable jacket.
2. Remove at least 3/16” (5 mm) from the insulation of the RX, TX, and GND wires.
3. Insert the TX, RX, and GND wires into correct terminal using one of the included 5-pin
captive screw connectors.
4. Tighten the captive screws to secure the wires in place. Do not over-tighten or use hightorque devices to prevent damage to the connector block.
NOTE: Typical DB9 connectors use pin 2 for TX, pin 3 for RX, and pin 5 for
ground. On some devices functions of pins 2 and 3 are reversed.

Installation Guide
AT-UHD-CAT-2
1. Connect an HDMI cable from a UHD/HD source to the HDMI IN port.
2. Connect an HDMI cable from the HDMI OUT port to a display (sink) device.
3. Connect up to two Ethernet cables from the HDBaseT OUT ports to compatible PoEcapable receivers.
4. Connect an Ethernet cable from the LAN port to the Local Area Network (LAN). This step
will be required in order to access the built-in web server.
5. Connect the included power supply to the DC 48V connector and connect the power cord
to an available electrical outlet.
Installation
Optional
6. Connect an RS-232 or IR cable from the control system or other DTE device to the RS-232/
IR ports:
• MASTER RS-232/IR
Connecting to this port will provide direct control of the AT-UHD-CAT-2. Control can
be performed using either RS-232 or electrical IR.
• RS-232/IR 1 or RS-232/IR 2
Each of these ports is associated to the respective HDBaseT OUT port. This allows
RS-232 pass-through zone control of a display (sink) device that is connected to a
PoE-compatible receiver. Control can be performed using RS-232 or electrical IR.
By default, the AT-UHD-CAT-2 is set to DHCP mode, allowing a DHCP server (if present) to assign the unit an IP address. If a DHCP server is not found within 15 seconds, then the unit will be
placed in Auto IP mode and use a self-assigned IP address within the range of 169.254.xxx.xxx.
If DHCP or Auto IP mode are not desired, the unit can be placed into static IP mode by using the
POWER button on the front panel.
IP Conguration
Press and hold the POWER button for approximately 15 seconds. Once the LOCK LED indicator
begins to ash, release the POWER button. The number of ashes will indicate the currently
selected IP mode:
