INTRODUCTION
The XTENDEX®Low-Cost HDMI Over Gigabit IP Extender with IR and POE multicasts digital video and audio signals to one or
more receivers up to 394 feet away over a 1000 Base-T Gigabit Network connected with CAT6/6a/7 cable.
Each Low-Cost HDMI Over Gigabit IP Extender with IR and POE consists of a local unit that connects to an HDMI source, and a
remote unit that connects to an HDMI display. The local and remote units can be connected together for a Point-to-Point
connection via CATx or a Point-to-Many connection via a network switch. Support for multiple transmitters requires a managed
network switch.
Features
Supports HDTV resolutions to 1080p.
oExtend up to 394 feet (120 meters) with CAT6/6a/7 cable.
oExtend up to 328 feet (100 meters) with CAT5e cable.
Cascade network switches to extend the length long distances.
oUp to three switches can be cascaded.
oThe max cable length between the first switch/transmitter and the last switch/receiver is 1,575 feet (480 meters)
for CAT6/6a/7 or 1,312 feet (400 meters) for CAT5e cables.
oThe max cable lengths between switches is switch dependent, but 394 feet (120 meters) is typical with
CAT6/6a/7 cable.
Power over Ethernet (PoE) –power supply not required at the local or remote unit.
Ideal solution for digital signage applications.
Broadcast real-time HDMI video and audio signals to multiple display locations with a managed or unmanaged (also
known as non-managed) network switch.
Transmits an HDMI signal over one CATx cable.
Full Infrared Remote (IR) control of HDMI source from remote HDTV using existing source remote control.
Plug-and-Play installation allows receivers to find the transmitters automatically on the same subnet. (Network
configuration may be required for managed network switch.)

Inexpensive CATx cable replaces bulky video cables.
Supports 1000 Base-T Ethernet connection.
Built in default EDID table.
HDMI 1.4 and HDCP 1.4 compliant.
Support for multiple transmitters requires a managed network switch with VLAN support. Standard LAN switches can
only support one transmitter.
oThe managed switch must support port-based IEEE 802.1Q VLAN.
oEach VLAN acts as a separate HDMI Over IP Channel on the network.
Each VLAN channel supports one transmitter.
oNumber of local and remote units that can be used is dependent on the backplane bandwidth of the switch.
For a point-to-many connection, a standalone network with an unmanaged network switch, hub, or router can be used
instead of a managed network switch.
oUp to 253 receivers supported.
oIt is not recommended to use any other network devices on this standalone network as it may cause a
degradation in performance.
Local and remote units must be in the same LAN. The units do not support WAN connections.
NOTE: ST-IPHD-POELC-V4 models are NOT compatible with ST-IPHD-POELC(-CLR) models due to different chipsets
being used.

INSTALLATION
Point to Point Connection
The Local and Remote Units can be connected directly to each other with CAT5e cable up to 328 feet (100 meters) long or with
CAT6/6a/7 cable up to 394 feet (120 meters long). When connected in this manner (without a POE-enabled switch between
them), a PWR-SPLY-IPHDPOELCV4 will be required at each end to provide power (sold separately).
If the IR feature will be used, connect the IR Receiver to the Remote Unit, and the IR Emitter to the Local Unit
Connect the video source and display to the Local and Remote Units using HD-xx-MM cables for best performance.

Many-to-Many Configuration of ST-IPHD-POELC-V4 Extenders
A Many-to-Many configuration of the ST-IPHD-POELC-V4 extender allows multiple senders and multiple receivers to be
connected to a single managed network switch wherein the switch can provide the routing of signals from senders to receivers.
Through the assignment of VLAN groups, a sender can send video to multiple receivers within the same-named group.
Note: Only one sender can be connected per group.
Be sure to take note of which ports belong to each group assigned. Once the group is created, simply plug the sender and the
receivers for the displays that are intended to receive video from the video source connected to the sender. The following
procedures provide examples of just such a configuration.
Procedure to create a VLAN group for Cisco SG350 Series.
1. Connect an Ethernet cable between the PC and OOB port on the Cisco switch. The OOB port is the rightmost port on
the front panel of the Cisco switch with an “OOB” label. (If your managed Cisco switch does not have an OOB port, just
connect the PC to any Ethernet port on the switch.)
2. Change the PC’s IP to be in the 192.168.1.x subnet.
3. Log into the web interface of the Cisco switch by visiting http://192.168.1.254 (the default IP of the switch).
4. Select “VLAN Management” on the leftmost list of the webpage.
5. In “VLAN Settings”, click “Add..” to create a new VLAN group. (You could repeat this step to create multiple VLAN
Groups.)
a. In the pop-up window, type a number between 2 and 4094 as the “VLAN ID” of the group. You could use any
name you want for the “VLAN Name”.
b. Click “Apply” to finish adding a new VLAN group.
6. Under “VLAN Management”, click “Interface Settings”.
a. If you see that the “Interface VLAN Mode” of the ports that you want to set up for your video extender are
already set to “Access”, you could skip this step and go to step 7.
If you see that they are set to “Trunk”, continue to step 6(b).
b. Choose a port you want to use, then click “Edit” on the bottom of the table.
c. In the pop-up window, change the “Interface VLAN Mode” from “Trunk” to “Access”. Click “Apply”.
d. Repeat step 6(b) and 6(c) to finish setting up all ports that you want to use.
7. Under “VLAN Management”, click “Port VLAN Membership”
a. Select a port you want to use, then click “Join VLAN..” at the bottom of the table.
b. In the pop-up window, assign the “Access VLAN ID” of the desired VLAN group ID number for this port to be
part of. Click “Apply”.
c. Repeat step 7(a)-(b) to set up all ports that will be part of that group.
8. Repeat steps 5-7 for all VLAN groups that you want to create.
Now your VLAN groups should be configured correctly and ready for use.

NTI XTENDEX Low-Cost HDMI Over Gigabit IP Extender with IR and POE
Procedure to configure VLAN groups for a Netgear Managed Network Switch.
1. Connect an Ethernet cable between the PC and any Ethernet port on the Netgear switch. If your Netgear switch has a
management port, use the management port instead.
2. Change the PC’s IP to be in the 192.168.0.x subnet.
3. Log in to the web interface of the Netgear switch. (The switch we used has a default IP of http://192.168.0.239.)
4. Click the “Switching” Tab, and then go to “VLAN”, “Advanced”, and “VLAN Configuration”.
5. Under “VLAN Configuration”, enter a VLAN ID (an integer between 2 and 4087) and a VLAN Name (whatever is preferable) in
the textboxes as shown in the picture above. Click “Add” and then “Apply”. You should see the page like shown in the picture on
the next page. A new VLAN group is added.

7. Under “Advanced”, click “Port PVID Configuration”. Check the ports designated in step 6. In the textboxes at the top of the
table, enter the VLAN group ID to the “PVID” and the “VLAN member” fields. Click “Apply”.
8. Now you should see a page as shown in the picture below, with PVID and VLAN member fields updated for g5, g6 and g7.
9. Repeat steps 5-8 for other VLAN groups that you want to create. Now your VLAN groups should be configured correctly and
ready for use.
