Installation
IP Conguration
The AT-HDR-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. If the AT-HDR-CAT-4ED is unable to detect a DHCP server within
15 seconds, then the unit will use a self-assigned IP address within the range of 169.254.xxx.xxx/16. If this
occurs, refer to Auto IP (APIPA) Mode (page 14).
Use an IP scanner, along with the MAC address on the bottom of the unit, to identify the unit on the network. If a
static IP address is desired, the unit can be switched to static IP mode.
NOTE: When switching between DHCP and static IP mode, the AT-HDR-CAT-4ED will retain the last
assigned IP address until it is changed manually (static IP mode) or assigned a new IP address by the
DHCP server.
Setting the IP Mode
Using the Front Panel
1. Make sure the AT-HDR-CAT-4ED is powered.
2. Connect an Ethernet cable between the LAN port of the AT-HDR-CAT-4ED and the Local Area Network (LAN).
3. Press and hold the POWER button for approximately 15 seconds. Release the POWER button once all the front-
panel LED indicators begin to ash. The number of ashes will indicate the currently selected IP mode. Refer to

Controlling Audio Output
The AT-HDR-CAT-4ED features a separate AUDIO OUT port on the rear panel. This port provides de-embedding and
conversion of two-channel LPCM audio streams to analog audio. Audio output volume can be controlled using API
commands or the built-in web server.
IMPORTANT: The AT-HDR-CAT-4ED will only de-embed two-channel LPCM audio. Down-mixing
mulitchannel audio to two-channel audio is not supported. In addition, video must accompany the
audio at all times. This product does not support audio-only (“free-run” mode) output.
Audio Port Wiring

RS-232 Control
The AT-HDR-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 passthrough RS-232 / 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-HDR-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 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.

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-HDR-CAT-4ED will use only TxD, RxD, and GND
signals when communicating with a control system or computer. Refer to connection instructions on the next page.

Device Operation
Pass-through mode
In pass-through mode, RS-232 commands are passed-through the AT-HDR-CAT-4ED, 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 PortHDBaseT Port
RS-232 / IR 1HDBaseT OUT 1
RS-232 / IR 2HDBaseT OUT 2
RS-232 / IR 3HDBaseT OUT 3
RS-232 / IR 4HDBaseT OUT 4
1. Connect the RS-232 cable from the control system to the desired RS-232 / IR port on the AT-HDR-CAT-4ED.
Refer to RS-232 Port Wiring (page 25) for instructions on preparing the cable.
2. Connect a category cable from the desired HDBaseT OUT port to a receiver. In this example, the HDBaseT
cable is connected from HDBaseT OUT 2 to a compatible 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.
