1.0 Introduction
1.1 General
The HHD264 is a family of HDMI over LAN Senders (encoders) and Receivers
(decoders) that utilize the latest H.264 encoding with user definable bit-rates to
distribute multiple Full HD video signals on the local area network (LAN) with
unparalleled clarity and performance. The devices also extend IR control and bi-
directional RS-232 communication.
An important feature of the system is its ability to switch Receivers on the fly to
show the video of any Sender on the network using Hall Research’s DVM
(Dynamic Virtual Matrix™) technology. Switching is accomplished by using:
Dip Switches on each device (for easy set-and-forget)
Built-in Webpage (WebGUI) in each unit (accessible from any browser)
Telnet Commands (ideal for third-party control of switching)
Using a PC running Hall Research’s free Manager Tool software
Senders and Receivers are available with and without POE capability.

All devices have a power input connector. The PoE (-PD) versions can still be
used with non-PoE routers by plugging in a power supply.
The HHD264 systems support several modes of operation: point-to-point (one
sender connected to one receiver with no LAN infrastructure), point-to-many
(one Sender to many receivers like a video splitter), and many-to-many (matrix
operation). They support CAT5e/6 cable distances of up to120 meters (400ft).

For installations having multiple senders and receivers a dedicated Gigabit
(1000 BaseT) network (multi-port router) is recommended. The system also
works on slower 100 BaseT networks but with fewer sources. The H.264
encoding scheme allows user definable bit rates to give users control over
bandwidth used for each video stream.
The HHD264 system applications include digital signage, meeting rooms,
classrooms, bus & metro stations, airports, home theater, and more.

3.0 Installation
3.1 Configuration
Point-to-point
When connecting point-to-point, there is no need for any IP configuration for
the TX and RX. The only requirement is that the TX and RX need to be in the
same group by having the DIP-switch positions same on both devices.
Point-to-Many (Splitter) and Many-to-Many (Matrix)
For simple installations where video routing is permanent (static) and you don’t
expect to switch the video connections after installation, simply use the dip
switches to set the multicast group numbers on each device. Remember, each
Sender must have a unique group number. All Receivers with same group
number as a Sender will show the video from that Sender (also RS-232 and IR
are routed between them). To use a broadcast TV analogy, Multicast Group
numbers are like TV channel numbers. Only one station can broadcast on any
particular channel, but many Receivers can be tuned to that channel.
As shipped, each device is configured for DHCP. So once powered up, each box
gets its IP address from the DHCP server on the network. You can change the IP
addresses to Static and assign a different address if you desire. To do so, first
connect a Windows™ PC or laptop to the network and run the free DVM
Manager Tool.
Hardware setup
•Connect source(s) to the HDMI input of the Senders(s).
•Connect the HDMI loop output of the Sender to a local HDMI display if
desired.
•Connect the Sender(s) to the switch/router with CAT5e/6 cables.
NOTE
A Gigabit Router or Switch with DHCP server is recommended and when
there are more than one Sender on the network in a matrix configuration
(multipoint-to-multipoint) it is required that the Ethernet Switch support:
Gigabit Ethernet, DHCP Server, and IGMP. Hall Research recommends
using the Cisco SG300 Series of gigabit Ethernet Switches.
Figure 3.1 - Example of Point-to-Point

