INTRODUCTION
About
The DXE-CAT-RX3, DXE-CAT-RX3-A, DXE-CAT-RX3C, & DXE-CAT-RX3C-A are a part of the
growing Digital Xtreme Series. This product is different than the typical CAT extender found on
the market today as it not only breaks the price barrier but the feature and usability aspects as
well. Rear mounted connectors provide for a clean professional installation.
The DXE-CAT-RX3 Series is designed to complement the Digital Xtreme Series of HDBaseT
transmitters such as the DXW-2 Series HDBaseT wall plates, DXE-CAT-TX1, DXE-CAT-TX2,
DXM Matrixes, etc. The built in relays are perfect for screen control and the audio amplifier
versions will fill the room with sound when used with the Aurora SKR-22T 360° sound field ceiling
tile speaker. A low cost, highly integrated solution for rolling carts, podiums, and credenzas is
possible with the DXE-CAT family.
Being able to go the distance is important too, and HDBaseT technology helps achieve that. With
a single CAT cable, the DXE-CAT can go up to 328ft 1080p 60Hz 48bit color depth, 500ft 1080p
60Hz 24bit (CAT 6), or 600ft 1080p 60Hz 24bit (CAT 6AShielded) depending on modeland cable.
In addition, the RS-232, IR, & LAN can be sent over the same cable bi-directionally.
Another industry first is the ability to serve up web control pages via LAN to any browser-enabled
device (ex. iPad®, iPhone®, PC, Android®) to take control of the RS-232, IR, and LAN. This is
done with the Aurora LXC control system engine inside, so not only is the DXE-CAT an HDMI
extender receiver unit, but a fully functional autonomous control system that can operate stand-
alone or as a port-expansion for any control system on the market.
Aurora once again is setting the bar for form and functionality at a competitive price.

Front Panel DXE-CAT-RX3 SERIES
Front LED Indicators
IR Out –Blinks when emitting IR to device from IR Port. It is normal to be lit if nothing is plug
into IR port.
IR In –Blinks when receiving IR from IR port. It is normal to be lit if nothing is plug into IR
port.
TX –RS-232 Transmit. Blinking rate and intensity will vary with baud rate.
RX –RS-232 Receive. Blinking rate and intensity will vary with baud rate.
HDBT –Lights when HDBaseT RJ-45 has proper connection between an RX/TX pair. Blinks
when in sleep mode.
HDMI –Will light solid if HDMI is plugged in on both RX/TX and HDCP is present. If no
HDCP LED will blink.
POWER –Lights green when power is present.
STATUS –Will blink steady if unit is working properly.
Front Pin-hole buttons

Rear Panel DXE-CAT-RX3 SERIES
Rear Connections
24V DC –Power connector for 15 / 24 / 90watt 24VDC power supply. Note only 1 supply is
required to power both units. Either side can send power to the other unit. Note if LAN POE
is utilized for the non-amplifier models the 24VDC supply is not required.
IR –Plug IR receiver or emitter into this port. It will auto detect the mode of operation
required.
RS-232 –Connect RS-232 device up to 115k baud.
HDBaseT –Connect CAT 5e/6/7 cable. Shield cable is not necessary unless the environment
has a lot of electrically noise.
HDMI Output –Plug HDMI cable from destination device like an LCD display. Note the HDMI
cable should be rated for the bandwidth you are using.
Line In/Out –Line level input left and right on the top and line level output from the HDMI on
the bottom. The input and output are balanced capable. The line input can be mixed with the
line output for applications like wireless microphone receiver or paging. Using RS-232
commands locally or remotely the volume and mixing can be controlled. For the “L” models
IP commands can be utilized.
LAN1/2 –10/100 LAN connections. LAN1 can use POE from a POE switch to power both the
RX and TX units. These ports are a switch. Only 1 LAN port should be connected to another
switch. Note on theAmplifier versions POE will not work. External 60W 24V DC supply must
be used.
Relays –2 Normally Open Relays capable of handling up to 24V DC at 2A.
Amplifier –Left (L+, L-) and Right (R+, R-) 4/8 Ohm Outputs capable of 35 Watts per
channel. Amplifier version must use the 90 Watt desktop 24V DC power Supply.
Note: Some POE switch do not supply the full 15.4watts per port. Verify the total power rating of the switch. It should
be at least 15.4W x (number of ports).

IR EXTENDERS
IR Blaster IR Receiver
IR Connections
The DXE-CAT Series has the ability to auto detect on the IR port if a receiver or a blaster / emitter is connected.
IR Blaster / Emitter: Plug in an IR blaster to emit all IR command signals received from the IR receiver to control the associated
devices with built-in IR sensor
IR Receiver: Plug in an IR receiver to receive all IR command signals from the IR remote controls of the associated devices. Note
if you are not using an approved Aurora branded receiver make certain you do not exceed the 5v signal level
limitation as some devices use 12v. Failure to do so will result in damage.
When the DXE-CAT-TX2L is set for manual the only way to send IR commands is using IR files loaded on the ftp of the unit in the
IR directory. Aurora IR files (.wir) are available for download on the Aurora website. In addition, IR files learned from NX or QX
control devices can be utilized.
IR Jack Pinout
IR Blaster IR Receiver
Emitters must be mono plug or have ring and sleeve tied to ground.
Receivers must be stereo plug. Ring is 5v power. If using another brand receiver,
note carrier frequency must be stripped and IR signal cannot exceed 5v or
damage to port may occur.

IP SETUP
Introduction
The IP function allows the DXE-CAT-RX3C and DXE-CAT-RX3C-A to be controlled via LAN. In
addition, the units can be set up with built in setup pages and even serve up web pages to
remote devices on the network for control.
Default IP
The default IP out of the box is 192.168.1.10 static. Make certain to change the IP on the unit at
a time or you will get collisions on the network. Each device must have a unique IP address.
DHCP can be used but it is recommended to issue IP address based on the MAC address. This
assures the DHCP does not reassign the IP address at a later time causing issues. Keep in
mind the processor is on the TX unit so only the TX needs to be connected when you are doing
the initial setup although having the RX will not affect the process and may be necessary only if
the LAN is connected at the RX side.
To access the settings via web browser use the units IP address/setup (ex. 192.168.1.10/setup)
The default user name is admin and the default password is admin.
In the event you lose your settings press and hold the setup button on the DXE-CAT-RX3C /
RX3C-A for 3 seconds. This will restore the unit back to factory default.
Usage
Only serial port 1 will be used to communicate to the RX3 at a baud rate of 115200. This baud
rate will be fixed but the ports for the RX3 must still be set up accordingly to the correct baud
rate to match the device they are connected to.
The !30PTL,x<cr> command must be sent first to pick which port (1 = HDBaseT or 2 = Local
RS-232) before sending a serial command out a port.
