HDMI and USB Extension on single CAT6

1.0 Introduction

The EX-HDU is used to extend HDMI video and USB data on a single Cat6 cable
up to 200 ft (60 meters). HDMI audio is extracted and is provided both as analog
stereo and multi-channel digital. The EX-HDU can also be used to control other
equipment by providing programmable contact closure I/O, RS-232 output, IR
output, and optional LAN interface with internal WebGUI and IP control.

The EX-HDU extender consists of an EX-HDU-WP single-gang wall plate
transmitter and an EX-HDU-R (or EX-HDU-R-IP) receiver. They connect using
standard CAT5e/6 UTP cabling up to 200 feet (60 Meters) long.

The wall-plate Sender gets its power from the Receiver via the same UTP cable
and does not need a separate power supply. For convenience, the wall plate
features a USB hub with two USB ports for connection of USB devices. The plug­and-play extender is compatible with all PCs, MACs, and Android Tablets and
does not require driver installation. Simply plug the PC's HDMI and USB ports to
the sender and make them available at the remote receiver.

The Receiver provides HDMI video output, stereo audio output, 4 USB ports, IR
output, and a terminal strip that has RS-232 output plus 4 programmable digital
I/O ports. A mini-USB port is also provided for configuration upload from a PC
for cases where the Receiver is used also as a control system.

Receiver with IP connectivity is the model EX-HDU-R-IP. It provides an
ETHERNET port for control via IP commands or internal webpage.

Users can upload RS-232 commands to the EX-HDU to control other equipment
such as turning a projector on and off. Commands can be triggered

automatically

by detecting video, or manually via the internal WebGUI, or by

sensing open and close contact events on the I/O ports.

3.0 Setup

Installation

• Connect the sender (EX-HDU-WP) and the receiver (EX-HDU-R) with a
CAT6 cable.

• Connect the HDMI source (such as video from a PC) to the wall plate's
HDMI input.

• Optionally, connect the wall plate's USB HOST (type B) connector to a
compatible HOST computer via the supplied cable.

• Optionally, connect compatible USB devices into the wall plate's USB hub
connectors or the USB HUB connectors on the receiver.

• Optionally, connect the HDMI extracted SPDIF audio output on the back of
the wall plate to a compatible audio device.

• Optionally, connect the receiver's 3.5mm analog audio output to
compatible device (e.g., headphones, assistive listening devices).

• Optionally, for controlling an external device (such as a Projector) via RS­232, use the TX, RX and GND contacts on the Terminal Strip.

• Optionally, Connect I/O devices to the Terminal Strip as required. See
section 4 for more details. Each of the 4 I/O ports can be configured to be
an input or output. When configured as an input, the device can sense
contact closure (or DC voltage). When a transition is sensed, the EX-HDU
can issue programmed actions. Actions can be any combination of RS-232
commands, IR commands or contact closure output state changes. When
an I/O port is configured as an output, it acts as an open-collector digital
output.

4.0 Connector and Indicator Functions

EX-HDU wall-plate Sender

1) HDMI Input - Connect Source Video to this Connector

2) Power Indicatior - Lights green when wall plate is powered up

3) Signal Indicator - Lights red when vide signal source is active

4) USB Host - If USB extension is needed, connect to Host USB (such as PC)

using the supplied USB A to B cable.

5) USB Hub Ports - These are available to the user. Connect USB 2.0

devices such as flash memory, printer, HD WebCam, keyboard, etc

6) Link RJ45 Connector - Use a Cat6 cable to connect to the Receiver.

b. SPDIF & GND - Digital Audio Output. This is the extracted

digital audio of the HDMI signal. It is simply deembedded
without any modification. It echos the HDMI audio and can be
stereo or multichannel

EX-HDU Receiver

1) IR Connector - This connector can be connected to a compatible IR

emitter cable (such as Hall Research CIR-EMT or CIR-KIT-EMT2). To
use this feature customers need to know the IR protocol and IR data for
the device they want to control. This information may be difficult to
obtain. Please refer to Software GUI User's Guide for more information.

2) USB Hub Ports - Use these connectors to plug USB 2.0 devices such as

touch screen, interactive displays or smart boards, printers, HD
WebCams, Keyboard/Mouse, etc

3) Analog Stereo 3.5mm Output. - Connect to headphones, audio amps or

other gear. If the source is sending multi-channel audio this output will
be muted since it only supports two channel audio.

4) HDMI Output

5) Power and Active Video indicator LEDs

6) Configuration Port - This port is used to configure the device when it is
going to be used as a controller. Connect this port to a Windows PC
running the free Windows configuration software (available for
download on the product's webpage)

7) RS-232 Port and 4 Digital I/O ports

a. The RS-232 port typically functions as an output and is used to

turn a projector on or off or control the volume of an external
audio amplifier. The RS-232 port can also be used as an input
to control the EX-HDU itself. For example, users can send a
command to the Receiver that causes it to issue a
corresponding IR output command. Please refer to Software
GUI User's Guide for futher information and command list.

b. The 4 digital I/O ports each have a signal and a ground contact

(G indicates ground). For convenience a 5v output is also
provided (with 80ma of maximum current available).

Each of the I/O ports can be configured to act as an input or as
an output. When configured as input, they can sense high/low
signal transitions or open/close contact events. System can be
programmed to issue RS232 or IR commands based on those
transitions. For example a simple external toggle switch can be
used to issue on and off commands to a projector. Note that
commands can also be triggered by detecting video, so the
on/off command functions can be automatic.

When the I/O ports are configured as output, they behave as
Open Collector (similar to contact closure) and can withstand
upto 30V DC in open state. These ports can be used to control
equipment such as motorized projector screens.

8) Optional LAN Port - This connector is only functional on the Receiver

with the IP control option (EX-HDU-R-IP). Users can configure an
internal Web GUI with buttons to control the unit or peripheral
equipment. Please refer to Software GUI User's Guide for futher
information.

9) Link RJ45 Connector - Connects to the corresponding LINK port on the

Wall Plate Sender.

10) Power Input - Connects to the power supply provided

5.0 Troubleshooting

If you are experiencing problems getting the extender to work properly, please
use the following troubleshooting suggestions.

• Ensure that all connections on both the sender and the receiver are
solid. Loose connections are the number one cause of issues.

• Try resetting the system by unplugging the power supply, waiting 5
seconds and plugging it back. Both the red and green LEDs on the EX­HDU-R shall illuminate.

• Try restoring factory defaults using the Windows GUI or via RS-232
command.

Contacting Hall Research

If you determine that your Extender is malfunctioning, do not attempt to repair
the unit instead, contact Hall Research Technical Support at 714-641-6607. To
return the unit to Hall Research you must first get a Return Authorization
(RMA) number. Package the unit carefully, if returning. We recommend that you
use the original container.

NOTE Backup any existing device configuration using the Windows™

GUI Prior to resetting factory defaults as any user programmed
command strings will be erased.