•Connect all the Receivers and the switch/ router with Cat5e/6 cables.
•Connect the HDMI displays to the Receiver outputs.
•If using IR, connect the IR emitter cable into “IR OUT” port of the Senders;
and connect the IR detector cable into “IR IN” port of the Receiver.
•If using RS232 (Bi-directional), connect a straight thru DB9 cable from the
PC or automation system to the RS232 port on the Sender; and connect a
cable from the Receiver to the device to be controlled. Set the baud rate dip-
switches to match the device you want to control. Note: you can change the
baud rate from the WebGUI or Windows™ manager tool as well. In that case
the dip-switch setting on the devices will be ignored. (see Section 7.0).
•Set the Multicast Group number dip-switches on the Senders so each has a
unique address. As with baud-rate, you can override the dip-switch setting
on the box by using WebGUI or Windows GUI (See Section 8.0). Even if you
are going to control the group settings from GUI, it is best to start by having
unique Group settings on each Sender’s dip-switch. The Windows GUI can
help in showing you how to set the dip-switch positions (so you don’t have to
do binary calculations!).
•If devices are not PoE, connect the included power supplies to each device.
3.1.2 Setting the IP address
(A) DHCP - Default
In order to use the DHCP feature, you must have a compatible DHCP ROUTER
OR SWITCH that will assign the IP addresses to the TX and RX devices.
Once the Senders and Receivers are connected to the network, they will get
assigned an IP address that is part of the network and easily discoverable. Then
you can simply plug a laptop or PC into the same router/switch and run the free
Windows DVM Manager Tool. You can assign names to each device and change
the Group routings.

Sender has an HDMI output that can be connected to a local display (not shown)

If you will be using the Hall Research DVM Manager Tool to control video
routing for your application, then there is no need to change the IP settings to
Static. This is because even if the IP address inadvertently changes (since it is
DHCP), the Manager Software does not care since it uses Multicast Group
numbers and user specified names for each end-point. You won’t have any
problem routing the video from the tool. However, if you want to put shortcuts
to each Receiver’s IP address on your smart phone or PC in order to use the
internal WebGUI of each Receiver to change the video being displayed, then
having DHCP can become detrimental. This is because the IP address may
change and therefore the shortcut links will be wrong.
In general we recommend that you change the IP settings of each box to Static.
(B) Setting STATIC IP
If your network supports DHCP server function: Simply use the Hall
Research DVM Manager Tool. You get a list of all Senders and Receivers, you can
give them meaningful names, change IP settings and more.
If your network doesn’t support DHCP server function: Then you have to
change the IP addresses for each TX and RX manually using the WEBGUI in each
device. Without DHCP Server, the default IP address of the TX is 192.168.1.xx
(typically xx=11) and the RX is 192.168.1.yy (typically yy=12)
By default as shipped from factory, no Login is required to access the internal
WebGUI. But if Login is somehow active the default user name is admin and the
password is admin.
Step 1: Access the Network Setting Control Panel in Windows™ and locate your
LAN connection. Typically it is located at Start Control Panel Network
Sharing center Change adapter settings Properties Internet
Protocol Version4 (TCP/IPv4). For example, change the IP address field to
192.168.1.100 (0-255, except 11 or 12) and press "OK" to save the configuration
(as shown below).

Step 2: Use an Ethernet Cable to connect the PC (or laptop) and the extender.
Make sure that the power LED (Red) for the extender and the network link
status LED (Green) is blinking.
Step 3: Open a browser and enter the default IP address of 192.168.1.xx (xx=11
for TX or 12 for RX). You can now change the IP to be Static and change the
address as you like.
Step 4: Click “Update Settings” in the Network Settings.
Step 5: Click “Reboot” in the Upgrade Section.

BAUD:Dip-switch positions define a 3 bit binary number. When it is held UP, it
is “0” and when held down, its value is “1”. So there are a total of eight
combinations and each denote a baud rate in bits per second (bps) as below
000 = 2400 (default)
001 = 4800
010 = 9600
011 = 19200
100 = 28800
101 = 38400
110 = 57600
111 = 115200
MULTICAST GROUP:The 6 position dip switch is used to assign the group
number (channel number) video is cast on the network. Similar to the baud Dip-
switch, it is set from left (least significant bit) to right (most significant bit).
Again, if you use the Windows™ GUI tool you will have a graphical image of the
dip switch making it easy to set.
RESET:This button has two uses. Press it momentarily to cause a reboot (same
as power cycle). Press and hold for 10 seconds to restore factory defaults.
Figure 4.3 - DIP-Switch example
NOTE
The DIP setting order is from right to left. As shown in the example above.
The Windows™ GUI gives you graphical image of the dip switch making it
easy to set the switch.
NOTE
You have the option to completely ignore the dip-switches!
As mentioned earlier both Baud Rate and MultiCast Group/Channel number
can be set in both WebGUI of each unit or the Windows™ tool. So why have
dip switches at all?
By default when units are powered up the devices revert to the dip-switch
positions. This may be useful in certain situations. For example: if there is a
power interruption or outage in the building you can make sure the system
comes up in a known state every time (as determined by the dip-switches).
Having dip-switches also speeds up installation of a simple, static system
without worrying about IP configuration. Just set the dip-switches to pair
Receivers & Senders and you are done.
There is a setting in the WebGUI of each device to ignore the dip-switches
on power up and recall the previous setting from memory.
When this option is selected, the dip-switches perform no function whatsoever!

