1.0 Introduction
1.1 General
The FHD264 is a family of HDMI over LAN Senders (encoders) and Receivers
(decoders). They utilize advanced video encoding techniques and can
distribute up to 64 Full-HD video signals to hundreds of displays on a simple
1 Gigabit local area network (LAN). Senders and Receivers can also extend IR
remote control signals and Full duplex Serial RS-232 communications.
Each device provides a two-line front panel LCD that can be used to easily
configure or monitor parameters such as IP settings, multicast group
selection, assignment of device names, and more. This eliminates the usual
installation challenges of finding and configuring devices on the network for
the first time. With the front panel LCD, users can see and assign
configuration parameters with ease.
HDMI Audio is extracted and available as convenient 3.5mm sterefo analog
output on both the FHD264 Sender as well as the Receiver. The FHD264-S
Sender also provides local HDMI output.
The RS-232 serial port on each device can be used in SoIP mode (Serial over
IP) allowing IP controllers on the network to communicate with and control
peripheral equipment such as Display and projector using Serial Commands.
All devices support IEEE 802.3af PoE (Power over Ethernet). When
connected to a network switch with PoE, no external power supply is
required. A power supply is included for customers that may not have PoE on
their network.
The FHD264-R Receivers can decode the video from any Sender on the LAN.
It is easy to switch the Receiver between Senders. This can be done in
several ways:
•Using front panel LCD and push buttons
•Using supplied IR Remote Control
•Browsing to the WebGUI in each unit
•Telnet Commands (ideal for third-party control of switching)
•Windows™ PC running DVM Manager Tool software
(free download)
•CNT-IP-264 (Optional Network Controller module
that can globally control all FHD devices and third
party devices on the network)
Receivers include an IR remote controller for switching among
Sender channels (multicast groups). In installations such as sports bars,

users can easily switch the monitor to another source using this IR remote. In
addition, since the FHD264 extends IR signals, users can control sources
such as video players using that device’s original IR remote. In other words,
from the Receiver location (at the TV), you use the included IR remote to
switch the video to a different Sender, then you can use
the IR remote of whatever source is connected to the
sender.
Receivers also offer Fail-Safe automatic video routing
and redundancy. So if the receiver is not detecting any
video on its currently assigned channel, it will switch to
a user defined alternate channel. It can also automatically switch back to the
original multicast channel if video is detected again.
Senders are available as a stand-alone box. Rack mount hardware is also
available for housing up to 12 senders in 4U rack space.
FHD264 applications include digital signage, meeting rooms, classrooms,
bus & metro stations, airports, home theater, and more.

3.0 Installation
For installations having multiple Senders and Receivers, a dedicated Gigabit
(1000 BaseT) network with PoE and IGMPV2 Support is required. The H.264
encoding scheme allows user-definable bit rates to give users control over
bandwidth used for each video stream. Use CAT5e/6 cables to extend up to
394 ft (120 meters).
3.1 Configuration
FHD264 system supports multiple configurations: point-to-point (one Sender
connected to one Receiver without network switch), point-to-many (one
Sender to many Receivers like a video splitter), and many-to-many (matrix
operation). Typically, both point-to-many and many-to-many configuration
requires a network switch.
3.1.1 Point-to-Point
Point-to-Point is the straightforward configuration of FHD system without
involving a network switch. An external power supply is required to supply
power to both Sender and Receiver. The only requirement is that the TX and
RX should have unique IP address (Static) and need to be in the same group.
Figure 2 - Example: Point-to-Point
3.1.2 Point-to-Many (Splitter) and Many-to-Many (Matrix)
Start by setting a unique IP address (if not using DHCP) and Multicast Group
channel for each of the Senders (see the front panel operation in Section
4.2.) Duplicate IP addresses and Multiple Senders on the same Group will
cause conflicts. Receivers must also have unique IP addresses, but can point
to the same Group channel.
Receivers with the same group number as a Sender will show the video from
that Sender, and 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 a given channel, but many Receivers can be tuned
to that same channel.

