Installation Guide
AT-DISP-CTRL
1. Connect an HDMI cable from the HDMI OUT port to the display device.
2. Connect an Ethernet cable, from the PoE LAN port, to a PoE-capable network switch.
3. OPTIONAL: Connect an serial cable from the RS-232 port to the display device. Refer to
RS-232 / IR Connector (page 3) for wiring information.
4. OPTIONAL: Connect an IR emitter from the IR OUT port and place the emitter within range
of the IR window on the display device. Refer to RS-232 / IR Connector (page 3) for
wiring information.
5. OPTIONAL: Connect an Ethernet cable from the LAN port to the display device.
6. Connect an HDMI cable from the source device to the HDMI IN port on the AT-DISP-CTRL.
Once the source device is connected and the AT-DISP-CTRL is congured properly, the AT-
DISP-CTRL will turn on the connected display device.
NOTE: The AT-DISP-CTRL is powered over Ethernet (PoE) using a PoE-capable
network switch. If a PoE-capable switch is not available, then connect the
included power supply to the FW port.
Installation
By default, the AT-DISP-CTRL will use CEC* commands to send turn-on/turn-o messages
to the display device. CEC is delivered over the HDMI cable that is connected to the display
device. Commands can also be sent over RS-232, IR, or Ethernet (IP). If CEC control is not
desired, using one of the following connection methods:
HDMI to Display
Ethernet (control) to Display
RS-232 (control) to Display
IR (control) to Display
Ethernet (PoE) from Network Switch

*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.
