1.0 Introduction

1.1 General

The HHD264 is a family of HDMI over LAN Senders (encoders) and Receivers (decoders) that utilize advanced encoding with user definable bit-rates to distribute multiple Full HD video signals on a Gigabit 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.

Model	Description	Supports PoE	Power Supply
HHD264-S	HDMI, IR and RS232 over LAN Sender	No	Included
HHD264-R	HDMI, IR and RS232 over LAN Receiver	No	Included
HHD264-S-PD	HDMI, IR and RS232 over LAN Sender PoE powered	Yes	Included
HHD264-R-PD	HDMI, IR and RS232 over LAN Receiver PoE powered	Yes	Included

All devices come with a power supply. The PoE (-PD) versions also include a power supply is case PoE is not available on the network.

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 to 120 meters (400ft).

Figure 1.1 - Example of Matrix setup (many sources to many displays)

For installations having multiple senders and receivers a dedicated Gigabit (1000 BaseT) network (multi-port router) is recommended. 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.

Figure 3.1 - Example of Point-to-Point

Point-to-Many (Splitter) and Many-to-Many (Matrix)

Start by setting unique Multicast Group channels for the Senders prior to connecting them to the network. Do this even if you are planning to ignore the dip switches for normal operation (as explained in section 4.2). Receiver Multicast Groups are not of concern, but it is best to start by not having channel conflicts on the Senders.

Dip switch settings are covered in detail in section 4.2, but here is a “cheatsheet” for the first 8 channels

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.

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.

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.
• 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

HHD264

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.

Figure 3.2 - Example of Point-to-Many
Sender has an HDMI output that can be connected to a local display (not shown)

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.

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 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).

Figure 3.3 - Internet (TCP/IP) Properties

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.

4.0 Configuration & Operation

4.1 Sender's Front Panel

Figure 4.1 - Transmitter's Front Panel

HDMI IN: Connect to the HDMI source such as a DVD or Blu-ray player.

HDMI OUT: This is a local HDMI loop out for monitoring

IR OUT: Connect to the supplied IR emitter cable. The IR emitter jack supports Hall Research's CIR-EMT and CIR-EMT2 cables.

1000BT: Connect to a gigabit network router/switch or a Receiver using CAT5e/6 cable. The green LINK LED illuminates to represent the link from Receiver has established.

5V DC: Plug the supplied 5V DC power supply to the unit and connect the adaptor to an AC outlet and the LED will illuminate.

4.2 Sender's Rear Panel

Figure 4.2 - Transmitter's Rear Panel

RS232: Connect to a PC or Laptop with a straight thru DB9 male to female cable for serial communication.

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

Figure 4.3 - DIP-Switch Settings

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.

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 ^TM 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!

6.0 Group ID Setup for TX and RX

The Group ID for HHD264 can be setup using 4 methods – DIP-switch, WEBGUI, Windows™ GUI and Telnet command.

Figure 6.1 - Group Setting in WebGUI and DVM Windows™ Software Tool

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.

7.0 RS232

RS232 communication in HHD264 is bi-directional. The controller or the controlled device can be either at the Sender's or the Receiver's end. The baud rate for the TX and RX can be configured using the DIP switch, WEBGUI and the Windows GUI. The RS-232 pin-outs are shown below.

Scaler Settings These settings are only in the Sender (See Section 10)

• Scale Full HD to: In order to decrease the network traffic, if the input video is FHD 1080p source, then select this to downscale it to High Definition (HD) and Standard Definition (SD).
• Scale HD to: This downscales the HD input video to Standard Definition (SD).

Encoder Settings These settings are only in the Sender (See Section 10)

• Full HD Bit Rate: The bit rates range from 10000-18000 Kbps for FHD (1080p) input video.
• HD Bit Rate: Select from the range between 8000 and 16000 Kbps for HD(1080i & 720p) input video.
• SD Bit Rate: Select from the range 2000-8000 Kbps for SD (576p, 576i, 480p & 480i) input video.

Video Information These settings are only available in the Sender WebGUI

• Input Resolution: Shows the HDMI source's resolution to the HDMI input of the transmitter.
• Input Frame Rate: Shows the refresh rate of the source.

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.

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".

Resolution	Bit Rate – Range (Kbps)
1080p (FHD)	10000-18000
720p, 1080i (HD)	8000-16000
480p, 480i, 576p, 576i (SD)	2000-8000

10.0 Telnet Commands - Transmitter and Receiver

HHD264 offers excellent control features where the user can obtain information from each unit such as Group ID, Name, IP configuration, etc. from a remote location.

• Telnet operation via specified port 9999 can be achieved by connecting the sender and receiver in a dedicated telnet session.
• Open the telnet session using a terminal software program.
• Type "Telnet 192.168.x.x 9999" to ping the sender or receiver.
• Commands are case sensitive.
• Use lowercase characters.
• Invalid command is responded with "Unknown Input Command".
• "list " displays all the commands.

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.

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..

12.0 Power over Ethernet (PoE)

The HHD264 Senders and Receivers with -PD suffix can utilize Power Over Ethernet (PoE) eliminating the need to connect a power supplies to the unit. The device gets its power from the PSE (Power Sourcing Equipment) port in the Gigabit PoE switch. The -PD units also include power supply in case needed.

13.0 Firmware Upgrade

The firmware upgrade on HHD264 can be completed using the WEBGUI. Contact Hall Research for more details.

14.0 Recalling Factory Defaults

Factory defaults resets are parameters (including network settings) back to default. There are 4 ways to recall factory defaults:

1. Press the RESET button on the unit for 10 seconds.
2. Use telnet command "factory reset"
3. Factory Default is available on the Software GUI. Wait for 10 seconds for the device to reboot and activate.
4. WebGUI also offers factory resetting the device.

15.0 Troubleshooting

There are no field serviceable parts or circuits in the device. If you think the device is malfunctioning (or you have no picture output), please try to use the following methods to obtain a picture first.

15.1 Getting a Picture on the Output

• If there is no picture on the display, you can “quick press” the RESET button on the unit’s panel to reboot the device while keeping the current IP settings intact.
• If you still have issues, try factory resetting the unit by holding the RESET button on the panel for 10 seconds. All the settings will be erased and set to factory default.
• In a one to many and many-to-many configuration, if there are displays with different native resolution and there is no picture on some displays, then it is highly recommended to use the “Scaler Settings” in the TX’s WebGUI.

For example, if there is a 1080p HDMI source connected to the transmitter and a 720p monitor is present among many1080p monitors connected to other receivers, then select scale “Full HD to HD” in Encoder Settings in the web page so that all the monitors get a resolution of HD 720p video, thereby, resulting in an image. Once you have an image, you can check up the OSD menu if necessary. If you still have trouble in getting the picture on the output, make sure all the cables are connected to the HHD264 and the gigabit switch/router.

15.2 Contacting Hall Research

If you determine that your HHD264 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.