The Group ID for HHD264 can be setup using 4 methods – DIP-switch, WEBGUI,
Windows™ GUI and Telnet command.
6.1. Use DIP Switch On Power Up – Group ID
The “Use DIP Switch on Power Up” feature allows the user to have a control on
the Group ID settings if there is a power interruption. By enabling this option,
the HHD264 uses the DIP switch position after power up. When not selected,
the unit recalls the last setting prior to shutdown.

9.0 Encoder and Scaler Settings
The HHD264 has internal scaling capabilities. The user can control the bit rate
and the scaling feature depending on the network bandwidth. The user can
change the settings in three ways – WEBGUI, Telnet and PC GUI. Please consider
the following if you decide to change settings from default:
•The input of the sender is the source video fed into the sender.
•The output of the sender is the network stream.
•Reducing the bit rate will decrease the occupied bandwidth on the network.
•By default as shipped, these settings are optimized for the best image
possible without undue burden on the network.
NOTE
Contact your network administrator if you are unsure of how to configure
the existing network.

9.1 Encoder and Scaler Settings - WebGUI and PC GUI
If you are using a source with 1080p resolution, then use “Scale Full HD to :”
option to either transmit the video at the same resolution on the network, or to
first downscale the video from Full HD to HD (or SD) and then transmit the
lower resolution image on the network. By doing so you will force the unit to
use the bit rate for HD instead of Full-HD which is typically much lower bit rate.
Understand that you will be lowering the resolution from 1080p/60 to
720p/60. But if the video has a lot of motion and action, the compression will be
able to keep up better at 720p and still reproduce a clear image in the presence
of all large areas of moving objects on the screen.
However, if you have a Full HD (1080p) source video where the amount of
motion on the screen image is limited (such as a slide show), you can skip
scaling it down and just reduce the bit rate for Full HD. That way you are not
sacrificing any resolution of the original image.
If you are using a 720p source resolution, the use “Scale HD to:” option to
downscale the video to Standard Definition (SD) to transmit in the network.
Click “Update Scaler” to confirm the settings. See Figure 9.1.
Figure 9.1 - Sender Encoder and Scaler Settings in WebGUI and PC GUI
Once the Scaling Settings are confirmed, select the Full HD, HD and SD bit
rate in the Encoder Settings section and click “Update Encoder”.

11.0 EDID
The HHD264 offers EDID management meaning that the user can write a
custom EDID file into the device using the HDMI input of the transmitter,
HHD264-S. Hall Research’s EMX-HD-AUD audio extractor and EDID manager
works perfect to achieve this purpose.
12.0 Power over Ethernet (PoE)
The HHD264 comes with a Power Over Ethernet (PoE) solution that eliminates
the need to have a power supply for the unit. The device gets its power from the
PSE (Power Sourcing Equipment) port in the Gigabit PoE switch.
NOTE Factory resetting the HHD264 will restore back the default Hall Research
EDID to the device. The user must confirm the action and take all necessary
precautions to prevent loss of data. Hall Research is not responsible for any
damage that may occur from the user attempting to modify the EDID..