As shipped, each device is configured for DHCP. In this mode, when powered
up each box gets its IP address from the DHCP server on the network.
Alternately, the IP addresses can be assigned manually and set to Static
from the front panel. To change IP address using the PC-GUI, connect a
Windows™ PC or laptop to the network and run the free DVM Manager Tool.
Figure 3 - Example: Point-to-Many
3.1.3 Setup
1. To get started, use a Gigabit Switch with DHCP server and IGMPV2
Support (Recommended)
2. If the switch does not support PoE, use the power supply included in the
package (-S and -R) to power the FHD.
3. By default, DHCP is enabled in both Sender and Receiver. The default IP
address of the Sender is 192.168.1.11 and Receiver is 192.168.1.12.
(See Section 5.11 Factory Defaults for more details.)
4. If the switch supports DHCP, connect the Senders(s) using CAT5e/6
cable.
5. If the switch does not support DHCP, connect the Sender(s) (one at a
time) using CAT5e/6 cable and assign unique static IP address to each
device by turning OFF DHCP. (See Section 4.2.1 Changing IP address
from Front panel). Repeat the same step for all the Receiver(s).
6. Make sure each Sender has a unique Group ID. Note that, two Senders
cannot reside in the same Group ID. This will cause conflicts.
7. Connect HDMI source(s) to the HDMI input of the Senders(s).
NOTE A Gigabit(1000BaseT) Switch with DHCP server, IGMPV2 and PoE is
recommended. When there is more than one Sender on the network in a matrix
configuration (multipoint-to-multipoint) the Ethernet Switch MUST support: IGMP to
prevent network flooding.
Hall Research recommends using the Cisco SG300 Series of gigabit Ethernet Switches.

8. Connect the HDMI loop output of the Sender(s) to local HDMI display(s)
if desired.
9. Connect the HDMI display(s) to the Receiver(s) output and change the
Group ID of the Receiver(s) as required. To receive the video, both Sender
and Receiver must be in the same group. (If there is any problem with the
video, see FAQ Q2: No picture on the display.)
10. If using IR, connect the IR emitter cable into “IR OUT” port of the Sender,
and connect the IR detector cable into “IR IN” port of the Receiver.
11. If using RS-232, connect an RS-232 cable from the PC or automation
system to the supplied phoenix connector, and then connect it to the RS-
232 port on the Sender. Repeat the same process between the Receiver
and the device to be controlled. Note that the baud rate is selectable and
should be the same at both Sender and Receiver end. (See Section 4.1
Front Panel Operation for more details.)
12. Once the Senders and Receivers are configured properly on the network,
they will be discoverable by Hall Technologies’ DVM Manager Tool.
Simply plug a laptop or PC into the same router/switch and run the free
Windows™DVM Manager Tool. You can easily assign user-friendly
names to each device and change the Group routings.
13. To use the DVM Manager Tool to control video routing, first scan for the
devices. Note that if the switch does not support DHCP, then the IP
address of the PC also needs to be changed to static (See FAQ Q3: How
to Change the IP address of the PC?)
14. To access the internal WebGUI of FHD264, type the IP address into the
address bar of any standard browser. By default, as shipped from the
factory, no login is required to access the internal WebGUI. If login is
enabled, the default user name/password is admin/admin.

5.0 Features
5.1 Device ID
Each FHD264 Sender and Receiver can store a custom name of up to 31
alphanumeric characters. Naming the device is very useful in managing large
installations. The Device ID will be displayed on the front panel home screen,
OSD, WebGUI and FHD software applications. The default Sender name is
HRTVTX and Receiver is HRTVRX.
5.2 Group ID
A Group ID is a number range from 0 to 63, which the Sender uses to
multicast its video and data to a group of Receivers on the network. Each
group ID is linked to a multicast IP address. You can have a maximum of 64
sources (Senders) in the network. Note that there is no limitation on the
number of Receivers that can connect to a Group if they have a different IP
address.

its group
"Connected" -- TX found and receiving video
If the Receiver is connected and there is no HDMI source
at the Sender end, the following video will be generated
by the Sender by default.
5.4 RS-232
RS-232 communication in the FHD264 is bi-directional and
it is achieved using Serial Over IP(SoIP) Protocol. The
controller or the controlled device can be either at the
Sender’s or the Receiver’s end. Note that the Sender and
Receiver should have matching baud rate for
communication. The baud rate for the TX and RX can be
configured from Front Panel, WebGUI, or the Windows™ GUI.

Figure 14 - RS-232 Communication
5.4.1 Working
When a serial device connected to the sender transmits data, it is received by
all the receivers in that group. If a serial device connected to the Receiver
transmits data, it will be received only by the Sender in that group. While
receiving data from multiple Receivers, the Sender receives the data on a
first come, first served basis and the receiver might not send all the data in
single IP Packet. To effectively parse the response from multiple serial
devices connected to the sender, enable Packet Mode at the Sender
(FHD264-S) and add Message Complete Delay (MCD) at the Receiver
(FHD264-R).
Packet Mode at the Sender will append a SOIP header for each chunk of data
received from the receiver. To avoid the fragmentation of SOIP messages
from the receiver use Message Complete Delay (MCD) at the Receiver end.
MCD tells the receiver to buffer the bytes received from the serial device
locally for certain period of time, until Serial device stops transmitting or
Buffer is full.
See Application Notes on Packet Mode & Message Completion Delay for more
information.
5.5 Serial Over IP (SoIP) from External Devices
Serial devices connected to the RS-232 port on FHD264 units can be
controlled over the IP network. SoIP commands can be issued via Telnet,
which is simplex (See the telnet command "rs_out" in telnet control).
